Improvement effect and mechanism of paeoniflorin on glucose metabolism, inflammation and oxidative stress in rats with gestational diabetes mellitus
To explore the effect of paeoniflorin on glucose metabolism, inflammation and oxidative stress in rats with gestational diabetes mellitus (GDM) and its potential mechanism based on nuclear factor-erythroid 2-related factor 2 (Nrf2)/heme oxygenase-1 (HO-1)/nicotinamide adenine dinucleotide phosphate:quinone oxidoreductase 1 (NQO1) signaling pathway.
METHODS
2
The female rats fed with high fat and high sugar diet and the male rats fed with an ordinary diet were caged, the successfully conceived rats were collected, and streptozotocin was injected intraperitoneally once to induce the GDM model. The successfully modeled rats were randomly divided into the model group, metformin hydrochloride group (200 mg/kg metformin by gavage), paeoniflorin low-, high-dose groups (45, 90 mg/kg paeoniflorin by gavage, respectively), paeoniflorin+ML385 group (90 mg/kg paeoniflorin by gavage and intraperitoneal injection of 30 mg/kg Nrf2 inhibitor ML385), with 12 rats in each group; in addition, another 12 conceived rats fed with an ordinary diet were selected as the control group. The rats in each drug group were given the corresponding drug/normal saline, once a day, for 2 consecutive weeks. Glucose metabolism indexes [fasting blood glucose (FBG), fasting insulin (FINS), insulin resistance index (HOMA-IR)], serum inflammatory factors [interleukin-6 (IL-6), tumor necrosis factor-α (TNF-α)] and renal tissue oxidative stress indexes [superoxide dismutase (SOD), malondialdehyde (MDA), glutathione peroxidase (GSH-Px)] were detected; the pathological changes of renal tissue were observed, and the protein expressions of Nrf2, HO-1 and NQO1 in renal tissue were detected.
RESULTS
2
Compared with the control group, the renal tissue lesions of the model group were obvious, including glomerular atrophy, edema degeneration of renal tubular epithelial cells and a large number of inflammatory cell infiltration; the levels of FBG and FINS, HOMA-IR, the levels of IL-6 and TNF-α in serum, and the level of MDA in renal tissue were significantly increased (
P
<0.05), while the levels of SOD and GSH-Px and the protein expressions of Nrf2, HO-1 and NQO1 in renal tissue were significantly decreased (
P
<0.05). Compared with the model group, the renal tissue lesions of rats in paeoniflorin low-dose and high-dose groups were reduced, the above quantitative indexes were significantly improved, and the improvement effect was better in high-dose group (
P
<0.05), while ML385 could significantly reverse the improvement effect of paeoniflorin on the above indexes (
P
<0.05).
CONCLUSIONS
2
Paeoniflorin can improve the abnormal glucose metabolism, inflammation and oxidative stress damage of renal tissue in GDM rats, which may be related to the activation of Nrf2/HO-1/NOQ1 signaling pathway.
