Abstract

The invention relates to a human Bcl-2 and human VEGF165 double-gene co-expression recombinant vector and a building method thereof, and is characterized in that IRES segment is utilized to connect an hBc1-2 gene and an hVEGF165 gene, and homologous recombination mechanisms in bacterium are utilized to recombine and build the human Bcl-2 and human VEGF165 double-gene co-expression recombinant vector according to an AdEasy system. The invention leads the Bcl-2 gene with anti-apoptosis capacity and the VEGF165 gene which currently promotes angiogenesis cytokine with strongest function to recombine on a same vector to be co-expressed, and solves the problem of low survival rate of transplanted cells under the condition of hypoxia and inflammation, simultaneously plays the function of promoting angiogenesis of VEGF165, plays an important part in the gene therapy of myocardial infarction and the cell transplantation research field, and has wide application prospect.

Description

technical field [0001] The present invention relates to a double-gene co-expression recombinant vector and its construction method, in particular to a kind of human Bcl-2 and human VEGF 165 Double-gene co-expression recombinant vector and its construction method. It belongs to the field of biological gene therapy. Background technique [0002] Myocardium infarction (MI) is a sharp reduction or interruption of coronary artery blood supply on the basis of coronary artery disease, resulting in severe and persistent myocardial ischemia and necrosis of the corresponding myocardium. Cardiomyocytes are terminally differentiated cells, which cannot be repaired by cell regeneration after myocardial injury, but form fibrotic scars. At present, the clinical treatment methods for MI are mainly drug therapy, coronary artery intervention and coronary artery bypass surgery. Although these three methods can recanalize the occluded blood vessels and restore blood perfusion in some patients...
