Definitions
- the present invention relates to polynucleotides which are directed against a gene of a catalytic subunit of human telomerase (hTERT) and to the use of these polynucleotides for the diagnosis, prophylaxis, treatment, monitoring of diseases associated with cell growth, differentiation and / or division , such as tumor diseases.
- hTERT human telomerase
- telomeres Chromosome ends are responsible, among other things, for controlling the ability of proliferation and thus for the aging of cells [Harley]. The structure of these telomeres has been studied in numerous living systems.
- RNA component hTR
- hTERT catalytic subunit
- telomere activity was detected in immortalized cell lines and in> 85% of the tumors examined [Kim et al. ]. This correlates with the expression of the hTERT component, as has been shown in bladder cancer [Ito et al. ]. There is also a connection between the level of hTERT expression in bladder carcinoma and the clinical course of the tumor disease (de Kok et al.). Therefore, human telomerase is an ideal target for the diagnosis and treatment of human diseases associated with cellular proliferation. such as cancer, methods for diagnosing and treating cancer and other diseases associated with telomerase are disclosed, inter alia, in US 5,489,508 or US 5,645,986.
- telomere activity has been shown as a specific way to therapeutically control tumor cells described. Important efforts to modify the activity of telomerase in the context of cancer are disclosed in EP 666313, WO 97/37691, WO 99/50279, US 2002/0045588 AI or WO 98/28442. Such general teachings do not reveal to the skilled person specific teachings on technical action.
- a substance or a molecule that interacts with the entire sequence region coding for hTERT leads to a reduction in the corresponding telomerase activity, for example in a cell culture, but such substances are not suitable for application in organisms, since they usually are much too large and are attacked and destroyed by the immune system of the organism in question. In addition, a large number of undesirable interactions or side effects can occur. It was therefore an object of the invention to provide alternative compact molecules which have a simple and effective inhibitory interaction with selected, specific structural units which encode the telomerase.
- hTERT is directed, wherein the polynucleotide specifically interacts with primary structures of this hTERT mRNA in two target sequence regions from 2176 to 2250 and 2296 to 2393 according to the gene database entry AF 015950.
- the numbers represent - also in the following sections - the corresponding nucleotide positions within the hTERT mRNA (total length 4015 nucleotides).
- the invention thus relates to the surprising teaching that against tumor-associated abnormal hTERT-mRJ-IA expression onsmus ⁇ -.er suw-.e telomerase activity levels by a possible hTER inhibition with the polynucleotides according to the invention.
- polynucleotides are directed against defined hTERT mRNA sequence motifs in the range from 2000 to 2500. They can be biological and / or chemical structures that are able to interact with the target sequence area in such a way that a specific recognition / binding and interaction can be determined. Examples of polynucleotides can in particular be nucleic acid constructs and their derivatives. Of course, it is also possible to use other recognition molecules instead of or in combination with the polynucleotides, such as, for. B. antibodies, lectins, affilines, aptamers, chelators and others.
- the polynucleotide specifically interacts with two target sequence regions 2176 to 2250 and 2296 to 2393.
- particularly efficient hTERT inhibition is possible in these sequence regions.
- shorter areas with changes within these target sequences or with changed edge areas or different derivatizations / modifications / fusions / complexations which can also be combined and / or coupled with other recognition molecules such as polynucleotides.
- target sequence regions make it possible for the person skilled in the art to provide, in particular, very small and / or compact polynucleotides that essentially do not interact with other structures, in particular immunological defense structures, within the cell tissue or the organism or are attacked by them, but rather can specifically interact with the target sequence region of the hTERT mRNA.
- the sequence region or the recognition molecule in particular the polynucleotide, is modified by addition, amplification, inversion, missense mutation, nonsense mutation, point mutation, deletion and / or substitution.
- modifications can, for example, result in the polynucleotide binding to the mRNA of the hTERT catalytic subunit with a higher avidity or specificity.
- the polynucleotide binds with less specificity or avidity.
- the mutations in the hTERT sequence region can be, for example, inheritable or non-inheritable changes.
- the modifications can be such that they can be detected directly at the RNA level or at the DNA level.
- the mutations can also include, for example, mutations in connection with a cytologically visible genome and / or chromosome mutations which are associated with changes in hTERT. Such mutations 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 is only one or a few neighboring base pairs, as is the case with point mutation, for example. If, for example, a base pair is lost in the form of a deletion or if a base pair is additionally inserted, as in the insertion, the reading frame of the gene concerned shifts to a reading frame mutation.
- substitution mutation in the sense of the invention, for example, one base is exchanged for another, the consequences resulting therefrom being different:
- a codon can be converted into a synonymous codon
- the mutation ends the translation at a specific point, and the hTERT fragments formed can be inactive or active.
- the polynucleotide 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.
- the polynucleotide can be part of complexes or formulations consisting of lipids, carbohydrates or proteins or peptides, for example in the form of a nanocapsule. This complex or formulation comprises an area which contains nucleic acids which can interact with hTERT.
- the specialist Various ways are known to provide such constructs.
- the nucleic acid construct is an antisense (AS) oligonucleotide (ON), a DNAzyme, a ribozyme, an siRNA and / or a peptide nucleic acid (PNA).
- AS antisense
- ON oligonucleotide
- PNA peptide nucleic acid
- AS constructs are synthetically produced molecules that enable selective inhibition of the biosynthesis of selected proteins. For example, ON, PNAs, ribozymes, DNAzymes are used.
- the AS effect is based on the sequence-specific hybridization of the ' constructs by Watson-Crick base pairing with the target mRNA coding for the protein to be repressed, which leads to the prevention of protein synthesis via various mechanisms (Table 1).
- Tab. 1 AS effects and their mechanisms of action ss - "Single stranded" (single strand)
- AS-ON as therapeutic substances represents, in addition to various other application fields, a new promising therapy concept for oncological diseases [Tamm et al. ]. While conventional chemotherapy leads to non-specific inhibition of cell proliferation, AS therapy specifically inactivates those mRNAs that represent the molecular basis or an essential component of the degenerate, deregulated growth and tumor progression, and for the inhibition of the body's immune defense can be responsible.
- 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 in contrast to blood vessels of normal tissue, are permeable to substances in a size range between 4-10 kDa. This means that therapeutic AS-ON can specifically penetrate tumor blood vessels.
- Another advantage of these substances for example compared to antibodies that are almost exclusively active against extracellular proteins, is that, in principle, all proteins, both cytoplasmic and nucleus-localized as well as membrane-bound proteins, can be attacked via the respective target mRNA.
- the phosporthioat-AS-ON which is relatively resistant to a nuclease attack, is currently being evaluated in a number of clinical studies (phase I-III) with regard to its potential as anti-cancer therapeutics.
- Target mRNA molecules that are overexpressed in tumors are attacked.
- non-AS phosphothioate-ON
- a partial terminal modification of ON constructs offers increased stability in the extra- and intracellular milieu of the target cells (protection against degradation by exonucleases), especially when applied in vivo.
- a positive side effect that has been observed when using PS-ON is its immunostimulatory effect, which can support possible therapeutic success in some tumor applications.
- ribozymes As catalytically active RNA molecules, ribozymes are able to recognize cellular RNA structures as substrates and cleave them sequence-specifically at a phosphorus diester bond. The detection takes place via AS arms, which enable hybridization with the target mRNA due to complementary sequences. Compared to AS-ON, ribozymes have the fundamental advantage that a ribozyme molecule as a real catalyst has a large number of identical ones
- Ribozymes are already there effective in much lower concentration than ON and also lead to irreversible RNA degradation due to substrate cleavage [Sun et al. ].
- the hammerhead ribozyme (review: Birikh et al., 1997; Tanner, 1999) is particularly interesting for such applications because it can already be catalytically active as a comparatively small molecule (approx. 30-50 nucleotides).
- a very effective trans-cleaving hammerhead ribozyme consists, for example, of only 14 conserved nucleotides in the catalytic domain and two variable stem sequences (advantageously each of 6-8 nucleotides), which by Watson-Crick base pairing (analogous to AS-ON) Realize sequence-specific recognition of the substrate to be cleaved and then inactivate it by cleaving a phosphorus diester bond.
- a specific cleaving hammerhead ribozyme can be constructed against practically any RNA molecule that has a potential cleavage site with the minimal sequence requirement -NUX- and thus, for example, inhibit cellular mRNA or viral RNA.
- Other catalytic nucleic acids from DNA-yp e.g. DNAzyme
- DNAzyme can be used analogously.
- RNAi RNA interference
- siRNA small interference RNA
- the ' siRNA constructs are associated with specific cellular proteins, followed by the recognition of the target mRNA sequence due to the complementarity of the AS-si RNA strand.
- the intrinsic endonuclease activity of the ribonucleoprotein complex enables a specific degradation of the mRNA to be inhibited.
- the AS-ON is a PS-ON or a nucleic acid construct modified with further chemical changes.
- sequence region of the hTERT mRNA to which the polynucleotide is complementary is selected from the group comprising 2183-2205, 2206-2225, 2315-2334, 2317-2336, 2324-2346, 2331-2350 and / or 2333-2352.

- immobilization such as. for example, adsorption on 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 here through physical binding forces, often with the participation of hydrophobic interactions and ionic bonds.
- Such methods are advantageously easy to use and they influence the conformation of the polynucleotides only to a small extent.
- the binding can advantageously be improved by electrostatic binding forces between the charged groups of the polynucleotides and the carrier, for example by using ion exchangers such as Sephadex.
- Another method is covalent binding to carrier materials.
- the carriers can be reactive Have groups that form homopolar bonds with amino acid side chains.
