Chromatin, Metabolism and Cell Fate Group

Our Research

In our scientific approach we combine biochemical techniques, cell culture and ultrasequencing of enriched chromatin fractions to address mechanistic and functional aspects of epigenetics. As model system for cell differentitiation we are currently using mouse embryonic stem cells, myoblasts and hematopoietic cells. Key findings are validated in vivo. For the study of cancer we combine established cell lines, de novo transformation of primary cultures and patient tissue.

Ongoing projects in the lab fall into four main themes:

  • The study of chromatin regulators affecting embryonic stem cell fate.
  • The link between metabolism and epigenetic regulation.
  • The regulation and molecular function of histone variants.
  • Chromatin as drug target in myeloid dysplastic syndrome and leukemia.

The longest ongoing line of our research focuses on the regulation and function of the histone variant macroH2A. Histones form the proteic core of the nucleosome, which is the modular building block of chromatin structure. MacroH2A is the only histone with a tripartite structure consisting of a N-terminal histone-fold, an intrinsically unstructured linker domain and a C-terminal macro domain. The incorporation of a macroH2A protein into the nucleosome places the macro domain in close proximity to the symmetrical axis and can be considered as the most extensive chromatin modification at the building block level.
From a large set of loss-of-function studies we could conclude that macroH2A is required for the establishment and maintenance of differentiated epigenomes. Although macroH2A is a well-established repressor, we now know that its pro-differetiation function in embryonic stem cells depends at least in part on a poorly understood function in transcriptional activation (Creppe, 2012, MCB). Want to know more? Please have a look at our recent reviews on macroH2A (Creppe, 2012; Posavec, 2013; Cantariño, 2013). In our current work we study the context-dependent function of the macro domain and the regulation of the locus-specific incorporation of macroH2A.
