Another role that well studied in cardiovascular diseases is lncRNA ANRIL (antisense non-coding RNA in the INK4 locus), which regulated VEGF expression and function in diabetic retinopathy via miR-200b, and EZH2 (Enhancer of Zeste 2 Polycomb Repressive Complex 2 Subunit) of the PRC2 (Polycomb Repressive Complex 2) complex [23]. Here, CDKN2A is linked to diabetic retinopathy.
