Amylin (8-37), rat (Synonyms: Amylin (8-37) (mouse, rat))

Amylin (8-37), rat is a truncated analog of native Amylin that selectively inhibits insulin-related glucose uptake and glycogen deposition in muscle tissue. Amylin (8-37), rat is a weak amylin receptor (AMY) antagonist. Amylin receptor (AMY)[1]

Amylin (8-37), rat (Rat amylin-(8-37)) enhances insulin action and alters lipid metabolism in normal and insulin-resistant rats. Amylin (8-37) reduces plasma insulin (P<0.001) and enhances several measures of whole body and muscle insulin sensitivity (P<0.05) in both saline- and hGH-infused rats. Amylin-(8-37) corrects hGH-induced liver insulin resistance, increases basal plasma triglycerides and lowers plasma nonesterified fatty acids in both groups, and reduces muscle triglyceride and total long-chain acyl-CoA content in saline-treated rats (P<0.05). In isolated soleus muscle, Amylin (8-37) blocks amylin-induced inhibition of glycogen synthesis but has no effect in the absence of amylin. Thus 1) hyperamylinemia accompanies insulin resistance induced by hGH infusion; 2) Amylin (8-37) increases whole body and muscle insulin sensitivity and consistently reduces basal insulin levels in normal and hGH-induced insulin resistant rats; and 3) Amylin (8-37) elicits a significant alteration of in vivo lipid metabolism[2].
