Figure 10. Effect of 4-HNE on the expression of various proteins in hGSTA4 overexpressing HepG2 cells and Gsta4 null mice.
(A) Effect of 4-HNE (20 µM, 2 h) on the expression of Daxx, p53, ASK1, Fas, JNK and Bax in empty vector- and hGSTA4-transfected HepG2 cells (B) Expression analysis of apoptotic proteins in liver samples of normal and mGSTA4 (−/−) mice. Mice liver samples were homogenized in ice-cold RIPA buffer and centrifuged at 12,000 g and the supernatants were subjected to western blot analysis for the expression of Daxx, Fas, p-SEK1 (Thr261), JNK, HSF1, p53, and ASK1. β-actin was used as the loading control.
