     U0126 protects PC12 cells against H2O2-induced cell death. Western blot of ERK phosphorylation demonstrates that the MEK inhibitors U0126, GSK1120212 and Pimasertib are effective in blocking ERK phosphorylation under complete media, while U0124 results in slight ERK inhibition compared to DMSO control. Serum starvation results in lack of ERK phosphorylation in all conditions.
