Definitions
- Oligonucleotides directed against a survivin gene Oligonucleotides directed against a survivin gene
- the present invention relates to oligonucleotides which are directed against a survivin gene and the use of these oligonucleotides for the diagnosis, prophylaxis, reduction, follow-up control of diseases associated with cell growth, differentiation and / or division, such as, for example, tumor diseases.
- Survivin which belongs to the gene family of inhibitors of apoptosis (IAP), is a recently discovered link ("interface molecule") between cell cycle progression and apoptosis control. It is a 142 amino acid long protein with a molecular weight of approx. 16.5 kDa. The gene is located on the long arm of chromosome 17 (17q25) (Ambrosini et al., 1997; Adida et al. 1998). Survivin is usually expressed during embryonic and fetal development, but only to a very limited extent in adult tissues, the former being the Tissue homeostasis and differentiation contributes (Adida et al. 1998). Interestingly, survivin is primarily expressed during the G2 / M phase.
- survivin in tumor cells can override the apoptosis checkpoint in the G2 / M phase and allow progression of transformed cells through mitosis (Li et al. 1998).
- Survivin is overexposed in numerous malignant tumors, such as lung, colon, stomach, breast, pancreas, prostate, bladder carcinoma, large cell non-Hodgkin's lymphoma, melanoma and in neuroblastoma and plays a part in the genesis and in particular the progression of these tumors play an essential role
- a disadvantage of the previous disclosures is that the person skilled in the art has no effective and specific therapeutic approaches that could be used in organisms, especially higher organisms, such as mammals, especially humans.
- Numerous previous disclosures describe very large constructs that interact with the survivin gene. With such large constructs, effects can be achieved in certain cell suspensions or other cultures.
- higher organisms which have an effective immune defense and numerous enzymatic control mechanisms, such large constructs or substances interacting with Survivin are immunologically attacked, destroyed or disadvantageously modified before they interact with the actual target molecule and thus develop a specific effect in the organism can.
- the stability of relatively large constructs or substances is limited when used in humans.
- the accessibility and target-specific movement of the constructs and substances in the body is limited. Such negative side effects are unpredictable, difficult controllable and therefore represent a relatively high safety risk in the context of treatment in humans, for example against a malignant tumor disease.
- the object of the invention was therefore to provide alternative molecules which interact simply, safely and effectively with specific secondary structure motifs of the mRNA of the survivin gene.
- the invention solves this technical problem by ⁇ the provision of oligonucleotides directed against the mRNA of survivin gene (database entry NM_001168) and / or its gene and ⁇ transcript, wherein the oligonucleotides with mRNA target designs of the Survivin gene interact specifically in a sequence range from 30 to 1350.
- the numbers in the further text refer to the corresponding nucleotide positions within the survivin mRNA (total length 1619 nucleotides).
- the invention thus relates to the surprising teaching that a highly specific and very efficient interaction with the survivin mRNA is possible with the oligonucleotides according to the invention.
- the person skilled in the art can, by disclosing the teaching according to the invention, specific oligonucleotides such as antisense constructs, ribozymes, DNAzymes or siRNA constructs generate, which interact with 'to the target sequence region that survivin expression inhibited, reduced and / or inhibited.
- other molecules that are able to interact with the corresponding sequence regions can of course also be selected; such as B. ' Antibodies, affilines, lectins or aptamers.
- the oligonucleotides according to the invention can be used in vivo and in vitro, for example to attack the target mRNA of survivin temporarily and intracellularly in a specifically efficient manner and thus to inhibit the oncogenic function of tumor-associated abnormal survivin expression.
- the oligonucleotides according to the invention can thus be used, for example, in a diagnostic or therapeutic method or can be used in a kit for therapeutic purposes.
- Another method can be, for example, additive therapy for humans to treat human tumors locally and / or systemically, e.g. with other nucleic acid-based constructs, immunotherapeutics, chemotherapeutic agents, radiation and other methods for tumor treatment in combination with the use of oligonucleotides according to the invention.
- Target sequence ranges from 33 - 52, 41 - 60, 49 - 68, 92 - 114, 261 - 280, 264 - 283, 278 - 297, 282 - 301, 283 -
- the Survivin gene effectively inhibit, in particular by the oligonucleotides specifically interact with the mRNA secondary structure.
- the oligonucleotides preferably interact with the target sequence region of 92-114, 261-280, 264-283, 283-305, 286-305, 504-523, 532-551 and / or 743-762 of the mRNA of the survivin gene.
- the siRNA very particularly preferably interact with the areas 92-114, 262-270-IVS2 1-14, 262-270 / 389-401, 283-305.
- the sequence region and / or the oligonucleotide is changed by addition, amplification, inversion, missense mutation, nonsense mutation, point mutation, deletion and / or substitution.
- parts of the target sequences mentioned are used with changes within or with changed edge areas or different derivatizations / modifications / fusions / complexations.
- oligonucleotides according to the invention with molecules which support the directed transport to the target site, the uptake into and / or the distribution within a target cell; such molecules. are known to the person skilled in the art or in Kappler et al. (2004).
- the mutations in the sequence region of the survivin gene and its transcript variants can, for example, be inheritable or non-inheritable changes in the sense of the invention.
- mutations in connection with a Count gene and / or chromosome mutations associated with changes in the survivin gene and its transcript variants can arise from the fact that parts of the chromosome are lost, doubled, have the opposite orientation or are transferred to other chromosomes.
- the mutation affects only one or a few neighboring base pairs, as is the case for example with the point mutation.
- a codon can be converted into a synonymous codon
- the mutation ends the translation at a specific point, and the survivin fragments formed can be inactive or active.
- the oligonucleotide is a nucleic acid construct.
- Nucleic acid constructs in the sense of the invention can be all structures which are essentially based on nucleic acids or whose active center is essentially based on nucleic acids. It can of course be possible that part of the oligonucleotide / construct from lipids, carbohydrates. or proteins or peptides - for example in the form of a nanocapsule - and this construct comprises a region which contains nucleic acids which in particular have the sequence region of 33 -

- Tab. 1 AS effects and their mechanisms of action ss - "single stranded" (single strand)
- AS-ON as therapeutic substances is one of several other fields of application in particular also represents a new promising therapy concept for oncological diseases. While conventional chemotherapy leads to non-specific inhibition of cell proliferation, antisense therapy can specifically inactivate those mRNAs that form the molecular basis for the degenerate, deregulated growth and the Represent tumor progression and may be responsible for the inhibition of the body's immune defense.
- AS-ON differ from other therapeutic agents, such as antibodies, toxins or immunotoxins, in that they are relatively small molecules with a molecular weight of usually about 5 kDa.
- the small size of the AS-ON enables good tissue penetration.
- tumor blood vessels are permeable to substances in a size range between 4-10 kDa. This means that therapeutic AS-ON tumor blood vessels can penetrate better.
- Another advantage of these substances for example compared to antibodies that are only effective against extracellular proteins, is that, in addition to the membrane-bound proteins, both cytoplasmic and nucleus-localized proteins can be attacked using the respective target mRNA by means of antisense technology.
- non-antisense effects when using the phosphothioate oligonucleotides (PS-ON), in addition to the above-mentioned target-specific AS effects, so-called “non-antisense” effects also advantageously occur, which in particular lead to a non-specific Inhibition of cell growth- lead.
- These effects are strongly dependent on the oligo sequence or of 'certain sequence motifs and occur because of the strong polyanionic charge of the PS-ON, which may have a binding of the PS-ON of vital proteins result.
- the effects mentioned could be overcome by partially phosphothioate-modified AS-ON or by further modifications, for example the incorporation of ribonucleotides instead of deoxyribonucleotides.
- a terminal modification of ON constructs offers in particular improved stability when applied in vivo and in the extra- and intracellular environment of the target cells, such as in particular the protection against degradation by exonucleases.
- a positive effect when using PS-ON is its immunostimulatory effect, which can support possible therapeutic success in some tumor applications.
- Ribozymes are 'as catalytically active RNA molecules capable of cellular RNA structures to recognize as substrates and sequence-specifically cleave phosphodiester bond at a specific sequence NUX. The detection takes place via AS arms, which enable hybridization with the target mRNA due to complementary sequences.
- AS-ON ribozymes have the fundamental advantage that a ribozyme molecule as a real catalyst can convert a large number of identical substrate molecules. Therefore, ribozymes are already effective in a much lower concentration than ON and also lead to irreversible RNA degradation due to substrate cleavage [Sun et. al.].
- ribozymes Compared to antisense-ON, ribozymes have the advantage that a ribozyme molecule can act as a real catalyst in a multiple-turnover reaction and convert a large number of identical substrate molecules. Therefore, ribozymes are advantageously effective at a lower concentration than AS-ON and, moreover, lead to irreversible inhibition of the RNA by the substrate cleavage.
- the hammerhead ribozyme (review: Birikh et al. 1997; Tanner 1999) is particularly advantageous for such applications because it can be catalytically active as a comparatively small molecule (approx. 30-50 nucleotides).
- a very 'effective trans-cleaving hammerhead ribozyme is composed for example of only 14 conserved nucleotides in the catalytic domain and two variable stem sequences - advantageously of each 6 - 8 nucleotides -, by Watson-Crick base pairing - analogous to the AS-ON - the Realize sequence-specific recognition of the substrate and then inactivate it by cleaving a phosphoric diester bond.
- RNA interference as a method of gene inhibition is advantageously mediated by small synthetically produced RNA oligonucleotides ("small interfering RNAs", siRNA), which enable selective inhibition of the intracellular synthesis of survivin.
- siRNAs small synthetically produced RNA oligonucleotides
- dsRNA double-stranded RNA
- mRNA single-stranded target RNA
- siRNAs short interfering dsRNAs
- siRNAs short RNA duplexes
- siRNAs have a characteristic length of 21-23 nt with a 2 nt long single strand overhang at the 3 'terminus of both chains.
- the sequence of this siRNA now determines the recognition of homologous mRNA regions and their degradation by activating cell-specific RNases. In this way, the protein synthesis of the repressed target gene can be influenced directly, and thus switching off of the target protein can be induced.
- siRNA blocks the flow of information in the cell by inhibiting the translation of survivin and its variants.
- siRNAs can advantageously inhibit other RNA molecules that are not translated and thus only act on the RNA level.
- the oligonucleotide or the oligonucleotides are immobilized.
- immobilization means different methods and techniques for fixing the oligonucleotides on specific supports.
- the immobilization can serve, for example, to stabilize the oligonucleotides, as a result of which their activity, in particular during storage or in the case of a single batch approach, is not modified or reduced or disadvantageously modified by biological, chemical or physical effects.
- the immobilization of the oligonucleotides enables repeated use under routine technical or clinical conditions. Furthermore, the sample can be continuously reacted with the oligonucleotides.
- crosslinking In the crosslinking, the oligonucleotides are fixed to one another without their activity being adversely affected; they are advantageously no longer soluble.
- Binding to a carrier takes place, for example, by adsorption, ion binding or covalent binding. This can also take place within microbial cells or liposomes or other membrane-containing closed or open structures.
- the oligonucleotide is advantageously not influenced in its specificity / activity by the fixation. It can advantageously be used multiple times or continuously, for example in the clinic, for diagnosis or therapy in a vehicle-bound manner.
- (iii) Inclusion takes place in the sense of the invention in particular on a semipermeable membrane in the form of gels, fibrils or fibers.
- Encapsulated oligonucleotides, such as antisense constructs are separated by a semipermeable membrane from the surrounding sample solution in such a way that they advantageously still have the sequence range from 33-52, 41-60, 49-68, 92-114, 261-280 , 264 - 283, 278 - 297, 282 - 301, 283 - 305, 286 - 305, 501 - 520, 504 - 523, 516 - 535, 519 - 538, 526 - 545, 532 - 551, 716 - 735, 719 - 738, 724 - 743, 740 - 759, 743 - 762, 1126 - 1145, 1128 - 1147, 1302 - 1321, 1304 - 1323, 1317 - 13
- Various methods are available for immobilization, such as adsorption onto an inert or electrically charged inorganic or organic carrier.
- Such carriers can be, for example, porous gels, aluminum oxide, concrete, agarose, starch, nylon or polyacrylamide.
- the immobilization takes place through physical / chemical binding forces, often with the participation of hydrophobic interactions and ionic bonds.
- Such methods are advantageously easy to use and do not influence the conformation of the oligonucleotides, or only to a minor extent.
- the binding can advantageously be improved by electrostatic binding forces between the charged groups of the oligonucleotides and the carrier.

- the reaction space of the oligonucleotides is limited with the help of membranes.
- the microencapsulation can be carried out, for example, as an interfacial polymerization. Immobilization during microencapsulation makes the oligonucleotides insoluble and therefore reusable.
- immobilized oligonucleotides are all oligonucleotides which are in a state which permits their reuse. The restriction of the mobility and the solubility of the oligonucleotides by chemical, biological or physical means advantageously leads to low process costs.

This reaction could be verified by demonstrating reduced survival of the cells treated in this way. Cell colony formation tests showed a reduced cell viability of approx. 50% compared to the nonsense control (Fig. 8).
- Fig. 7 siRNA-specific reduction in survivin protein expression: WTS cell lines (A204, US8 / 93, RD, SK-LMS, Saos-2) were 6 h with 300 nM siRNA 1-2 (complexed with oligofectamine in the w / w ratio 1: 1) transfected and harvested 24 h after the start of the transfection.
- the survivin protein content was quantified in the Survivin ELISA (R&D) 24 hours after the transfection.
- the survivin concentration (pg / ml) was related to the total protein concentration (mg / ml).
- the absolute mean values pg survivin / ⁇ g protein
- the nonsense control siRNA 3-4 treated cells were set equal to 100% and the result was that of 300 nM each siRNA 1-2 treated cells with a relative amount of transcription (with standard deviations).
- Fig. 8 Representation of the plating license of the WTS cell line (A204, US8 / 93, RD, SK-LMS, Saos-2)) these were 6 h with 300 nM siRNA 1-2 (complexed with oligofectamine in a w / w ratio) 1: 1) transfected and 24 h after the start of the transfection in a defined manner in cell culture bottles. After 14 days of growth, the grown-up cell colonies were counted and placed in relation to the cell-specific nonsense-siRNA 3-4 treated control.
- the named constructs were combined with various chemotherapeutic agents.
- the BCa-relevant cytostatics cisplatin, gemcitabine and mitomycin-C would be used.
- the chemotherapy the previous transfection with 'og oligonucleotides resulted in remarkable and unexpected enhancement effects in terms of anticancer activity compared to the combination with the control constructs.
- the combined treatment serves to specify chemotherapy and in this way allows a dose minimization of conventional forms of therapy.
- some of the tumor cell lines, which are considered resistant per se were " sensitized to individual chemotherapeutic agents.
