Retinal Src homology region 2-containing protein tyrosine phosphatase 2 silencing alleviates diabetic retinopathy via suppressing inflammatory response and oxidative stress by regulating Yes-associated protein 1 activity.

ABSTRACT: Diabetic retinopathy (DR) is the prevalent microvascular complication of diabetes mellitus (DM), and it may lead to permanent blindness. The previous publication has indicated that both inflammatory response and oxidative stress are critical factors involved in DR progression, however, the accurate regulatory mechanism remains to be revealed. Src homology region 2 (SH2)-containing protein tyrosine phosphatase 2 (SHP2), a member of the protein tyrosine phosphatase family, was reported to play a role in diabetic nephropathy, whereas its function in DR was unknown and required further exploration. The level of phosphorylated, not the total, SHP2 increased in the retinas of rats with streptozotocin injection-induced DM. Further, the intravitreal injection of SHP2 shRNA lentivirus alleviated re
