Prokineticin 2 is a hypothalamic neuropeptide that potently inhibits food intake (2009)
Journal Article

OBJECTIVE-Prokineticin 2 (PK2) is a hypothalamic neuropeptide expressed in central nervous system areas known to be involved in food intake. We therefore hypothesized that PK2 plays a role in energy homeostasis. RESEARCH DESIGN AND METHODS - We inves...

The role of histamine 3 receptors in the control of food intake in a seasonal model of obesity: The Siberian hamster (2009)
Journal Article

Siberian hamsters develop hypophagia and increase catabolism of fat reserves in response to short photoperiods resulting in a natural loss of body weight in winter. We previously found that histamine 3 receptor (H3R) mRNA in the posterior hypothalamu...

Loss of prokineticin receptor 2 signaling predisposes mice to torpor (2008)
Journal Article

The genes encoding prokineticin 2 polypeptide (Prok2) and its cognate receptor (Prokr2/Gpcr73l1) are widely expressed in both the suprachiasmatic nucleus and its hypothalamic targets, and this signaling pathway has been implicated in the circadian re...

Role of VGF-derived peptides in the control of food intake, body weight and reproduction (2008)
Journal Article

VGF is a 68-kDa polypeptide synthesized in neuronal and neuroendocrine cells. It is cleaved into a number of smaller peptides which are stored in dense core vesicles and are likely to be secreted products. The VGF gene is expressed abundantly in the...

VGF-derived peptide, TLQP-21, regulates food intake and body weight in Siberian hamsters (2007)
Journal Article

The Siberian hamster survives winter by decreasing food intake and catabolizing abdominal fat reserves, resulting in a sustained, profound loss of body weight. VGF gene expression is photoperiodically regulated in the hypothalamus with significantly... Read More about VGF-derived peptide, TLQP-21, regulates food intake and body weight in Siberian hamsters.

Hypothalamic thyroid hormone catabolism acts as a gatekeeper for the seasonal control of body weight and reproduction (2007)
Journal Article

Seasonal adaptations in physiology exhibited by many animals involve an interface between biological timing and specific neuroendocrine systems, but the molecular basis of this interface is unknown. In this study of Siberian hamsters, we show that th... Read More about Hypothalamic thyroid hormone catabolism acts as a gatekeeper for the seasonal control of body weight and reproduction.

Chronic subcutaneous administration of kisspeptin-54 causes testicular degeneration in adult male rats (2006)
Journal Article

The kisspeptins are KiSS-1 gene-derived peptides that signal through the G protein-coupled receptor-54 (GPR54) and have recently been shown to be critical regulators of reproduction. Acute intracerebroventricular or peripheral administration of kissp... Read More about Chronic subcutaneous administration of kisspeptin-54 causes testicular degeneration in adult male rats.

Neuromedin U partially mediates leptin-induced hypothalamo-pituitary adrenal (HPA) stimulation and has a physiological role in the regulation of the HPA axis in the rat (2006)
Journal Article

Intracerebroventricular (ICV) administration of the hypothalamic neuropeptide neuromedin U (NMU) or the adipostat hormone leptin increases plasma ACTH and corticosterone. The relationship between leptin and NMU in the regulation of the hypothalamo-pi...

Hypothalamic cocaine- and amphetamine-regulated transcript (CART) and agouti-related protein (AgRP) neurons coexpress the NOP1 receptor and nociceptin alters CART and AgRP release (2005)
Journal Article

Nociceptin or orphanin FQ (N/OFQ) and its receptor NOP1 are expressed in hypothalamic nuclei involved in energy homeostasis. N/OFQ administered by intracerebroventricular or arcuate nucleus (ARC) injection increases food intake in satiated rats. The...

Neuromedin U has a physiological role in the regulation of food intake and partially mediates the effects of leptin (2005)
Journal Article

Intracerebroventricular (ICV) administration of Neuromedin U (NMU), a hypothalamic neuropeptide, or leptin, an adipostat hormone released from adipose tissue, reduces food intake and increases energy expenditure. Leptin stimulates the release of NMU... Read More about Neuromedin U has a physiological role in the regulation of food intake and partially mediates the effects of leptin.

Galanin-Like Peptide Stimulates the Release of Gonadotropin-Releasing Hormone in Vitro and May Mediate the Effects of Leptin on the Hypothalamo-Pituitary-Gonadal Axis (2004)
Journal Article

Leptin regulates the hypothalamo-pituitary-gonadal axis in relation to nutritional status. The mechanism through which leptin mediates its effects on neuroendocrine reproductive circuits remains unclear. Galanin-like peptide (GALP) is a recently iden...

Paraventricular nucleus administration of calcitonin gene-related peptide inhibits food intake and stimulates the hypothalamo-pituitary-adrenal axis (2003)
Journal Article

Calcitonin gene-related protein (CGRP) inhibits food intake and stimulates the hypothalamo-pituitary-adrenal (HPA) axis after intracerebroventricular injection in rats. However, the hypothalamic site and mechanism of action are unknown. We investigat...
