FGF5 and diabetic retinopathy: Transfection of miR-145-5p inhibitor (inhibits fibroblast growth factor 5, FGF5) in RGC-5 cells exposed to high glucose, as in an in vitro diabetic retinopathy model, produces a decrease in TNF-α and IL-6 on these cells and also reduces apoptosis, keeping an elevated cell proliferation capacity [122].
