Ghrelin, a novel 28 amino acid peptide found in hypothalamus and stomach, was recently identified as the endogenous ligand for the growth hormone secretagogue receptor (GHS-R). We have now found that… (More)

Ketogenic diets have been used as an approach to weight loss on the basis of the theoretical advantage of a low-carbohydrate, high-fat diet. To evaluate the physiological and metabolic effects of… (More)
The gastrointestinal-derived hormone peptide YY (PYY) is released from intestinal L-cells post-prandially in proportion to calorie intake, and modulates food intake. Peripheral administration of… (More)
Cocaine- and amphetamine-regulated transcript is expressed in hypothalamic regions involved in the central control of food intake. Previous data have implicated cocaine- and amphetamine-regulated… (More)
The central nervous system and gut peptide neuromedin U (NMU) inhibits feeding after intracerebroventricular injection. This study explored the hypothalamic actions of NMU on feeding and the… (More)
The hypothalamic neuropeptide melanin-concentrating hormone (MCH) increases feeding when injected intracerebroventricularly in rats. To identify the hypothalamic nuclei responsible for the orexigenic… (More)

In mice of normal weight and with diet-induced obesity, a high-fat, low-carbohydrate ketogenic diet (KD) causes weight loss, reduced circulating glucose and lipids, and dramatic changes in hepatic… (More)
The distribution of orexin A-immunoreactive neurons and orexin type I receptors in the CNS suggests important roles in regulating the hypothalamo-pituitary gonadal (HPG) axis and sexual behaviors. We… (More)
Orexin A stimulates GnRH release from hypothalamic explants in vitro. The sites of action of orexin A in the regulation of LH release have been investigated in vivo in ovariectomized rats that were… (More)
