1 Although elevation of the blood glucose level is a causal adverse effect of treatment with interferon (IFN), the precise underlying molecular mechanism is largely unknown. Glucose interferon gamma Homo sapiens
2 We examined the effects of type I and type II IFN (IFN-beta and IFN-gamma) on insulin-induced metabolic signaling leading to glucose uptake in 3T3-L1 adipocytes. Glucose interferon gamma Homo sapiens
3 In contrast, adenovirus-mediated expression of a dominant-negative STAT3 (F-STAT3) attenuated IFN-gamma-induced SOCS3 expression, reduction of IRS-1 protein, and suppression of insulin-induced glucose uptake but did not have any effect on the IFN-beta-mediated SOCS1 expression and inhibition of insulin-induced glucose uptake. Glucose interferon gamma Homo sapiens
