AIM： To investigate the mechanism of AngRem104 - mediated regulation of flbronectin gene in human mesangial cells. METHODS： A series of deleted FN promoter sequences was constructed, which fuse to a luciferase reporter gene, and then the potential active regions that respond to AngRem104 in the upstream regulatory sequence of human FN gene was screened by detecting the luciferase activity of promoter - reporter gene. RESULTS： The detection of relative luciferase activity revealed that there was no significant differences when the HMC were transfected with FN122 - reporter gene together with sense AngRem104 construct, but the luciferase activity significantly increased when transfection of FN507 - reporter gene construct together with sense AngRem104 construct. However; no increase in luciferase activity was observed when transfection of FN1280 - reporter gene construct together with sense AngRem104 construct. The potential regulatory region responds to AngRem104 is in the upstream sequence （ - 122 to - 507） of human FN gene. CONCLUSION： Our preliminary study provided the evidence that AngRem104 may mediate the transcription of the FN gene via the activation of its oromoter.
