Cortistatin-29 (1-13) is a neuropeptide and cleavage product of cortistatin-29 , which is a cleavage product of procortistatin. Cortistatin-29 (1-13) corresponds to the first 13 amino acids of cortistatin-29.
Adrenomedullin (13-52) is a truncated form of adrenomedullin (1-52) . It induces nitric oxide-dependent relaxation of and inhibits release of angiotensin II and endothelin-1 from isolated rat aorta. In vivo, adrenomedullin (13-52) decreases mean arterial pressure (MAP) in spontaneously and renal hypertensive rats in a dose-dependent manner. Adrenomedullin (13-52) (10-3,000 ng per animal) reverses increases in lobar arterial pressure induced by U-46619 in a dose-dependent manner in cats but has no effect on basal lobar arterial pressure or systemic arterial pressure. It also potentiates inflammatory edema and neutrophil accumulation in rats.
Parathyroid hormone (PTH) (1-13) is an N-terminal fragment of PTH (1-34) . In vivo, PTH (1-13) (0.003-1 μmol/kg) increases mean arterial pressure (MAP) in anesthetized rats.
