ABSTRACT
Objective To investigate the effects of cyclopamine (CYP) on endometrial carcinoma (HEC-1A) cell survival and on induction of cell apoptosis .Methods HEC-1A cells were treated with various doses of CYP (0, 5,10, 20 and 40 μmol/L) for 24 h respectively .Then,the inverted microscope was used to observe cell morphology .Cell proliferation and apoptosis were tested by CCK-8 assay and AO/EB bi-labelling assay.The apoptosis rate of HEC-1A was analyzed using flow cytometric analysis , and the key gene expression of Bax and Bcl-2 was detected by quantitative PCR .Results The HEC-1A cells exhibited dramatic morphological changes after treatment with CYP and in a dose-dependent manner .CYP significantly inhibited HEC-1A cell proliferation using CCK8 assays(P<0.05), and induced cell death by AO/EB bi-labelling assay.Moreover,flow cytometry analysis showed that CYP treatment resulted in HEC-1A cell apoptosis, and that a higher concentration of CYP induced severer cell apoptosis (P<0.05).Meanwhile, CYP treated HEC-1A cells exhibited up-regulated expression of Bax and down-regulated expression of Bcl-2 according to Q-PCR.Conclusion Our findings indicatee that CYP can inhibit HEC-1A cell proliferation and induce cell apoptosis .
