Abstract:

Methotrexate (MTX) is an efficient chemotherapeutic agent for treating various malignancies and autoimmune diseases. However, the long-term use of MTX can result in hepatotoxicity and this limits its use. Galangin (Gal) is a potent flavonoid with various biological activities; however, its protective effect against MTX hepatotoxicity has not been previously investigated. This study evaluated the hepatoprotective of Gal against MTX-induced liver injury. Rats received Gal for 10 days and a single dose of MTX (20 mg/kg) at day 7. The administration of MTX induced liver damage reflected by increased serum biomarkers of liver function and histopathological manifestations. MTX increased hepatic reactive oxygen species (ROS), nitric oxide (NO), malondialdehyde (MDA), and pro-inflammatory cytokines (TNF-α, IL-1β, and IL-6), and diminished GSH and antioxidant enzymes. Gal relieved liver injury, ameliorated liver function, oxidative stress, and inflammation markers, and increased antioxidants in MTX-treated rats. In addition, Gal decreased the expression of inflammationand apoptosis markers in MTX-treated rats. In conclusion, Gal possesses a hepatoprotective effect mediated by attenuating oxidative damage, inflammation, and apoptosis in rats.
