Research focus

  • To study how large histone variants called macroH2A1.1 and macroH2A1.2, splicing isoforms of macroH2A1, function as energy sensors and oncogenes in many cancer types and during induced pluripotent stem cells reprograming.
  • To understand the role of a rejuvenating factor, identified through parabiotic screening called Growth Differentiation Factor 11 (GDF11) in nutrient metabolism in mice.
  • Study of the variants of epigenetic enzyme SIRT6, which are involved in longer lifespan, as encountered in Ashkenazi Jews.

Main goals

  • Study the epigenetic macroH2A1 isoforms and DNA-damage components of endothelial cells repro­graming into induced pluripotent stem cells (iPSC).
  • Uncovering the side effects of the „youth factor“ GDF11 in obese mice and humans.
  • Dissect the role of longevity-associated mutants of SIRT6 in hepatic metabolism.
