Fig. 5. Levels of apoptosis-associated proteins following treatment with parthenolide (PT) and balsalazide. HCT116 cell lysates were prepared after treatment with PT, balsalazide, or PT and balsalazide for 24 h and analyzed by western blotting using B-cell lymphoma 2 (Bcl-2), B-cell lymphoma-extra large (Bcl-xL), Bid, Bcl-2-associated X protein (Bax), and cytochrome c antibodies. Actin was used as the loading control.
