Definitions
- the invention relates to a transgenic non-human mammal, a method for its production, its use, cell tissue therefrom, a method for the production of such cell tissue, its use, a recombinant DNA expression vector and the use of this vector.
- non-human mammals refers to taxonomically higher units than animal species.
- Transgenic animals are organisms that carry an additional, non-native gene in their genome. Within the scope of the invention, in particular, those transgenic animals are meant which also have the foreign gene in the germ cells and which therefore pass on the foreign gene vertically, ie from generation to generation. If a special transgenic animal is thus created, further corresponding transgenic animals can be obtained by breeding.
- Various forms of transgenic animals are known and various processes for producing transgenic animals are also known.
- the expression cell tissue encompasses complete organs or parts of organs of an animal, but also very specific cell lines, which can be isolated and cultivated, ie multiplied therefrom.
- a recombinant DNA expression vector is an instrument for producing a transgenic animal which carries, among other things, the foreign DNA which is to be introduced into the animal's cells.
- Cancer can often be attributed to the effects of so-called oncoproteins. These are proteins that are structurally changed compared to corresponding proteins in the healthy organism. These oncoproteins are able to convert normal cells into uncontrolled proliferating cells, ie cancer cells, via processes that have not yet been fully elucidated. convert. The formation of oncoproteins in an organism is in turn due to so-called oncogenes, ie genes that code for the oncoprotein. Oncogenes can be introduced into a cell via viruses, but can also be formed by mutating (certain) "healthy" genes, the proto-oncogenes.
- Such mutations can result, for example, by translocation (shift) of a gene responsible for the production of a protein within the genome, by point mutations (replacement of a base and / or individual bases in the DNA of a gene responsible for the production of a protein for a different base, with the result the formation of a protein with a modified amino acid sequence, the oncogene), by deletion (removal of one or more bases) or by mutations in the region of a so-called promoter responsible for the gene in question.
- a promoter is a DNA region of a gene that can be used to control the transcription (transcription of the DNA code into a corresponding RNA) and thus ultimately the expression (formation) of the protein correlated with the gene.
- each gene is naturally assigned a specific promoter, which is upstream of this in the genome. Upstream means that the promoter is arranged in the DNA sequence at a certain distance from the starting point of a transcription. To initiate a transcription, however, it is then also necessary that so-called - often cell type-specific - transcription factors attach to the promoter.
- the so-called Raf proto-oncogenes play a special role, particularly in connection with lung cancer.
- These genes are evolutionarily highly conservative and encode serine / threonine-specific cytoplasmic kinases, which in turn play a role in mitogenic signal transduction.
- Genes A, B and c-Raf-1 are known.
- the family of the Raf genes includes the c-Raf-1 gene, which ubiquitously expresses the c-Raf-1 kinase in an organism.
- the c-Raf-1 gene has 3 conserved regions, ie these regions match the corresponding regions of other Raf genes in the family.
- the region CR1 is a regulatory domain around a Cys Finger consensus sequence
- the region CR2 is a region with a high content of serine or threonine
- CR3 is the kinase domain.
- 5,156,841 discloses plasmids and eukaryotic expression vectors which contain A-Raf and v-Raf oncogenes, but in other contexts, namely the genetic engineering of Raf oncoproteins or the in vivo production of Raf oncoproteins as part of immunological tests.
- the invention is based on the technical problem of making available non-human mammals in a sufficiently large number and with pathology of the same type and reproducible with regard to tumor formation for the purpose of carrying out preclinical studies on prospective anti-cancer active substances or therapies.
- the invention teaches a transgenic non-human mammal, the cells of which are characterized by a constitutively active oncogenic mutant of the kinase domain of the c-Raf-1 gene or by a corresponding normal allele or derivative of the A, B, or c-Raf-1 gene expressing encoded protein.
- constitutively active means in the context of the invention that the protein as such is always active, that is to say that the physiological effect of the protein always occurs in a cell or the organism even without the requirement of further reaction cascades.
- the activation of the non-constitutively active Raf-1 protein requires, for example, the binding of the Ras protein to the Raf-1 protein.
- the expression constitutively active in the context of the invention consequently only refers to the protein or the corresponding gene code and not to the gene itself or the gene activation.
- the reference to the Raf-1 gene means Raf-1 genes, or variants thereof, which occur in any organism, or at least those which occur in mammals. Because the mammal is a transgenic animal with the properties mentioned, the pathology of the tumors induced by the expression of the mutant can be of the same type Animals can be obtained in virtually any number by natural reproduction from a transgenic parent. This enables preclinical investigations of active substances or therapies to be carried out with the required reproducibility and with the required statistical significance, even with defined control groups.
- the expression of the kinase domain of the Raf-1 gene constituted by the constitutively active oncogenic mutant or by a corresponding allele or derivative of the A, B or c -Raf-1 gene encoded protein takes place in lung cells, because then the animals reproducibly develop lung tumors.
- a mammal identified above is characterized by having foreign DNA with a constitutively active oncogenic mutant of the kinase domain of the Raf-1 gene or with a corresponding normal allele or derivative of the A, B or c-Raf-1- Contains genes. Alleles or derivatives are variants in a DNA sequence that practically do not influence the basic function of the gene in question.
- the foreign DNA advantageously additionally contains a promoter for the surfactant protein C, preferably for the human surfactant protein C, and this promoter is arranged in the foreign DNA with the proviso that the transcription by the promoter the mutant of the kinase domain of the Raf-1 gene or a corresponding normal allele or derivative of the A, B or c-Raf-1 gene is controlled.
- the promoter which is naturally upstream of the gene coding for the surfactant protein C, is instead upstream of the mutant or gene according to the invention at a suitable point.
- the exact arrangement of promoter and mutant or gene to each other lies in the skill of the average specialist.
- the surfactant protein C plays a role in the context of the surfactant factor, which reduces the alveolar surface tension between the pulmonary epithelium and the air and thus ultimately prevents the alveoli from collapsing when exhaling and the epithelia from sticking together.
- the foreign DNA additionally contains DNA of the SV40 virus.
- SV stands for Simian Virus. This includes in detail the polyadenylation sequence and intron / exon regions of the SV40 virus which are known (see description of the following FIG. 1). The incorporation of this SV40 DNA increases the translation efficiency of the polyadenylated mRNA. In particular, it is preferred if the mammal is one of the rodents.
- a transgenic non-human mammal which is explained in more detail above, can be obtained by the following process steps: a) Incorporation of the cDNA sequence of a constitutively active oncogenic mutant of the kinase domain of the Raf-1 gene or a corresponding normal allele or derivative of A, B or c-Raf-1 gene in an expression vector, b) introduction of the transgene vector obtained in step a), preferably after linearization, into pronuclei of fertilized oocytes from a non-human mammal, c) implantation of the in step b) oocytes obtained in ammentants of the same species as the donor species of the oocytes and discharge of subsequent comments from the oocytes, d) genotyping and selection of those obtained in step c)
- cells of the selected mammals contain a by the constitutively active oncogenic mutant of the kinase domain of the Raf-1 gene or by a corresponding normal allele or derivative of the A, B or c-Raf-1 -Gens express the encoded protein.
- the genotyping can be carried out using methods well known to the person skilled in the art, for example after tail tip biopsy by means of PCR (polymerase chain reaction, a method for in-vitro amplification of a defined DNA fragment) and Southern blot (a method for analyzing DNA fragments in DNA preparations), in which case those
- Mammals are selected, the cells of which, according to the genotyping studies, contain the foreign DNA according to the invention.
- the expression vector used in stage a) advantageously contains a promoter for the surfactant protein C, preferably a promoter for the human surfactant protein C.
- This promoter is arranged in the foreign DNA with the proviso that the transcription of the mutant of the kinase by the promoter Domain of the Raf-1 gene or a corresponding normal Aliei or derivative of the A, B or c-Raf-1 gene is controlled.
- the foreign DNA can have, for example, either the healthy (FIG. 1) or a constitutively active oncogenic mutant of the Raf-1 gene with a sequence according to one of FIG.
- point mutations of the sequence shown in FIG. 1 can also be used. Such point mutations can be caused, for example, by administering 1-ethyl-1-nitrosourea (ENU) to animals with the healthy sequence, which makes such mutants easily accessible.
- ENU 1-ethyl-1-nitrosourea
- the invention also relates to a method for producing a transgenic, non-human mammal as described above according to claims 10 and 11.
- Non-human mammals according to the invention are used for the preclinical examination of the effectiveness of substances directed against lung carcinomas and / or of therapeutic methods directed against lung carcinomas, in particular for the preclinical examination of the effectiveness of Raf kinase inhibiting substances.
- Such substances completely inhibit or reduce the activity of Raf kinases, with which it may be possible to find a means for deactivating Raf oncoproteins in particular and consequently for inhibiting the proliferation of tumor cells.
- Another advantageous use of a non-human mammal according to the invention is to study the pathogenesis of lung tumors, which also enables a better understanding of the disease as such.

- mice according to the invention of both lines developed massive lung carcinomas at the age of 6 to 7 months, the cellular origin of which corresponds to type II pneumocytes according to the distribution pattern and phenotype. Examination of the time dependence of the tumor development showed that clear multicentre tumor formation was present after only 2 months. Expression of the transgene in the Western blot could also be detected in the lung tissue of both lines, as can be seen from FIG. 3. This also proves a correlation between deliberately misdirected Raf kinase activity and lung tumor induction in vivo.
