Research Abstract |
We found some histone modifications that change its localization and amount between embryonic hepatic stem cells and adult hepatocytes. We identified their target genes at genomic level, demonstrating vast majority of the targets of a repressive histone mark, H3K27me3, are mutually exclusive. An integrated analysis revealed that some functional genes involved in metabolisms were repressed by H3K27me3 and that some early development-related and cell cycle-promoting genes were associated with distinct transcription activating pattern of the histone marks in the hepatic stem cells.
