Hdac3 is essential for the maintenance of chromatin structure and genome stability

Deletion of Hdac3 impaired DNA repair and greatly reduced chromatin compaction and heterochromatin content. Liver-specific deletion of Hdac3 culminated in hepatocellular carcinoma. The loss of genomic stability and the impaired response to DNA damage suggested that a high mutation rate stimulated the development of HCC. To begin to assess what pathways were involved in the formation of HCC, we performed gene expression analysis using cDNA microarrys.
