The aim of this study was to investigate the hepatoprotective effects of kaempferol, an antioxidant flavonoid found in various edible vegetables, and its underlying mechanism in male Sprague-Dawley rats with carbon tetrachloride (CCl4)-induced acute liver damage. Oral administration of kaempferol at doses of 5 and 10 mg\/kg body weight resulted in the amelioration of CCl4-induced abnormalities in hepatic histology and serum parameters. Additionally, kaempferol decreased the levels of pro-inflammatory mediators, TNF-\u03b1 and IL-1\u03b2, as well as COX-2 and iNOS. Furthermore, kaempferol suppressed nuclear factor-kappa B (NF-\u03baB) p65 activation, as well as the phosphorylation of Akt and mitogen-activated protein kinase members (MAPKs), including extracellular signal-regulated kinase, c-Jun NH2-terminal kinase, and p38 in CCl4-intoxicated rats. In addition, kaempferol improved the imbalanced oxidative status, as evidenced by the reduction in reactive oxygen species levels and lipid peroxidation, along with increased glutathione content in the CCl4-treated rat liver. Administering kaempferol also enhanced the activation of nuclear factor-E2-related factor (Nrf2) and heme oxygenase-1 protein, as well as the phosphorylation of AMP-activated protein kinase (AMPK). Overall, these findings suggest that kaempferol exhibits antioxidative, anti-inflammatory, and hepatoprotective effects through inhibiting the MAPK\/NF-\u03baB signaling pathway and activating the AMPK\/Nrf2 signaling pathway in CCl4-intoxicated rats.<\/jats:p>","DOI":"10.3390\/ijms24086900","type":"journal-article","created":{"date-parts":[[2023,4,10]],"date-time":"2023-04-10T03:26:06Z","timestamp":1681097166000},"page":"6900","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":42,"title":["Kaempferol Suppresses Carbon Tetrachloride-Induced Liver Damage in Rats via the MAPKs\/NF-\u03baB and AMPK\/Nrf2 Signaling Pathways"],"prefix":"10.3390","volume":"24","author":[{"given":"Changyong","family":"Lee","sequence":"first","affiliation":[{"name":"College of Pharmacy, Pusan National University, Busan 46241, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6449-0761","authenticated-orcid":false,"given":"Sik","family":"Yoon","sequence":"additional","affiliation":[{"name":"Department of Anatomy, College of Medicine, Pusan National University, Yangsan 50612, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jeon-Ok","family":"Moon","sequence":"additional","affiliation":[{"name":"College of Pharmacy, Pusan National University, Busan 46241, Republic of Korea"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2023,4,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Vona, R., Pallotta, L., Cappelletti, M., Severi, C., and Matarrese, P.
