Changes in the pattern of gene expression play an important role in allowing
cancer cells to acquire their hallmark characteristics, while genomic instability
enables cells to acquire genetic alterations that promote oncogenesis. Chromatin
plays central roles in both transcriptional regulation and the maintenance of
genomic stability. Studies by cancer genome consortiums have identified frequent
mutations in genes encoding chromatin regulatory factors and histone proteins in
human cancer, implicating them as major mediators in the pathogenesis of both
hematological malignancies and solid tumors. Here, we review recent advances in
our understanding of the role of chromatin in cancer, focusing on transcriptional
regulatory complexes, enhancer-associated factors, histone point mutations, and
alterations in heterochromatin-interacting factors.
