Abstract

Objective: To explore the intervention effects of oral active AdipoRon on liver oxidative stress in type 2 diabetic mice, which provides basic data for clinical application.

Methods: Thirty-two healthy male C57BL/6 mice were divided into 4 groups:normal group (NC, n=8), diabetes mellitus group (DM, n=8), high dose AdipoRon treatment group (DM + H, n=8) and low dose AdipoRon treatment group (DM + L, n=8). Following six weeks high fat feed, mice of DM, DM + H and DM + L were intraperitoneally injected with 40 mg/kg streptozocin (STZ), leading to type 2 diabetes. Afterwards, DM + H group and DM + L group were continuously treated with high dose and low doses of oral AdipoRon respectively for 10 days, following which, related biochemical indicators were detected. Western blot method was used to detect the p-IRS-1 protein expression in liver tissue and RT-PCR method to detect PDX-1 mRNA expression in the pancreas.

Results: The blood glucose of DM group was obviously higher than that of NC group (P < 0.05). Compared to that of DM group, blood glucose of DM + H group as well as DM + L group was significantly lower. Activity of superoxide dismutase (SOD), catalase (CAT) in liver tissue of DM mice was significantly lower than that of NC group (P < 0.05); activity of malondialdehyde (MDA) and nitric oxide synthase (NOS) in DM group significantly higher than that of NC group (P < 0.05); activity of SOD and CAT in DM + L group and DM + H group obviously higher than DM group (P < 0.05); activity of MDA and NOS in DM + L group and DM + H group significantly lower than DM group (P < 0.05). And the p-IRS-1 protein expression in liver tissue and PDX-1 mRNA level in pancreas increased significantly (P < 0.05).

Conclusions: Oral active Adi-poRon which reduced the blood glucose levels of mice had a certain intervention effect on liver tissue oxidative stress in type 2 diabetes mice.

Keywords: AdipoRon; liver; oxidative stress; type 2 diabetes in mice.
