Abstract

The invention discloses an IL-2 and MART-1 dual-gene co-expression recombinant vector, which is sequentially linked with an IL-2 gene, an IRES sequence and an MART-1 gene in a vector transcription direction, or is sequentially linked with an MART-1 gene, an IRES sequence and an IL-2 gene in a vector transcription direction, wherein nucleotide sequence of the IL-2 gene is represented in SEQ ID NO: 1 in a sequence list, nucleotide sequence of the MART-1 gene is represented in SEQ ID NO: 2 in the sequence list, and nucleotide sequence of the IRES sequence is represented in SEQ ID NO: 3 in the sequence list. The dual-gene co-expression recombinant vector, which links the IL-2 gene and the MART-1 gene through the IRES sequence, can simultaneously express a human melanin differentiation antigen and interleukin-2; the recombinant vector, in immunogene therapy of melanin, not only can develop an immune regulating function of a cell factor but also can generate a specific anti-tumor effect aiming at the melanin.

Description

technical field

[0001] The invention relates to a recombinant vector and its preparation method and application, in particular to a double-gene co-expression recombinant vector and its preparation method and application. Background technique

[0002] Melanoma (Melanoma), also known as malignant melanoma (Malignant Melanoma, MM), is a malignant tumor derived from neural crest melanocytes. It is a malignant tumor with the highest mortality rate among surface tumors. In recent years, the incidence and corresponding mortality of melanoma are increasing rapidly, and the age of onset is getting earlier and earlier, which seriously threatens human health.

[0003] The traditional treatment of melanoma is a comprehensive treatment including surgery, chemotherapy, and immunotherapy. At present, the only effective treatment method is surgical resection of the tumor when the tumor thickness is less than 1 mm, but due to the high degree of invasion and metastasis of melanoma and resis...
