Octreotide (SMS 201-995) is a somatostatin receptor agonist and synthetic octapeptide endogenous somatostatin analogue. Octreotide (SMS 201-995) can bind to the somatostatin receptor and mainly subtypes 2, 3, and 5, increases Gi activity, and reduces intracellular cAMP production. Octreotide (SMS 201-995) has antitumor activity, mediates apoptosis and may also be used in disease studies in acromegaly[1][2].
Octreotide reverses the PA-induced alterations in Akt and GSK3β phosphorylation and expression of GS mRNA in HepG2 cells[1].
Octreotide (10 8mM, 6 hours) induces phosphorylated glycogen synthase kinase 3β (GSK3β) phosphorylation and increases glycogen synthase (GS) activity[3].
Octreotide significantly lowers the plasma glucose levels in the obese rats of the HFD group. Octreotide intervention significantly decreases the serum insulin concentration; however, there is no marked reduction in serum TG, TC, FFA, ALT and AST levels. Octreotide significantly inhibits the HOMA index. Octreotide decreases ipGTT and ipITT AUCs, but not significantly. Octreotide improves fat degeneration in rats with HFD-induced obesity and lipid droplet accumulation in PA-treated HepG2 cells. Octreotide promotes the phosphorylation of Akt and GSK3β and the expression of GS mRNA in rats with HFD-induced obesity[1]. Octreotide reduces body weight and wet kidney weight compared with the vehicle-treated (CONT) group. PAS and Octreotide/PAS treatment decrease cAMP levels, but Octreotide alone does not in PCK rats. In the Octreotide/PAS group, there are a significantly fewer pS6-positive cells than in the PAS alone group[2].
