Erianin inhibits human cervical cancer cell through regulation of tumor protein p53 via the extracellular signal-regulated kinase signaling pathway.

Erianin inhibits human cervical cancer cell through regulation of tumor protein p53 via the extracellular signal-regulated kinase signaling pathway. Oncol Lett. 2018 Oct;16(4):5006-5012 Authors: Li M, He Y, Peng C, Xie X, Hu G Abstract Erianin, a natural bibenzyl compound, is present in Dendrobium chrysotoxum Lindl. (commonly known as Shihu in China), which is used as an antipyretic and analgesic in traditional Chinese medicine, and has been reported to exert inhibitory effects on cancer cells in vitro. Cervical cancer is the third-most common cancer in women worldwide, and has the highest morbidity rate of gynecological malignancies. Thus, the identification of effective chemotherapeutical agents to treat this disease is urgent. The aim of the present study was to elucidate the biological functions and molecular mechanism of erianin on HeLa cells. Cellular proliferation was assessed using an MTT assay and flow cytometry assay with propidium iodide (PI) staining. Apoptosis rates were observed using a high content screening system via annexin V-fluorescein isothiocyanate/PI double staining, and measured by flow cytometry. The protein levels of tumor protein p53, extracellular signal-regulated kinase 1/2 (ERK1/2), caspase-3, B-cell lymphoma-2 (Bcl-2) and Bcl-2-associated X (Bax) were assessed by western blot analysis. Erianin inhibited the growth of HeLa cells and induced apoptosis in a dose- and time-dependent manner, inducing cell cy...
