Exercise performance is not improved in mice with skeletal muscle deletion of natriuretic peptide clearance receptor.

ABSTRACT: Natriuretic peptides (NP), including atrial, brain, and C-type natriuretic peptides (ANP, BNP, and CNP), play essential roles in regulating blood pressure, cardiovascular homeostasis, and systemic metabolism. One of the major metabolic effects of NP is manifested by their capacity to stimulate lipolysis and the thermogenesis gene program in adipocytes, however, in skeletal muscle their effects on metabolism and muscle function are not as well understood. There are three NP receptors (NPR): NPRA, NPRB, and NPRC, and all three NPR genes are expressed in skeletal muscle and C2C12 myocytes. In C2C12 myocytes treatment with either ANP, BNP, or CNP evokes the cGMP signaling pathway. Since NPRC functions as a clearance receptor and the amount of NPRC in a cell type determines the signaling streng
