Abstract: @@ Traditionally, it was believed that the natriuretic peptide family (NPs) was composed of four natural peptides, i.e., atrial natriuretic peptide (ANP), brain natriuretic peptide (BNP), C-type natriuretic peptide (CNP) and urodilatin. All of them have the same 17-amino acid ring connected by bisulfate bond, which is essential for their biological activity.1 There are C-terminal and N-terminal tails on the ring. Each peptide encoded by an independent gene has its own tissue specificity and regulation mechanism. It is now suggested that beside the four traditional peptides, their precursors and the peptide fragments released by the activation or hydrolysis of the precursors, such as precursor of ANP and N-terminal proANP (NTANP), precursor of BNP and N-terminal proBNP (NTBNP) are also NPs. Furthermore, an artificially synthesized NP, vasonatrin peptide, is also a new member of NP family. In fish like eel, another peptide named ventricular natriuretic peptide was found. We now have a review on the clinical significance of NTBNP.
