摘要
Abstract
Objective To investigate the effect of rhein lysinate (RHL) on inducing human cervical cancer cell line HeLa apoptosis and the role of activation of c-Jun N-terminal kinase (JNK) in cell apoptosis.Methods MTT assay was used to detect HeLa cell proliferation.Cell apoptosis was analyzed by flow cytometry.The protein associated with apoptosis and the protein phosphorylation of JNK was detected by Western blot.Results RHL remarkably inhibited cervical cancer HeLa cells proliferation.The IC50 value for 48 and 72 h treatment was 81.18 μmol/L and 72.38 μmol/L respectively.Apoptosis of HeLa cells was induced by RHL in a dose dependent manner.RHL triggered HeLa cells apoptosis by increasing the level of cleaved poly ADP-ribose polymerase (PARP)and caspase-3/7.In addition, activation JNK was a critical mediator in RHL-induced growth inhibition.Inhibition of the phosphorylation of JNK by pharmacological inhibitors reversed the RHL-induced growth inhibition through decreasing the level of cleaved PARP and caspase-3/7.Conclusion RHL suppresses HeLa cells growth and induces apoptosis through activation of JNK-caspase-PARP signal pathway, with the potential to be developed as a chemotherapeutic agent for cervical cancer.关键词
