Insulin receptor substrate-1 (Irs1) is one of the major substrates for insulin and insulin-like growth factor-1 (IGF-1) tyrosine kinases. Systemic Irs1-deficient mice show retardation, with resistance to IGF-1, although underlying mechanisms remain poorly understood. For this study, we generated brain-specific deletion Irs1 (NIrs1KO mice). The NIrs1KO exhibited lower body weights, shorter bodie...
objective: micro-rnas (mirnas) are a class of posttranscriptional regulators that play crucial roles in various biological processes. emerging evidence suggests a direct link between mirnas and development of several diseases including type 2 diabetes (t2d). in this study, we aimed to investigate the effect of predicted mirna and target genes on insulin resistance. materials and methods: this e...
Diabetes reduces basal retinal insulin receptor signaling: reversal with systemic and local insulin.
Diabetic retinopathy is characterized by early onset of neuronal cell death. We previously showed that insulin mediates a prosurvival pathway in retinal neurons and that normal retina expresses a highly active basal insulin receptor/Akt signaling pathway that is stable throughout feeding and fasting. Using the streptozotocin-induced diabetic rat model, we tested the hypothesis that diabetes dim...
To examine the role of clathrin-dependent insulin receptor internalization in insulin-stimulated signal transduction events, we expressed a dominant-interfering mutant of dynamin (K44A/dynamin) by using a recombinant adenovirus in the H4IIE hepatoma and 3T3L1 adipocyte cell lines. Expression of K44A/dynamin inhibited endocytosis of the insulin receptor as determined by both cell surface radioli...
