Metabolomics of Hepatocarcinogenesis Induced by Peroxisome Proliferators

Incipient metabolomics technology possesses the power of biomarker identification through monitoring the global changes of biofluid/tissue metabolomes, and carcinogen sensitive/resistant mouse models originated from genetic engineering provides a unique platform for studying pathways of carcinogenesis. In this study, the researchers combine the LC-MS-based metabolomics technology and genetically-modified mouse models to investigate the mechanism of species-specific hepatocarcinogenesis induced by peroxisome proliferators through comparing the metabolomic changes in wild-type, mPparĀ·-null and humanized PPARĪ± mice following short-term and long-term fenofibrate treatments. Potential discovery of biomarkers for peroxisome proliferation and hepatocellular proliferation will have important applications in disease diagnosis and therapeutics, and in cancer risk assessment.
