Chronic PYY3-36 treatment promotes fat oxidation and ameliorates insulin resistance in C57BL6 mice.
PYY(3-36) is a gut-derived hormone acting on hypothalamic nuclei to inhibit food intake. We recently showed that PYY(3-36) acutely reinforces insulin action on glucose disposal in mice. We aimed to evaluate effects of PYY(3-36) on energy metabolism and the impact of chronic PYY(3-36) treatment on insulin sensitivity. Mice received a single injection of PYY(3-36) or were injected once daily for ...
متن کاملEvaluation of Diabetogenic Mechanism of High Fat Diet in Combination with Arsenic Exposure in Male Mice
Obesity is a main reason of type 2 diabetes and also chronic exposure to arsenic (As)can produce diabetic symptoms. In previous studies, the association between high-fat dietand arsenic in the incidence of diabetes was found, but the role of beta cells activity, livermitochondrial oxidative stress, and hepatic enzymes (leptin, adiponectin and beta amylase)was unclear. Thus, present study was co...

متن کاملPYY(3-36) reduces food intake and body weight and improves insulin sensitivity in rodent models of diet-induced obesity.
The gut hormone peptide YY (PYY) was recently proposed to comprise an endogenous satiety factor. We have studied acute anorectic functions of PYY(3-36) in mice and rats, as well as metabolic effects of chronic PYY(3-36) administration to diet-induced obese (DIO) mice and rats. A single intraperitoneal injection of PYY(3-36) inhibited food intake in mice, but not in rats. We next investigated th...

Objective(s): The present study was aimed to evaluate the effect of methanolic fruit extract of Momordica cymbalaria (MeMC) against high-fat diet-induced obesity and diabetes in C57BL/7 mice.Materials and Methods: In the present study, six weeks old male C57BL/6 mice were divided into four groups. G-1 and G-2 served as lean control and HFD control, G-3 and G-4 received MeMC 25 and 50 mg/kg, BW ...
