A. The viability of gastric cancer cells in response to Apatinib in SGC-7901 (left panel), BGC-823 (middle panel), and MGC-803 cells (right panel). B. Treating with Apatinib, proliferation of gastric cancer cell lines in response to rhVEGF in SGC-7901 (left panel), BGC-823 (middle panel), and MGC-803 cells (right panel). C. Treating cells with Apatinib at different concentration affected secretion of VEGF in SGC-7901 (left panel), BGC-823 (middle panel), and MGC-803 cells (right panel). D. The protein levels were measured by Western blot after treating cells with Apatinib. GAPDH was included as a loading control. Mean±SEM, t-test, *P<0.05, **P<0.01, ***P<0.001.
