Energetic demands of lactation produce an increase in the expression of growth hormone secretagogue receptor in the hypothalamus and ventral tegmental area of the rat despite a reduction in circulating ghrelin

Author(s): Wellman M; Budin R; Woodside B; Abizaid A;

Lactating rats show changes in the secretion of hormones and brain signals that promote hyperphagia and facilitate the production of milk. Little is known, however, about the role of ghrelin in the mechanisms sustaining lactational hyperphagia. Here, we use ...

Ghrelin receptor signalling is not required for glucocorticoid-induced obesity in female mice

Author(s): Silver Z; Abbott-Tate S; Hyland L; Sherratt F; Woodside B; Abizaid A;

Chronic exposure to high circulating glucocorticoid or ghrelin concentrations increases food intake, weight gain and adiposity, suggesting that ghrelin could contribute to the metabolic effects of chronic glucocorticoids. In male mice, however, blocking ghr ...

A role for leptin and ghrelin in the augmentation of heroin seeking induced by chronic food restriction.

Author(s): D'Cunha TM, Chisholm A, Hryhorczuk C, Fulton S, Shalev U

RATIONAL: Caloric restriction increases the risk of relapse in abstinent drug users. Hormones involved in the regulation of energy balance and food intake, such as leptin and ghrelin, are implicated in drug-related behaviors. OBJECTIVES: We investigated the ...
