促红细胞生成素(EPO)的生成是由低氧诱导因子(HIF)调节,而HIF又是被脯氨酰羟化酶(PH)所调节。 在常氧状态下,HIF-PH的活动将会快速降解HIF;而在低氧条件下,HIF-PH的活动被抑制,使得1)HIF能够积累并刺激内源EPO的生成;2)上调运铁蛋白受体的表达;3)增加红细胞对铁的吸收;4)促进富含血红蛋白的红细胞成熟 [3]。 HIF-PH抑制剂的原理是通过抑制脯氨酰羟化酶(PH)的作用,从而固定肾脏和肝脏中的HIF,增加内源促红细胞生成素的生成 [3] …
缺氧诱导因子(HIF) 是一种关键转录因子,主要参与细胞调节和氧输送效率。 其初步状态包括组成性表达的核结合β 亚基和胞浆α亚基的三种亚型(HIF-1α、HIF-2α 和HIF-3α)。 HIF-1α 和HIF-2 α是低氧防御机制的主要调节因子, 通过刺激多种基因增强氧输送。

In this review, I describe the process of molecular cloning of HIF and HIF-PH, which explains the induction of EPO expression by hypoxia; the development of HIF-PH inhibitors (HIF-PHIs) that artificially activate HIF by inhibiting HIF-PH; medical interventions that utilize HIF-PHIs; and the implications and significance of these interventions ...
Hypoxia-inducible factor prolyl hydroxylase inhibitors: a paradigm ...
Introduction: The hypoxia-inducible factor prolyl hydroxylase (HIF-PH) pathway is responsible for regulating the biosynthesis of erythropoietin (EPO) and maintaining iron homeostasis. Investigational drugs that target the HIF-PH pathway are promising alternatives for treating anemia in Chronic Kidney Disease (CKD).
