CPSF1 mediates retinal vascular dysfunction in diabetes mellitus via the MAPK/ERK pathway.

Abstract:

:This study investigated the expression and underlying molecular mechanism of CPSF1 in diabetic retinopathy. Streptozotocin (STZ)-induced Sprague-Dawley (SD) rats were employed as a diabetic model, and high-glucose (HG)-induced human retinal vascular endothelial cells (HRVECs)were used as an in vitro experimental model to explore the effect of CPSF1. The results showed that CPSF1 was downregulated in diabetic retinopathy (DR) tissues and HRVECs under HG conditions. Adeno-associated viral CPSF1 attenuated histological abnormalities of retinas. CPSF1 regulates the apoptosis, migration, and vascularisation of HRVECs under HG conditions in vitro. CPSF1 mediates retinal vascular dysfunction by suppressing the phosphorylation mechanism in the mitogen-activated protein kinase/extracellular-signal-regulated kinase (MAPK/ERK) pathway in DR. In conclusion, CPSF1 may be associated with the development of DR, and upregulated CPSF1 alleviates apoptosis and migration via MAPK/ERK pathway.
