Non-alcoholic fatty liver disease (NAFLD) begins with lipid accumulation within hepatocytes, but the relative contributions of different macronutrients is still unclear. We investigated the impact of fatty acids, glucose and fructose on lipid accumul...

TLQP-21, a peptide encoded by the highly conserved vgf gene, is expressed in neuroendocrine cells and has been the most prominent VGF-derived peptide studied in relation to control of energy balance. The recent discovery that TLQP-21 is the natural a... Read More about Photoperiodic changes in adiposity increase sensitivity of female Siberian hamsters to systemic VGF derived peptide TLQP-21.

VGF (non-acronymic) was first highlighted to have a role in energy homeostasis through experiments involving dietary manipulation in mice. Fasting increased VGF mRNA in the Arc and levels were subsequently reduced upon refeeding. This anabolic role f...

Peripheral administration of prokineticin 2 potently reduces food intake and body weight in mice via the brainstem (2012)
Journal Article
Beale, K., Gardiner, J., Bewick, G., Hostomska, K., Patel, N., Hussain, S., …Dhillo, W. (2013). Peripheral administration of prokineticin 2 potently reduces food intake and body weight in mice via the brainstem. British Journal of Pharmacology, 168(2), 403-410. https://doi.org/10.1111/j.1476-5381.2012.02191.x

Background and Purpose Prokineticin 2 (PK2) has recently been shown to acutely reduce food intake in rodents. We aimed to determine the CNS sites and receptors that mediate the anorectic effects of peripherally administered PK2 and its chronic effect...

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