Embodiment Construction

[0036] Figure 1 to Figure 13 Shown are examples of siRNA, siRNA plasmid, interfering lentivirus and its construction method and application for targeting and inhibiting Mus81 gene expression of the present invention. By designing the siRNA sequence of the human Mus81 gene and constructing the corresponding siRNA plasmid and interfering lentivirus, The method of lentivirus-mediated siRNA is used to specifically inhibit the expression of Mus81 gene in liver cancer cells, so as to realize the effects of inhibiting the growth and proliferation of liver cancer cells, promoting their apoptosis and improving their chemosensitivity.

[0037] 1. Design the siRNA sequence targeting to inhibit the expression of Mus81 gene

[0038] Firstly, the sequence of the human Mus81 gene (BC009999) was obtained from Genebank, and then three siRNA sequences targeting the Mus81 gene were designed using the design software Genechem of Shanghai Jikai Gene Chemical Technology Co., Ltd., and the siRNA se...

Abstract

The invention discloses siRNA for targeted inhibition of Mus81 gene expression, siRNA plasmid, interfering lentivirus and a construction method and application thereof; a siRNA sequence of human Mus81 gene is designed, the corresponding siRNA plasmid and interfering lentivirus are constructed, lentivirus mediation siRNA method is used for specific inhibition of Mus81 gene expression in hepatoma carcinoma cells so as to realize the effects of inhibition of hepatoma carcinoma cell growth proliferation, promotion of hepatoma carcinoma cell apoptosis and improvement of hepatoma carcinoma cell chemosensitivity, and other various aspects, the Mus81 gene which is a very effective drug target for treatment of liver cancer is provided, and the siRNA has great significance to preparation of Mus81 gene-targeted treatment drugs of the liver cancer.

Description

technical field [0001] The invention relates to the technical field of genetic engineering, in particular to siRNA, siRNA plasmid, interfering lentivirus and its construction method for targeting and inhibiting the expression of Mus81 gene, and its application in the preparation of drugs for treating liver cancer. Background technique [0002] The Mus81 gene belongs to the XPF endonuclease superfamily. It was first identified in yeast by Interthal H et al. in 2000. Because the yeast knocked out of this gene is more sensitive to ethanesulfonate and ultraviolet rays, Interthal H et al. for "Ethane Sulfonate and UV Sensitive to Independent Sequence No. 81" ( M MS and U V s sensitive isolate number 81 , Mus81). Chen XB et al subsequently identified the human Mus81 gene in 2001, which is located on the long arm of human chromosome 11 (11q13.1), contains 16 exons, and the encoded Mus81 protein has two DNA molecules Combined helix-hairpin-helix structure with a typical XPF-lik...
