Skeletal muscle is the principal tissue responsible for insulin-stimulated glucose disposal and is thus the major site of peripheral insulin resistance. Urocortin 2 (Ucn2), a corticotropin releasing factor (CRF) family member and the type 2 CRF receptor (CRFR2) are highly expressed in skeletal muscle. To determine the physiological role of Ucn2, we generated mice deficient in this peptide. Using glucose and insulin tolerance tests and hyperinsulinemic euglycemic glucose clamp ...
