, genetically fat or lean chickens, or exogenous insulin challenge ( Dupont et al . 1998 a , b , c , 1999 , 2004 )). In contrast, these signaling steps (with the exception of Shc) were not altered in leg muscles by the various experimental conditions. This

metabolic action ( Rincon et al. 1996 , Diamanti-Kandarakis & Dunaif 2012 ). It has been proposed that insulin resistance is caused by a post-binding defect in the insulin signaling pathway and/or related to mutations in the insulin receptor ( IR ) gene

Introduction Insulin-like growth factor-I (IGF-I) and insulin are part of the complex regulatory mechanisms that help to maintain normal myocardial function ( Abel 2004 , Saetrum & Wang 2005 ). Signaling pathways of IGF-I receptor

insulin signaling at the level of insulin-receptor substrate (IRS)-1 phosphorylation ( Schütt et al. 2000 , Cammalleri & Germinario 2003 ), association of the p85 subunit of phosphatidylinositol 3-kinase (PI3-kinase; Schütt et al. 2000 ) and/or Thr

(IR) ( Dulloo & Montani 2012 ). IR is a hallmark of T2D, in which insulin at normal physiological concentrations fails to effectively activate its downstream signal transduction in the skeletal muscle, liver and adipose tissue ( Hartstra et al. 2015

cardiomyopathy. In this review, we discuss the mechanisms of insulin in governing cardiac energetics, and update on how insulin resistance promotes cellular dysfunction at the molecular level with interacting signaling cascade involving in IRS-1, -2 and Foxo1

attenuated insulin-like signaling or increased oxidative stress, promotes anti-oxidative function, contributing to the lifespan extension in Caenorhabditis elegans ( Lee et al. 2003 ). Likewise, the FoxO1 ortholog dFoxO signaling through insulin

investigated the effects of prolonged insulin on GH signaling via the other two STATs (STAT3 and STAT1) in rat H4IIE hepatoma cells. We found that prolonged insulin pretreatment inhibited not only GH-induced tyrosine phosphorylation (PY) of STAT3 and STAT1 but
