Departments of Internal Medicine and Pediatric Endocrinology, Erasmus MC, Rotterdam, The Netherlands
Mol Biol Rep 41:7967-72. 2014..Our data describe a rare homozygous inactivating mutation in the first intra-cellular loop of MC4R that markedly impairs its function and is associated with early-onset obesity and hyperphagia...
- Des-acyl ghrelin analogs prevent high-fat-diet-induced dysregulation of glucose homeostasisPatric J D Delhanty
