| Outline of Final Research Achievements |
In the present study, QSTAR Elite LC-MS/MS and ingenuity Pathway Analysis were employed to search the potential biomarker candidates of non-alcoholic steatohepatitis (NASH)-associated liver cancer, and to discover the molecular mechanisms in NASH hepatocarcinogenesis. The experiments were performed with metabolic syndrome model Tsumura, Suzuki, Obese Diabetes (TSOD), and Tsumura, Suzuki, Non Obesity (TSNO) mice used as control. The incidences and multiplicities of putative preneoplastic foci and liver tumors were significantly increased in TSOD as compared with TSNO mice. Glutathione S-transferase pi 1 and acyl-CoA oxidase 1 were significantly elevated in TSOD mice. Activation of insulin, leptin, β-catenin pathways as well as transcription factor 7-like 2 are suggested to be implicated in NASH hepatocarcinogenesis.
