However, non-small lung cancer cells are insensitive to radiation, diminishing their radiotherapy effects. Although the radiosensitivity of the non-small lung cancer cells was reported to be enhanced through regulating miR-34a, the regulation effects of miR-34a expression on radiosensitivity of lung adenocarcinoma cells through target genes CDK4, CDK6, CyclinD1, and Bcl-2/Bax have not been systematically investigated. Methods: In this study, we investigated the effect of miR-34a expression on the Bcl-2, CDK4, and CDK6 pathways in lung adenocarcinoma cells, to provide new insights into the sensitization treatment of lung cancer. We first studied the effect of miR-34a expression on H1299 and A549 cell activity. Then to investigate the mechanisms of radiosensitivity, we focused on apoptosis, cell cycle, and target genes. Results: We find that overexpression of miR-34a in lung adenocarcinoma cells inhibits cell activity, and improves radiosensitivity. Specifically, overexpression of miR-34a suppresses the expression of target genes CDK4, CDK6, CyclinD1, and Bcl-2/Bax, which leads to cell cycle arrest and promotes apoptosis of lung adenocarcinoma cells. Conclusions: Overall, our results demonstrate that the overexpression of miR-34a enhances the radiosensitivity of lung adenocarcinoma cells, indicating that miR-34a is a sensitizer for lung adenocarcinoma radiotherapy.展开更多
