Large quantitative effect of melanocortin-4 receptor gene mutations on body mass index
1 Oct 2004
Abstract excerpt
The melanocortin-4 receptor gene ( MC4R ) is involved in central energy homeostasis and body weight regulation. Both endogenous anorexigenic and orexigenic ligands bind to the receptor.1 Under normal conditions, the anorexigenic tone prevails as revealed by the fact that Mc4r knock-out mice2 develop elevated body weight. Mc4r−/− mice show higher food intake but a similar metabolic rate and similar decreased...
