- W3028725643 abstract "Background The injury or surgery of cornea cause the proliferation of corneal stromal cells and scar formation.Recent research showed that cureumin can obviously reduce the degree of fibrosis of tissue.But if curcumm play inhibitory effect on corneal keratocytes fibrosis is rarely reported.Objecttve This studv was to investigate the effect of curcumin on the transformation of corneal keratocytes into fibroblasts in vitro and further explore the antifibrotic effect of curcumin on corneal keratocytes.Methods The murine corneal keratocytes from 150 BALB/c mice were isolated and primary culture in DMEM culture medium containing 10% fetal bovine serum and then divided into blank control group(inducer group,CG),low-dose group(CG+7.5 mg/L curcumin),mediumdose group(CG+10.0 mg/L curcumin),high-dose group(CG+12.5 mg/L curcumin),non-inducer group.Seven days following intervention,the expression of cell markers such as keratocan,aldehyde dehydrogenase(ALDH),decorin and fibronectin-1 in keratocytes were analyzed by RT-PCR.The effect of curcumin on cultured murine corneal keratocytes proliferation was evaluated by MTS technique.The expression of fibronectin-1 in murine cornea was investigated by immunofluorescence assay.Results The primarily cultured keratocytes showed tlIe fusiform-like shape with the abundant cytoplasm and big nuclei.In the presence of curcumin,the mRNA levels of keratocan and ALDH were down-regulated and those of CD90 and decorin were up-regulated,showing the significantly differences with the increase of dose(P<0.05),but the expression pf fibronectin-i was not obviously changed with the alteration of dose of curcumin. MTS showed that the inhibitory rates of curcumin on keratocytes in 10.0 mg/L and 2. 5 mg/L groups were enhanced in comparison with 7.5 mg/L group, showing statistically significant difference among three groups( F = 956.00, P<0.05). The expression of fibronectin-1 was found in the corneal keratocytes with the red fluorescence in stroma. Conclusion Curcumin can inhibit the fibrosis of corneal keratoeytes in a dose-dependent manner. These results offer a preliminary theoretical basis for the application of curcumin in controlling corneal scar formation during wound healing.Key words: Curcumin; Keratocyte; Fibroblast; Fibrosis" @default.
