    摘要: The present invention provides various biomarkers for hepatotoxicity and various methods of using the biomarkers Some of the biomarkers within the scope of this invention are cholate, glycochenodeoxycholate, glycocholate, taurine, 3-hyroxy-2-ethylpropionate, 4-imidazoleacetate, tyramine, anthranilate, 2′-deoxycytidine, N-acetyl aspartate (NAA), beta-hydroxy-hexanoate, and sarcosine (N-methylglycine) The methods of using the biomarkers include exposing a first hepatocyte culture to a test agent and comparing the levels of the one or more biomarkers obtained in the first hepatocyte culture to the levels of the one or more biomarkers obtained in a second hepatocyte culture without the test agent, where differential levels of the one or more biomarkers in the first hepatocyte culture as compared to the levels in the second hepatocyte culture is indicative of the test agent being a hepatotoxicant.
