摘要:

背景:细胞铁的外向转运是由铁调素调节的。铁调素的表达受机体信号因子的影响,如血清铁水平、促红细胞生成素、炎症、低氧、氧化应激等。这些刺激通过肝实质细胞表面的组织相容性Ⅰ型跨膜糖蛋白HFE,转铁蛋白受体1,2,铁调素调节蛋白激活各种信号通路,包括BMP-SMAD、JAK-STAT 和HIF1通路,进而改变铁调素基因的转录,调节铁调素的表达水平,但调节铁调素表达的分子机制还不明确。
目的:从影响铁调素表达的信号因子及信号通路两方面入手,总结并分析铁调素表达的调节机制。
方法:由第一作者通过计算机检索NCBI和SpringerLink(2000/2010)英文数据库,检索词为“Hepcidin,Hemochromatosis,Hemojuvelin,BMP signaling pathway,HFE,TfR1,TfR2”。分别从影响铁调素表达的信号因子及参与其表达调控的信号通路两方面进行总结,介绍近年来在铁调素表达调控机制方面的最新研究进展。
结果与结论:共检索到210篇文章,按纳入和排除标准对文献进行筛选,共纳入37篇文章。结果表明铁调素的表达受机体信号因子的影响,如肝实质细胞表面的遗传性血色素沉着症侯选基因、转铁蛋白受体1,2等,可通过激活各种信号通路,包括BMP-SMAD,JAK-STAT 和HIF1通路,进而改变铁调素基因的转录,并调节其表达。

Abstract:

BACKGROUND: The cellular iron efflux is modulated by hepcidin derived by liver and this peptide is now regarded as the central regulator of body iron homeostasis. Hepcidin expression is influenced by regulators such as iron store, the rate of erythropoiesis, inflammation, hypoxia and oxidative stress. These regulators control the content of hepcidin by proteins on hepatocyte, such as HFE, transferrin receptor 2, hemojuvelin and the IL-6R and so on. These proteins activate various cell signal transduction pathways, including the BMP-SMAD, JAK-STAT and HIF1 pathways. As a result, the expression of hepcidin is altered. However, the detail molecular mechanism of hepcidin expression remains unclear.
OBJECTIVE: To summarize the regulatory mechanism of hepcidin from the aspects of signal factor and signal pathway.
METHODS: Literatures in NCBI and SpringerLink databases from 2000 to 2010 were searched by the first author using key words of “hepcidin, hemochromatosis, hemojuvelin, BMP signaling pathway, HFE, transferrin receptor 1, transferrin receptor 2”. The latest research regarding regulatory mechanism of hepcidin was analyzed from the aspects of signal factor and signal pathway.
RESULTS AND CONCLUSION: Totally 210 papers were searched by computer, and 37 documents were included according to inclusive and exclusive criteria. The results showed that hepcidin expression was influenced by signal factors such as hereditary hemochromatosis, transferrin receptor 1, and transferrin receptor 2. These proteins activate various cell signal transduction pathways, including the BMP-SMAD, JAK-STAT and HIF1 pathways. As a result, the expression of hepcidin was altered.
