Insulin receptor substrate-2 (Irs2) in endothelial cells plays a crucial role in insulin secretion.
Endothelial cells are considered to be essential for normal pancreatic β-cell function. The current study attempted to demonstrate the role of insulin receptor substrate-2 (Irs2) in endothelial cells with regard to insulin secretion. Endothelial cell-specific Irs2 knockout (ETIrs2KO) mice exhibited impaired glucose-induced, arginine-induced, and glucagon-induced insulin secretion and showed glu...
متن کاملJNK3 Maintains Expression of the Insulin Receptor Substrate 2 (IRS2) in Insulin-Secreting Cells: Functional Consequences for Insulin Signaling
We have recently shown that silencing of the brain/islet specific c-Jun N-terminal Kinase3 (JNK3) isoform enhances both basal and cytokine-induced beta-cell apoptosis, whereas silencing of JNK1 or JNK2 has opposite effects. While it is known that JNK1 or JNK2 may promote apoptosis by inhibiting the activity of the pro-survival Akt pathway, the effect of JNK3 on Akt has not been documented. This...
متن کاملDifferential insulin receptor substrate-1 (IRS1)-related modulation of neuropeptide Y and proopiomelanocortin expression in nondiabetic and diabetic IRS2-/- mice.
Insulin resistance and type 2 diabetes correlate with impaired leptin and insulin signaling. Insulin receptor substrate-2 deficient (IRS2(-/-)) mice are an accepted model for the exploration of alterations in these signaling pathways and their relationship with diabetes; however, disturbances in hypothalamic signaling and the effect on neuropeptides controlling food intake remain unclear. Our a...
متن کاملInvolvement of insulin receptor substrate 2 in mammary tumor metastasis.
The insulin receptor substrate (IRS) proteins are adaptor molecules that integrate signals generated by receptors that are implicated in human breast cancer. We investigated the specific contribution of IRS-2 to mammary tumor progression using transgenic mice that express the polyoma virus middle T antigen (PyV-MT) in the mammary gland and IRS-2-null (IRS-2(-/-)) mice. PyV-MT-induced tumor init...
متن کاملInsulin receptor substrate-2--a new candidate gene for NIDDM?
The pathogenesis of non-insulin-dependent diabetes mellitus (NIDDM) includes the development of insulin resistance and, at a later stage, impairment of b-cell response. In the past few years, different elements, including the proto-oncogene, Shc, and the insulin receptor substrate (IRS) proteins, have been found to have important roles in the insulin signaling network. Whithers et al. (1) have ...
