The derangement of endoplasmic reticulum (ER) homeostasis triggers β-cell apoptosis, leading to diabetes. Glucokinase upregulates insulin receptor substrate 2 (IRS-2) expression in β-cells, but the role of glucokinase and IRS-2 in ER stress has been unclear. In this study, we investigated the impact of glucokinase activation by glucokinase activator (GKA) on ER stress in β-cells. GKA administra...
The signaling pathways used by insulin have been identified [M. White, Insulin Signaling Pathway, Sci. STKE (Connections Map, as seen November 2003), http://stke.sciencemag.org/cgi/cm/cmp_12069]. Now our challenge is to understand how the failure of these signals is associated with obesity and the progressive failure of pancreatic beta cells that leads to diabetes. Whether better management of ...
BACKGROUND Long-term exposure to high levels of fatty acids impairs insulin secretion and exaggerates glucagon secretion. The aim of this study was to explore if the antihyperglycemic agent, Isosteviol (ISV), is able to counteract palmitate-induced α-cell dysfunction and to influence α-cell gene expression. METHODOLOGY/PRINCIPAL FINDINGS Long-term incubation studies with clonal α-TC1-6 cells ...
UNLABELLED The insulin signaling pathway is critical for the control of blood glucose levels. Brown adipose tissue (BAT) has also been implicated as important in glucose homeostasis. The effect of short-term cold exposure on this pathway in BAT has not been explored. We evaluated the effect of 4 hours of cold exposure on the insulin pathway in the BAT of rats. Whole genomic microarray chips wer...
