KCNQ1OT1 and diabetic retinopathy: Reportedly, lncRNA KCNQ1-overlapping transcript 1 (KCNQ1OT1) was involved in the development of diabetic retinopathy (DR) by promoting proliferation and angiogenesis of hRECs through sponging miR-1470; and knockdown of KCNQ1OT1 induced apoptosis and inhibited cell proliferation in HG (Shao et al., 2019).
