Effects of CTS on extrinsic pathway-related factors in SiHa cervical cancer cells.

(A) mRNA levels of TRAIL, DR5 and Fas as detected by qRT-PCR. (B) Western blot analysis of extrinsic pathway-related factors. SiHa cells were treated with the indicated concentration of CTS for 24 h. (C) Western blot analysis of the effects of CTS following pretreatment with general caspase inhibitor Z-VAD-FMK or caspase-8 inhibitor Z-IETD-FMK in SiHa cells.
