Outline of Final Research Achievements

Liver cancers, including hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma, generally arise in liver chronically inflamed due to various diseases such as hepatitis virus infection and steatohepatitis. Chronic inflammation triggers the aberrant expression of a DNA mutator enzyme, activation-induced cytidine deaminase (AID), and contributes to tumorigenesis through the accumulation of genetic aberrations. To gain further insight into the inflammation-mediated genotoxic events required for carcinogenesis, we examined the role of chronic inflammation in the emergence of genetic aberrations in the liver with constitutive AID expression. We found that inflammation-mediated transcriptional upregulation of target genes, including putative tumor suppressor genes, enhances the opportunity for inflamed cells to acquire somatic mutations and contributes to the acceleration of tumorigenesis in the inflamed liver tissues.
