生化/生理作用

(Pyr1)-Apelin-13 是人血浆和心脏中的主要 apelin 形式,它对应于 Apelin-13,其 N 端具有翻译后修饰的焦谷氨酰基(pGlu,pE),而不是谷氨酰胺(Gln,Q)。(Pyr1)-Apelin-13 的 APJ 激动剂效力高于 Apelin-13(EC50 分别为 0.30 vs. 0.37 nM;在表达人 APJ 的 CHO 细胞培养物中诱导酸化)。(Pyr1)-Apelin-13 对人、小鼠、大鼠和牛具有反应性,并广泛用于研究培养物和动物体内(通过腹腔注射、静脉注射、鞘内注射) APJ 介导的细胞和生理功能。

Apelin is emerging as an important hormone regulator of cardiovascular homoeostasis and an important biomarker for heart failure. Apelin concentrations have historically been measured by immunoassays; however, reported apelin concentrations measured in healthy volunteers show a large disparity from a
