Abstract

Oridonin is an active component of the traditional Chinese herb Rabdosia rubescens. The present study aimed to evaluate the antitumor effects of oridonin on human non‑small cell lung cancer (NSCLC) cells and explore whether oridonin could enhance their radiosensitivity. Oridonin was demonstrated to inhibit the proliferation of SPC‑A‑1 and HCC827 lung cancer cells in a time‑ and dose‑dependent manner, which was detected using the MTT assay. In addition, pretreatment with oridonin for 24 h prior to irradiation was identified to enhance the radiosensitivity of SPC‑A‑1 cells. Furthermore, the levels of apoptosis regulator BAX (Bax) and apoptosis regulator Bcl‑2 (Bcl‑2) were detected by western blotting analysis. The results demonstrated that the level of Bax was increased and the level of Bcl‑2 was decreased in SPC‑A‑1 cells treated with oridonin and irradiation compared with the group that received irradiation alone. These results indicate that oridonin may have a novel application as a radiosensitizing agent for the treatment of human NSCLC.
