reported that high glucose‐induced CARM1 expression increases apoptosis in retinal pigment epithelial (RPE) cells through asymmetric dimethylation of H3R17, and reducing CARM1 expression can be used to prevent RPE apoptosis in the progression of diabetic retinopathy (Kim, Park, et al. 2014). This evidence concerns the gene CARM1 and diabetic retinopathy.
