摘要: Pleckstrin同源域家族A成员1(PHLDA1)是一种促凋亡因子,也是代谢性疾病的关键调节剂。在肥胖相关疾病中,PHLDA1可以通过抑制固醇调控元素结合蛋白1(SREBP-1)的表达而减少肝三酰甘油的产生,也可通过抑制过氧化物酶体增殖剂激活受体γ(PPARγ)减少脂肪形成,但在心脑血管疾病中,却通过抑制PPARγ而增加血管钙化,刺激内质网应激反应(ERS)及线粒体功能障碍的产生,进而加重心脑缺血再灌注损伤。PHLDA1所表现出的双重作用也在肿瘤中得到印证。总之,PHLDA1作为多功能因子通过多种机制发挥不同作用。

Abstract: Pleckstrin homology-like domain family A member 1 (PHLDA1) is a pro-apoptotic factor as well as a key regulator of metabolic diseases. In obesity-related diseases, PHLDA1 can reduce liver triglyceride production through inhibition of the expression of sterol regulatory-element binding proteins-1 (SREBP-1), and reduce fat synthesis through inhibition of peroxisome proliferator-activated receptor γ (PPARγ). However, in cardiovascular diseases, PHLDA1 increases vascular calcification, dysfunction, thereby aggravates ischemia-reperfusion injury in the heart and brain. The dual role of PHLDA1 has also been confirmed in tumors. In summary, PHLDA1, as a multifunctional factor, plays different functional roles through various mechanisms.

Key words: pleckstrin homology-like domain family A member 1 (PHLDA1), endoplasmic reticulum stress, obese, cardiovascular diseases
