Chrysin mitigates diclofenac-induced hepatotoxicity by modulating oxidative stress, apoptosis, autophagy and endoplasmic reticulum stress in rats

Background Diclofenac (DF) is a non-steroidal anti-inflammatory drug (NSAID) generally prescribed for the treatment of pain. In spite of the widespread use of DF, hepatotoxicity has been reported after its administration. The current study discloses new evidence as regards of the curative effects of chrysin (CHR) on DF-induced hepatotoxicity by regulating oxidative stress, apoptosis, autophagy, and endoplasmic reticulum (ER) stress. Methods The animals were separated into five different groups. Group-I was in control. Group-II received CHR-only (50 mg/kg bw, p.o.) on all 5 days. Group-III received DF-only (50 mg/kg bw, i.p.) on 4th and 5th day. Group-IV received DF (50 mg/kg bw) + CHR (25 mg/kg, bw) and group-V received DF (50 mg/kg, bw) + CHR (50 mg/kg, bw) for 5 days. Results DF injection was associated with increased MDA while reduced GSH level, activities of superoxide dismutase, glutathione peroxidase, and catalase and mRNA levels of HO-1 and Nrf2 in the liver. DF injection caused apoptosis and autophagy in the liver by up-regulating caspase-3, Bax, LC3A, and LC3B levels and down-regulating Bcl-2. DF also caused ER stress by increasing mRNA transcript levels of ATF-6, IRE1, PERK, and GRP78. Additionally, it was observed that DF administration up-regulated MMP2 and MMP9. However, treatment with CHR at a dose of 25 and 50 mg/kg considerably ameliorated oxidative stress, apoptosis, autophagy, and ER stress in liver tissue. Conclusion Overall, the data of this study indicate that liver damage associated with DF toxicity could be ameliorated by CHR administration.
