In the current report, we examined the potential beneficial role of soursop fruit extract (SSFE) on liver injury induced by a single paracetamol (APAP) overdose (2000 mg/kg). Thirty-five Wistar albino rats were randomly divided into five groups as follows: control, SSFE, APAP, SSFE+APAP, and silymarin (SIL)+APAP. APAP intoxication was found to elevate alanine aminotransferase, aspartate aminotransferase, alkaline phosphatase, and total bilirubin levels. Moreover, it increased the levels of malondialdehyde, nitrites, and nitrates and depleted glutathione, superoxide dismutase, catalase, glutathione reductase, and glutathione peroxidase. APAP intoxication inactivated the nuclear factor erythroid 2-related factor 2 (Nrf2) defense pathway and upregulated the expression of heme oxygenase-1 (HO-1). APAP administration enhanced the activation of nuclear factor-kappa B (NF-κB), the elevation of tumor necrosis factor-alpha and interleukin 1-beta levels, and the upregulation of inducible nitric oxide synthase mRNA expression. In addition, APAP activated the overexpression of Bax protein, increased release of cytochrome c, and the downregulation of Bcl-2 protein. Finally, APAP-induced overexpression of transforming growth factor-beta (TGF-β) further suggested enhanced liver damage. On the other hand, SSFE pretreatment attenuated these biochemical, molecular, and histopathological alterations in the liver, which might be partially due to the regulation of hepatic Nrf2/HO-1 and downregulation of NF-κB and TGF-β.
