THE ROLE OF MACRO DOMAIN-MEDIATED REGULATION OF CHROMATIN STRUCTURE AND FUNCTION DURING CANCER AND SENESCENCE

Macro domains are found in several histone variants, chromatin remodelers, and other transcriptional coregulators (e.g. macroH2A, PARP14, CHD1L) with roles in cancer progression, senescence, innate immune responses, and viral pathogenesis. These protein modules function, in part, as ligand binding domains for NAD+-derived poly(ADP-ribose), ADP-ribose, and O-acetyl-ADP-ribose. The ability of macro domains to bind these ligands links the function of macro domain-containing proteins (MDCPs) to NAD+-dependent signaling events catalyzed by NAD+-utilizing enzymes such as PARP-1, PARG and SIRT1. Our laboratory employs a variety of cell-based, genomic and biochemical techniques to explore the role of macro domains, their ligands and the NAD+-utilizing enzymes that produce them in transcriptional regulation.

The histone variant macroH2A1 is an MDCP of particular interest to our group. MacroH2A1 incorporates into nucleosomes found in large chromatin domains that occupy a quarter of the genome in human cells. MacroH2A1 exists as one of two splice variants, macroH2A1.1 which can bind to NAD+-derived ligands, and macroH2A1.2 which cannot associate with these small molecules. Interestingly, while both macroH2A1 variants are present in normal adult cells, macroH2A1.1 splicing is decreased in a variety of human cancers including endometrial, lung, testicular, colon, and bladder cancer. Additionally, macroH2A1.1 can trigger an innate tumor suppressive pathway called oncogene-induced senescence. We are currently exploring the mechanisms that regulate macroH2A1 splicing, the specific roles of each macroH2A variant in transcriptional regulation, and how these processes are perturbed during oncogenesis.
