H2O2-induced phosphorylation of ERK1/2 and PKB requires tyrosine kinase activity of insulin receptor and c-Src.


Hydrogen peroxide (H2O2) mimics many physiological responses of insulin, and increased H2O2 generation via the Nox-4 subunit of NAD(P)H oxidase was recently demonstrated to serve as a critical early step in the insulin signaling pathway. Exogenously added H2O2 has also been shown to activate several key components of the insulin signaling cascade. H2O2… (More)
