| Research Abstract |
When corneal fibroblast (keratocyte) was stimulated by TGF-beta, the keratocytes showed myofibroblast-like morphology. In addition, the expression of integrin alpha11 (ITGA11), alpha-smooth muscle actin (alpha-SMA), fibronectin in keratocytes was increased by TGF-beta treatment. Sensitivity to TGF-beta was up-regulated in the cells constitutively expressing ITGA11 or calcium-and integrin-binding protein 1. It was suggested that ITGA11 and CIB1 could be the target protein of the organ fibrosis treatment.Furthermore, we found that the green tea component epigallocatechin-3-gallate (EGCG) binds to TGF-beta type II receptor and inhibits the action of TGF-beta.
