Long non-coding ribonucleic acid ATP2B1-AS1 modulates endothelial permeability through regulating the miR-4729-IQGAP2 axis in diabetic retinopathy.

ABSTRACT:

Aims/introduction

Mounting evidence shows that long non-coding RNAs (lncRNAs) are important to modulate the biological process of diabetic retinopathy (DR). We aimed to investigate the role of lncRNAs in DR and elucidate the exact mechanism.

Materials and methods

Real-time quantitative polymerase chain reaction was carried out to distinguish the lncRNA ATPase plasma membrane Ca²⁺ transporting 1 antisense RNA 1 (ATP2B1-AS1) expression in DR patients and HG-treated human retinal endothelial cells (HRECs). Dual-luciferase reporter system was used to verify that ATP2B1-AS1 could act as a microRNA (miR)-4729 sponge, and miR-4729 could bind to 3'UTR of IQ motif-containing GTPase-activating protein 2 (IQGAP2).
