Effects of PEP-1-GLRX1 on MPP+-induced apoptotic protein expression in SH-SY5Y cells. GLRX1 or GLRX1 (3 μM) for 1 h before being treated with MPP+ (5 mM). Bcl-2 and Bax (A), Caspase-3 (B), and Caspase-9 (C) expression levels were analyzed by Western blotting. Band intensity was measured by densitometer. **p < 0.01, compared with MPP+ treated cells. The bars in the figure represent the mean ± SEM obtained from three independent experiments.
