MC4R-dependent suppression of #appetite by bone-derived #lipocalin 2
http://www.nature.com/nature/journal/vaop/ncurrent/full/nature21697.html
Loss- and gain-of-function experiments in mice demonstrate that osteoblast-derived LCN2 maintains glucose homeostasis by inducing insulin secretion and improves glucose tolerance and insulin sensitivity. In addition, osteoblast-derived LCN2 inhibits food intake. LCN2 crosses the blood–brain barrier, binds to the melanocortin 4 receptor (MC4R) in the paraventricular and ventromedial neurons of the hypothalamus and activates an MC4R-dependent anorexigenic (appetite-suppressing) pathway. These results identify LCN2 as a bone-derived hormone with metabolic regulatory effects, which suppresses appetite in a MC4R-dependent manner, and show that the control of appetite is an endocrine function of bone.

Aims To evaluate the effect of oral semaglutide on energy intake and appetite in subjects with type 2 diabetes (T2D). Materials and methods In this randomised, double‐blind, placebo‐controlled, two‐period cross‐over trial, 15 subjects with T2D received 12 weeks’ treatment with once‐daily oral semaglutide (4‐week dose‐escalation from 3 to 7 to 14 mg) followed by placebo, or vice versa. Energy intake was measured during an ad …
