WebWestern-Blot was to determine the levels of the proteins involved in the mitochondrial cell apoptosis pathway (including cytosolic CytC, cytosolic AIF, mitochondrial CytC, mitochondrial AIF, Mfn2 and FIS1), signaling pathways mediated by the intraplasmic reticulum stress (including GRP78, XBP-1, eIF2α, CHOP, ASK), the death receptor … WebTo confirm that CHOP mediates cell apoptosis in H1975, we silenced CHOP through siRNA and then exposed the cells to WZ35. Our results clearly show that WZ35-induced cell death in H1975 is significantly dampened upon producing CHOP deficit. We further showed that WZ35-induced ER stress is abolished when ROS is neutralized by NAC.
