Pu-erh black tea extract supplementation attenuates the oxidative DNA damage and oxidative stress in Sprague-Dawley rats with renal dysfunction induced by subchronic 3-methyl-2-quinoxalin benzenevinylketo-1,4-dioxide exposure

► Quinocetone, a new feeding antibacterial agent, shows potential nephrotoxicity in vivo. ► The nephrotoxicity induced by Quinocetone was associated with DNA damage and oxidative stress. ► The nephrotoxicity induced by Quinocetone could be attenuated by PBTE supplementation.
