Description

CROSS-REFERENCE TO RELATED APPLICATION

This application is a continuation application of International Patent Application No. PCT/KR2017/009078, filed 21 Aug. 2017, which claims the priority and the benefit of U.S. Provisional Patent Application No. 62/376,998, filed on Aug. 19, 2016, the disclosures of which are incorporated herein by reference in their entirety.

FIELD

The present invention relates to an artificially manipulated neovascularization-associated factor for regulating neovascularization and a use thereof. More particularly, the present invention relates to a system capable of artificially regulating neovascularization, which includes an artificially manipulated neovascularization-associated factor for regulating neovascularization and/or a composition able to be used in artificial manipulation of the neovascularization-associated factor.

BACKGROUND

Excessive neovascularization found in many cases of severe diseases occurs in diseases such as cancer, macular degeneration, diabetic retinopathy, arthritis and psoriasis. In such a state, new blood vessels are provided to tissue with a disease, resulting in destroyed normal tissue, and in the case of cancer, new blood vessels allow tumor cells to enter the circulation system and thus settle in another organ (tumor metastasis).
Particularly, since cancer cells receive nutrients through neovascularization and are metastasized to another organ, neovascularization is essential for growth and metastasis of cancer. It has been known that there is an actual close relationship between the density of capillaries generated in cancer tissue and probability of cancer metastasis in various types of cancer. In addition, rheumatoid arthritis, which is the representative disease among inflammatory diseases, is caused by an autoimmune disorder, however, during the development of the disease, chronic inflammation generated in the synovial cavity between joints leads to neovascularization, resulting in destroyed cartilage. Various ophthalmologic diseases leading to blindness in several million people in the world every year are also caused by neovascularization. As a representative example, diabetic blindness is a diabetic complication, and refers to an invasion of capillaries generated in the retina to the vitreous body through neovascularization, ending up in blindness. Therefore, neovascularization inhibitory substances may be usefully employed as therapeutic agents and preventive agents for various diseases such as cancer, rheumatoid arthritis and diabetic blindness, in which continuous neovascularization occurs.
Meanwhile, conventionally, inhibition of signaling of vascular endothelial growth factors (VEGFs) in order to inhibit neovascularization had been actively studied. However, in the conventional art, initially, neovascularization seemed to be inhibited, and then there was a side effect in which cancer cells became more aggressive because the pathway of an anticancer agent to the cancer cells was also inhibited.
As such, while a variety of studies to treat diseases induced by neovascularization are progressing, there is almost no fundamental method for treating such a disease.
Particularly, there is no method for treating a severe disease such as cancer or cancer metastasis caused by neovascularization, blindness caused by retinal or corneal degeneration, and therefore, there is an urgent demand for developing such a fundamental method for treating a neovascularization-associated disease.

The present invention provides an artificially manipulated neovascularization-associated factor for a specific purpose.
The term “neovascularization-associated factor” encompasses a variety of non-natural, artificially manipulated substances capable of having a neovascularization regulating function, which directly participate in or indirectly affect neovascularization. The substances may be DNA, RNA, genes, peptides, polypeptides or proteins. For example, the substances may be genetically manipulated or modified genes or proteins expressed in an immune cells. The neovascularization-associated factor may promote or increase neovascularization, or conversely, suppress or inhibit neovascularization.

DETAILED DESCRIPTION

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the art to which the present invention belongs. Although methods and materials similar or identical to those described herein can be used in practice or testing of the present invention, suitable methods and materials are described below. All publications, patent applications, patents and other references mentioned herein are incorporated by reference in their entirety. In addition, materials, methods and examples are merely illustrative, and not intended to be limitive.
One aspect of the present invention relates to an artificially manipulated neovascularization system, which has a regulated neovascularization effect.
Specifically, the present invention relates to combination of various aspects capable of regulating neovascularization or improving or treating a neovascularization-associated disease by artificially manipulating a neovascularization-associated factor. The present invention includes a neovascularization-associated factor whose function is artificially modified, a method of manufacturing the same, a composition including the same, and a therapeutic use thereof.
Another aspect of the present invention relates to an additional regulating system with a third in vivo mechanism, concomitant with various functions of a specific factor (e.g., a gene known as a neovascularization-associated factor, etc.) whose function is artificially modified.
Specifically, targeting of a third in vivo function as well as a neovascularization function in which artificially manipulated specific factors are involved may lead to the regulation of corresponding mechanisms. The present invention includes a neovascularization-associated factor whose function is artificially modified, a method for manufacturing the same, a composition including the same, and therapeutic uses thereof for improving or treating a disease associated with the third function.
Neovascularization
An exemplary embodiment of the present invention relates to improvement and modification of a neovascularization-associated system.
The term “neovascularization” refers to a process of tissue vascularization, including generation, development and/or differentiation of new blood vessels. Here, neovascularization encompasses angiogenesis and vasculogenesis. Neovascularization may be closely related to various factors to promote or inhibit proliferation of vascular endothelial cells.
Neovascularization encompasses all mechanisms for extension from existing blood vessels, new generation of blood vessels from precursor cells, and/or an increase in diameter of an existing small blood vessel.
In addition, neovascularization encompasses all mechanisms associated with formation of new vessels, which is involved in vascular leakage or repair of damaged blood vessels.
The vascularization includes mechanisms concomitant with excessive and/or abnormal neovascularization in various severe disease states.
For example, in diseases such as cancer, macular degeneration, diabetic retinopathy, arthritis and psoriasis, excessive neovascularization occurs. In such a disease state, new blood vessels are provided to tissue with a disease, and normal tissue is damaged. In the case of cancer, new blood vessels allow tumor cells to enter into the circulation system and thus enable them to settle in another organ (tumor metastasis).
In one exemplary embodiment, the neovascularization may be ocular vascularization.
For example, the neovascularization may be found in eye diseases such as AMD, diabetic retinopathy and the like. Particularly, AMD is the most common cause of legal irreversible blindness in older people over the age of 65 in the US, Canada, England, Wales, Scotland and Australia, and about 10% to 15% of the patients show exudative (wet) diseases. The exudative AMD is characterized by neovascularization and disease-causing angiogenesis.
For example, ocular neovascularization may include choroidal neovascularization (CNV), corneal neovascularization and/or rubeosis iridis.
CNV is the vascularization in the choroid layer, and rapidly occurs in people having a defect in the Bruch's membrane, which is the innermost layer of the choroid. In addition, CNV is associated with an excessive amount of vascular endothelial growth factor (VEGF). CNV may cause excessive myopia, malignant myopia, or neovascular degenerative macular degeneration (e.g., wet macular degeneration).
Corneal neovascularization is the growth of new blood vessels from the pericorneal plexus in the periphery of the cornea into avascular corneal tissue due to oxygen deprivation, and may be mainly caused by congenital or inflammatory (e.g., rejection after corneal transplantation, grafted tissue or host diseases, atopic conjunctivitis, injections, ocular pemphigoid, Lyell's syndrome, and Stevens-Johnson syndrome), infectious (e.g., bacterial (chlamydia, syphilis, pseduomonas), viral (herpes simplex virus and herpes zoster virus), fungal (candida, aspergillus, fusarium), parasistic (onchocerca volvolus), degenerative, traumatic and iatrogenic (e.g., the wearing of contact lenses) diseases.
Rubeosis iridis is the vascularization on the surface of the iris, associated with diabetic retinopathy, and also known to be caused by central retinal vein occlusion, ocular ischemic syndrome, chronic retinal detachment, and the like.
In a certain embodiment, the neovascularization may be associated with survival, proliferation, persistency, cytotoxicity, and a cytokine-release function of vascular endothelial cells.
In a certain embodiment, neovascularization may be associated with an increase in the expression of an angiogenic cytokine.
In a certain embodiment, the neovascularization may be associated with functions of a receptor of vascular endothelial cells.
In a certain embodiment, the neovascularization may be associated with a migration ability of vascular endothelial cells.
In a certain embodiment, the neovascularization may be associated with an attachment ability of vascular endothelial cells.

In a certain embodiment, the artificially manipulated neovascularization-associated factor may be genetically manipulated.
The gene manipulation or modification may be achieved by artificial insertion, deletion, substitution or inversion occurring in a partial or entire region of the genomic sequence of a wild type gene. In addition, the gene manipulation or modification may be achieved by fusion of manipulation or modification of two or more genes.
For example, the gene is inactivated by such gene manipulation or modification, such that a protein encoded from the gene may not be expressed in the form of a protein having an innate function.

The manipulation includes all types of structural or functional modifications of the neovascularization-associated factor.
The structural modification of the neovascularization-associated factor includes all types of modifications, which are not the same as those of a wild type existing in a natural state.
For example, when the neovascularization-associated factor is DNA, RNA or a gene, the structural modification may be the loss of one or more nucleotides.

The functional modification may be the enhancement in functionality due to increased expression of the neovascularization-associated factor.
The functional modification may be the degradation in functionality due to decreased expression of the neovascularization-associated factor.
In an exemplary embodiment, the manipulated neovascularization-associated factor may be induced by one or more of the following mutations:

- all or partial deletions of the neovascularization-associated factor, that is, a gene to be manipulated (hereinafter, referred to as a target gene), for example, deletion of 1 bp or longer nucleotides, for example, 1 to 30, 1 to 27, 1 to 25, 1 to 23, 1 to 20, 1 to 15, 1 to 10, 1 to 5, 1 to 3, or 1 nucleotide of the target gene,

Meanwhile, a different embodiment of the present invention relates to an additional system for regulating a third in vivo mechanism, concomitant with various functions of the above-described neovascularization-associated factors whose functions are artificially modified.
In one exemplary embodiment, VEGF may be involved in regulation of the third in vivo mechanism.
Since an increase in vascular permeability by VEGF may be a cause of edema, as well as tumor growth, artificially manipulated VEGF may increase a survival rate in various types of tumors (e.g., brain tumor, uterine cancer, vestibular schwannomas, etc.) or recover hearing loss, for example, by manipulation to inactivate VEGF. In addition, a decrease in vascular permeability by artificially manipulated VEGF may impart therapeutic effects on renal failure, arthritis, psoriasis, coronary disease, etc.
In addition, the artificially manipulated VEGF may impart a therapeutic effect on an autoimmune disease. For example, inflammation-inducing activity may be artificially regulated by VEGF, thereby imparting therapeutic effects on uveitis, rheumatoid arthritis, systemic lupus erythematosus, an inflammatory bowel disease, psoriasis, systemic sclerosis, multiple sclerosis, etc.
In addition, the artificially manipulated VEGF may impart a therapeutic effect on a mental disease. For example, a therapeutic effect on depression may be imparted by artificially regulating the expression of a neurotransmission-associated factor by VEGF.
In another embodiment, the artificially manipulated VEGF may be involved in the regulation of a third in vivo mechanism of HIF. The HIF may be HIF1 or HIF2.
The artificially manipulated HIF may regulate inflammation-inducing activity, thereby imparting therapeutic effects on uveitis, rheumatoid arthritis, systemic lupus erythematosus, an inflammatory bowel disease, psoriasis, systemic sclerosis, multiple sclerosis, etc.
In addition, the artificially manipulated HIF may provide a therapeutic effect on an autoimmune disease.
Likewise, the illustrative factors of the present invention which are artificially manipulated may regulate corresponding mechanisms by targeting the third in vivo function as well as the neovascularization function. One exemplary embodiment of the present invention includes such a neovascularization factor whose function is artificially modified and a method for manufacturing the same, a composition including the same, and uses of the factor and the composition for improving or treating a disease associated with a third function.

In an exemplary embodiment, the neovascularization-regulating system includes a composition for manipulating a neovascularization-associated factor.
The composition for manipulation may be a composition capable of artificially manipulating a neovascularization-associated factor, and preferably, a composition for gene manipulation.
Hereinafter, the composition for gene manipulation will be described.
Composition for Manipulating Neovascularization-Associated Factor
Manipulation or modification of substances involved in the neovascularization-associated factor and the neovascularization system of the present invention is preferably accomplished by genetic manipulation.
In one aspect, composition and method for manipulating a gene by targeting a partial or entire non-coding or coding region of the neovascularization-associated factor may be provided.
In an exemplary embodiment, the composition and method may be used in manipulation or modification of one or more neovascularization regulating genes involved in the formation of a desired neovascularization system. The manipulation or modification may be performed by modification of nucleic acids constituting a gene. As a result of the manipulation, all of knockdown, knockout, and knockin are included.
In an exemplary embodiment, the manipulation may be performed by targeting a promoter region, or a transcription sequence, for example, an intron or exon sequence. A coding sequence, for example, a coding region, specifically, an initial coding region may be targeted for the modification of expression and knockout.
In an exemplary embodiment, the modification of nucleic acids may be substitution, deletion, and/or insertion of one or more nucleotides, for example, 1 to 30 bp, 1 to 27 bp, 1 to 25 bp, 1 to 23 bp, 1 to 20 bp, 1 to 15 bp, 1 to 10 bp, 1 to 5 bp, 1 to 3 bp, or 1 bp nucleotides.

In an exemplary embodiment, the knockdown of a gene may be used to decrease the expression of undesired alleles or transcriptomes.
In an exemplary embodiment, non-coding sequences of a promoter, an enhancer, an intron, a 3′UTR, and/or a polyadenylation signal may be targeted to be used in modifying a neovascularization-associated gene affecting a neovascularization function.
In an exemplary embodiment, the activity of a neovascularization-associated gene may be regulated, for example, activated or inactivated by the modification of nucleic acids of the gene.
In an exemplary embodiment, the modification of nucleic acids of the gene may catalyze cleavage of a single strand or double strands, that is, breaks of nucleic acid strands in a specific region of the target gene by a guide nucleic acid-editor protein complex, resulting in inactivation of the target gene.
In an exemplary embodiment, the nucleic acid strand breaks may be repaired through a mechanism such as homologous recombination or non-homologous end joining (NHEJ).
In this case, when the NHEJ mechanism takes place, a change in DNA sequence is induced at the cleavage site, resulting in inactivation of the gene. The repair by NHEJ may induce substitution, insertion or deletion of a short gene fragment, and may be used in the induction of a corresponding gene knockout.
In another aspect, the present invention provides a composition for manipulating a neovascularization-associated factor.
The composition for manipulation is a composition that is able to artificially manipulate a neovascularization-associated factor, and preferably, a composition for gene manipulation.
The composition may be employed in gene manipulation for one or more neovascularization-associated factors involved in formation of a desired neovascularization-regulating system.
The gene manipulation may be performed in consideration of a gene expression regulating process.
In an exemplary embodiment, it may be performed by selecting a suitable manipulation means for each stage of transcription, RNA processing, RNA transporting, RNA degradation, translation, and protein modification regulating stages.
In an exemplary embodiment, small RNA (sRNA) interferes with mRNA or reduces stability thereof using RNA interference (RNAi) or RNA silencing, and in some cases, breaks up mRNA to interrupt the delivery of protein synthesis information, resulting in regulation of the expression of genetic information.
The gene manipulation may be performed by modification of nucleic acids constituting a neovascularization-associated factor. As manipulation results, all of knockdown, knockout, and knockin are included.
In a certain embodiment, the modification of nucleic acids may be substitution, deletion, and/or insertion of one or more nucleotides, for example, 1 to 30 bp, 1 to 27 bp, 1 to 25 bp, 1 to 23 bp, 1 to 20 bp, 1 to 15 bp, 1 to 10 bp, 1 to 5 bp, 1 to 3 bp, or 1 bp nucleotides.
In a certain embodiment, for knockout of one or more neovascularization-associated factors, elimination of the expression of one or more factors, or one or more knockouts of one or two alleles, the gene may be manipulated such that one or more neovascularization-associated factors contain a deletion or mutation.
In a certain embodiment, knockdown of the neovascularization-associated factor may be used to decrease expression of undesired alleles or transcriptomes.
In a certain embodiment, the modification of nucleic acids may be insertion of one or more nucleic acid fragments or genes. Here, the nucleic acid fragment may be a nucleic acid sequence consisting of one or more nucleotides, and a length of the nucleic acid fragment may be 1 to 40 bp, 1 to 50 bp, 1 to 60 bp, 1 to 70 bp, 1 to 80 bp, 1 to 90 bp, 1 to 100 bp, 1 to 500 bp or 1 to 1000 bp. Here, the inserted gene may be one of the neovascularization-associated factors, or a gene having a different function.
In an exemplary embodiment, the modification of nucleic acids may employ a wild type or variant enzyme which is capable of catalyzing hydrolysis (cleavage) of bonds between nucleic acids in a DNA or RNA molecule, preferably, a DNA molecule. It may also employ a guide nucleic acid-editor protein complex.
For example, the gene may be manipulated using one or more nucleases selected from the group consisting of a meganuclease, a zinc finger nuclease, CRISPR/Cas9 (Cas9 protein), CRISPR-Cpf1 (Cpf1 protein) and a TALE-nuclease, thereby regulating the expression of genetic information.
In a certain embodiment, non-limitedly, the gene manipulation may be mediated by NHEJ or homology-directed repair (HDR) using a guide nucleic acid-editor protein complex, for example, a CRISPR/Cas system.
In this case, when the NHEJ mechanism takes place, a change in DNA sequence may be induced at a cleavage site, thereby inactivating the gene. Repair by NHEJ may induce substitution, insertion or deletion of a short gene fragment, and may be used in the induction of the knockout of a corresponding gene.
In another aspect, the present invention may provide the gene manipulation site.
In an exemplary embodiment, when the gene is modified by NHEJ-mediated modification, the gene manipulation site may be a site in the gene, triggering the decrease or elimination of expression of a neovascularization regulating gene product.
For example, the site may be in an initial coding region,

- a promoter sequence,
- an enhancer sequence,
- a specific intron sequence, or
- a specific exon sequence.

In an exemplary embodiment, the composition for manipulating a neovascularization-associated factor may target a neovascularization-associated factor affecting the regulation of neovascularization, such as a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene, or an ANGPTL4 gene, as a manipulation subject.
Examples of target regions, that is, target sequences for regions in which gene manipulation occurs or which are recognized for gene manipulation are summarized in Table 1, Table 2, Table 3, Table 4 and Table 5.
The target sequence may target one or more genes.
The target sequence may simultaneously target two or more genes. Here, the two or more genes may be homologous genes or heterologous genes.
The gene may contain one or more target sequences.
The gene may be simultaneously targeted at two or more target sequences.
The gene may be changed in the site and number of gene manipulations according to the number of target sequences.

First, there is single-stranded gRNA in which a first strand or a second strand of the double-stranded gRNA is linked by a linker domain, and here, the single-stranded gRNA consists of 5′-[first strand]-[linker domain]-[second strand]-3′.
Specifically, the single-stranded gRNA may consist of 5′-[guide domain]-[first complementary domain]-[linker domain]-[second complementary domain]-[proximal domain]-3′ or 5′-[guide domain]-[first complementary domain]-[linker domain]-[second complementary domain]-[proximal domain]-[tail domain]-3′.
Each domain except the linker domain is the same as the description of each domain of the first and second strands of the double-stranded gRNA.
Linker Domain
In the single-stranded gRNA, the linker domain is a domain connecting a first strand and a second strand, and specifically, is a nucleic acid sequence which connects a first complementary domain with a second complementary domain to produce single-stranded gRNA. Here, the linker domain may be connected with the first complementary domain and the second complementary domain or connect the first complementary domain with the second complementary domain by covalent or non-covalent bonding.

The linker domain is suitable to be used in a single-stranded gRNA molecule, and may be connected with the first strand and the second strand of the double-stranded gRNA, or connect the first strand with the second strand by covalent or non-covalent bonding to be used in production of the single-stranded gRNA. The linker domain may be connected with crRNA and tracrRNA of the double-stranded gRNA, or connect crRNA with tracrRNA by covalent or non-covalent bonding to be used in production of the single-stranded gRNA.
The linker domain may have homology with a natural sequence, for example, a partial sequence of tracrRNA, or may be derived therefrom.

Here, the linker domain may be connected with the first complementary domain and the second complementary domain, or may connect the first and second complementary domains by covalent or non-covalent bonding.
The linker domain may be or include a 1 to 30-base sequence. For example, the linker domain may be or include a 1 to 5, 5 to 10, 10 to 15, 15 to 20, 20 to 25 or 25 to 30-base sequence.
Selectively, a part or all of the base sequence of the guide domain, the first complementary domain, the second complementary domain and the linker domain may have a chemical modification. The chemical modification may be methylation, acetylation, phosphorylation, phosphorothioate linkage, a locked nucleic acid (LNA), 2′-O-methyl 3′phosphorothioate (MS) or 2′-O-methyl 3′thioPACE (MSP), but the present invention is not limited thereto.
Therefore, the single-stranded gRNA may consist of 5′-[second complementary domain]-[first complementary domain]-[guide domain]-3′ or 5′-[second complementary domain]-[linker domain]-[first complementary domain]-[guide domain]-3′ as described above.
In addition, the single-stranded gRNA may selectively include an additional base sequence.
In one exemplary embodiment, the single-stranded gRNA may be 5-(Z)_h-(Q)_m-(N_target)-3′; or 5′-(X)_a-(Z)_h-(X)_b-(Q)_m-(X)_c-(N_target)-3′. In another embodiment, the single-stranded gRNA may be 5′-(Z)_h-(L)_j-(Q)_m-(N_target)-3′; or 5-(X)_a-(Z)_h-(L)_j-(Q)_m-(X)_c-(N_target)-3′.
Here, the N_targetis a base sequence capable of forming a complementary bond with a target sequence on a target gene or nucleic acid, and a base sequence region which may be changed according to a target sequence on a target gene or nucleic acid.
In one exemplary embodiment, Ntarget may be a base sequence capable of forming a complementary bond with a target gene, that is, a target sequence of a neovascularization-associated factor such as a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene or an ANGPTL4 gene.
The (Q)m is a base sequence including the first complementary domain, which is able to form a complementary bond with the second complementary domain of the second strand. The (Q)m may be a sequence having partial or complete homology with the first complementary domain of a species existing in nature, and the base sequence of the first complementary domain may be changed according to the species of origin. The Q may be each independently selected from the group consisting of A, U, C and G, and the m may be the number of bases, which is an integer of 5 to 35.
For example, when the first complementary domain has partial or complete homology with a first complementary domain of Parcubacteria bacterium or a first complementary domain derived therefrom, the (Q)m may be 5′-UUUGUAGAU-3′, or a base sequence having at least 50% or more homology with 5′-UUUGUAGAU-3′.
The (Z)h is a base sequence including a second complementary domain, which is able to form a complementary bond with the first complementary domain of the first strand. The (Z)h may be a sequence having partial or complete homology with the second complementary domain of a species existing in nature, and the base sequence of the second complementary domain may be modified according to the species of origin. The Z may be each independently selected from the group consisting of A, U, C and G, and the h may be the number of bases, which is an integer of 5 to 50.
For example, when the second complementary domain has partial or complete homology with a second complementary domain of Parcubacteria bacterium or a Parcubacteria bacterium-derived second complementary domain, the (Z)h may be 5′-AAAUUUCUACU-3′, or a base sequence having at least 50% or more homology with 5′-AAAUUUCUACU-3′.
In addition, the (L)j is a base sequence including the linker domain, which connects the first complementary domain with the second complementary domain. Here, the L may be each independently selected from the group consisting of A, U, C and G, and the j may be the number of bases, which is an integer of 1 to 30.
In addition, each of the (X)a, (X)b and (X)c is selectively an additional base sequence, where the X may be each independently selected from the group consisting of A, U, C and G, and the a, b and c may be the number of bases, which is 0 or an integer of 1 to 20.

CRISPR Enzyme
The term “CRISPR enzyme” is a main protein component of a CRISPR-Cas system, and forms a complex with gRNA, resulting in the CRISPR-Cas system.
The CRISPR enzyme is a nucleic acid or polypeptide (or a protein) having a sequence encoding the CRISPR enzyme, and representatively, a Type II CRISPR enzyme or Type V CRISPR enzyme is widely used.
The Type II CRISPR enzyme is Cas9, which may be derived from various microorganisms such as Streptococcus pyogenes, Streptococcus thermophilus, Streptococcus sp., Staphylococcus aureus, Nocardiopsis dassonvillei, Streptomyces pristinaespiralis, Streptomyces viridochromogenes, Streptosporangium roseum, AlicyclobacHlus acidocaldarius, Bacillus pseudomycoides, Bacillus selenitireducens, Exiguobacterium sibiricum, Lactobacillus delbrueckii, Lactobacillus salivarius, Microscilla marina, Burkholderiales bacterium, Polaromonas naphthalenivorans, Polaromonas sp., Crocosphaera watsonii, Cyanothece sp., Microcystis aeruginosa, Synechococcus sp., Acetohalobium arabaticum, Ammonifex degensii, Caldicelulosiruptor bescii, Candidatus Desulforudis, Clostridium botulinum, Clostridium difficile, Finegoldia magna, Natranaerobius thermophilus, Pelotomaculum thermopropionicum, Acidithiobacillus caldus, Acidithiobacillus ferrooxidans, Allochromatium vinosum, Marinobacter sp., Nitrosococcus halophilus, Nitrosococcus watsoni, Pseudoalteromonas haloplanktis, Ktedonobacter racemifer, Methanohalobium evestigatum, Anabaena variabilis, Nodularia spumigena, Nostoc sp., Arthrospira maxima, Arthrospira platensis, Arthrospira sp., Lyngbya sp., Microcoleus chthonoplastes, Oscillatoria sp., Petrotoga mobilis, Thermosipho africanus and Acaryochloris marina.
The term “Cas9” is an enzyme which binds to gRNA so as to cleave or modify a target sequence or position on a target gene or nucleic acid, and may consist of an HNH domain capable of cleaving a nucleic acid strand forming a complementary bond with gRNA, an RuvC domain capable of cleaving a nucleic acid strand forming a complementary bond with gRNA, an REC domain recognizing a target and a PI domain recognizing PAM. Hiroshi Nishimasu et al. (2014) Cell 156:935-949 may be referenced for specific structural characteristics of Cas9.
In addition, the Type V CRISPR enzyme may be Cpf1, which may be derived from Streptococcus, Campylobacter, Nitratifractor, Staphylococcus, Parvibaculum, Roseburia, Neisseria, Gluconacetobacter, Azospirillum, Sphaerochaeta, Lactobacillus, Eubacterium, Corynebacter, Carnobacterium, Rhodobacter, Listeria, Paludibacter, Clostridium, Lachnospiraceae, Clostridiaridium, Leptotrichia, Francisella, Legionella, Alicyclobacillus, Methanomethyophilus, Porphyromonas, Prevotella, Bacteroidetes, Helcococcus, Letospira, Desulfovibrio, Desulfonatronum, Opitutaceae, Tuberibacillus, Bacillus, Brevibacillus, Methylobacterium or Acidaminococcus.
The Cpf1 may consist of an RuvC domain similar and corresponding to the RuvC domain of Cas9, an Nuc domain without the HNH domain of Cas9, an REC domain recognizing a target, a WED domain and a PI domain recognizing PAM. For specific structural characteristics of Cpf1, Takashi Yamano et al. (2016) Cell 165:949-962 may be referenced.
The CRISPR enzyme of the Cas9 or Cpf1 protein may be isolated from a microorganism existing in nature or non-naturally produced by a recombinant or synthetic method.
Type II CRISPR Enzyme
The crystal structure of the type II CRISPR enzyme was determined according to studies on two or more types of natural microbial type II CRISPR enzyme molecules (Jinek et al., Science, 343(6176):1247997, 2014) and studies on Streptococcus pyogenes Cas9 (SpCas9) complexed with gRNA (Nishimasu et al., Cell, 156:935-949, 2014; and Anders et al., Nature, 2014, doi: 10.1038/nature13579).
The type II CRISPR enzyme includes two lobes, that is, recognition (REC) and nuclease (NUC) lobes, and each lobe includes several domains.
The REC lobe includes an arginine-rich bridge helix (BH) domain, an REC1 domain and an REC2 domain.
Here, the BH domain is a long α-helix and arginine-rich region, and the REC1 and REC2 domains play an important role in recognizing a double strand formed in gRNA, for example, single-stranded gRNA, double-stranded gRNA or tracrRNA.
The NUC lobe includes an RuvC domain, an HNH domain and a PAM-interaction (PI) domain. Here, the RuvC domain encompasses RuvC-like domains, or the HNH domain is used to include HNH-like domains.
Here, the RuvC domain shares structural similarity with members of the microorganism family existing in nature having the type II CRISPR enzyme, and cleaves a single strand, for example, a non-complementary strand of a target gene or nucleic acid, that is, a strand not forming a complementary bond with gRNA. The RuvC domain is sometimes referred to as an RuvCI domain, RuvCII domain or RuvCIII domain in the art, and generally called an RuvC I, RuvCII or RuvCIII. For example, in the case of SpCas9, the RuvC domain is assembled from each of three divided RuvC domains (RuvC I, RuvCII and RuvCIII) located at the sequences of amino acids 1 to 59, 718 to 769 and 909 to 1098 of SpCas9, respectively.
The HNH domain shares structural similarity with the HNH endonuclease, and cleaves a single strand, for example, a complementary strand of a target nucleic acid molecule, that is, a strand forming a complementary bond with gRNA. The HNH domain is located between RuvC II and III motifs. For example, in the case of SpCas9, the HNH domain is located at amino acid sequence 775 to 908 of SpCas9.
The PI domain recognizes a specific base sequence in a target gene or nucleic acid, that is, a protospacer adjacent motif (PAM) or interacts with PAM. For example, in the case of SpCas9, the PI domain is located at the sequence of amino acids1099 to 1368 of SpCas9.
Here, the PAM may vary according to the origin of the type II CRISPR enzyme. For example, when the CRISPR enzyme is SpCas9, PAM may be 5′-NGG-3′, when the CRISPR enzyme is Streptococcus thermophilus Cas9 (StCas9), PAM may be 5′-NNAGAAW-3′(W=A or T), when the CRISPR enzyme is Neisseria meningitides Cas9 (NmCas9), PAM may be 5′-NNNNGATT-3′, and when the CRISPR enzyme is Campylobacter jejuni Cas9 (CjCas9), PAM may be 5′-NNNVRYAC-3′ (V=G or C or A, R=A or G, Y=C or T), where the N may be A, T, G or C; or A, U, G or C.
Type V CRISPR Enzyme
Type V CRISPR enzyme includes similar RuvC domains corresponding to the RuvC domains of the type II CRISPR enzyme, and may consist of an Nuc domain, instead of the HNH domain of the type II CRISPR enzyme, REC and WED domains, which recognize a target, and a PI domain recognizing PAM. For specific structural characteristics of the type V CRISPR enzyme, Takashi Yamano et al. (2016) Cell 165:949-962 may be referenced.
The type V CRISPR enzyme may interact with gRNA, thereby forming a gRNA-CRISPR enzyme complex, that is, a CRISPR complex, and may allow a guide sequence to approach a target sequence including a PAM sequence in cooperation with gRNA. Here, the ability of the type V CRISPR enzyme for interaction with a target gene or nucleic acid is dependent on the PAM sequence.
The PAM sequence is a sequence present in a target gene or nucleic acid, and may be recognized by the PI domain of the type V CRISPR enzyme. The PAM sequence may vary according to the origin of the type V CRISPR enzyme. That is, there are different PAM sequences which are able to be specifically recognized depending on a species.
In one example, the PAM sequence recognized by Cpf1 may be 5′-TTN-3′ (N is A, T, C or G).
CRISPR Enzyme Activity
A CRISPR enzyme cleaves a double or single strand of a target gene or nucleic acid, and has nuclease activity causing breakage or deletion of the double or single strand. Generally, the wild-type type II CRISPR enzyme or type V CRISPR enzyme cleaves the double strand of the target gene or nucleic acid.
To manipulate or modify the above-described nuclease activity of the CRISPR enzyme, the CRISPR enzyme may be manipulated or modified, such a manipulated or modified CRISPR enzyme may be modified into an incompletely or partially active or inactive enzyme.
Incompletely or Partially Active Enzyme
A CRISPR enzyme modified to change enzyme activity, thereby exhibiting incomplete or partial activity is called a nickase.
The term “nickase” refers to a CRISPR enzyme manipulated or modified to cleave only one strand of the double strand of the target gene or nucleic acid, and the nickase has nuclease activity of cleaving a single strand, for example, a strand that is not complementary or complementary to gRNA of the target gene or nucleic acid. Therefore, to cleave the double strand, nuclease activity of the two nickases is needed.
For example, the nickase may have nuclease activity by the RuvC domain. That is, the nickase may include nuclease activity of the HNH domain, and to this end, the HNH domain may be manipulated or modified.
In one example, provided that the CRISPR enzyme is the type II CRISPR enzyme, when the residue 840 in the amino acid sequence of SpCas9 is mutated from histidine to alanine, the nuclease activity of the HNH domain is inactivated to be used as a nickase. Since the nickase produced thereby has nuclease activity of the RuvC domain, it is able to cleave a strand which does not form a complementary bond with a non-complementary strand of the target gene or nucleic acid, that is, gRNA.
In another exemplary embodiment, when the residue 559 in the amino acid sequence of CjCas9 is mutated from histidine to alanine, the nuclease activity of the HNH domain is inactivated to be used as a nickase. The nickase produced thereby has nuclease activity by the RuvC domain, and thus is able to cleave a non-complementary strand of the target gene or nucleic acid, that is, a strand that does not form a complementary bond with gRNA.
For example, the nickase may have nuclease activity by the HNH domain. That is, the nickase may include the nuclease activity of the RuvC domain, and to this end, the RuvC domain may be manipulated or modified.
In one example, provided that the CRISPR enzyme is the type II CRISPR enzyme, in one exemplary embodiment, when the residue 10 in the amino acid sequence of SpCas9 is mutated from aspartic acid to alanine, the nuclease activity of the RuvC domain is inactivated to be used as a nickase. The nickase produced thereby has the nuclease activity of the HNH domain, and thus is able to cleave a complementary strand of the target gene or nucleic acid, that is, a strand that forms a complementary bond with gRNA.
In another exemplary embodiment, when the residue 8 in the amino acid sequence of CjCas9 is mutated from aspartic acid to alanine, the nuclease activity of the RuvC domain is inactivated to be used as a nickase. The nickase produced thereby has the nuclease activity of the HNH domain, and thus is able to cleave a complementary strand of the target gene or nucleic acid, that is, a strand that forms a complementary bond with gRNA.
Inactive Enzyme
A CRISPR enzyme which is modified to make enzyme activity completely inactive is called an inactive CRISPR enzyme.
The term “inactive CRISPR enzyme” refers to a CRISPR enzyme which is modified not to completely cleave the double strand of the target gene or nucleic acid, and the inactive CRISPR enzyme has nuclease inactivity due to the mutation in the domain with nuclease activity of the wild-type CRISPR enzyme. The inactive CRISPR enzyme may be one in which the nuclease activities of the RuvC domain and the HNH domain are inactivated.
For example, the inactive CRISPR enzyme may be manipulated or modified in the RuvC domain and the HNH domain so as to inactive nuclease activity.
In one example, provided that the CRISPR enzyme is the type II CRISPR enzyme, in one exemplary embodiment, when the residues 10 and 840 in the amino acid sequence of SpCas9 are mutated from aspartic acid and histidine to alanine, respectively, nuclease activities by the RuvC domain and the HNH domain are inactivated, such that the double strand may not cleave completely the double strand of the target gene or nucleic acid.
In another exemplary embodiment, when the residues 8 and 559 in the amino acid sequence of CjCas9 are mutated from aspartic acid and histidine to alanine, the nuclease activities by the RuvC domain and the HNH domain are inactivated, such that the double strand may not cleave completely the double strand of the target gene or nucleic acid.
Other Activities
The CRISPR enzyme may have endonuclease activity, exonuclease activity or helicase activity, that is, an ability to anneal the helix structure of the double-stranded nucleic acid, in addition to the above-described nuclease activity.
In addition, the CRISPR enzyme may be modified to completely, incompletely, or partially activate the endonuclease activity, exonuclease activity or helicase activity.
Targeting of CRISPR Enzyme
The CRISPR enzyme may interact with gRNA, thereby forming a gRNA-CRISPR enzyme complex, that is, a CRISPR complex, and lead a guide sequence to approach a target sequence including a PAM sequence in cooperation with gRNA. Here, the ability of the CRISPR enzyme to interact with the target gene or nucleic acid is dependent on the PAM sequence.
The PAM sequence is a sequence present in the target gene or nucleic acid, which may be recognized by the PI domain of the CRISPR enzyme. The PAM sequence may vary depending on the origin of the CRISPR enzyme. That is, there are various PAM sequences which are able to be specifically recognized according to species.
In one example, provided that the CRISPR enzyme is the type II CRISPR enzyme,

- in the case of SpCas9, the PAM sequence may be 5′-NGG-3′, 5′-NAG-3′ and/or 5′-NGA-3′,
- in the case of StCas9, the PAM sequence may be 5′-NGGNG-3′ and/or 5′-NNAGAAW-3′ (W=A or T),
- in the case of NmCas9, the PAM sequence may be 5′-NNNNGATT-3′ and/or 5′-NNNGCTT-3′,
- in the case of CjCas9, the PAM sequence may be 5′-NNNVRYAC-3′ (V=G, C or A; R=A or G; Y=C or T),
- in the case of Streptococcus mutans Cas9 (SmCas9), the PAM sequence may be 5′-NGG-3′ and/or 5′-NAAR-3′ (R=A or G), and
- in the case of Staphylococcus aureus Cas9 (SaCas9), the PAM sequence may be 5′-NNGRR-3′, 5′-NNGRRT-3′ and/or 5′-NNGRRV-3′ (R=A or G; V=G, C or A).

In another example, provided that the CRISPR enzyme is the type V CRISPR enzyme, in the case of Cpf1, the PAM sequence may be 5′-TTN-3′.
Here, the N may be A, T, G or C; or A, U, G or C.
The CRISPR enzyme capable of recognizing a specific PAM sequence may be manipulated or modified using the PAM sequence capable of being specifically recognized according to species. For example, the PI domain of SpCas9 may be replaced with the PI domain of CjCas9 so as to have the nuclease activity of SpCas9 and recognize a CjCas9-specific PAM sequence, thereby producing SpCas9 recognizing the CjCas9-specific PAM sequence. A specifically recognized PAM sequence may be changed by substitution or replacement of the PI domain.
CRISPR Enzyme Mutant
The CRISPR enzyme may be modified to improve or inhibit various characteristics such as nuclease activity, helicase activity, an ability to interact with gRNA, and an ability to approach the target gene or nucleic acid, for example, PAM recognizing ability of the CRISPR enzyme.
In addition, the CRISPR enzyme mutant may be a CRISPR enzyme which interacts with gRNA to form a gRNA-CRISPR enzyme complex, that is, a CRISPR complex, and is modified or manipulated to improve target specificity, when approaching or localized to the target gene or nucleic acid, such that only a double or single strand of the target gene or nucleic acid is cleaved without cleavage of a double or single strand of a non-target gene or nucleic acid which partially forms a complementary bond with gRNA and a non-target gene or nucleic acid which does not form a complementary bond therewith.
Here, an effect of cleaving the double or single strand of the non-target gene or nucleic acid partially forming a complementary bond with gRNA and the non-target gene or nucleic acid not forming a complementary bond therewith is referred to as an off-target effect, a position or base sequence of the non-target gene or nucleic acid partially forming a complementary bond with gRNA and the non-target gene or nucleic acid not forming a complementary bond therewith is referred to as an off-target. Here, there may be one or more off-targets. One the other hand, the cleavage effect of the double or single strand of the target gene or nucleic acid is referred to as an on-target effect, and a location or target sequence of the target gene or nucleic acid is referred to as an on-target.
The CRISPR enzyme mutant is modified in at least one of the amino acids of a naturally-occurring CRISPR enzyme, and may be modified, for example, improved or inhibited in one or more of the various characteristics such as nuclease activity, helicase activity, an ability to interact with gRNA, an ability to approach the target gene or nucleic acid and target specificity, compared to the unmodified CRISPR enzyme. Here, the modification may be substitution, removal, addition of an amino acid, or a mixture thereof.
In the CRISPR enzyme mutant, the modification may be a modification of one or two or more amino acids located in a region consisting of amino acids having positive charges, present in the naturally-occurring CRISPR enzyme.

In one exemplary embodiment, in the case of SpCas9, when residue 10 of the amino acid sequence of SpCas9 is mutated from aspartic acid to alanine, that is, when mutated to D10A, the nuclease activity of the RuvC domain is inactivated, and thus the SpCas9 may be used as a nickase. The nickase produced thereby may not cleave a non-complementary strand of the target gene or nucleic acid, that is, a strand that does not form a complementary bond with gRNA.
In another exemplary embodiment, in the case of CjCas9, when residue 8 of the amino acid sequence of CjCas9 is mutated from aspartic acid to alanine, that is, when mutated to D8A, the nuclease activity of the RuvC domain is inactivated, and thus the CjCas9 may be used as a nickase.

In addition, the modification may be a modification for completely inactivating the nuclease activity of the CRISPR enzyme, and such a CRISPR enzyme mutant may be an inactive CRISPR enzyme.
Here, the modification may be a modification for inactivating the nuclease activities of the RuvC and HNH domains of the CRISPR enzyme, and such a CRISPR enzyme mutant may does not cleave a double strand of the target gene or nucleic acid.
In one exemplary embodiment, in the case of SpCas9, when the residues 10 and 840 in the amino acid sequence of SpCas9 are mutated from aspartic acid and histidine to alanine, that is, mutated to D10A and H840A, respectively, the nuclease activities of the RuvC domain and the HNH domain are inactivated, the double strand of the target gene or nucleic acid may not be completely cleaved.
In another exemplary embodiment, in the case of CjCas9, when residues 8 and 559 of the amino acid sequence of CjCas9 are mutated from aspartic acid and histidine to alanine, that is, mutated to D8A and H559A, respectively, the nuclease activities by the RuvC and HNH domains are inactivated, and thus the double strand of the target gene or nucleic acid may not be completely cleaved.
In addition, the CRISPR enzyme mutant may further include an optionally functional domain, in addition to the innate characteristics of the CRISPR enzyme, and such a CRISPR enzyme mutant may have an additional characteristic in addition to the innate characteristics.
Here, the functional domain may be a domain having methylase activity, demethylase activity, transcription activation activity, transcription repression activity, transcription release factor activity, histone modification activity, RNA cleavage activity or nucleic acid binding activity, or a tag or reporter gene for isolating and purifying a protein (including a peptide), but the present invention is not limited thereto.
The functional domain, peptide, polypeptide or protein may be a deaminase.
For example, an incomplete or partial CRISPR enzyme may additionally include a cytidine deaminase as a functional domain. In one exemplary embodiment, a cytidine deaminase, for example, apolipoprotein B editing complex 1 (APOBEC1) may be added to SpCas9 nickase, thereby producing a fusion protein. The [SpCas9 nickase]-[APOBEC1] formed thereby may be used in base repair or editing of C into T or U, or G into A.
The tag includes a histidine (His) tag, a V5 tag, a FLAG tag, an influenza hemagglutinin (HA) tag, a Myc tag, a VSV-G tag and a thioredoxin (Trx) tag, and the reporter gene includes glutathione-S-transferase (GST), horseradish peroxidase (HRP), chloramphenicol acetyltransferase (CAT) β-galactosidase, β-glucoronidase, luciferase, autofluorescent proteins including the green fluorescent protein (GFP), HcRed, DsRed, cyan fluorescent protein (CFP), yellow fluorescent protein (YFP) and blue fluorescent protein (BFP), but the present invention is not limited thereto.
In addition, the functional domain may be a nuclear localization sequence or signal (NLS) or a nuclear export sequence or signal (NES).
In one example, the CRISPR enzyme may include one or more NLSs. Here, one or more NLSs may be included at an N-terminus of an CRISPR enzyme or the proximity thereof; a C-terminus of the enzyme or the proximity thereof; or a combination thereof. The NLS may be an NLS sequence derived from the following NLSs, but the present invention is not limited thereto: NLS of a SV40 virus large T-antigen having the amino acid sequence PKKKRKV; NLS from nucleoplasmin (e.g., nucleoplasmin bipartite NLS having the sequence KRPAATKKAGQAKKKK); c-myc NLS having the amino acid sequence PAAKRVKLD or RQRRNELKRSP; hRNPA1 M9 NLS having the sequence NQSSNFGPMKGGNFGGRSSGPYGGGGQYFAKPRNQGGY; the sequence RMRIZFKNKGKDTAELRRRRVEVSVELRKAKKDEQILKRRNV of the IBB domain from importin-α; the sequences VSRKRPRP and PPKKARED of a myoma T protein; the sequence POPKKKPL of human p53; the sequence SALIKKKKKMAP of mouse c-abl IV; the sequences DRLRR and PKQKKRK of influenza virus NS1; the sequence RKLKKKIKKL of a hepatitis delta virus antigen; the sequence REKKKFLKRR of a mouse Mx1 protein; the sequence KRKGDEVDGVDEVAKKKSKK of a human poly (ADP-ribose) polymerase; or the NLS sequence RKCLQAGMNLEARKTKK, derived from a sequence of a steroid hormone receptor (human) glucocorticoid.
In addition, the CRISPR enzyme mutant may include a split-type CRISPR enzyme prepared by dividing the CRISPR enzyme into two or more parts. The term “split” refers to functional or structural division of a protein or random division of a protein into two or more parts.
Here, the split-type CRISPR enzyme may be a completely, incompletely or partially active enzyme or inactive enzyme.
For example, the SpCas9 may be divided into two parts between the residue 656, tyrosine, and the residue 657, threonine, thereby generating split SpCas9.
In addition, the split-type CRISPR enzyme may selectively include an additional domain, peptide, polypeptide or protein for reconstitution.
Here, the “reconstitution” refers to formation of the split-type CRISPR enzyme to be structurally the same or similar to the wild-type CRISPR enzyme.
The additional domain, peptide, polypeptide or protein for reconstitution may be FRB and FKBP dimerization domains; intein; ERT and VPR domains; or domains which form a heterodimer under specific conditions.
For example, the SpCas9 may be divided into two parts between the residue 713, serine, and the residue 714, glycine, thereby generating split SpCas9. The FRB domain may be connected to one of the two parts, and the FKBP domain may be connected to the other one. In the split SpCas9 produced thereby, the FRB domain and the FKBP domain may be formed in a dimer in an environment in which rapamycine is present, thereby producing a reconstituted CRISPR enzyme.
The CRISPR enzyme or CRISPR enzyme mutant described in the present invention may be a polypeptide, protein or nucleic acid having a sequence encoding the same, and may be codon-optimized for a subject to introduce the CRISPR enzyme or CRISPR enzyme mutant.
The term “codon optimization” refers to a process of modifying a nucleic acid sequence by maintaining a native amino acid sequence while replacing at least one codon of the native sequence with a codon more frequently or the most frequently used in host cells so as to improve expression in the host cells. A variety of species have a specific bias to a specific codon of a specific amino acid, and the codon bias (the difference in codon usage between organisms) is frequently correlated with efficiency of the translation of mRNA, which is considered to be dependent on the characteristic of a translated codon and availability of a specific tRNA molecule. The dominance of tRNA selected in cells generally reflects codons most frequently used in peptide synthesis. Therefore, a gene may be customized by optimal gene expression in a given organism based on codon optimization.
3. Target Sequence
The term “target sequence” is a base sequence present in a target gene or nucleic acid, and has complementarity to a guide sequence contained in a guide domain of a guide nucleic acid. The target sequence is a base sequence which may vary according to a target gene or nucleic acid, that is, a subject for gene manipulation or correction, which may be designed in various forms according to the target gene or nucleic acid.
The target sequence may form a complementary bond with the guide sequence contained in the guide domain of the guide nucleic acid, and a length of the target sequence may be the same as that of the guide sequence.

4. Guide Nucleic Acid-Editor Protein Complex and Use Thereof
A guide nucleic acid-editor protein complex may modify a target.
The target may be a target nucleic acid, gene, chromosome or protein.
For example, the guide nucleic acid-editor protein complex may be used to ultimately regulate (e.g., inhibit, suppress, reduce, increase or promote) the expression of a protein of interest, remove a protein, regulate (e.g., inhibit, suppress, reduce, increase or promote) protein activity, or express a new protein.
Here, the guide nucleic acid-editor protein complex may act at a DNA, RNA, gene or chromosomal level.
For example, the guide nucleic acid-editor protein complex may regulate (e.g., inhibit, suppress, reduce, increase or promote) the expression of a protein encoded by target DNA, remove a protein, regulate (e.g., inhibit, suppress, reduce, increase or promote) protein activity, or express a modified protein through manipulation or modification of the target DNA.
In another example, the guide nucleic acid-editor protein complex may regulate (e.g., inhibit, suppress, reduce, increase or promote) the expression of a protein encoded by target DNA, remove a protein, regulate (e.g., inhibit, suppress, reduce, increase or promote) protein activity, or express a modified protein through manipulation or modification of target RNA.
In one example, the guide nucleic acid-editor protein complex may regulate (e.g., inhibit, suppress, reduce, increase or promote) the expression of a protein encoded by target DNA, remove a protein, regulate (e.g., inhibit, suppress, reduce, increase or promote) protein activity, or express a modified protein through manipulation or modification of a target gene.
In another example, the guide nucleic acid-editor protein complex may regulate (e.g., inhibit, suppress, reduce, increase or promote) the expression of a protein encoded by target DNA, remove a protein, regulate (e.g., inhibit, suppress, reduce, increase or promote) protein activity, or express a modified protein through manipulation or modification of a target chromosome.

In another example, the guide nucleic acid-editor protein complex may promote or suppress the translation of a target gene, thereby regulating (e.g., inhibiting, suppressing, reducing, increasing or promoting) the expression of a protein encoded by the target gene.
The guide nucleic acid-editor protein complex may act at a protein level.
In one example, the guide nucleic acid-editor protein complex may manipulate or modify a target protein, thereby removing the target protein or regulating (e.g., inhibiting, suppressing, reducing, increasing or promoting) protein activity.
In one exemplary embodiment, the present invention provides a guide nucleic acid-editor protein complex used to manipulate a neovascularization-associated factor, for example, a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene, and/or an ANGPTL4 gene. Preferably, a gRNA-CRISPR enzyme complex is provided.
Particularly, the present invention may provide gRNA including a guide domain capable of forming a complementary bond with a target sequence from a gene, for example, isolated or non-natural gRNA and DNA encoding the same. The gRNA and the DNA sequence encoding the same may be designed to be able to complementarily bind to a target sequence listed in Table 1, Table 2, Table 3, Table 4 and Table 5.
In addition, a target region of the gRNA is designed to provide a third gene, which has a nucleic acid modification, for example, double or single strand breaks; or a specific function at a target site in a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene, and/or an ANGPTL4 gene.
In addition, when two or more gRNAs are used to induce two or more cleaving events in a target gene, for example, a double or single strand break, the two or more cleaving events may occur due to the same or different Cas9 proteins.
The gRNA may target, for example, two or more of the VEGFA gene, the HIF1A gene, the ANGPT2 gene, the EPAS1 gene, and/or the ANGPTL4 gene, or two or more regions in each of the VEGFA gene, HIF1A gene, ANGPT2 gene, EPAS1 gene, and/or ANGPTL4 gene, and may independently induce the cleavage of a double strand and/or a single strand of the VEGFA gene, HIF1A gene, ANGPT2 gene, EPAS1 gene, and/or ANGPTL4 gene, or may induce the insertion of one foreign nucleotide into a cleavage site of the VEGFA gene, the HIF1A gene, the ANGPT2 gene, the EPAS1 gene, and/or the ANGPTL4 gene.
In addition, in another exemplary embodiment of the present invention, a nucleic acid constituting the guide nucleic acid-editor protein complex may include: (a) a sequence encoding a guide nucleic acid including a guide domain, which is complementary to a target sequence of the VEGFA gene, the HIF1A gene, the ANGPT2 gene, the EPAS1 gene, and/or the ANGPTL4 gene as described herein; and (b) a sequence encoding an editor protein.
Here, there may be two or more of the (a) according to a target region, and the (b) may employ the same or two or more editor proteins.
In an embodiment, the nucleic acid may be designed to target an enzymatically inactive editor protein or a fusion protein (e.g., a transcription repressor domain fusion) thereof to place it sufficiently adjacent to a knockdown target site in order to reduce, decrease or inhibit expression of the VEGFA gene, the HIF1A gene, the ANGPT2 gene, the EPAS1 gene, and/or the ANGPTL4 gene.
Besides, it should be obvious that the above-described structure, function, and all applications of the guide nucleic acid-editor protein complex will be utilized in manipulation of the VEGFA gene, the HIF1A gene, the ANGPT2 gene, the EPAS1 gene, and/or the ANGPTL4 gene.
Use of Guide Nucleic Acid-Editor Protein Complex
In an embodiment for the use of the guide nucleic acid-editor protein complex of the present invention, the manipulation or modification of target DNA, RNA, genes or chromosomes using the gRNA-CRISPR enzyme complex will be described below.
Gene Manipulation
A target gene or nucleic acid may be manipulated or corrected using the above-described gRNA-CRISPR enzyme complex, that is, the CRISPR complex. Here, the manipulation or correction of the target gene or nucleic acid includes all of the stages of i) cleaving or damaging the target gene or nucleic acid and ii) repairing the damaged target gene or nucleic acid.
i) Cleavage or Damage of Target Gene or Nucleic Acid
i) The cleavage or damage of the target gene or nucleic acid may be cleavage or damage of the target gene or nucleic acid using the CRISPR complex, and particularly, cleavage or damage of a target sequence in the target gene or nucleic acid.
In one example, the cleavage or damage of the target gene or nucleic acid using the CRISPR complex may be complete cleavage or damage to the double strand of a target sequence.

In another exemplary embodiment, when SpCas9 nickase (D10A) and SpCas9 nickase (H840A) are used, a complementary single strand of a target sequence forming a complementary bond with gRNA may be cleaved by the SpCas9 nickase (D10A), and a non-complementary single strand of the target sequence forming a complementary bond with gRNA may be cleaved by the SpCas9 nickase (H840A), and the cleavages may take place sequentially or simultaneously.
In still another exemplary embodiment, when SpCas9 nickase (D10A) and SpCas9 nickase (H840A), and two gRNAs having different target sequences are used, a complementary single strand of a target sequence forming a complementary bond with the first gRNA may be cleaved by the SpCas9 nickase (D10A), a non-complementary single strand of a target sequence forming a complementary bond with the second gRNA may be cleaved by the SpCas9 nickase (H840A), and the cleavages may take place sequentially or simultaneously.
In another example, the cleavage or damage of a target gene or nucleic acid using the CRISPR complex may be cleavage or damage to only the single strand of a target sequence. Here, the single strand may be a complementary single strand of a target sequence forming a complementary bond with gRNA, or a non-complementary single strand of the target sequence forming a complementary bond with gRNA.
In one exemplary embodiment, when SpCas9 nickase (D10A) is used, a complementary single strand of a target sequence forming a complementary bond with gRNA may be cleaved by the SpCas9 nickase (D10A), but a non-complementary single strand of the target sequence forming a complementary bond with gRNA may not be cleaved.
In another exemplary embodiment, when SpCas9 nickase (H840A) is used, a complementary single strand of a target sequence forming a complementary bond with gRNA may be cleaved by the SpCas9 nickase (H840A), but a non-complementary single strand of the target sequence forming a complementary bond with gRNA may not be cleaved.
In yet another example, the cleavage or damage of a target gene or nucleic acid using the CRISPR complex may be partial removal of a nucleic acid fragment.
In one exemplary embodiment, when two gRNAs having different target sequences and wild-type SpCas9 are used, a double strand of a target sequence forming a complementary bond with the first gRNA may be cleaved, and a double strand of a target sequence forming a complementary bond with the second gRNA may be cleaved, resulting in the removal of nucleic acid fragments by the first and second gRNAs and SpCas9.
In another exemplary embodiment, when two gRNAs having different target sequences, wild-type SpCas9, SpCas9 nickase (D10A) and SpCas9 nickase (H840A) are used, a double strand of a target sequence forming a complementary bond with the first gRNA may be cleaved by the wild-type SpCas9, a complementary single strand of a target sequence forming a complementary bond with the second gRNA may be cleaved by the SpCas9 nickase (D10A), and a non-complementary single strand nay be cleaved by the SpCas9 nickase (H840A), resulting in the removal of nucleic acid fragments by the first and second gRNAs, the wild-type SpCas9, the SpCas9 nickase (D10A) and the SpCas9 nickase (H840A).
In still another exemplary embodiment, when two gRNAs having different target sequences, SpCas9 nickase (D10A) and SpCas9 nickase (H840A) are used, a complementary single strand of a target sequence forming a complementary bond with the first gRNA may be cleaved by the SpCas9 nickase (D10A), a non-complementary single strand may be cleaved by the SpCas9 nickase (H840A), a complementary double strand of a target sequence forming a complementary bond with the second gRNA may be cleaved by the SpCas9 nickase (D10A), and a non-complementary single strand may be cleaved by the SpCas9 nickase (H840A), resulting in the removal of nucleic acid fragments by the first and second gRNAs, the SpCas9 nickase (D10A) and the SpCas9 nickase (H840A).
In yet another exemplary embodiment, when three gRNAs having different target sequences, wild-type SpCas9, SpCas9 nickase (D10A) and SpCas9 nickase (H840A) are used, a double strand of a target sequence forming a complementary bond with the first gRNA may be cleaved by the wild-type SpCas9, a complementary single strand of a target sequence forming a complementary bond with the second gRNA may be cleaved by the SpCas9 nickase (D10A), and a non-complementary single strand of a target sequence forming a complementary bond with the third gRNA may be cleaved by the SpCas9 nickase (H840A), resulting in the removal of nucleic acid fragments by the first gRNA, the second gRNA, the third gRNA, the wild-type SpCas9, the SpCas9 nickase (D10A) and the SpCas9 nickase (H840A).
In yet another exemplary embodiment, when four gRNAs having different target sequences, SpCas9 nickase (D10A) and SpCas9 nickase (H840A) are used, a complementary single strand of a target sequence forming a complementary bond with the first gRNA may be cleaved by the SpCas9 nickase (D10A), a non-complementary single strand of a target sequence forming a complementary bond with the second gRNA may be cleaved by the SpCas9 nickase (H840A), a complementary single strand of a target sequence forming a complementary bond with the third gRNA may be cleaved by the SpCas9 nickase (D10A), and a non-complementary single strand of a target sequence forming a complementary bond with fourth gRNA may be cleaved by the SpCas9 nickase (H840A), resulting in the removal of nucleic acid fragments by the first gRNA, the second gRNA, the third gRNA, the fourth gRNA, the SpCas9 nickase (D10A) and the SpCas9 nickase (H840A).
ii) Repair or Restoration of Damaged Target Gene or Nucleic Acid
The target gene or nucleic acid cleaved or damaged by the CRISPR complex may be repaired or restored through NHEJ and homology-directed repairing (HDR).
Non-Homologous End Joining (NHEJ)
NHEJ is a method of restoration or repairing double strand breaks in DNA by joining both ends of a cleaved double or single strand together, and generally, when two compatible ends formed by breaking of the double strand (for example, cleavage) are frequently in contact with each other to completely join the two ends, the broken double strand is recovered. The NHEJ is a restoration method that is able to be used in the entire cell cycle, and usually occurs when there is no homologous genome to be used as a template in cells, like the G1 phase.
In the repair process of the damaged gene or nucleic acid using NHEJ, some insertions and/or deletions (indels) in the nucleic acid sequence occur in the NHEJ-repaired region, such insertions and/or deletions cause the leading frame to be shifted, resulting in frame-shifted transcriptome mRNA. As a result, innate functions are lost because of nonsense-mediated decay or the failure to synthesize normal proteins. In addition, while the leading frame is maintained, mutations in which insertion or deletion of a considerable amount of sequence may be caused to destroy the functionality of the proteins. The mutation is locus-dependent because mutations in a significant functional domain is probably less tolerated than mutations in a non-significant region of a protein.
While it is impossible to expect indel mutations produced by NHEJ in a natural state, a specific indel sequence is preferred in a given broken region, and can come from a small region of micro homology. Conventionally, the deletion length ranges from 1 bp to 50 bp, insertions tend to be shorter, and frequently include a short repeat sequence directly surrounding a broken region.
In addition, the NHEJ is a process causing a mutation, and when it is not necessary to produce a specific final sequence, may be used to delete a motif of the small sequence.
A specific knockout of a gene targeted by the CRISPR complex may be performed using such NHEJ. A double strand or two single strands of a target gene or nucleic acid may be cleaved using the CRISPR enzyme such as Cas9 or Cpf1, and the broken double strand or two single strands of the target gene or nucleic acid may have indels through the NHEJ, thereby inducing specific knockout of the target gene or nucleic acid. Here, the site of a target gene or nucleic acid cleaved by the CRISPR enzyme may be a non-coding or coding region, and in addition, the site of the target gene or nucleic acid restored by NHEJ may be a non-coding or coding region.
Homology Directed Repairing (HDR)
HDR is a correction method without an error, which uses a homologous sequence as a template to repair or restoration a damaged gene or nucleic acid, and generally, to repair or restoration broken DNA, that is, to restore innate information of cells, the broken DNA is repaired using information of a complementary base sequence which is not modified or information of a sister chromatid. The most common type of HDR is homologous recombination (HR). HDR is a repair or restoration method usually occurring in the S or G2/M phase of actively dividing cells.
To repair or restore damaged DNA using HDR, rather than using a complementary base sequence or sister chromatin of the cells, a DNA template artificially synthesized using information of a complementary base sequence or homologous base sequence, that is, a nucleic acid template including a complementary base sequence or homologous base sequence may be provided to the cells, thereby repairing the broken DNA. Here, when a nucleic acid sequence or nucleic acid fragment is further added to the nucleic acid template to repair the broken DNA, the nucleic acid sequence or nucleic acid fragment further added to the broken DNA may be subjected to knockin. The further added nucleic acid sequence or nucleic acid fragment may be a nucleic acid sequence or nucleic acid fragment for correcting the target gene or nucleic acid modified by a mutation to a normal gene or nucleic acid, or a gene or nucleic acid to be expressed in cells, but the present invention is not limited thereto.
In one example, a double or single strand of a target gene or nucleic acid may be cleaved using the CRISPR complex, a nucleic acid template including a base sequence complementary to a base sequence adjacent to the cleavage site may be provided to cells, and the cleaved base sequence of the target gene or nucleic acid may be repaired or restored through HDR.
Here, the nucleic acid template including the complementary base sequence may have broken DNA, that is, a cleaved double or single strand of a complementary base sequence, and further include a nucleic acid sequence or nucleic acid fragment to be inserted into the broken DNA. An additional nucleic acid sequence or nucleic acid fragment may be inserted into a cleaved site of the broken DNA, that is, the target gene or nucleic acid using the nucleic acid template including a nucleic acid sequence or nucleic acid fragment to be inserted into the complementary base sequence. Here, the nucleic acid sequence or nucleic acid fragment to be inserted and the additional nucleic acid sequence or nucleic acid fragment may be a nucleic acid sequence or nucleic acid fragment for correcting a target gene or nucleic acid modified by a mutation to a normal gene or nucleic acid or a gene or nucleic acid to be expressed in cells. The complementary base sequence may be a base sequence having complementary bonds with broken DNA, that is, right and left base sequences of the cleaved double or single strand of the target gene or nucleic acid. Alternatively, the complementary base sequence may be a base sequence having complementary bonds with broken DNA, that is, 3′ and 5′ ends of the cleaved double or single strand of the target gene or nucleic acid. The complementary base sequence may be a 15 to 3000-base sequence, a length or size of the complementary base sequence may be suitably designed according to a size of the nucleic acid template or the target gene. Here, as the nucleic acid template, a double- or single-stranded nucleic acid may be used, or it may be linear or circular, but the present invention is not limited thereto.
In another example, a double- or single-stranded target gene or nucleic acid is cleaved using the CRISPR complex, a nucleic acid template including a homologous base sequence with a base sequence adjacent to a cleavage site is provided to cells, and the cleaved base sequence of the target gene or nucleic acid may be repaired or restored by HDR.
Here, the nucleic acid template including the homologous base sequence may be broken DNA, that is, a cleaved double- or single-stranded homologous base sequence, and further include a nucleic acid sequence or nucleic acid fragment to be inserted into the broken DNA. An additional nucleic acid sequence or nucleic acid fragment may be inserted into broken DNA, that is, a cleaved site of a target gene or nucleic acid using the nucleic acid template including a homologous base sequence and a nucleic acid sequence or nucleic acid fragment to be inserted. Here, the nucleic acid sequence or nucleic acid fragment to be inserted and the additional nucleic acid sequence or nucleic acid fragment may be a nucleic acid sequence or nucleic acid fragment for correcting a target gene or nucleic acid modified by a mutation to a normal gene or nucleic acid or a gene or nucleic acid to be expressed in cells. The homologous base sequence may be broken DNA, that is, a base sequence having homology with cleaved double-stranded base sequence or right and left single-stranded base sequences of a target gene or nucleic acid. Alternatively, the complementary base sequence may be a base sequence having homology with broken DNA, that is, the 3′ and 5′ ends of a cleaved double or single strand of a target gene or nucleic acid. The homologous base sequence may be a 15 to 3000-base sequence, and a length or size of the homologous base sequence may be suitably designed according to a size of the nucleic acid template or a target gene or nucleic acid. Here, as the nucleic acid template, a double- or single-stranded nucleic acid may be used and may be linear or circular, but the present invention is not limited thereto.
Other than the NHEJ and HDR, there are methods of repairing or restoring broken DNA.
Single-Strand Annealing (SSA)
SSA is a method of repairing double strand breaks between two repeat sequences present in a target nucleic acid, and generally uses a repeat sequence of more than 30 bases. The repeat sequence is cleaved (to have sticky ends) to have a single strand with respect to a double strand of the target nucleic acid at each of the broken ends, and after the cleavage, a single-strand overhang containing the repeat sequence is coated with an RPA protein such that it is prevented from inappropriately annealing the repeat sequences to each other. RAD52 binds to each repeat sequence on the overhang, and a sequence capable of annealing a complementary repeat sequence is arranged. After annealing, a single-stranded flap of the overhang is cleaved, and synthesis of new DNA fills a certain gap to restore a DNA double strand. As a result of this repair, a DNA sequence between two repeats is deleted, and a deletion length may be dependent on various factors including the locations of the two repeats used herein, and a path or degree of the progress of cleavage.
SSA, similar to HDR, utilizes a complementary sequence, that is, a complementary repeat sequence, and in contrast, does not requires a nucleic acid template for modifying or correcting a target nucleic acid sequence.
Single-Strand Break Repair (SSBA)
Single strand breaks in a genome are repaired through a separate mechanism, SSBR, from the above-described repair mechanisms. In the case of single-strand DNA breaks, PARP1 and/or PARP2 recognizes the breaks and recruits a repair mechanism. PARP1 binding and activity with respect to the DNA breaks are temporary, and SSBR is promoted by promoting the stability of an SSBR protein complex in the damaged regions. The most important protein in the SSBR complex is XRCC1, which interacts with a protein promoting 3′ and 5′ end processing of DNA to stabilize the DNA. End processing is generally involved in repairing the damaged 3′ end to a hydroxylated state, and/or the damaged 5′ end to a phosphatic moiety, and after the ends are processed, DNA gap filling takes place. There are two methods for the DNA gap filling, that is, short patch repair and long patch repair, and the short patch repair involves insertion of a single base. After DNA gap filling, a DNA ligase promotes end joining.
Mismatch Repair (MMR)
MMR works on mismatched DNA bases. Each of an MSH2/6 or MSH2/3 complex has ATPase activity and thus plays an important role in recognizing a mismatch and initiating a repair, and the MSH2/6 primarily recognizes base-base mismatches and identifies one or two base mismatches, but the MSH2/3 primarily recognizes a larger mismatch.
Base Excision Repair (BER)
BER is a repair method which is active throughout the entire cell cycle, and used to remove a small non-helix-distorting base damaged region from the genome. In the damaged DNA, damaged bases are removed by cleaving an N-glycoside bond joining a base to the phosphate-deoxyribose backbone, and then the phosphodiester backbone is cleaved, thereby generating breaks in single-strand DNA. The broken single strand ends formed thereby were removed, a gap generated due to the removed single strand is filled with a new complementary base, and then an end of the newly-filled complementary base is ligated with the backbone by a DNA ligase, resulting in repair of the damaged DNA.
Nucleotide Excision Repair (NER)
NER is an excision mechanism important for removing large helix-distorting damage from DNA, and when the damage is recognized, a short single-strand DNA segment containing the damaged region is removed, resulting in a single strand gap of 22 to 30 bases. The generated gap is filled with a new complementary base, and an end of the newly filled complementary base is ligated with the backbone by a DNA ligase, resulting in the repair of the damaged DNA.
Gene Manipulation Effects
Manipulation or correction of a target gene or nucleic acid may largely lead to effects of knockout, knockdown, and knockin.
Knockout
The term “knockout” refers to inactivation of a target gene or nucleic acid, and the “inactivation of a target gene or nucleic acid” refers to a state in which transcription and/or translation of a target gene or nucleic acid does not occur. Transcription and translation of a gene causing a disease or a gene having an abnormal function may be inhibited through knockout, resulting in the prevention of protein expression.
For example, when a target gene or nucleic acid is edited or corrected using a gRNA-CRISPR enzyme complex, that is, a CRISPR complex, the target gene or nucleic acid may be cleaved using the CRISPR complex. The damaged target gene or nucleic acid may be repaired through NHEJ using the CRISPR complex. The damaged target gene or nucleic acid may have indels due to NHEJ, and thereby, specific knockout for the target gene or nucleic acid may be induced.
Knockdown
The term “knockdown” refers to a decrease in transcription and/or translation of a target gene or nucleic acid or the expression of a target protein. The onset of a disease may be prevented or a disease may be treated by regulating the overexpression of a gene or protein through the knockdown.
For example, when a target gene or nucleic acid is edited or corrected using a gRNA-CRISPR inactive enzyme-transcription inhibitory activity domain complex, that is, a CRISPR inactive complex including a transcription inhibitory activity domain, the CRISPR inactive complex may specifically bind to the target gene or nucleic acid, transcription of the target gene or nucleic acid may be inhibited by the transcription inhibitory activity domain included in the CRISPR inactive complex, thereby inducing knockdown in which expression of the corresponding gene or nucleic acid is inhibited.
Knockin
The term “knockin” refers to insertion of a specific nucleic acid or gene into a target gene or nucleic acid, and here, the “specific nucleic acid” refers to a gene or nucleic acid of interest to be inserted or expressed. A mutant gene triggering a disease may be utilized in disease treatment by correction to normal or insertion of a normal gene to induce expression of the normal gene through the knockin.
In addition, the knockin may further need a donor.
For example, when a target gene or nucleic acid is edited or corrected using a gRNA-CRISPR enzyme complex, that is, a CRISPR complex, the target gene or nucleic acid may be cleaved using the CRISPR complex. The target gene or nucleic acid damaged using the CRISPR complex may be repaired through HDR. Here, a specific nucleic acid may be inserted into the damaged gene or nucleic acid using a donor.
The term “donor” refers to a nucleic acid sequence that helps HDR-based repair of the damaged gene or nucleic acid, and here, the donor may include a specific nucleic acid.
The donor may be a double- or single-stranded nucleic acid.
The donor may be present in a linear or circular shape.
The donor may include a nucleic acid sequence having homology with a target gene or nucleic acid.
For example, the donor may include a nucleic acid sequence having homology with each of base sequences at a location into which a specific nucleic acid is to be inserted, for example, upstream (left) and downstream (right) of a damaged nucleic acid. Here, the specific nucleic acid to be inserted may be located between a nucleic acid sequence having homology with a base sequence downstream of the damaged nucleic acid and a nucleic acid sequence having homology with a base sequence upstream of the damaged nucleic acid. Here, the homologous nucleic acid sequence may have at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95% or more homology or complete homology.
The donor may optionally include an additional nucleic acid sequence. Here, the additional nucleic acid sequence may serve to increase donor stability, knockin efficiency or HDR efficiency.
For example, the additional nucleic acid sequence may be an A, T-rich nucleic acid sequence, that is, an A-T rich domain. In addition, the additional nucleic acid sequence may be a scaffold/matrix attachment region (SMAR).
In one exemplary embodiment relating to a gene manipulation effect of the present invention, a manipulated target gene obtained using a gRNA-CRISPR enzyme complex, that is, a manipulated neovascularization-associated factor may have the following constitution.
In one exemplary embodiment, when the neovascularization-associated factor is a gene, the constitution of the artificially manipulated neovascularization-associated factor by the gRNA-CRISPR enzyme complex may include modification of one or more nucleic acids among a deletion or insertion of one or more nucleotides; a substitution with one or more nucleotides different from a wild-type gene; and an insertion of one or more foreign nucleotides in a continuous 1 bp to 50 bp, 1 bp to 40 bp or 1 bp to 30 bp, preferably, 3 bp to 25 bp region in the base sequence, which is located in a PAM sequence in a nucleic acid sequence constituting the neovascularization-associated factor or adjacent to a 5′ end and/or 3′ end thereof.
In addition, a chemical modification of one or more nucleotides may be included in the nucleic acid sequence constituting the neovascularization-associated factor.
Here, the “foreign nucleotide” is the concept including all exogeneous, for example, heterologous or artificially-synthesized nucleotides, other than nucleotides innately included in the neovascularization-associated factor. The foreign nucleotide also includes a nucleotide with a size of several hundred, thousand or tens of thousands of bp to express a protein having a specific function, as well as a small ologonucleotide with a size of 50 bp or less. Such a foreign nucleotide may be a donor.
The chemical modification may include methylation, acetylation, phosphorylation, ubiquitination, ADP-ribosylation, myristylation, and glycosylation, for example, substitution of some functional groups contained in a nucleotide with any one of a hydrogen atom, a fluorine atom, an —O-alkyl group, an —O-acyl group, and an amino group, but the present invention is not limited thereto. In addition, to increase transferability of a nucleic acid molecule, the functional groups may also be substituted with any one of —Br, —Cl, —R, —R′OR, —SH, —SR, —N3 and —CN (R=alkyl, aryl, alkylene). In addition, the phosphate backbone of at least one nucleotide may be substituted with any one of an alkylphosphonate form, a phosphoroamidate form and a boranophosphate form. In addition, the chemical modification may be a substitution of at least one type of nucleotide contained in the nucleic acid molecule with any one of a locked nucleic acid (LNA), an unlocked nucleic acid (UNA), a morpholino, and a peptide nucleic acid (PNA), and the chemical modification may be bonding of the nucleic acid molecule with one or more selected from the group consisting of a lipid, a cell-penetrating peptide and a cell-target ligand.
To form a desired neovascularization regulating system, artificial modification using a gRNA-CRISPR enzyme complex may be applied to the nucleic acid constituting the neovascularization-associated factor.
A region including the nucleic acid modification of the neovascularization-associated factor may be a target region or target sequence.
Such a target sequence may be a target for the gRNA-CRISPR enzyme complex, and the target sequence may include or not include a PAM sequence recognized by the CRISPR enzyme. Such a target sequence may provide a critical standard in a gRNA designing stage to those of ordinary skill in the art.
Such nucleic acid modification includes the “cleavage” of a nucleic acid.
The term “cleavage” in a target region refers to breakage of a covalent backbone of polynucleotides. The cleavage includes enzymatic or chemical hydrolysis of a phosphodiester bond, but the present invention is not limited thereto, and also include various other methods. The cleavage is able to be performed on both of a single strand and a double strand, and the cleavage of a double strand may result from distinct single-strand cleavage. The double-strand cleavage may generate blunt ends or staggered ends.
When an inactivated CRISPR enzyme is used, it may induce a factor possessing a specific function to approach a certain region of the target region or neovascularization-associated factor without the cleavage process. Chemical modification of one or more nucleotides in the nucleic acid sequence of the neovascularization-associated factor may be included according to such a specific function.
In one example, various indels may occur due to target and non-target activities through the nucleic acid cleavage formed by the gRNA-CRISPR enzyme complex.
The term “indel” is the generic term for an insertion or deletion mutation occurring in-between some bases in a DNA base sequence. The indel may be introduced into a target sequence during repair by an HDR or NHEJ mechanism when the gRNA-CRISPR enzyme complex cleaves the nucleic acid (DNA or RNA) of the neovascularization-associated factor as described above.
The artificially manipulated neovascularization-associated factor of the present invention refers to modification of the nucleic acid sequence of an original gene by cleavage, indels, or insertion using a donor of such a nucleic acid, and contributes to a desired neovascularization regulating system, for example, exhibition of an effect of promoting or suppressing neovascularization.
For example, a specific protein may be expressed and its activity may be stimulated by the artificially manipulated neovascularization-associated factor.
A specific protein may be inactivated by the artificially manipulated neovascularization-associated factor.
In one example, a specific target region of each neovascularization-associated factor of the genome, for example, reverse regulatory genes such as a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene, and/or an ANGPTL4 gene may be cleaved, resulting in knockdown or knockout of the gene.
In another example, targeted knockdown may be mediated using an enzymatically inactive CRISPR enzyme fused to a transcription repressor domain or chromatin-modified protein to change transcription, for example, to block, negatively regulate or decrease the transcription of a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene, and/or an ANGPTL4 gene.
The neovascularization may be regulated by the artificially manipulated neovascularization-associated factor.
A neovascularization-associated disease may be improved or treated by the artificially manipulated neovascularization-associated factor.
In one exemplary embodiment of the present invention, the artificially manipulated neovascularization-associated factor may provide various artificially manipulated neovascularization-associated factors according to the constitutional characteristic of the gRNA-CRISPR enzyme complex (e.g., included in a target region of the neovascularization-associated factor or different in the adjacent major PAM sequence).
Hereinafter, while representative examples of CRISPR enzymes and a neovascularization-regulatory gene have been illustrated, they are merely specific examples, and thus the present invention is not limited thereto.
For example, when the CRISPR enzyme is a SpCas9 protein, the PAM sequence is 5′-NGG-3′ (N is A, T, G, or C), and the cleaved base sequence region (target region) may be a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp or 21 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NGG-3′ sequence in a target gene.
The present invention may provide an artificially manipulated neovascularization-associated factor, for example, an artificially manipulated VEGFA gene, HIF1A gene, ANGPT2 gene, EPAS1 gene, and/or ANGPTL4 gene, which is prepared by

- a) deletion of one or more nucleotides of a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NGG-3′ (N is A, T, C or G) sequence,
- b) substitution of one or more nucleotides of a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NGG-3′ sequence with nucleotides different from those of the wild-type gene,
- c) insertion of one or more nucleotides into a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NGG-3′ sequence, or
- d) a combination of two or more selected from a) through c)
- in the nucleic acid sequence of the neovascularization-associated factor.

For example, when the CRISPR enzyme is a CjCas9 protein, the PAM sequence is 5′-NNNNRYAC-3′ (each N is independently A, T, C or G, R is A or G, and Y is C or T), and the cleaved base sequence region (target region) may be a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp or 21 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNNNRYAC-3′ sequence in a target gene.
The present invention may provide an artificially manipulated neovascularization-associated factor, for example, an artificially manipulated VEGFA gene, HIF1A gene, ANGPT2 gene, EPAS1 gene, and/or ANGPTL4 gene, which is prepared by

- a′) deletion of one or more nucleotides of a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNNNRYAC-3′ (each N is independently A, T, C or G, R is A or G, and Y is C or T),
- b′) substitution of one or more nucleotides of a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNNNRYAC-3′ sequence with nucleotides different from those of the wild-type gene,
- c′) insertion of one or more nucleotides into a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNNNRYAC-3′ sequence, or
- d′) a combination of two or more selected from a′) through c′) in the nucleic acid sequence of the neovascularization-associated factor.

For example, when the CRISPR enzyme is a StCas9 protein, the PAM sequence is 5′-NNAGAAW-3′ (each N is independently A, T, C or G, and W is A or T), and the cleaved base sequence region (target region) may be a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp or 21 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNAGAAW-3′ sequence in a target gene.
The present invention may provide an artificially manipulated neovascularization-associated factor, for example, an artificially manipulated VEGFA gene, HIF1A gene, ANGPT2 gene, EPAS1 gene, and/or ANGPTL4 gene, which is prepared by

- a″) deletion of one or more nucleotides of a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNAGAAW-3′ sequence (each N is independently A, T, C or G, and W is A or T),
- b″) substitution of one or more nucleotides of a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNAGAAW-3′ sequence with nucleotides different from those of the wild-type gene,
- c″) insertion of one or more nucleotides into a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNAGAAW-3′ sequence, or
- d″) a combination of two or more selected from a″) through c″) in the nucleic acid sequence of the neovascularization-associated factor.

For example, when the CRISPR enzyme is an NmCas9 protein, the PAM sequence is 5′-NNNNGATT-3′(each N is independently A, T, C or G), and the cleaved base sequence region (target region) may be a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp or 21 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or 3′ end of the 5′-NNNNGATT-3′ sequence in a target gene.
The present invention may provide an artificially manipulated neovascularization-associated factor, for example, an artificially manipulated VEGFA gene, HIF1A gene, ANGPT2 gene, EPAS1 gene, and/or ANGPTL4 gene, which is prepared by

- a′″) deletion of one or more nucleotides of a continuous 1 bp to 25 bp, for example, 17 bp to 23 bp, region in the base sequence adjacent to the 5′ end and/or the 3′ end of the 5′-NNNNGATT-3′ sequence (each N is independently A, T, C or G),

5. Other Additional Components
An additional component may be selectively added to increase the efficiency of a guide nucleic acid-editor protein complex or improve the repair efficiency of a damaged gene or nucleic acid.
The additional component may be selectively used to improve the efficiency of the guide nucleic acid-editor protein complex.
Activator
The additional component may be used as an activator to increase the cleavage efficiency of a target nucleic acid, gene or chromosome of the guide nucleic acid-editor protein complex.
The term “activator” refers to a nucleic acid serving to stabilize the bonding between the guide nucleic acid-editor protein complex and the target nucleic acid, gene or chromosome, or to allow the guide nucleic acid-editor protein complex to more easily approach the target nucleic acid, gene or chromosome.
The activator may be a double-stranded nucleic acid or single-stranded nucleic acid.
The activator may be linear or circular.
The activator may be divided into a “helper” that stabilizes the bonding between the guide nucleic acid-editor protein complex and the target nucleic acid, gene or chromosome, and an “escorter” that serves to allow the guide nucleic acid-editor protein complex to more easily approach the target nucleic acid, gene or chromosome.
The helper may increase the cleavage efficiency of the guide nucleic acid-editor protein complex with respect to the target nucleic acid, gene or chromosome.
For example, the helper includes a nucleic acid sequence having homology with the target nucleic acid, gene or chromosome. Therefore, when the guide nucleic acid-editor protein complex is bonded to the target nucleic acid, gene or chromosome, the homologous nucleic acid sequence included in the helper may form an additional complementary bond with the target nucleic acid, gene or chromosome to stabilize the bonding between the guide nucleic acid-editor protein complex and the target nucleic acid, gene or chromosome.
The escorter may increase the cleavage efficiency of the guide nucleic acid-editor protein complex with respect to the target nucleic acid, gene or chromosome.
For example, the escorter includes a nucleic acid sequence having homology with the target nucleic acid, gene or chromosome. Here, the homologous nucleic acid sequence included in the escorter may partly form a complementary bond with a guide nucleic acid of the guide nucleic acid-editor protein complex. Therefore, the escorter partly forming a complementary bond with the guide nucleic acid-editor protein complex may partly form a complementary bond with the target nucleic acid, gene or chromosome, and as a result, may allow the guide nucleic acid-editor protein complex to accurately approach the position of the target nucleic acid, gene or chromosome.
The homologous nucleic acid sequence may have at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95% or more homology, or complete homology.
In addition, the additional component may be selectively used to improve the repair efficiency of the damaged gene or nucleic acid.
Assistor
The additional component may be used as an assistor to improve the repair efficiency of the damaged gene or nucleic acid.
The term “assistor” refers to a nucleic acid that serves to participate in a repair process or increase the repair efficiency of the damaged gene or nucleic acid, for example, the gene or nucleic acid cleaved by the guide nucleic acid-editor protein complex.
The assistor may be a double-stranded nucleic acid or single-stranded nucleic acid.
The assistor may be present in a linear or circular shape.
The assistor may be divided into an “NHEJ assistor” that participates in a repair process using NHEJ or improves repair efficiency and an “HDR assistor” that participates in a repair process using HDR or improves repair efficiency according to a repair method.
The NHEJ assistor may participate in a repair process or improve the repair efficiency of the damaged gene or nucleic acid using NHEJ.
For example, the NHEJ assistor may include a nucleic acid sequence having homology with a part of the damaged nucleic acid sequence. Here, the homologous nucleic acid sequence may include a nucleic acid sequence having homology with the nucleic acid sequence at one end (e.g., the 3′ end) of the damaged nucleic acid sequence, and include a nucleic acid sequence having homology with the nucleic acid sequence at the other end (e.g., the 5′ end) of the damaged nucleic acid sequence. In addition, a nucleic acid sequence having homology with each of the base sequences upstream and downstream of the damaged nucleic acid sequence may be included. The nucleic acid sequence having such homology may assist two parts of the damaged nucleic acid sequence to be placed in close proximity, thereby increasing the repair efficiency of the damaged nucleic acid by NHEJ.
The HDR assistor may participate in the repair process or improve repair efficiency of the damaged gene or nucleic acid using HDR.
For example, the HDR assistor may include a nucleic acid sequence having homology with a part of the damaged nucleic acid sequence. Here, the homologous nucleic acid sequence may include a nucleic acid sequence having homology with the nucleic acid sequence at one end (e.g., the 3′ end) of the damaged nucleic acid sequence, and a nucleic acid sequence having homology with the nucleic acid sequence at the other end (e.g., the 5′ end) of the damaged nucleic acid sequence. Alternatively, a nucleic acid sequence having homology with each of the base sequences upstream and downstream of the damaged nucleic acid sequence may be included. The nucleic acid sequence having such homology may serve as a template of the damaged nucleic acid sequence to increase the repair efficiency of the damaged nucleic acid by HDR.
In another example, the HDR assistor may include a nucleic acid sequence having homology with a part of the damaged nucleic acid sequence and a specific nucleic acid, for example, a nucleic acid or gene to be inserted. Here, the homologous nucleic acid sequence may include a nucleic acid sequence having homology with each of the base sequences upstream and downstream of the damaged nucleic acid sequence. The specific nucleic acid may be located between a nucleic acid sequence having homology with a base sequence downstream of the damaged nucleic acid and a nucleic acid sequence having homology with a base sequence upstream of the damaged nucleic acid. The nucleic acid sequence having such homology and specific nucleic acid may serve as a donor to insert a specific nucleic acid into the damaged nucleic acid, thereby increasing HDR efficiency for knockin.
The homologous nucleic acid sequence may have at least 50%, 55%, 60%, 65%, 70%, 75%, 80%, 85%, 90% or 95% or more homology or complete homology.

Targets for the treatment may be mammals including primates such as a human or a monkey, rodents such as a mouse or a rat, etc.
Diseases to be Treated
In an embodiment, diseases to be treated may be neovascularization-associated diseases.
The term “neovascularization-associated diseases” refer to all states including excessive and/or abnormal neovascularization. The neovascularization-associated diseases refer to disorders characterized by vascularization which is not changed or regulated, except tumorigenesis or neoplastic transformation, that is, cancer. The neovascularization-associated diseases include an ocular neovascularization disease.
Neovascular diseases include neovascularization-dependent cancer, for example, solid tumors, hematomas such as leukemia and tumor metastasis; benign tumors such as hemangiomas, acoustic neuromas, neurofibroma, trachomas and pyogenic granulomas; rheumatoid arthritis; psoriasis; ocular neovascularization diseases such as diabetic retinopathy, retinopathy of prematurity, macular degenerations including dry age-related macular degeneration and wet age-related macular degeneration, corneal graft rejection, neovascular glaucoma, retrolental fibroplasia, rubeosis; Osler-Webber Syndrome; myocardial neovascularization blindness; plaque neovascularization; telangiectasia; hemophiliac joint; angiofibromas; and wound granulation, but the present invention is not limited thereto.
In a certain embodiment, the neovascularization-associated diseases may be one or more diseases selected from the group consisting of rheumatoid arthritis, psoriasis, Osler-Webber Syndrome, myocardial neovascularization blindness, plaque neovascularization, telangiectasia, hemophiliac joint, angiofibromas, and wound granulation.
In an embodiment, the neovascularization-associated disease may be a disease including excessive and/or abnormal neovascularization.
In an embodiment, the neovascularization-associated disease may be neovascularization-dependent cancer.
Here, the neovascularization-dependent cancer includes solid tumors, hematologic tumors such as leukemia and tumor metastasis.
The neovascularization-dependent cancer may be, for example, solid tumors, hematologic tumors such as leukemia and tumor metastasis; benign tumors such as hemangiomas, acoustic neuromas, neurofibromas, trachomas and pyogenic granulomas.
In a certain embodiment, the neovascularization-associated disease may be a benign tumor.
The benign tumor may include hemangiomas, acoustic neuromas, trachomas and pyogenic granulomas.
In a certain embodiment, the neovascularization-associated disease may be an ocular neovascularization disease.
The term “ocular neovascularization disease” refers to all ocular diseases including excessive and/or abnormal neovascularization. The ocular neovascularization disease includes a disorder characterized by vascularization that is not changed or regulated in the eyes.
As an example, the ocular neovascularization diseases may include: ischemic retinopathy, optic papillary neovascularization, iris neovascularization, retinal neovascularization, choroidal neovascularization, corneal neovascularization, vitreous neovascularization, glaucoma, panus, pterygiums, macular edemas, diabetic retinopathy, proliferative diabetic retinopathy, diabetic macular edemas, vascular retinopathy, retinal degeneration, uveitis, inflammatory diseases of the retina, and proliferative vitreoretinopathy.
In one exemplary embodiment, the ocular neovascularization disease may be diabetic retinopathy or macular degeneration.
Diabetic Retinopathy
Diabetic retinopathy is a diabetic complication occurring in approximately 40 to 45% of the patients diagnosed with any one of Type 1 diabetes or Type 2 diabetes.
Diabetic retinopathy usually affects both eyes, and generally progresses in four stages. The first stage, that is, mild nonproliferative retinopathy is characterized by ocular microaneurysms. Small scaled swelling occurs in a retinal capillary tube and a small vessel. In the second stage, that is, moderate nonproliferative retinopathy, a blood vessel provided to the retina starts to be blocked. In the third stage, that is, severe nonproliferative retinopathy, the occlusion leads to a decrease in blood supply to the retina, and the retina sends a neovascularization signal to the eye in order to provide blood supply to the retina. In the fourth stage, that is, proliferative retinopathy, which is the most advanced stage, angiogenesis occurs, but the new blood vessel is abnormal, weak, and grows on the surface of a vitreous gel contained in the retina and the eyes.
The diabetic retinopathy includes insulin-dependent diabetes, insulin-independent diabetes, retinal detachment, diabetic retinopathy, and vitreous hemorrhage.
Macular Degeneration
The macular degeneration refers to a disease in which visual impairment is caused by macular degeneration, and is also called age-related macular degeneration (AMD).
The AMD includes early, intermediate and advanced AMD, and also includes all of dry AMD, for example, geographic atrophy, and wet AMD which is also known as neovascular or exudative AMD.
Dry macular degeneration is a prevalent type accounting for approximately 90% of the AMDs when a lesion such as a druse (the state in which waste is accumulated in the macula) or retinal pigment epithelial atrophy is generated in the retina. Wet macular degeneration is characterized by production of choroidal neovascularization under the retina.
Dry macular degeneration includes macular degeneration caused by a missense mutation in an immunoregulatory complement factor H (CFH) gene.
In another exemplary embodiment, a use of a system for regulating an additional, third in vivo mechanism, accompanied with various functions of specific factors artificially modified in function (e.g., a gene known as a neovascularization-associated factor, etc.) may be provided.
For example, the specific factors artificially modified in function may be one or more genes of a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene and an ANGPTL4 gene.
The third mechanism may be an in vivo mechanism in which the genes are involved, other than neovascularization.

Gene Manipulating Treatment
A treatment method for regulating neovascularization by manipulating a gene of a living organism may be used. Such a treatment method may be achieved by directly injecting a composition for manipulating a gene to manipulate the gene of a living organism into the organism.
The composition for gene manipulation may include a guide nucleic acid-editor protein complex.
The composition for gene manipulation may be injected into a specific location of the body.
Here, the specific location of the body may be tissue in which neovascularization excessively and/or abnormally occurs, or a location close thereto. For example, the specific location of the body may be, for example, the eyeball.

In one aspect, the present invention provides a method for modifying a target polynucleotide in prokaryotic cells, which may be achieved in vivo, ex vivo, or in vitro.
In some embodiments, the method may include sampling cells or a cell population from a human or non-human animal, and modifying the cell or cells. Culturing may occur at any step ex vivo. The cell or cells may also be reintroduced into a non-human animal or plant. The reintroduced cells are most preferably stem cells.
In still another exemplary embodiment, the present invention may provide a method for artificially manipulating cells, which includes: introducing (a) a guide nucleic acid capable of forming a complementary bond with the target sequences of SEQ ID NOs: 1 to 1522, for example, SEQ ID NOs: 1 to 79, of nucleic acid sequences of one or more genes selected from the group consisting of a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene and an ANGPTL4 gene or a nucleic acid sequence encoding the same; and (b) an editor protein including one or more proteins selected from the group consisting of a Streptococcus pyogenes-derived Cas9 protein, a Campylobacter jejuni-derived Cas9 protein, a Streptococcus thermophilus-derived Cas9 protein, a Streptococcus aureus-derived Cas9 protein, a Neisseria meningitidis-derived Cas9 protein, and a Cpf1 protein, or a nucleic acid sequence encoding the same to cells.

When a neovascularization-associated factor is artificially manipulated using the method and composition of some embodiments of the present invention, it is possible to regulate, for example, inhibit, suppress, stimulate and/or increase neovascularization, and therefore an effect of suppressing or improving excessive and/or abnormal neovascularization may be obtained.
Additional Uses
In a certain embodiment, the present invention may provide a kit for preparing a composition for treating AMD or diabetic retinopathy.
The kit may be prepared by a conventional preparation method known in the art.
The kit may further include a detectable label. The term “detectable label” refers to an atom or molecule for specifically detecting a molecule containing a label among the same type of molecules without a label. The detectable label may be attached to an antibody specifically binding to a protein or a fragment thereof, an interaction protein, a ligand, nanoparticles, or an aptamer. The detectable label may include a radionuclide, a fluorophore, and an enzyme.
In a certain embodiment, the present invention may provide a method for screening a material capable of regulating the expression level of one or more genes of an artificially manipulated VEGFA gene, HIF1A gene, ANGPT2 gene, EPAS1 gene and ANGPTL4 gene.
In a certain embodiment, the present invention may provide a method for providing information on the sequence of a target site which is able to be artificially manipulated in a subject by analyzing the sequences of one or more genes selected from the group consisting of a VEGFA gene, an HIF1A gene, an ANGPT2 gene, an EPAS1 gene and an ANGPTL4 gene.
In addition, a method for constructing a library using the information provided by such a method.
Here, a known database may be used.
In specific embodiments, an animal or cells which can be used for research using the method of the present invention may be provided.
An animal or cells which includes chromosome editing in one or more nucleic acid sequences associated with a disease may be prepared using the above-described method. Such a nucleic acid sequence may be a reference sequence which may encode a disease-associated protein sequence or may be associated with a disease.
In one exemplary embodiment, an effect of mutation and occurrence and/or progression of a disease may be studied in an animal or cells using measurements conventionally used in disease research with the animal or cells prepared by the method of the present invention. Alternatively, a pharmaceutical effect of an active compound in a disease using such an animal or cells may be studied.
In another exemplary embodiment, the effect of the strategy of a possible gene therapy may be evaluated using the animal or cells prepared by the method of the present invention. That is, the development and/or progression of a corresponding disease may be suppressed or reduced by modifying a chromosome sequence encoding a disease-associated protein. Particularly, this method includes forming a modified protein by editing a chromosome sequence encoding a disease-associated protein, resulting in the achievement of a modified response of the animal or cells. Therefore, in some embodiments, a genetically-modified animal may be compared with an animal vulnerable to the development of a corresponding disease, thereby evaluating the effect of a gene therapy process.
Such uses may include a disease model, a pharmacological model, a developmental model, a cell function model, and a humanized model. For example, a neovascularization-associated disease model, a pharmacological model, a developmental model, a cell function model, and a humanized model may be included.
An artificially manipulated neovascularization-associated factor and a neovascularization system artificially modified in function thereby can be effectively used to treat a neovascularization-associated disease, for example, a neovascularization-associated ocular disease (eye disease). The efficiency of a neovascularization system may be improved by regulating various in vivo mechanisms in which various neovascularization-associated factors are involved.
Hereinafter, the present invention will be described in further detail with reference to examples.
The examples are merely provided to describe the present invention in further detail, and it might be obvious to those of ordinary skill in the art that the scope of the present invention is not limited to the following examples.

2. Construction of CjCas9 and sgRNA Plasmids
A sequence encoding human codon-optimized CjCas9 (derived from Campylobacter jejuni subsp. Jejuni NCTC 11168) was synthesized to have a nuclear localization signal (NLS) and an HA epitope at the C-terminus (GeneArt™ Gene Synthesis, Thermo Fisher Scientific), and the synthesized nucleic acid sequence was replicated using a p3s plasmid described in previous research (Cho, S. W., Kim, S., Kim, J. M. & Kim, J. S. Targeted genome engineering in human cells with the Cas9 RNA-guided endonuclease. Nature Biotechnology 31, 230-232 (2013)).
A tracrRNA (transactivating crRNA) sequence and a pre-crRNA (precursor CRISPR RNA) sequence were connected using a GAAA or TGAA linker, thereby producing sgRNA. The sgRNA regulated transcription with an U6 promoter.
3. PAM Characterization Using Cell-Based Reporter Analysis
An AAVS1 target site (AAVS1-TS1) having a variable PAM sequence (5′-NNNNXCAC-3′, 5′-NNNNAXAC-3′, 5′-NNNNACXC-3′, and 5′-NNNNACAX-3′) including a random sequence at the X site was synthesized (Macrogen, Inc.), and the synthesized nucleic acid sequence may be replicated using a surrogate reporter plasmid encoding RFP and GFP.
To determine a suitable PAM sequence, the constructed reporter plasmid (100 ng), and plasmids encoding CjCas9 (225 ng) and sgRNA (675 ng) were co-transfected into HEK293 cells (1×10⁵) using lipofectamine 2000 (Invitrogen). Two days after the transfection, a fractionation of the GFP and RFP-positive cells was measured by flow cytometry (BD Accuri™ C6, BD).
4. Cell Culture and Mutation Analysis
HEK293 (ATCC, CRL-1573) cells and mouse NIH 3T3 (ATCC, CRL-1658) cells were cultured in a Dulbecco's modified Eagle's medium (DMEM) supplemented with 100 units/mL penicillin, 100 mg/mL streptomycin, and 10% fetal bovine serum (FBS).
A sgRNA plasmid (750 ng) and a CjCas9 plasmid (250 ng) were transfected into cells (0.5˜1×10⁵) using lipofectamine 2000 (Invitrogen). 48 hours after the transfection, genome DNA was separated using a DNeasy blood & tissue kit (Qiagen), and an on-target or off-target site was amplified for targeted deep sequencing. Deep sequencing libraries were generated by PCR. TruSeq HT Dual Index primers were used to label respective samples. Mixed libraries were subjected to paired-end sequencing (LAS, Inc.), and indel frequencies were calculated.
5. Construction of AAV Vectors Encoding CjCas9 and sgRNA Sequences
An AAV inverted terminal repeat (ITR)-based vector plasmid containing an sgRNA sequence and a CjCas9 gene having NLS and HA tags at the C-terminus was constructed. sgRNA transcription was induced by an U6 promoter, and CjCas9 expression was regulated by an EFS promoter in C2C12 myoblasts, or by a Spc512 promoter in the TA muscle of C57BL/6 mice.
For retinal delivery, an AAV vector encoding the U6 promoter-induced sgRNA and CjCas9 under the control of the EFS promoter, specific to the Vegfa gene and Hif1a gene, was constructed, wherein CjCas9 had eGFP linked to the C-terminus using a self-cleaved T2A peptide.
6. Production, Purification and Characterization of AAV Vector
To produce the AAV vector, a pseudotype of AAVDJ or AAV9 capsids was used. The HEK293T cells were transfected with pAAV-ITR-CjCas9-sgRNA, pAAVED2/9, and a helper plasmid. The HEK293T cells were cultured in a 2% FBS-containing DMEM. Recombinant AAV vector stocks were produced using PEI coprecipitation by mixing polyplus-transfection (PElpro), triple-transfection and the plasmid in a molar ratio of 1:1:1 in the HEK293T cells. After 72 hours of culturing, the cells were lysed, and particles were isolated and purified with iodixanol (Sigma-Aldrich) by step-gradient ultracentrifugation. The number of vector genomes was quantified through quantitative PCR.
7. AAV Transduction in Mouse Myoblasts
Mouse myoblasts were infected with various viral amounts of AAVDJ-CjCas9 (multiplicity of infection (MOI): 1, 5, 10, 50, and 100 (determined by quantitative PCR)), and cultured in 2% FBS-containing DMEM. For the target deep sequencing, cells were obtained at different points of time. MOI 1 is considered as infection by one virus particle among a total of 100 virus particles determined by quantitative PCR.
8. Animals
Management, use and treatment of all animals used in this research were performed under the guidance provided by the Seoul National University Animal Care and Use Committee, ophthalmology and security research, and the strict agreement according to the ARVO statement on animal use in veterinary medicine. In this research, specific male pathogen free (SPF)-6-week old C57BL/6J mice were used. The mice were maintained in a 12-hour light/dark cycle.
Diabetic model mice were induced by injecting streptozotocin (STZ, Sigma-Aldrich, St. Louis, Mo., USA) intraperitonially once. As a control, a citrate buffer was injected. 4 days after the STZ injection, when a blood glucose level of the mouse was 300 mg/dl or more, diabetes was considered to be induced.
9. Injection of AAV into Vitreous Body
A mixture of tiletamine and zolazepam in a ratio of 1:1 (2.25 mg/kg (body weight) each), and 0.7 mg/kg (body weight) of xylazine hydrochloride was injected into a vitreous body of a 6-week old mouse for anesthetization. 2 μl (2×1010 viral genome) of AAV9-CjCas9 was injected into the vitreous body using a Nanofil syringe (World Precision Instruments Inc.) having a 33G blunt needle under a surgical microscope (Leica Microsystems Ltd.).
In the case of diabetic mouse models, the mice were injected with STZ to induce diabetes, anesthetized after 1 or 7 weeks, and 2 μl of the mixture containing 0.8×108 vg/μl of CjCas9:Vegfa or 1.5×109 vg/μl of Rosa26 was injected in the vitreous body.
10. Immunofluorescence Staining and Imaging of Retinal Tissue
42 days after the injection, the sample was fixed with formalin and embedded in paraffin (n=4). A sample obtained by cross-section of the sample-embedded paraffin was immunostained with an anti-HA antibody (Roche, 3F10, 1:1000), an anti-opsin antibody (Millipore, AB5405, 1:1000), and an Alexa Fluor 488 or 594 antibody (Thermo Fisher Scientific, 1:500). An opsin-positive site was detected in RPE cells expressing HA-tagged CjCas9 using Image J software (1.47v, NIH). The distribution of CjCas9 and eGFP was visualized on RPE flat-mounts using a confocal microscope (LSM 710, Carl Zeiss).
11. Extraction of Genome DNA
To extract DNA from RPE and the retina, after obtaining images of RPE and the retina flat-mounts, the tissue samples were washed with PBS. RPE cells were separated from the choroid/sclera by vortexing for 30 seconds in a lysis buffer (NucleoSpin Tissue, Macherey-Nagel). Genome DNA was analyzed to identify complete isolation of the RPE cells from remaining choroid/sclera tissue. The genome DNA was analyzed by target deep sequencing.
12. Mouse Vegfa ELISA
42 days after the injection, a total RPE mixture was isolated from neural retina tissue, and two kinds of tissue were frozen for subsequent analysis. The sample tissue was lysed in 120 μl of a cell lysis buffer (CST #9803), and the amount of a Vegfa protein was measured using a mouse VEGF Quantikine ELISA kit (MMVOO, R&D Systems).
13. Laser-Induced CNV Model
After anesthetization of a mouse, eye drops containing 0.5% phenylephrine and 0.5% tropicamide were injected to dilate a pupil. Laser photocoagulation was performed using an indirect head set delivery system (Iridex) and a laser system (Ilooda). Parameters of the laser are a wavelength of 532 nm, a spot size of 200 μm, a power of 800 mW and exposure time of 70 ms. A laser burn was induced in the proximity of the optical nerve three to four times. Burns in which bubbles are generated without bleeding of the vitreous body were only used for the research. After 7 days, an eyeball was fixed with 4% paraformaldehyde at room temperature for one hour. An RPE mixture (RPE/choroid/sclera) was immunostained overnight at 4° C. using isolectin-B4 (Thermo Fisher Scientific, cat. no. 121413, 1:100) and an anti-GFP antibody (Abcam, ab6556, 1:100). The RPE mixture was flat-mounted, and visualized using a fluorescent microscope (Eclipse 90i, Nikon) or a confocal microscope (LSM 710, Carl Zeiss) at a 100× magnification. A CNV site was detected using Image J software (1.47v, NIH). An average of three to four CNV sites per eyeball was analyzed. Each group consists of 17 to 18 eyeballs.
14. Quantitative and Qualitative Analyses for Rupturing of Retinal Vessels
To detect vascular leakage, STZ-induced diabetic mouse models were used. 200 μl of an Evans blue dye (20 mg/ml) dissolved in PBS was intravenously injected into an anesthetized mouse. Two hours after perfusion, an eyeball was extracted to be fixed with 4% paraformaldehyde for 1 hour. The retina was excised in 2×PBS and flat-mounted, and images of the retina were obtained at 40× and 100× magnifications using a fluorescent microscope (Eclipse 90i, Nikon).
To quantitatively analyze the vascular leakage, representative four sites of the vascular leakage in the mid-peripheral retina (0.5 μm×0.5 μm) of each mouse were selected. The mid-peripheral retina was designated as the middle 1/3 of the retina from the optic nerve head to the ciliary body, images were modulated according to color threshold values based on the automatic isodata algorithm using the Image J software (1.47v, NIH), and regions of interest containing the Evans blue dye were marked in red. Afterward, the regions marked in red were detected. The data were normalized with data of control mice, and represented as vascular leakage (%).
15. Data Analysis
To previously determine a sample size in vitro or in vivo, a statistical method was not used. For statistical analysis, one-way ANOVA and Tukey post-hoc tests were used.

Example 1. Confirmation of CjCas9 Expression Through AAV in Mouse Retinal Tissue

Since CjCas9 consisting of 984 amino acids has a considerably smaller size (2.95 kbp) than SpCas9, both CjCas9 gene and sgRNA are able to be packaged in one AAV vector. Therefore, in this example, to confirm the possibility of gene manipulation using CjCas9 as a method for treating AMD, CjCas9-expressing AAV was used.
To confirm the expression of CjCas9 through AAV in tissue such as the retina in a mouse, under the control of U6 promoter-induced sgRNA and an EFS promoter specific to a choroidal neovascularization (CNV)-associated Vegfa gene and an Hif1a gene, a CjCas9-coding AAV9 vector was constructed, and here, CjCas9 was linked to eGFP at the C-terminus using a self-cleaved T2A peptide (FIGS. 1 and 2). The constructed virus was injected into an eyeball through injection into the vitreous body, and after 6 weeks, CjCas9 expression in the eyeball was confirmed, an indel frequency was measured using target deep sequencing, and the amount of Vegfa protein was measured through ELISA (FIG. 4).
The expression of the CjCas9-linked eGFP was confirmed in retinal pigment epithelial (RPE) cells (FIG. 8).
In addition, indels induced by CjCas9 were observed at Rosa26, Vegfa, and Hif1a target sites of the RPE cells, indel frequencies of 14±5%, 22±3%, and 31±2% were confirmed, respectively (FIG. 3). In addition, noticeable off-target indels were not induced by Vegfa- or Hif1a-specific sgRNA in the cells (FIG. 5).
As expected, the expression level of the Vegfa protein was decreased in AAV-treated RPE cells encoding Vegfa-specific CjCas9 (AAV-CjCas9: Vegfa), but was not when Hif1a- or Rosa26-specific CjCas9 (AAV-CjCas9: Hif1a or Rosa26)-coding AAV was treated (FIG. 4). Particularly, since a Hif1a protein is degraded under a normoxia condition, the expression level of the protein was not able to be measured.

Example 2. Effect of Vegfa- or Hif1a-Specific AAV-CjCas9 Using CNV-Induced Mouse

To induce CNV, an eyeball was injected with AAV, and after 6 weeks, subjected to laser treatment, followed by detecting the CNV sites one week after the laser treatment (FIG. 6). When AAV-CjCas9: Vegfa and AAV-CjCas9: Hif1a were injected onto respective eyeballs, it was confirmed that, compared with an AAV-free negative control, CNV sites were decreased 24±4% and 20±4%, respectively (FIGS. 6 and 7). In the case of another negative control, that is, Rosa26-specific CjCas9, no therapeutic effect was confirmed, either.

Example 3. Effect of AAV-CjCas9 for AMD Treatment

Since cone dysfunction is caused by conditional knockout of a Vegfa gene in the mouse RPE cells, the cause of side effects by the AAV-induced gene knockout in the RPE cells was investigated. To this end, the size of a cone function-related opsin-positive site in the retina was measured. As a result, the Vegfa-specific CjCas9 was decreased in size by approximately 30±10% the AAV-free control (FIGS. 9 and 10). However, as expected, the Hif1a- or Rosa26-specific CjCas9 did not induce cone dysfunction. Such a result may suggest that Hif1a inactivation for treatment of AMD inhibits neovascularization and does not cause cone dysfunction.
HIF1A is a hypoxia-inducible transcription factor, and serves to activate VEGFA transcription. Unlike VEGFA, which is a primary therapeutic target for AMD treatment and a secretory protein, HIF1A may not be considered as a drug target, and generally, a transcription factor such as HIF1A may not be directly targeted by an antibody or aptamer, or small molecules. In this research, as the Hif1a gene was effectively inactivated in the RPE cells using CjCas9 targeting the Hif1a gene on the eyeball of a mouse, it was confirmed that the CNV sites were reduced in the AMD mouse models (FIGS. 9 and 10).

Example 4. Effect of AAV-CjCas9 for Treatment of Retinal Disease

For extended application to retinal diseases such as diabetic retinopathy (DR), retinopathy of prematurity, etc., the constructed virus was injected into the eyeball through injection into the vitreous body, and 6 weeks later, the in vivo genome editing effect caused by the indel frequency in retinal tissue was observed by target deep sequencing, followed by confirming an expression level of the Vegfa protein through ELISA (FIG. 2). In the retinal tissue, the indels induced by CjCas9 were observed at the Rosa26, Vegfa, and Hif1a target sites in the retinal cells, indel frequencies of 44±8%, 20±2%, and 58±5% were confirmed, respectively (FIG. 11). As expected, an expression level of the Vegfa protein was decreased in retinal cells when treated with AAV encoding Vegfa- or Hif1a-specific CjCas9 (AAV-CjCas9: Vegfa or Hif1a), but did not when AAV encoding Rosa26-specific CjCas9 (AAV-CjCas9: Rosa26) was treated (FIG. 12).

Example 5. Effect of AAV-CjCas9 for Treatment of Diabetic Retinopathy

Diabetic retinopathy is characterized by the symptoms of vascular leakage and blood leakage. Therefore, in this example, the vascular leakage or blood leakage symptom was confirmed using diabetes-induced mice using STZ, and an improvement or treatment effect caused by CjCas9 was confirmed. As a result, it was confirmed that the blood leakage caused by vascular leakage and rupturing was decreased in the Vegfa-specific CjCas9 (AAV-CjCas9: Vegfa)-injected retina. Compared with Rosa26-specific CjCas9 (AAV-CjCas9: Rosa26)-injected mice, vascular leakage and blood leakage in Vegfa-specific CjCas9 (AAV-CjCas9: Vegfa)-injected mice were decreased and thus recovered to a level similar as in normal mice of the same age. Such a result was similarly shown in both of an experiment in which STZ was injected, AAV-CjCas9 was injected after 7 weeks and observation was performed after 6 weeks (FIG. 13), and an experiment in which STZ was injected, AAV-CjCas9 was injected after 14 weeks and observation was performed after 7 weeks (FIGS. 14 and 15). According to the above results, it was confirmed that Vegfa-specific CjCas9 (AAV-CjCas9: Vegfa) has an effect of reducing vascular leakage and blood leakage, and thus it can be expected that the Vegfa-specific CjCas9 (AAV-CjCas9: Vegfa) can effectively treat diabetic retinopathy.

Example 6. Screening of Target Site of Human Neovascularization-Associated Factor

To extend the application of the previously-described example, in addition to human VEGFA (FIG. 16) and human HIF1A (FIG. 17), human ANGPT2 (FIG. 19), human EPAS1 (FIG. 20) and human ANGPTL4 (FIG. 21) were selected as potential targets of genome editing for AMD and DR treatments to screen the target site of each gene capable of being effectively edited in human cells using a CjCas9 system. Particularly, the CjCas9 target site of the mouse Hif1a gene was completely conserved in a human or a different mammal (FIG. 18). Additionally, the high editing efficiency of the conserved target site was observed in human cells (FIG. 17, sgRNA #7). Therefore, it is expected that AAV for Hif1a suggested in this research or a mutant thereof is able to be used in treatment of a future human patient.
