The DNA damage, most notably DNA double-strand breaks, poses a serious threat to the stability of mammalian genome. Maintenance of genomic integrity is largely dependent on an efficient, accurate, and timely DNA damage response in the context of chromatin. Consequently, dysregulation of the DNA damage response machinery is fundamentally linked to the genomic instability and a likely predisposition to cancer. In turn, aberrant activation of DNA damage response pathways in human cancers enables tumor cells to survive DNA damages, thus, leading to the development of resistance of tumor cells to DNA damaging radio- and chemotherapies. A substantial body of experimental evidence has established that ATP-dependent chromatin remodeling and histone modifications play a central role in the DNA damage response. As a component of the nucleosome remodeling and histone deacetylase (NuRD) complex that couples both ATP-dependent chromatin remodeling and histone deacetylase activities, the metastasis-associated protein (MTA) family proteins have been recently shown to participate in the DNA damage response beyond its well-established roles in gene transcription. In this thematic review, we will focus on our current understandings of the role of the MTA family proteins in the DNA damage response and their potential implications in DNA damaging anticancer therapy.
