Figure 6From: Parthenolide induces apoptosis via TNFRSF10B and PMAIP1 pathways in human lung cancer cellsParthenolide up-regulates endoplasmic reticulum hallmarks ERN1, HSPA5 and p-EIF2A in a dose-dependent (A) and a time-dependent (B) manner. The indicated cells were treated with indicated concentrations of PTL for 24 hrs (A) or treated with 20 μmol/L PTL for various lengths of time and harvested for Western blot analysis (B).Back to article page
