The organ toxicity of doxorubicin (DOX), an anthracycline antineoplastic agent, narrows the therapeutic window despite its clinical usefulness. In the present study, we determined whether taurine protected against DOX-induced hepatic injury, and explored the molecular mechanisms underlying the suppressive effects of taurine in terms of alterations in oxidative stress and apoptotic responses. DOX-induced body weight loss was completely suppressed by taurine treatment. Elevations in the serum activity levels of lactate dehydrogenase, aspartate aminotransferase, and alanine aminotransferase by DOX were also dose-dependently attenuated by a concurrent treatment with taurine. Superoxide dismutase activity and reduced glutathione content in the liver were decreased following the administration of DOX, whereas these changes were suppressed when 10 mg/kg taurine was given in combination with DOX. Taurine attenuated the increased expression of mRNAs for Fas and Bax after DOX exposure. Furthermore, the formation of cleaved caspase-3 protein in the group given DOX with taurine was lower than that in the group treated with DOX alone. Our results suggest that taurine can protect against DOX-induced acute hepatic damage, the underlying mechanism of which is attributable to the suppression of oxidative stress and apoptotic responses.
