丹玉和脉颗粒调控Nrf2/HO-1信号通路改善高血压大鼠肾损伤的研究
Investigating the effect of Danyu Hemai Granule(丹玉和脉颗粒)on renal injury in hyperten-sive rats via regulating the Nrf2/HO-1 signaling pathway
摘要
Abstract
Objective To observe the therapeutic effect of Danyu Hemai Granule(丹玉和脉颗粒,DYHMG)in spontaneously hyper-tensive rats(SHR)and explore its possible protective mechanism in Chinese herbal medicine(CHM)based on the Nrf2/HO-1 signa-ling pathway.Methods Eighteen 5-week-old male SHRs were adaptively fed for one week and then randomly assigned to three groups:the SHR group(gavage with distilled water),the DHG group(gavage with DHG at 42 g crude drug·kg-1 per day)and the valsartan group(gavage with valsartan at 30 mg·kg-1 per day),with 6 rats in each group.Six age and sex matched WKY rats gavaged with distilled water served as the control.All rats were gavaged once a day for 10 weeks,with blood pressure measured every 2 weeks.At the end of the 10th week,the renal tissues were collected.Pathological changes in the renal tissues were observed by HE and Masson staining.Western blot(WB)was used to detect the protein expressions of Nrf2,HO-1,and GPX4 in the renal tissues.Results Com-pared with the WKY group,the SHR group showed significantly elevated systolic blood pressure(P<0.001),enlarged glomerular vol-ume,vacuolization of renal tubular epithelial cells,and marked collagen fiber hyperplasia.Protein expressions of Nrf2,HO-1 and GPX4 in the renal tissues of rats in the SHR group were significantly decreased(P<0.001).Compared with the SHR group,DYHMG could lower the blood pressure(P<0.05),alleviated renal tubular vacuolization,ameliorated collagen hyperplasia,and significantly in-creased Nrf2 and HO-1 expression in the renal tissues(P<0.05).Conclusion DYHMG can reduce systolic blood pressure in SHRs,mitigate renal pathological damage and oxidative stress injury,and its mechanism may be associated with the regulation of the Nrf2/HO-1 pathway.关键词
