Abstract: The invention refers to genetic engineering and can be used in biotechnology, medicine, and agriculture for the manufacture of gene therapy products. A gene therapy DNA vector based on the VTvaf17 gene therapy DNA vector is proposed that carries a target gene selected from the group of SHH, CTNNB1, NOG, WNT7A genes for the treatment of diseases characterized by impaired tissue regeneration, wound healing, growth, pigmentation and hair coloring, formation and maturation of hair follicles, processes of differentiation and growth of cells, leading to a decrease in the activity of hair follicles, including with allopecia, autoimmune diseases, hereditary and acquired pathological conditions thawing, and for accelerated healing of wounds, restoration of the hairline and the prevention and inhibition of alopecia. Moreover, the gene therapy DNA vector VTvaf17-SHH, or VTvaf 17 -CTNNB 1, or VTvaf17-NOG, or VTvaf17-WNT7A has the nucleotide sequence of SEQ ID No. 1 or SEQ ID No. 2 or SEQ ID No. 3 or SEQ ID No.

Abstract: Produced the gene therapy DNA vectors based on the gene therapy DNA vector for treatment of diseases associated with disorders of osteogenesis, formation and regeneration of bone and cartilage tissues, including, in case of bone fractures, increased brittleness of bones, reduction of bones mineralisation, for improvement in osteoinduction of bone implants. The gene therapy DNA vector contains the coding region of the COL1A1, COL1A2, BMP2 or BMP7 therapeutic genes. Methods of producing or use the gene therapy DNA vector carrying therapeutic genes. Escherichia coli strain SCS110-AF/VTvaf17-COL1A1, SCS110-AF/VTvaf17-COL1A2, SCS110-AF/VTvaf17-BMP2 or SCS110-AF/VTvaf17-BMP7 obtains by the method described above carrying gene therapy DNA vector VTvaf17-COL1A1, VTvaf17-COL1A2, VTvaf17-BMP2 or VTvaf17-BMP7. The method of producing the gene therapy DNA vector carrying COL1A1, or COL1A2, or BMP2, or BMP7 therapeutic gene uses on an industrial scale.

Abstract: Gene-therapeutic DNA vectors based on the VTvaf17 gene-therapeutic DNA vector have been created for the treatment of diseases characterized by impaired mucociliary transport and mucolytic function and the development of mucostasis, including cystic fibrosis. The gene therapy DNA vector contains the coding region of the CFTR therapeutic gene, or the NOS1 therapeutic gene, or the AQ1 therapeutic gene, or the AQ3 therapeutic gene, or the AQ5 therapeutic gene. Methods for their preparation or use are proposed, as well as strains for the production of a gene therapy vector.

Abstract: Disclosed is a gene therapy DNA vector VTvaf17 for genetic modification of animal and human cells having SEQ ID No. 1, and methods for its synthesis, involving constructing vectors containing a promoter region of human elongation factor EF1A, a polylinker with sites for restriction endonucleases, a transcription terminator, a polyadenylation sequence of human growth factor, a regulatory element of transposon Tn10 allowing for antibiotic-free positive selection, an origin of replication, and a kanamycin resistance gene. Escherichia coli strain SCS110-AF is also provided by the present invention. The method for creating the strain involves constructing a linear DNA fragment containing regulatory element of transposon Tn10, a levansucrase gene, sacB, a chloramphenicol resistance gene, and two homologous sequences. The E. coli cells are transformed by electroporation and clones surviving chloramphenicol are chosen.
