Carvacrol alleviates oxidative stress damage in rats with diabetic nephropathy via the SIRT1/FOXO1 pathway
To investigate the mechanism of carvacrol alleviating oxidative stress damage in rats with diabetic nephropathy (DN) via the SIRT1/FOXO1 pathway.
Methods
2
A rat model of DN was established by high-fat diet and intraperitoneal injection of streptozotocin,and then DN rats were divided into control group,model group,L-XQF group(5 mg/kg),M-XQF group(10 mg/kg),and L-XQF group(20 mg/kg). Fasting blood glucose(FBG),blood urea nitrogen(BUN),serum creatinine(SCr),and urinary microprotein (U-mAlb) were measured. After the rats were sacrificed and renal tissue samples were collected,HE staining and Masson staining were used to observe the pathological changes and fibrosis of renal tissue;ELISA was used to measure the levels of malondialdehyde (MDA),superoxide dismutase(SOD),and glutathione peroxidase(GSH-Px) in renal tissue; Western blot was used to measure the expression levels of SIRT1/FOXO1 pathway-related proteins.
Results
2
Carvacrol reduced the levels of FBG,BUN,SCr,U-mAlb,and MDA,improved the pathological injury and fibrosis of renal tissue,and increased the content of SOD and GSH-Px and the levels of SIRT1 and FOXO1 proteins.
Conclusion
2
Carvacrol may inhibit oxidative stress in renal tissue of DN rats via the SIRT1/FOXO1 pathway,thereby alleviating renal injury and improving renal fibrosis.
