Research Abstract |
We found increased periostin expression in the vitreous of patients with proliferative diabetic retinopathy (PDR). Immunohistochemical analysis showed colocalization of periostin and a-SMA in PDR-ERMs. In vitro, periostin increased proliferation, adhesion, migration, and collagen production in RPE cells. Periostin blockade suppressed migration and adhesion induced by TGFb2. In vivo, periostin inhibition had the inhibitory effect on experimental retinal fibrovascular formartion without affecting the viability of retinal cells. These results identified periostin as a pivotal molecule for ERM formation as well as a promising therapeutic target for PDR.
