Biochem/physiol Actions
纤溶酶原激活物抑制剂1 (PAI -1)参与介导细胞衰老。它在损伤期间与其他组织修复转录组一起上调。PAI-1水平升高被认为是与心肌梗死(MI)相关的风险之一。
纤溶酶原激活物抑制剂1（PAI-1）是丝氨酸蛋白酶抑制剂Serpin超家族的一员，可参与到细胞外基质重塑并涉及血管生成、趋化性、排卵和胚胎生成等过程。
纤溶酶原激活物抑制剂1（PAI-1）蛋白属于丝氨酸蛋白酶抑制剂的Serpin超家族。它是组织纤溶酶原激活物（tPA）和尿激酶（uPA）的主要抑制剂，并也是纤溶酶原的激活剂，因此可抑制纤维蛋白溶解过程。 PAI可参与到细胞外基质的重塑，并涉及血管生成、趋化性、排卵和胚胎生成等过程。 PAI-1在各种疾病状态中的水平都有所上升，如多种癌症形式、肥胖症和代谢综合征。
General description
纤溶酶原激活物抑制剂1 (PAI-1)或丝氨酸蛋白酶抑制剂E1 (SERPINE1)基因映射到人类染色体7q22.1。PAI-1在肝细胞、内皮细胞、平滑肌细胞、巨核细胞和脂肪细胞中产生。

The close relationship existing between aging and thrombosis has growingly been studied in this last decade. The age-related development of a prothrombotic imbalance in the fibrinolysis homeostasis has been hypothesized as the basis of this increased cardiovascular and cerebrovascular risk.
