Endocrine, metabolic and cardioprotective effects of hexarelin in obese Zucker rats.
Genetically obese male Zucker rats have an impaired secretion of GH, coupled to hyperinsulinemia, hyperlipidemia and glucose intolerance. The aim of this study was to evaluate whether a chronic treatment with hexarelin, a synthetic enkephalin-derived hexapeptide with a potent GH-releasing activity, might be able to ameliorate the somatotropic function and reverse some metabolic alterations asso...
متن کاملGrowth hormone-independent cardioprotective effects of hexarelin in the rat.
We previously reported that induction of selective GH deficiency in the rat exacerbates cardiac dysfunction induced by experimental ischemia and reperfusion performed on the explanted heart. In the same model, short-term treatment with hexarelin, a GH-releasing peptide, reverted this effect, as did GH. To ascertain whether hexarelin had non-GH-mediated protective effects on the heart, we compar...
متن کاملEffects of Endogenous PPAR Agonist Nitro-Oleic Acid on Metabolic Syndrome in Obese Zucker Rats
Nitroalkene derivatives of nitro-oleic acid (OA-NO(2)) are endogenous lipid products with novel signaling properties, particularly the activation of PPARs. The goal of this proposal was to examine the therapeutic potential of this OA-NO(2) in treatment of obesity and obesity-related conditions in obese Zucker rats. The animals were randomly divided to receive OA-NO(2), oleic acid (OA), both at ...
متن کاملAttenuated PGI2 synthesis in obese Zucker rats.
In obesity, skeletal muscle blood flow during exercise (functional hyperemia) is impaired. We have indirectly demonstrated that an altered arachidonic acid metabolism is responsible for the impaired functional vasodilation in the obese Zucker rat (OZR), a model of obesity. In this study, we tested the hypothesis that there is an impaired release of PGI(2) due to a nitration of PGI(2) synthase (...
