Objective: Hepatotoxicity is one of the major side effects of methotrexate and limits its use. In this study, we investigated the hepatoprotective effect of silibinin and the role of oxidative stress markers and cytokines on high-dose methotrexate-induced hepatotoxicity in rats.
Materials And Methods: In this study, rats were randomly divided into 5 groups (n=7). Methotrexate (20 mg/kg, intraperitoneally) was administered on the first day in all groups except control. Silibinin was injected for 5 days to methotrexate-silibinin25, methotrexate-silibinin50, and methotrexate-silibinin100 groups at a dose of 25, 50, and 100 mg/kg/day, respectively. On the sixth day, blood and liver samples were obtained and rats were sacrificed. Serum total antioxidant capacity, total oxidant status, total thiol, native thiol, alanine aminotransferase, aspartate transaminase, bilirubin, albumin, tumor necrosis factor-alpha, and interleukin-10 levels were measured. In addition, a histopathological evaluation of liver tissues was performed.
Results: Methotrexate reduced total antioxidant capacity and increased disulfide/total thiol ratio. Histopathologic examination revealed that methotrexate increased hepatic damage and 50 mg/kg/dose of silibinin prevented inflammatory cell infiltration in particular.
Conclusion: Our results suggest that silibinin (50 mg/kg/day) may reduce the hepatic damage in methotrexate-induced hepatotoxicity in rats by increasing antioxidant capacity.

Ethnopharmacological Relevance: Mangifera indica (family Anacardiaceae), often acknowledged as mango and renowned for being a plant of diverse ethnopharmacological background since ancient times, harbors the polyphenolic bioactive constituent, mangiferin (MNG). MNG is a major phytochemical of Mangifera indica and other plants with a wide range of reported pharmacological activities, including antioxidant, anti-inflammatory, neuroprotective and hepatoprotective effects. MNG has also been utilized in traditional medicine; it is reportedly a major bioactive element in over 40 polyherbal products in traditional Chinese medicine (TCM), and two prominent anti-inflammatory, immunomodulatory and antiviral Cuban formulations.

Hepatotoxicity is an under-recognized and potentially fatal side effect of high-dose methotrexate (HDMTX) chemotherapy, and this risk is compounded in children with metabolic dysfunction-associated steatotic liver disease and/or metabolic-associated steatohepatitis. We present the case of a 12-year-old obese, Hispanic male with elevated hepatic transaminases of unknown etiology at initiation of high-risk B-cell acute lymphoblastic leukemia chemotherapy. He developed acute kidney injury within 24 hours of receiving intravenous HDMTX which progressed to acute hepatic failure.

Methotrexate (MTX), a widely used chemotherapeutic agent, often induces hepatotoxicity, limiting its clinical utility. Cannabidiol (CBD), derived from hemp, possesses antioxidant, anti-inflammatory, and antiapoptotic properties. This study aims to investigate CBD's protective effects against MTX-induced liver injury and elucidate the underlying mechanisms.

Methotrexate (MTX), an anti-metabolite agent, is a widely used chemotherapeutic anticancer drug, but its hepatotoxicity severely limits its clinical application. Nevertheless, the precise mechanisms of MTX-caused liver damage are extremely intricate and still need to be fully clarified. In the current study, we investigated the role of the STING-ERS-ferroptosis axis in MTX-triggered hepatic toxicity in vivo and in vitro models.
