摘 要：Objective: To study the effect of lentivirus-mediated integrin αVβ3-sh RNA on tumor growth of mice with lung cancer xenograft. Methods: Lung cancer tissue, paracancer tissue and normal tissue were collected and integrin αVβ3 expression was detected; BALB/c nude mice were selected, divided into integrin αVβ3 knockdown group(KD group) and negative control group(NC group), and inoculated with cells stably infected by integrin αVβ3-sh RNA lentivirus and cells stably infected by negative control-sh RNA lentivirus respectively, the growth of tumor tissue was continuously observed, and the number of apoptosis cells as well as the expression of angiogenesis, apoptosis and invasion genes in tumor tissue were detected. Results: m RNA content and protein content of integrin αVβ3 in lung cancer tissue were significantly higher than those in paracancer tissue and normal tissue; increasing trend of tumor tissue volume of KD group was weaker than that of NC group, and tumor volume at various points in time of KD group was lower than that of NC group; m RNA contents and protein contents of VEGF, FGF, EGF, Bcl-2, MMP-9, MMP-12 and MMP-13 in tumor tissue of KD group were lower than those of NC group, and apoptosis index as well as m RNA content and protein content of Bax were higher than those of NC group. Conclusions: The expression of integrin αVβ3 increases in lung cancer tissue, and lentivirus-mediated integrin αVβ3-sh RNA can inhibit tumor growth of mice with lung cancer xenografts.
