In vitro studies of H520 cell cycle and apoptosis by anlotinib combined with radiotherapy

Background To study in vitro the effects of anlotinib combined with radiotherapy on the lung cancer H520 cell cycle and apoptosis. Methods The log growth period H520 cells were divided into the control group, anlotinib group (A group), radiotherapy group (RT group) and combined group (A + RT group). Cell cycle and apoptosis were detected by flow cytometry and changes in H520 cell cycle and apoptosis were analyzed in each group. Results Anlotinib was determined to significantly inhibit cell growth in all groups, both alone, or in combination with radiotherapy. After receiving corresponding treatments, the proportions of G2/M‐phase cells in the control group, A group, RT group and A + RT group were different, and statistically significant (F = 32.086, P
