SPL-A sensitizes human endometrial carcinoma cells to TRAIL-mediated apoptosis.
Notes: Human endometrial carcinoma cell lines HEC-1A and RL-952 were treated with SPL-A alone, TRAIL alone, or SPL-A plus TRAIL for 24 h. (A) The sub-G1 fraction was analyzed by FCM analysis. (B) Western blot analysis of cleaved PARP. β-actin was loading control. (C) Ishikawa cells were treated with different concentrations of SPL-A. Western blot analysis of c-FLIP, Bcl-2, Bcl-xL, Mcl-1, cIAP1, and XIAP. β-actin was loading control. The results are shown as mean ± SD (n=5). *p<0.05 compared to SPL-A alone or TRAIL alone.
Abbreviations: FCM, flow cytometry; SPL-A, spindlactone A.
