(Submitter supplied) Dynamic interactions of nuclear lamins with chromatin through so-called lamin-associated domains (LADs) contribute to spatial arrangements of the genome. Here, we provide evidence for pre-patterning of differentiation-driven formation of lamin A/C LADs by domains of histone H2B modified by the nutrient sensor O-linked N-acetylglucosamine (H2BGlcNAc), which we term GADs. We demonstrate a two-step process of lamin A/C LAD formation during in vitro adipogenesis, involving (i) a spreading of lamin A/C-chromatin interactions during the transition from progenitor cell proliferation to cell cycle arrest, and (ii) a genome-scale redistribution these interactions through a process of LAD ‘exchange’ within hours of adipogenic induction. more...
