Definitions
- the present invention relates to a new method for the treatment of cancers. More particularly, it relates to a method of treating cancers by blocking cell proliferation which can be deregulated in tumor cells expressing an oncogen such as ras mutated or deficient for a tumor suppressor gene such as p53. It also relates to the use of gene therapy vectors making it possible to regulate it, as well as the pharmaceutical compositions containing them.
- p21 proteins The products of the ras genes, generally designated p21 proteins, play a key role in the control of cell division in all the eukaryotic organisms where they have been sought. Certain specific modifications of these proteins cause them to lose their normal control and lead them to become oncogenic. Thus, a large number of human tumors have been associated with the presence of modified ras genes. Likewise, overexpression of these p21 proteins can lead to disruption of cell proliferation.
- tumor suppressor genes like p53 and Rb.
- the protein p53 at least in its wild form, is a transcription factor which negatively regulates growth and cell division and which, in certain situations, is capable of inducing Tapoptosis (Yonish-Rouach et al., Nature, 352, 345-347, 1991).
- Tapoptosis Yamamoto-Rouach et al., Nature, 352, 345-347, 1991.
- p53 has been suggested to be a "guardian of the genome".
- certain phenomena can disrupt this mechanism of cellular self-regulation and thus favor the development of a neoplastic state.
- the present invention results precisely in part from the demonstration that the GAX protein constitutes a potential inhibitor of cell proliferation induced by ras proteins. It results in particular from the demonstration that a cell proliferation, deregulated in tumor cells, can be retao ⁇ ed by expressing the GAX protein there.
- the GAX protein is a protein of 303 amino acids. Its sequence has been characterized and its cDNA cloned (Gorski et al., Mol.Cell.Biol. 1993, 6, 3722-3733).
- the gax (growth arrest specifies homeobox) gene belongs to the family of homeotic genes. These genes code for transcriptional factors which contain consensus (or homeodomain) sequences recognizing specific regions of DNA (or homeoboxes) (review: Gehring et al. Cell, 78: 211-223, 1994).
- the rat gax protein iomeodomain is between amino acids 185 and 245. This gene has certain properties similar to the gas and Gadd genes since it also seems to control the G0 / G1 transition of the cell cycle.
- gax mRNA levels are reduced in rat CMLVs by a factor of 10 after two hours of exposure to PDGF (Gorski et al., Mol.Cell.Biol. 1993, 6, 3722-3733).
- the expression of the gax gene is therefore repressed during the mitogenic response of CMLV.
- the expression of the gax gene has been demonstrated in the cardiovascular system, in particular the heart and the aorta and so far the use in gene therapy of this gene has therefore been limited to the level of these cells, expressing it naturally.
- the Applicant has discovered that it is possible to advantageously enhance an inhibitory activity of the GAX protein with regard to cell proliferation in tumor cells, ie cells which do not express the gax gene endogenously.
- the present invention thus offers a new particularly effective approach for the treatment of tumors associated with a disruption of cell proliferation such as non-small cell lung tumors, pancreatic and colonic carcinomas, osteosarcomas, etc.
- the present invention also describes particularly effective systems enabling the delivery in vivo, directly into tumors, of such compounds and thus of combating the development of cancers.
- a first object of the invention therefore resides in the use of the GAX protein or a variant thereof for the preparation of a pharmaceutical composition intended for the treatment of cancers.
- variant designates any mutant, fragment or peptide having at least one biological property of GAX, as well as any GAX homolog obtained from other species.
- fragments and variants can be obtained by any technique known to those skilled in the art, and in particular by genetic and / or chemical and / or enzymatic modifications, or even by hybridization or by cloning by expression, allowing the selection of variants according to their biological activity. Genetic modifications include deletions, deletions, mutations, etc.
- the nucleic acid sequence used can code all or part of the rat GAX protein or one of its variants.
- the gene used within the meaning of the invention is preferably the gene coding for the GAX protein of rats or of its human counterpart. It is more preferably a cDNA or a gDNA.
- the claimed nucleic acid sequence can be injected as it is at the site to be treated, or incubated directly with the cells to be destroyed or treated. It has in fact been described that naked nucleic acids can penetrate cells without particular vector. Nevertheless, it is preferred in the context of the present invention to use an administration vector, making it possible to improve (i) the efficiency of cell penetration, (ii) targeting (iii) extra- and intracellular stability.
- D can be viral or non-viral vectors.
- the vector according to the invention can thus be a non-viral agent capable of promoting the transfer and expression of the nucleic sequence in prokaryotic or eukaryotic cells.
- Chemical or biochemical vectors represent an interesting alternative to natural viruses, in particular for reasons of convenience, safety and also by the absence of theoretical limit as regards the size of the DNA to be transfected.
- These synthetic vectors have two main functions, to compact the nucleic acid to be transfected and to promote its cellular fixation as well as its passage through the plasma membrane and, where appropriate, the two nuclear membranes. To compensate for the polyanionic nature of nucleic acids, the non-viral vectors all have polycationic charges.
- cationic polymers of polylysine type, (LKLK) n, (LKKL) n, polyethylene i ⁇ unine and DEAE dextran or else cationic lipids or lipofectants are the most advantageous. They have the property of condensing DNA and promoting its association with the cell membrane.
- the nucleic sequence used in the present invention can be formulated for topical, oral, parenteral, intranasal, intravenous, intramuscular, subcutaneous, intraocular, transdermal, etc. administration.
- it is used in an injectable form.
- It can therefore be mixed with any pharmaceutically acceptable vehicle for an injectable formulation, in particular for a direct injection at the site to be treated.
- They may in particular be sterile, isotonic solutions, or dry compositions, in particular lyophilized, which, by addition as appropriate of sterilized water or physiological saline, allow the constitution of injectable solutes.
- a direct injection of the nucleic sequence into the patient's tumor is advantageous because it allows the therapeutic effect to be concentrated in the affected tissues.
- the doses in nucleic sequence used can be adapted as a function of various parameters, and in particular as a function of the vector, the mode of administration used, the pathology concerned or even the duration of the treatment sought.
- adenoviruses it is thus possible to use adenoviruses, herpes viruses, retroviruses and more recently associated adeno viruses. These vectors are particularly effective in terms of transfection.
- a second object of the present invention therefore therefore is the use of a defective recombinant virus containing at least one inserted gene coding for all or part of the GAX protein or a variant thereof.
- the invention also resides in the use of such a virus for the treatment of cancers.
- the inserted and / or present gene may be a fragment of complementary DNA (AD Ne), of genomic DNA (gDNA), or a hybrid construct consisting for example of a cDNA into which would be inserted one or more introns. They can also be synthetic or semi-synthetic sequences.
- the inserted gene also includes sequences allowing its expression in the infected cell. These may be sequences which are naturally responsible for the expression of said gene when these sequences are capable of functioning in the infected cell. It can also be sequences of different origin (responsible for the expression of other proteins, or even synthetic). In particular, they may be sequences of eukaryotic or viral genes or derived sequences, stimulating or repressing the transcription of a gene in a specific way or not and in an inducible way or not.
- they may be promoter sequences originating from the genome of the cell which it is desired to infect, or from the genome of a virus, and in particular the promoters of the ElA genes, adenovirus MLP, the CMV promoter, LTR-RSV, etc.
- eukaryotic promoters include ubiquitous promoters (HPRT, vimentin, -actin, tubulin, etc.), promoters of intermediate filaments (desmin, neurofilaments, keratin, GFAP, etc.) promoters of therapeutic genes (MDR type, CFTR, factor VIII, etc.) tissue-specific promoters (smooth muscle cell actin promoter), promoters preferentially activated in dividing cells, or promoters responding to a stimulus (steroid hormone receptor, receptor retinoic acid, etc.).
- these expression sequences can be modified by adding activation, regulation sequences, etc.
- the inserted gene does not contain expression sequences, it can be inserted into the genome of the defective virus downstream of such a sequence.
- the inserted gene generally comprises, upstream of the coding sequence, a signal sequence directing the polypeptide synthesized in the secretory pathways of the target cell.
- This signal sequence may be the natural signal sequence of GAX, but it may also be any other functional signal sequence (that of the thymidine kinase gene for example), or an artificial signal sequence.
- the viruses according to the present invention are defective, that is to say incapable of replicating autonomously in the target cell.
- the genome of the defective viruses used in the context of the present invention is therefore devoid of at least the sequences necessary for the replication of said virus in the infected cell. These regions can be either eliminated (in whole or in part), or made non-functional, or substituted by other sequences and in particular by the inserted gene.
- the defective virus nevertheless retains the sequences of its genome which are necessary for the packaging of the viral particles.
- serotypes of adenoviruses there are different serotypes of adenoviruses, the structure and properties of which vary somewhat. Among these serotypes, it is preferred to use, within the framework of the present invention, human adenoviruses of type 2 or 5 (Ad 2 or Ad 5) or adenoviruses of animal origin (see application WO94 / 26914).
- adenoviruses of animal origin which can be used in the context of the present invention, mention may be made of adenoviruses of canine, bovine, murine origin (example: Mavl, Beard et al., Virology 75 (1990) 81), ovine, porcine , avian or even simian (example: after-sales service).
- the adenovirus of animal origin is a canine adenovirus, more preferably a CAV2 adenovirus [manhattan or A26 / 61 strain (ATCC VR- 800) for example].
- adenoviruses of human or canine or mixed origin are used.
- the defective adenoviruses of the invention comprise the
- the El region in the air is nor. foûct-ori-iclic.
- the viral gene writes can be rendered noncr.ctior.r.e! by any technique known to a person skilled in the art, and in particular by total suppression, substitution, partial deletion, or addition of one or more bases in the gene or genes considered. Such modifications can be obtained in vitro (on isolated DNA) or in situ, for example, by means of genetic engineering techniques, or by treatment with mutagenic agents.
- the adenovirus according to the invention comprises a deletion in the regions E1 and E4.
- it comprises a deletion in region E1 at which are inserted the region E4 and the sequence coding for -GAX (Cf FR94 13355).
- the deletion in the E1 region preferentially extends from nucleotides 455 to 3329 on the sequence of the adenovirus Ad5.
- the defective recombinant adenoviruses according to the invention can be prepared by any technique known to those skilled in the art (Levrero et al., Gene 101 (1991) 195, EP 185 573; Graham, EMBO J. 3 (1984) 2917). In particular, they can be prepared by homologous recombination between an adenovirus and a ponid plasmid, inter alia, the DNA sequence of interest. Homologous recombination occurs after co-transfection of said adenovirus and plasmid in an appropriate cell line.
- the cell line used must preferably (i) be transformable by said elements, and (ii), contain the sequences capable of complementing the part of the genome of the defective adenovirus, preferably in integrated form to avoid the risks of recombination.
- a line mention may be made of the human embryonic kidney line 293 (Graham et al., J. Gen. Virol. 36 (1977) 59) which contains in particular, integrated into its genome, the left part of the genome an Ad5 adenovirus (12%) or lines capable of complementing the El and E4 as described in particular in applications No. WO 94/26914 and WO95 / 02697.
- the adenoviruses which have multiplied are recovered and purified according to conventional techniques of molecular biology.
- AAV adeno-associated viruses
- D comprises approximately 4700 bases, and contains at each end an inverted repeat region (ITR) of approximately 145 bases, serving as the replication origin for the virus.
- ITR inverted repeat region
- the rest of the genome is divided into 2 essential regions carrying the packaging functions: the left part of the genome, which contains the rep gene involved in viral replication and the expression of viral genes; the right part of the genome, which contains the cap gene coding for the capsid proteins of the virus.
- the defective recombinant AAVs according to the invention can be prepared by co-transfection, in a cell line infected with a human helper virus (for example an adenovirus), of a plasmid containing the nucleic sequence of interest bordered by two inverted repeat regions (ITR) from AAV, and a plasmid carrying the packaging genes (rep and cap genes) from AAV.
- a human helper virus for example an adenovirus
- ITR inverted repeat regions
- rep and cap genes packaging genes
- the invention also relates to a plasmid comprising a sequence coding for GAX bordered by two ITRs of an AAV.
- a plasmid can be used as it is for transferring the GAX sequence, optionally incorporated into a liposomal vector (pseudovirus).
- pseudovirus a liposomal vector
- retroviruses the construction of recombinant vectors has been widely described in the literature: see in particular EP 453242, EPI 78220, Bemstein et al. Broom. Eng. 7 (1985) 235; McCormick, BioTechnology 3 (1985) 689, etc.
- retroviruses are integrative viruses, infecting dividing cells.
- the genome of retroviruses essentially comprises two LTRs, an encapsidation sequence and three coding regions (gag, pol and env).
- the gag, pol and env genes are generally deleted, in whole or in part, and replaced by a heterologous nucleic acid sequence of interest.
- These vectors can be produced from different types of retroviruses such as in particular MoMuLV ("murine moloney leukemia virus”; also designated MoMLV), MSV ("murine moloney sarcoma virus”), HaSV ("harvey sarcoma virus”) ; SNV ("spleen necrosis virus”); RSV ("rous sarcoma virus”) or the Friend virus.
- MoMuLV murine moloney leukemia virus
- MSV murine moloney sarcoma virus
- HaSV human moloney sarcoma virus
- SNV spleen necrosis virus
- RSV rous sarcoma virus
- Friend virus Friend virus
- a plasmid comprising in particular the LTRs, the encapsidation sequence and said coding sequence is generally constructed, then used to transfect a cell line called encapsidation, capable of '' bring in trans retroviral functions deficient in the plasmid.
- the packaging lines are therefore capable of expressing the gag, pol and env genes.
- Such packaging lines have been described in the prior art, and in particular the line PA317 (US4,861,719); the PsiCRTP line (WO90 / 02806) and the GP + envAm-12 line (WO89 / 07150).
- the recombinant retroviruses may include modifications at the level of the LTRs to suppress transcriptional activity, as well as extended packaging sequences, comprising a part of the gag gene (Bender et al., J. Virol. 61 (1987) 1639).
- the recombinant retroviruses produced are then purified by conventional techniques.
- a defective recombinant adenovirus For the treatment of cancers, it is particularly advantageous to use a defective recombinant adenovirus. It is possible to use relatively small amounts of active principle (recombinant adenovirus), and also allows an effective and very rapid action on the sites to be treated.
- the adenoviruses of the invention are also capable of expressing the introduced gax gene at high levels, which gives them a very effective therapeutic action.
- the adenoviruses of the invention have a limited persistence in proliferative cells and therefore a transient effect perfectly suited to the desired therapeutic effect.
- the doses of virus used for the injection can be adapted according to various parameters, and in particular according to the mode of administration used and the duration of the treatment sought.
- the recombinant viruses according to the invention are formulated and administered in the form of doses of between 10 ⁇ and 10 14 pfu / ml.
- doses of 10 6 to 10 * 0 pfu / ml can also be used.
- pfu plaque forming unit
- the term pfu corresponds to the infectious power of a suspension of virions, and is determined by infection of an appropriate cell culture, and measures, generally after 48 hours, the number of plaques of infected cells. The techniques for determining the pfu titer of a viral solution are well documented in the literature.
- the present invention is advantageously used in vivo for the destruction of cells in hyperproliferation (i.e. in abnormal proliferation).
- cancers in which an activated oncogen is involved.
- colon adenocarcinomas thyroid cancer
- lung carcinoma myeloid leukemia
- colorectal cancer breast cancer
- lung cancer gastric cancer
- cancer esophagus B lymphomas
- ovarian cancers bladder cancers
- glioblastomas etc.
- this treatment can concern both humans and any animal such as sheep, cattle, domestic animals (dogs, cats, etc.), chevaax, fish, etc.

- the plasmids of the pBR322, pUC type and the phages of the Ml 3 series are of commercial origin (Bethesda Research Laboratories).
- the DNA fragments can be separated according to their size by electrophoresis in agarose or acrylamide gels, extracted with phenol or with a phenol / chloroform mixture, precipitated with ethanol and then incubated in the presence of the DNA ligase from phage T4 (Biolabs) according to the supplier's recommendations.
- the filling of the protruding 5 ′ ends can be carried out by the Klenow fragment of DNA Polymerase I of E. coli ( Biolabs) according to the supplier's specifications.
- the destruction of the protruding 3 ′ ends is carried out in the presence of the DNA polymerase of phage T4 (Biolabs) used according to the manufacturer's recommendations.
- the destruction of the protruding 5 ′ ends is carried out by gentle treatment with nuclease SI.
- Mutagenesis directed in vitro by synthetic oligodeoxynucleotides can be carried out according to the method developed by Taylor et al. [Nucleic Acids Res. Jj (1985) 8749-8764] using the kit distributed by Amersham.
- Enzymatic amplification of DNA fragments by the so-called PCR technique can be performed using a "DNA thermal cycler" (Perkin Elmer Cetus) according to the specifications of the manufacturer- Verification of the nucleotide sequences can be carried out by the method developed by Sanger et al. [Proc. Natl. Acad. Sci. USA, 74 (1977) 5463-5477] using the kit distributed by Amersham.
- EXAMPLE 1 Constellation of the vector pXL-CMV-Gax iiA carrying the gene coding for the rat gax protein under the control of the CMY promoter.
- This example describes the construction of a vector containing the cDNA coding for the protein gax (species: rat) and adenoviral sequences allowing a recombination.
- the influenza virus hemagglutinin epitope (HAI epitope), comprising 18 amino acids, is added to the N-terminus of the gax protein (Field et al., Mol.CelLBiol. 8: 2159-2165, 1988 ).
- This epitope addition process makes it possible to follow, in particular by immunofluorescence techniques, the expression of gax using antibodies directed against the HAI epitope. In addition to its sensitivity, this method eliminates the background noise corresponding to the expression of endogenous gax proteins both in vitro and in vivo.
- the EcoRI-Xbal fragment corresponding to the left end of the genome of the Ad5 adenovirus was first cloned between the EcoRI and Xbal sites of the vector pIC19H. This generates the plasmid pCA.
- the plasmid pCA was then cut by Hinfl, its prominent 5 'ends were filled with the klenow fragment of DNA polymerase I from E. coli, then it was cut by EcoRI.
- the fragment thus generated of the plasmid pCA which contains the left end of the genome of the adenovirus Ad5 was then cloned between the EcoRI and Smal sites of the vector pIC20H (Marsh et al., Gene 22 (1984) 481).
- the plasmid pCB was then cut with EcoRI, its prominent 5 'ends were filled in with the klenow fragment of DNA polymerase I from E. coli, then it was cut with BamHI.
- the fragment thus generated of the plasmid pCB which contains the left end of the genome of the adenovirus Ad5 was then cloned between the NruI and Bgi ⁇ sites of the vector pIC20H. This generates the plasmid pCE, an interesting characteristic of which is that it has the first 382 base pairs of the adenovirus Ad5 followed by a cloning multisite.
- the Sall-Taql fragment of the plasmid pPY53 prepared from a dam- context, containing the part of the Ad5 radenovirus genome between the Sau3A (3346) and Taql (5207) sites was then cloned between the SalI and Clal sites of the vector pIC20H, which generates the plasmid pCA '.
- the Taql (5207) - Narl (5519) fragment of the Ad5 adenovirus genome prepared from a dam context and the Sall-Taql fragment of the plasmid pCA ' were then ligated and cloned between the SalI and Narl sites of the vector pIC20H.
- the Gax cDNA was cloned between the Xbal-BamHI sites of the pCGN vector (Tanaka and Herr, Cell 60: 375-386, 1990).
- the resulting pGCN-Gax vector contains the early promoter and enhancer sequence of cytomegalovirus (CMV) (-522, +72; Boshart et al, Cell, 41: 521-530, 1985), the thymidine kinase leader sequence of Herpes simplex virus including the initiation codon AUG as well as the first three amino acids (+55, +104; Rusconi and Yamamoto, EMBO J., 6: 1309-1315, 1987), the sequence coding for the HAI epitope, the rat gax cDNA and finally the poly adenylation sequence of the rabbit ⁇ -globin gene (Pabo et al, cell. 35: 445-453, 1983).
- CMV cytomegalovirus
- the vector pCGN-Gax was then cut with Xmnl and Sfil and the fragment obtained, containing promoter, cDNA and polyadenylation sequence, previously treated with Klenow, was introduced into the EcoRV site of the shuttle vector pCOl containing the adenoviral sequences necessary for recombination.
- the plasmid obtained was designated pXL-CMV-Gax HA ( ⁇ * Figure 2).
- the vector pXL-CMV-Gax HA prepared in Example 1 is then linearized and cotransfected for recombination with a deficient adenoviral vector, in helper cells (line 293) providing in trans the functions coded by the El regions (ElA and EIB ) of adenovirus.
- the Ad-CMVgax adenovirus was obtained by homologous recombination in vivo between the Ad.RSVJ3gal adenovirus (Stratford-Perricaudet et al., J. Clin. Invest 90 (1992) 626) and the vector pXL-CMV-Gax HA sei ⁇ e is following protocol: vector pXL- CMV-Gax HA linearized with the enzyme XmnI, and the adenovirus Ad.RSVBgal linearized with ClaI are cotransfected into line 293 in the presence of calcium phosphate to permit homologous recombination . The recombinant adenoviruses thus generated were selected by plaque purification.
- the recombinant adenovirus is amplified in the cell line 293, which leads to a culture supernatant containing the unpurified recombinant defective adenovirus having a titer of approximately l ⁇ ! 0 pfu / ml.
- the viral particles are purified by centrifugation on a cesium chloride gradient according to known techniques (see in particular Graham et al., Virology 52 (1973) 456).
- the Ad-CMVgax adenovirus is stored at -80 ° C in 10% glycerol.
- Example 3 Control of the expression of Ad-CMVgax in human tumor cells H460.
- Human H460 tumor cells derived from non-small cell lung cancer were transduced by the recombinant adenovirus Ad-CMV gax and by a control virus expressing ⁇ -galactosidase (Ad-RSV- ⁇ gal) with multiplicities of infection (ME) increasing (Figure 3). After 1 hour 30 minutes incubation in the presence of the adenoviral solution, the culture medium comprising 10% fetal serum was renewed and the cells incubated for a period of 48 hours. The cell viability being checked by trypan blue exclusion test, the number of viable cells per culture well is then determined. Two batches of AdCMV gax adenovirus, Ad-gax and Ad-gax (2), were used and correspond to two productions independent in 293 cells. The activities of the two batches appear to be comparable and very distinct from the AdRSV ⁇ gal control adenovirus.
- Ad-RSV - ⁇ gal has previously made it possible to demonstrate the capacity of a recombinant adenovirus to efficiently transduce H460 cells.
- nuclear ⁇ gal activity has been detected in more than 75% of cells treated with Ad-RSV- ⁇ gal (M.O.I. 1000).
- Ad-RSV- ⁇ gal M.O.I. 1000
- the expression of the gax protein was demonstrated in the cells transduced by Ad-CMV gax by immunofluorescerce.
- the transduction efficiencies of the Ad-CMV gax and Ad-RSV- ⁇ gal viruses were found to be comparable.
- the treatment of H460 cells with Ad-CMV gax is associated with a reduction in cell proliferation but also with massive cytotoxicity detected 48 hours after transduction by the adenovirus (cf. FIGS.
- H358 cells also derived from lung carcinoma non-small cell, is a deficiency model for the p53 protein.
- This cell line indeed has a homozygous deletion for the p53 gene (Maxwell and Roth. Oncogen 8: 3421. 1993).
- the Ad-gax adenovirus effectively blocks the growth of H358 cells and causes massive cytotoxicity 48 hours after adenoviral transduction (FIG. 5). This my cell is not detected in the presence of an adenovirus controlling Ad-RSV- ⁇ gal.
- Gax can advantageously be associated with a therapeutic benefit in the cancer patient.
