Figure 5From: Parthenolide induces proliferation inhibition and apoptosis of pancreatic cancer cells in vitroApoptosis-related protein expression after PTL treatment for 48 hours. (A) PTL decreased Bcl-2 expression and induced Bax expression. No obvious change was observed on Bad; (B) Bcl-2/Bax ratio was decreased significantly with the increasing concentration of PTL; (C) Activation of caspase-9 and caspase-3 after PTL treatment.Back to article page
