Background/objectives: Fibroblast growth factor 21 (FGF21) is a potent hormone known to reduce glycaemia and improve insulin resistance with anti-obesity effects. Although mainly secreted in the liver, adipose tissue is considered an important target for its function. Whilst FGF21 has been shown to be expressed in murine adipose tissue, studies in human adipose tissue are lacking. Therefore our aim was to examine the expression of FGF21, FGF21 receptor-1 (FGFR1), βKlotho ...

Background/objectives: Irisin is a novel myokine, released predominantly by skeletal muscle. Peripheral action of irisin improves glucose homeostasis, increases energy expenditure and induces browning of adipocytes, with therapeutic potential for use in weight loss. However, there are no human studies on the central role of irisin in the regulation of appetite or energy expenditure. This study sought to examine the potential central role of irisin, by demonstrating irisin in h...

Background: Adipogenesis is a key process leading to adipose tissue (AT) expansion. However, managing this event is critical to limit excessive fat accumulation and disease risk. Adipogenesis appears controlled in part, through Wnt10b signalling which reduces adipogenesis via inhibiting CCAAT/enhancer-binding protein alpha (CEBPα) although the molecular mechanism remains unclear.Aims: Abdominal subcutaneous AT (AbdSc AT) was collected from a, non-di...

Background/aim: The global obesity epidemic has promoted a search for novel solutions. One approach is through modification of eating-related behaviours. Our aim was to explore the effects of meal duration on energy expenditure, appetite and excursions of molecules associated with insulin sensitivity in the post-prandial phase.Methods: Normoglycaemic, pre-menopausal, Caucasian obese women (n=8) were recruited from the Obesity clinic at Warwicksh...
