Phenotypic changes in injured livers involve complex network of genes whose interplays may lead to fibrosis and cirrhosis, a major risk of hepatocellular carcinoma. Gene expression profiles in fibrotic livers were analyzed by using cDNA microarray, hierarchical clustering and gene ontology. Analyses of a major cluster of upregulated genes in cirrhosis identified a new set of genes involved in DNA repair and damage. The upregulation of DNA repair genes was confirmed by real-time quantitative polymerase chain reaction and associated with necroinflammatory activity (P < 0.001). Increased DNA repair activity in cirrhosis with inflammatory activity may reflect increased DNA damages as a consequence of chronic liver injury.
