Hepatoprotective effect of taurine and coenzyme Q10 and their combination against acrylamide-induced oxidative stress in rats

Purpose: To clarify the protective effects of Taurine (TA) and Coenzyme Q10 (CoQ10) for mitigation of acrylamide-induced oxidative damage. Method: Acrylamide (AA), TA and CoQ10 were administered orally to rats for 2 and 4 weeks. Sixty albino rats of either sex weighing 200 +/- 5 were randomly divided into five groups; control group, AA group, AA+ TA group, AA+ CoQ10 group and AA+ TA+ CoQ10 Group (15, 500 and 200 mg/kg/day dose, respectively). Hepatoprotection was assessed. The level of hepatic marker enzymes including serum lactate dehydrogenase (LDH), aspartate transaminase (AST) and alanine transaminase (ALT) were evaluated. The proinflammatory cytokines including serum levels of tumor necrosis factor-alpha (TNF-alpha), interleukin- 1 beta (IL-1 beta) and interleukin-6(IL-6) were assessed. The levels of reduced glutathione (GSH), malondialdehyde (MDA) and myeloperoxidase (MPO) in liver homogenate were also performed. Results: TA or CoQ10 significantly decreased (p < 0.05) the elevation of hepatic markers (LDH, AST and ALT) induced by AA in rats. Reduction of serum proinflammatory cytokines (TNF-alpha, IL-1 beta and IL-6) were also observed compared to AA group, and it was a time-effect relationship. Treatment with TA or CoQ10 also significantly reduced the oxidative stress induced by AA as shown by an increase in GSH level, and reduction of MDA level and MPO activities compared to rats treated with AA alone (p < 0.05). The hepatoprotective effect of both TA and CoQ10 combination was more efficient than the effect of either of them alone. Conclusion: The combination of TA and Co Q10 possesses a good potential to inhibit oxidative stress from liver and also exhibits anti-inflammatory activity. Thus, they have the potential to be used to mitigate AA-induced liver injury.
