Objective:This study aims to prepare a human anti-c-Met full-molecule antibody(c-Met-IgG1)conjugated with recombinant analgesic-antitumor peptide(rAGAP) to analyze their biological characteristics and detect their effects on the biological behavior of ovarian cancer cells. Methods:Using the human anti-c-Met antibody gene stored in our laboratory as a template,construct the c-Met-IgG1-rAGAP eukaryotic expression vector was constructed and transfected it into eukaryotic cells to obtain the antibody conjugate. The immunological properties of c-Met-IgG1 and c-Met-IgG1-rAGAP were evaluated by methods such as affinity detection,immunofluorescence,and flow cytometry. CCK-8,scratch test,and Transwell invasion test were used to detect the effects of antibodies on the proliferation,migration and invasion of ovarian cancer cells. Results:Two antibodies,c-Met-IgG1 and c-Met-IgG1-rAGAP,which can specifically bind to c-Met protein,were successfully prepared;c-Met-IgG1 and c-Met-IgG1-rAGAP proved in a series of experiments can inhibit the proliferation,migration and invasion of the c-Met-positive ovarian cancer cell HO8910,and the inhibitory effect of c-Met-IgG1-rAGAP on ovarian cancer cells is higher than that of c-Met-IgG1,while these effects were not observed in the c-Met-negative IOSE386 cells. Conclusion:The research results show that c-Met-IgG1-rAGAP can target c-Met-positive ovarian cancer cells and has anti-tumor activity,which can lay a research foundation for exploring molecular targeted treatment of ovarian cancer.
