-
Orostachys japonicus (O. japonicus) is utilized as a traditional medicine for patients with various diseases. This study investigated the effect of the ethyl acetate fraction from O. japonicus extract (OJE) on the growth inhibition of OVCAR‐3 human ovarian cancer cells demonstrated to inhibit cell growth and arrest the cell cycle in OVCAR‐3 cells by blocking the sub‐G1 phase and decreasing cyclin E1/CDK2 expression. Cell cycle arrest was connected to the increased expression of the cell cycle regulating factors p53 and p21. Apoptosis was initiated through the intrinsic pathway by up‐regulating the expression of the Bcl‐2/Bax ratio and down‐regulating the expression of pro‐caspase‐3. Furthermore, OJE treatment elicited p‐p38 activation and p‐ERK1/2 inhibition. In conclusion, our results demonstrated that OJE reduced the growth of OVCAR‐3 human ovarian cancer cells mediated by arrest of the cell cycle and regulation of MAPK signaling pathways.
