OBJECTIVE: To investigate the effects of the downregulation of AGER by miRNA-185-3p on renal function in diabetic nephropathy (DN) mice.

MATERIALS AND METHODS: Mice were divided into normal, model, NC, miR-185-3p mimic, si-AGER, and miR-185-3p mimic + si-AGER groups. Eight weeks following the establishment of the model, various indicators were assessed.

RESULTS: Compared to control groups, miR-185-3p expression, body weight, superoxide dismutase (SOD) content, catalase (CAT) content, proliferation, S-phase ratios, and proliferating cell nuclear antigen (PCNA) expression were significantly lower in all experimental groups, whilst AGER expression, water intake, food intake, urine volume, urine protein content, serum creatinine (Scr), Blood Urea Nitrogen (BUN), MDA content, G0/G1 status, and rates of apoptosis were significantly higher (all p<0.05). Compared to the model group, miR-185-3p mimics, si-AGER, and miR-185-3p mimic + si-AGER groups had a significantly higher SOD content, CAT content, proliferation, S phase ratios, PCNA expression and lower AGER expression, water intake, food intake, urine output, urine protein, Scr, BUN, MDA content, G0/G1 ratios, and apoptosis rates (all p<0.05). In addition, the effects of the miR-185-3p mimics + si-AGER were superior to miR-185-3p mimics and si-AGER monotherapy groups (both p<0.05).

CONCLUSIONS: MiR-185-3p inhibits AGER, downregulates AGER expression, and improves renal function in DN mice.
