Stimulator of Fe transport and brain iron metabolism / 中国组织工程研究

ABSTRACT

OBJECTIVE: In order to understand the effect of stimulator of Fe transport(SFT) on Fe metabolism and its abnormality(absence or overloading),this study reviews the research development of SFT at home and abroad and focused on the relationship among expression,structure,physiological function,expressing controlling and expressing abnormality with brain iron metabolism.DATA SOURCES Electronic literature search of NCBI related to SFT was performed using the terms "stimulator of iron transport" or "stimulator of Fe transport",and the language was restricted in English. And simultaneously CNKI database was searched with the word "brain iron metabolism" and"stimulator of Fe transport" in Chinese from January 1997 to October 2004.STUDY SELECTION Articles that reported the structure,expression regulation of SFT and its relationship to brain iron metabolism diseases were included.DATA EXTRACTION Twenty pieces of SFT-related literatures and 1300pieces of literatures related to brain iron metabolism were found,among which 21 pieces were included.DATA SYNTHESIS: From the 21 pieces of literatures,the structure,distribution,biological function,expression regulation of SFT and its relationship with brain iron metabolism were mainly discussed.CONCLUSION: SFT can stimulate both transferrin- and nontransferrin-bound iron uptake. The expression of SFT can be regulated transcriptionally and post-transcriptionally,mainly regulated in response to different cellular iron levels. So SFT plays an important role in brain iron metabolism.
