Abstract
Polystyrene microplastics (PS-MPs) are raising global concerns as they have tendency to induce adverse effects on organisms. Herbacetin (HBN) is a natural flavone that shows diverse biological activities. Therefore, the current study was designed to evaluate the curative role of HBN against PS-MPs provoked hepatic damage. Forty-eight rats were divided into 4 groups, control, PS-MPs-intoxicated (0.01 mg/kg), PS-MPs + HBN co-treated (0.01 mg/kg + 40 mg/kg) and HBN only treated (40 mg/kg) group. The experiment was conducted for 30 days. PS-MPs administration reduced the expressions of Nrf-2 as well as anti-oxidants genes and increased Keap-1 expression. It also lessened the activities of superoxide dismutase (SOD), glutathione reductase (GSR), catalase (CAT), glutathione peroxidase (GPx), glutathione-S-transferase (GST) and heme oxygenase-1 (HO-1) and glutathione (GSH) level, while elevating the levels of MDA and ROS. Additionally, PS-MPs exposure augmented the levels of alkaline phosphatase (ALP), aspartate aminotransferase (AST) and alanine transaminase (ALT). Furthermore, there was an upsurge in the levels of inflammatory indices in PS-MPs treated group. PS-MPs also upregulated Caspase-3 and Bax expression whereas, decreased Bcl-2 expression. Nevertheless, HBN treatment recovered all the impairments due to its anti-apoptotic, anti-oxidant and anti-inflammatory and hepatoprotective nature. Therefore, it is deduced that HBN could be used as a potential therapeutic agent to counter PS-MPs induced hepatic toxicity.
