  1. Cheutin T, Cavalli G. Loss of PRC1 induces higher-order opening of Hox loci independently of transcription during Drosophila embryogenesis. Nat Commun. 2018;9:3898 pubmed publisher
    ..Our data suggest that PRC1 maintains gene silencing by folding chromatin domains and impose architectural layer to gene regulation. ..

    ..Preventing loop formation without removal of polycomb components also decreases silencing efficiency, suggesting that chromatin architecture can play instructive roles in gene regulation during development. VIDEO ABSTRACT. ..
  3. Ciabrelli F, Cavalli G. Chromatin-driven behavior of topologically associating domains. J Mol Biol. 2015;427:608-25 pubmed publisher
    ..In this review, we will describe the main three-dimensional features of each chromatin type and finally their relationships with TAD organization and epigenetic memory. ..

    ..These data suggest that cooperative rather than hierarchical interactions among low-affinity sequences, DNA-binding factors, and the Polycomb machinery are giving rise to specific and strongly conserved 3D structures in Drosophila. ..
