Effect of mimitin gene silencing on caspase 3/7 activities. HepG2 cells were transfected with mimitin-siRNA, GAPDH-siRNA, negative control siRNA, or transfection reagent (siPORT NeoFX) (blank). Apoptosis was induced 72 h post transfection by treatment of cells with TNF/CHX for 5 h. Caspase 3/7 activity was measured using Caspase-GloTM3/7 assay kit. A. Changes in caspase activity in cells with TNF/CHX-induced apoptosis were compared to cells treated with TNF/CHX and transfected with a negative control siRNA (assumed as equal 1). In each case the value of caspase 3/7 activity after TNF/CHX treatment was divided by the value of basal activity of non-stimulated cells. Values represent the mean of three independent experiments with error bars showing standard error (*p < 0.05). B. Representative Western blot analysis with 20 μg protein from caspase activity assay using anti-GAPDH and anti-Mimitin antibodies. Samples marked (+) were stimulated with TNF/CHX while samples marked (-) were not stimulated.
