The mechanisms underlying this association are partly understood. Increased levels of tumor necrosis factor (TNF)-α occurring in HCV infection have an important role in HCV-mediated insulin resistance; however,(More)
OBJECTIVE Cellular stress and proinflammatory cytokines induce phosphorylation of insulin receptor substrate (IRS) proteins at Ser sites that inhibit insulin and IGF-1 signaling. Here, we examined the role of Ser phosphorylation of IRS-2 in mediating the inhibitory effects of proinflammatory cytokines and cellular stress on beta-cell function. RESEARCH(More)
