ABSTRACT
BACKGROUND@#Lung cancer is the most common malignancy world-wide. Small cell lung cancer is the deadliest subtype of lung cancer, which features such as rapid growth, early metastasis, and high vascularization. Apatinib is a vascular endothelial growth factor receptor 2 inhibitor independently developed in China, which has a significant inhibition in a variety of solid tumors. The purpose of this study is to investigate the effects of Apatinib alone or Apatinib combined with mammalian target of rapamycin (mTOR) inhibitor, CCI-779, on small cell lung cancer cell line NCI-H446 in vitro.@*METHODS@#The small cell lung cancer cell line NCI-H446 was grew in vitro. The effects of Apatinib alone or Apatinib combined with CCI-779 on proliferation, apoptosis, cell cycle and migration of NCI-H446 small cell lung cancer cells were detected by CCK8; FACS and transwell assays were also carried out; Western blot assays were used to detect vascular endothelial growth factor and cell cycle related protein expression.@*RESULTS@#CCK8 assays showed that high concentration of Apatinib could inhibit the proliferation of NCI-H446 cells. Apoptosis assays showed that high concentration of Apatinib could induce NCI-H446 cell apoptosis. Transwell assays showed that high concentration of Apatinib could inhibit NCI-H446 cell migration. After combined with mTOR inhibitor CCI-779, low concentration of Apatinib could inhibit the proliferation and migration of NCI-H446 small cell lung cancer cells and induce apoptosis.@*CONCLUSIONS@#Apatinib has a concentration-dependent effect on the small cell lung cancer cell line NCI-H446. High concentration of Apatinib can inhibit the proliferation and migration of NCI-H446 small cell lung cancer cells, induce apoptosis. Apatinib combined with the mTOR inhibitor CCI-779 can sensitize the NCI-H446 cells to Apatinib.
