Hesperidin, a citrus bioflavonoid, alleviates trichloroethylene-induced oxidative stress in Drosophila melanogaster

Publication date: October 2017 Source:Environmental Toxicology and Pharmacology, Volume 55 Author(s): Amos Olalekan Abolaji, Oluwatoyin Victoria Babalola, Abimbola Kehinde Adegoke, Ebenezer Olatunde Farombi Trichloroethylene (TCE) is a chlorinated organic pollutant of groundwater with diverse toxic effects in animals and humans. Here, we investigated the ameliorative role of hesperidin, a citrus bioflavonoid on TCE-induced toxicity in Drosophila melanogaster. Four groups of D. melanogaster (50 flies/vial, with 5 vials/group) were exposed to ethanol (2.5%, control), HSP (400mg/10g diet), TCE (10μM/10g diet) and TCE (10μM/10g diet)+HSP (400mg/10g diet) respectively in the diet for 5days. Then, selected oxidative stress and antioxidant markers were evaluated. The results showed that TCE significantly increased the level of reactive oxygen species (ROS) and inhibited catalase, glutathione S-transferase and acetylcholinesterase (AChE) activities with concurrent depletion of total thiol level. However, co-administration of TCE and hesperidin mitigated TCE-induced depletion of antioxidants, and restored ROS level and AChE activity in the flies (p<0.05). Overall, hesperidin offered protective potency on TCE-induced oxidative stress in the flies via anti-oxidative mechanism. Graphical abstract
