Abstract:
AIM:To study the dynamic alteration of low-density lipoprotein receptor ( LDLr) expression after exposure to hepatocyte growth factor (HGF) in human Tenon's capsule fibroblasts (HTFs).METHODS: HTFs were stimulated with HGF at different concentrations (0, 10, 20, 40, 80 and 160μg/L) for 12, 24, and 48 h.The viability of HTFs was analyzed by MTT assay .The expression of LDLr at mRNA and protein levels were analyzed by real-time PCR and Western blot .RESULTS:The expression of LDLr at mRNA and protein levels was positively correlated with the viability of HTFs.HGF promoted the viability of HTFs in a time-and concentration-dependent manner .At the same time , HGF pro-moted the expression of LDLr in the same manner .CONCLUSION:Exposure of HTFs to HGF induces LDLr expression at high level , suggesting that over-expression of LDLr on the HTFs may be a target receptor for controlled drug delivery , par-ticularly in anti-scarring therapy after glaucoma filtration surgery .
