Kaempferol is a natural flavonoid with a wide range of pharmacological effects. The current study tested whether kaempferol prevents hypertension-induced renal remodelling in rats. During the 5 weeks of experiments, rats (<i>n</i> = 7/group) were administered <i>N</i><sub><i>ω</i></sub>-nitro-L-arginine methyl ester hydrochloride (L-NAME) (40 mg/kg/day) with either vehicle or kaempferol (20 mg/kg/day) or kaempferol (40 mg/kg/day) or lisinopril (5 mg/kg/day). <i>Results</i>. Kaempferol treatment alleviated haemodynamic changes occurring in hypertensive rats, including increases in systolic and diastolic blood pressure, pulse pressure, mean arterial pressure, and heart rate (<i>p</i> < 0.05). Kaempferol treatment prevented glomerular hypertrophy by reducing the increased glomerular cross-sectional area, glomerular tuft area, Bowman’s space area, glomerular volume, and the extent of renal tubulointerstitial fibrosis induced by hypertension (<i>p</i> < 0.05). Furthermore, animals in the L-NAME group showed elevated angiotensin-converting enzyme (ACE) activity and angiotensin II (Ang II) levels compared to those in the kaempferol-treated group (<i>p</i> < 0.05). Kaempferol treatment also reverted the elevations in levels of superoxide anions and malondialdehyde and reduced catalase and superoxide dismutase activity in hypertensive rats (<i>p</i> < 0.05). L-NAME-treated rats showed overexpression of angiotensin II receptor type 1 (AT1), nicotinamide adenine dinucleotide phosphate oxidase 4 (NOX4), and matrix metalloproteinase-9 (MMP-9) proteins; conversely, the expression of these proteins was reduced in the kaempferol-treated group (<i>p</i> < 0.05). <i>Conclusion</i>. Kaempferol treatment alleviated renal remodelling induced in rats by chronic hypertension. These mechanisms may be associated with the inhibition of ACE activity and suppression of the Ang II/AT1 receptor/NOX4/MMP-9 cell signalling pathway in renal tissue.</p>\u0000 </div>","PeriodicalId":15802,"journal":{"name":"Journal of Food Biochemistry","volume":"2024 1","pages":""},"PeriodicalIF":3.5,"publicationDate":"2024-07-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1155/2024/8810152","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"141968276","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"农林科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
