Effect of Apatinib on Invasion and Migration of Lung Cancer Cells and Its Mechanism / 中国肺癌杂志

ABSTRACT

BACKGROUND@#Lung cancer is one of the most deadly cancers in the world for human. In recent years, the effect of targeted therapy has become increasingly significant. Apatinib is a multi-target anti-tumor drug that is currently under study. The purpose of this study is to investigate the effects of Apatinib on the biological characteristics of lung cancer cells and its possible mechanism.@*METHODS@#Lung cancer cell lines H1299 and H3255 were cultured in vitro. The effects of Apatinib on proliferation, migration and invasion of H1299 and H3255 cells were detected by cell proliferation assays wound healing assays and Transwell assays. The protein expression related to cancer angiogenesis and invasion was detected by Western blot.@*RESULTS@#Apatinib significantly inhibited the proliferation, migration and invasion of H1299 and H3255 in a concentration-dependent manner. Western blot showed that with the increasing of drug concentration, VEGF, VEGFR2, N-cadherin, MMP9, MMP2 and Vimentin were down-regulated, and E-cadherin were up-regulated.@*CONCLUSIONS@#Apatinib can inhibit the invasion and migration of lung adenocarcinoma cells H1299 and H3255. By regulation of epithelial-mesenchymal transition and the expression of matrix metalloproteinase-related proteins.
