心房利钠利尿肽原不同肽段的生物学效应及其相互作用
Biologic effects of different fragments derived from pro-atria natriuretic peptide and their interactions
【摘要】 心房利钠利尿肽原(pro-atrial natriuretic peptide,proANP)在蛋白水解酶corin的作用下分解为众多小分子片段,包括氨基端前体片段(NT-proANP)、长效利钠利尿肽(long-acting natriuretic peptide,LANP)、血管舒张肽(vessel dilator)、利钾利尿肽(kaliuretic peptide,KP)、尿舒血管素(urodilatin)和羧基端的心房利钠利尿肽(atrial natriuretic peptide,ANP)等。近年发现这些活性片段不仅各自具有相对独立的生物学效应,而且相互作用,形成复杂的调节网络,在机体稳态维持中具有重要的生理和病理生理意义。
【Abstract】 The pro-atrial natriuretic peptide(pro-ANP) is degraded to multiple fragments by proteinase "corin",including N-terminal pro-ANP(1-98),long-acting natriuretic peptide(1-30),vessel dilator(31-67),kaliuretic peptide(79-98),atria natriuretic peptide(99-126),urodilation(95-126) and so on.These bioactive fragments not only display independent individual biological activities,but also interact with each other to form a complex regulation network.This regulatory network plays an important role in homeostasis of organism.
