TGFB1 and age-related macular degeneration: Specifically, these studies described: a) miR-204/211 involvement in maintaining the RPE phenotype [23]; b) miR-34a maintaining RPE cells quiescent and stationary [18]; c) differentially expressed miRNAs in TGFβ-induced EMT in RPE cells [24], and miR-124 involvement in this process [25]; e) the role of miR-23a [26] and miR-184 [27] in age-related macular degeneration.
