The present study is designed to search for the serum cytokine biomarker for liver injury induced by Dioscorea bulbifera L., which is a traditionally used herbal medicine in China. Mice were orally given various doses of ethyl acetate extract (EF) isolated from D. bulbifera for 12 days. The activity of serum alanine/aspartate transaminases (ALT/AST) was increased in EF (400 mg/kg)-treated mice. Histological assessment further confirmed EF (400 mg/kg)-induced liver injury. Results of a cytokine-antibody array demonstrated that there were 10 cytokines up-regulated and 1 cytokine down-regulated in EF (400 mg/kg)-treated mice. Enzyme-linked immunosorbent assay (ELISA) further confirmed the increased level of CD30 ligand (CD30L) and decreased level of interlukin-3 (IL-3) in EF-treated mice. In conclusion, our results demonstrate that the altered expression of CD30L and IL-3 may be potential biomarkers for hepatotoxicity induced by D. bulbifera.
