    Evidence for DNA-mediated nuclear compartmentalization distinct from phase separation

    David Trombley McSwiggen et al.
    Transient DNA interactions by DNA-binding proteins are utilized by herpes simple virus as an alternative route to generate membraneless compartments in the nucleus without invoking phase separation.

    A 3D culture model of innervated human skeletal muscle enables studies of the adult neuromuscular junction

    Mohsen Afshar Bakooshli et al.
    Human skeletal muscle progenitors and motor neurons self-organize in three-dimensional co-culture to form functional neuromuscular junctions that developmentally mature from the embryonic to the adult state.

    The Hox transcription factor Ubx stabilizes lineage commitment by suppressing cellular plasticity in Drosophila

    Katrin Domsch et al.
    The Hox transcription factor Ultrabithorax (Ubx) represses alternative gene programs during lineage development by lineage-specific Polycomb protein complex retention at Ubx-targeted chromatin sites.

    Quantification of microenvironmental metabolites in murine cancers reveals determinants of tumor nutrient availability

    Mark R Sullivan et al.
    The nutrients available in some tumors and the factors that influence tumor nutrient availability are characterized, which provides insight into the metabolic constraints of the tumor microenvironment.
