In the present study, we investigated whether cholecystokinin (CCK) or its structurally related peptide gastrin participates in long term regulation of adipocyte leptin secretion. The levels of circulating leptin observed after 2 and 6 h of refeeding in 18-h fast rats were significantly lowered by injection of the specific gastrin/CCK-B receptor antagonist YM022 at doses that did not affect fee...

BACKGROUND Leptin has been identified as an important protein involved in obesity. As a chronic metabolic disorder, obesity is associated with a high risk of developing cardiovascular and metabolic diseases, including heart failure. The aim of this paper was to investigate the effects and the mechanism of leptin on the contractile function of cardiomyocytes in the adult rat. METHODS Isolated ...

This study was conducted to enhance broccoli secondary metabolites; using plant biotechnology techniques and tissue culture as well evaluate the therapeutic effect of extract against osteoporosis in ovariectomized (OVX) rats. Cell technique implemented order achieve produce polyphenols from leaf explants broccoli. The high-performance liquid chromatography (HPLC) used polyphenolic profiles etha...

Our previous studies demonstrate that 17beta-estradiol limits chronic volume overload-induced hypertrophy and improves heart function in ovariectomized rats. One possible cardioprotective mechanism involves the interaction between estrogen, estrogen receptors, and proteins of the extracellular matrix (ECM). The impact of estrogen deficiency and replacement on left ventricular (LV) hypertrophy a...

BACKGROUND Leptin regulates appetite through the long isoform of its receptor in the hypothalamus. Although leptin regulates immune responses, it is still unknown whether a direct effect of leptin on lymphocytes is required. AIMS To clarify whether expression of leptin receptors on T lymphocytes modulates intestinal inflammation in mice. METHODS The model of colitis induced by transfer of C...

conclusions it appears that fenugreek seed might be effective against hyperglycemia, hyperlipidemia and insulin resistance in ovariectomized rats without impact on serum apelin. furthermore, 17-β estradiol could have similar effects along with possible inhibitory effects on serum apelin. the complicated role of apelin in menopause needs to be further explored. results serum apelin, glucose, lip...

Hypothalamic leptin signalling has a key role in food intake and energy-balance control and is often impaired in obese individuals. Here we identify histone deacetylase 5 (HDAC5) as a regulator of leptin signalling and organismal energy balance. Global HDAC5 KO mice have increased food intake and greater diet-induced obesity when fed high-fat diet. Pharmacological and genetic inhibition of HDAC...

Growth hormone (GH) is known to interact with adipose tissue and to induce lipolysis. Adipocytes produce leptin which regulates appetite and energy expenditure. In order to elucidate the role of GH in leptin production, we studied the effect of GH on leptin gene expression and body fat in fatty Zucker rats, a model of obesity with resistance to both leptin and insulin. Recombinant human GH admi...

Most small homotherms display low leptin level in response to chronic cold exposure. Cold-induced hypoleptinemia was proved to induce hyperphagia. However, it is still not clear whether hypoleptinemia regulates energy expenditure in cold condition. We try to answer this question in chronic cold-acclimated rats. Results showed that 5-day intracerebroventricular(ICV) infusion of leptin (5 μg/day)...
