Differential effects of Calca-derived peptides in male mice with diet-induced obesity.

ABSTRACT: Key metabolic hormones, such as insulin, leptin, and adiponectin, have been studied extensively in obesity, however the pathophysiologic relevance of the calcitonin family of peptides remains unclear. This family includes calcitonin (CT), its precursor procalcitonin (PCT), and alpha calcitonin-gene related peptide (αCGRP), which are all encoded by the gene Calca. Here, we studied the role of Calca-derived peptides in diet-induced obesity (DIO) by challenging Calcr-/- (encoding the calcitonin receptor, CTR), Calca-/-, and αCGRP-/- mice and their respective littermates with high-fat diet (HFD) feeding for 16 weeks. HFD-induced pathologies were assessed by glucose tolerance, plasma cytokine and lipid markers, expression studies and histology. We found that DIO in mice lacking the CTR resulted
