SH2B1β reduces H 2 O 2 -induced expression of FasL through PI3K-AKT and MEK-ERK1/2. PC12-GFP and PC12-SH2B1β cells were incubated in serum-free medium overnight, before H2O2 (0, 100, or 200 μM) treatment for 4 h without (A) or with 20 μM LY294002 (+LY) (B, C) or 20 μM U0126 (+U) (D, E) pre-treatment for 30 min. The expression of FasL was determined by Q-PCR. The relative levels of FasL were normalized to the expression of GAPDH. The relative expression levels of H2O2-treated samples were normalized to untreated samples in each cell line for each experiment. Values are expressed as mean ± S.E. from three independent experiments and statistically compared using student's t-test (*, P < 0.05). For inhibitor assays, results from PC12-GFP cells are shown on the left panels and those from PC12-SH2B1β cells are shown on the right.
