Succinyl rotundic acid inhibits growth and promotes apoptosis in the HeLa cervical cancer cell line

Rotundic acid (RA) is a kind of pentacyclic triterpene saponins, which widely exists in holly and other plants. It has anti-tumor and lipid-lowering effects, and has been widely used in the prevention and treatment of vascular diseases. Succinyl RA (SRA) is a kind of circular acid derivative
 with strong water solubility. However, SRA’s effect and mechanism about the therapy of cervical cancer is still not clarified. The inhibitory effect of SRA on Hela cells and its molecular mechanism were investigated in this study. Hela cell line was used to establish an in vitro
 model to study the effect of SRA. The effects of SRA on cell proliferation, cell cycle and apoptosis were analyzed by flow cytometry and detected by 3-(4,5-dimethyl thiazole-2-yl)-2, 5-diphenyltetrazole bromide. The experimental results show that SRA can inhibit the growth of Hela and diffusion,
 inducing cell apoptosis. SRA can also reduce the expression of CyclinD 1 and p21. It was also decreased the expression of apoptosis inhibitor B cell lymphoma (Bcl-2), and increased the expression of Bcl-2-related X-protein and Caspase-3. This study provides evidence for
 the progress of SRA in inhibiting Hela cells and presents potential applications of SRA as an alternative therapy for cervical cancer.
