Biocomponents from Opuntia robusta and Opuntia streptacantha fruits protect against diclofenac-induced acute liver damage in vivo and in vitro
Journal of Functional Foods(2022)
Abstract
This study aimed to investigate whether Opuntia spp-extracts protect against diclofenac (DF)-induced hepatotoxicity. Rats were pretreated with Opuntia extracts, betanin (Bet) and N-acetylcysteine (NAC) followed by a single challenge of diclofenac. Liver tissue was collected for biochemical and histological analysis. Primary rat hepatocytes were treated with diclofenac (400 mu mol/L) with and without pretreatment with Opuntia extract. Apoptosis was measured by caspase-3 activity and necrosis by Sytox green staining. RNA was isolated, and realtime qPCR was performed to assess mRNA levels of stress and apoptosis-related genes MnSOD (SOD2), GADD45B and P53. ROS production was measured using the fluorescent MitoSOX assay. Results demonstrated that Opuntia spp-extracts protect against DF-induced liver toxicity via reducing oxidative stress and the inhibition of P53.
