Fig. 6. TNFα and CHX trigger an apoptotic response in cFLIP knockdown FHL124 cells by activating caspase-8, caspase-9, and caspase-3.
A Activated caspase-8 was detected in cFLIP KD3 cFLIP knockdown FHL124 cells from 5 h to 24 h TNFα and CHX treatment. Similar results were seen in activated caspase-9 and caspase-3. PARP-1 cleavage was detected at 7 h and 24 h time point after the stimulation. B–E The semi-quantitative densitometric measurement. One-way ANOVA was used to compare between groups, and only p < 0.05 is considered significant. *<0.05, **<0.01, ***<0.001, ****<0.0001.
