    Mice deficient of Myc super-enhancer region reveal differential control mechanism between normal and pathological growth

    Kashyap Dave, Inderpreet Sur ... Jussi Taipale
    A tumor-specific regulatory region has been identified upstream of the Myc oncogene.

    Distinct roles of visual, parietal, and frontal motor cortices in memory-guided sensorimotor decisions

    Michael J Goard, Gerald N Pho ... Mriganka Sur
    Visual, parietal, and frontal motor cortices play distinct and necessary roles in mapping sensory features to future motor action.

    Label-free three-photon imaging of intact human cerebral organoids for tracking early events in brain development and deficits in Rett syndrome

    Murat Yildirim, Chloe Delepine ... Mriganka Sur
    Label-free three-photon imaging of whole, uncleared intact organoids generated from Rett syndrome patients show shorter migration distances and slower migration speeds of mutant radially migrating neurons with more tortuous trajectories.

    Tradeoffs explain scaling, sex differences, and seasonal oscillations in the remarkable weapons of snapping shrimp (Alpheus spp.)

    Jason P Dinh, SN Patek
    Observational field analyses demonstrate that within a species, variation in animal weapon size corresponds to individual differences in the costs and benefits of weaponry.

    SDR enzymes oxidize specific lipidic alkynylcarbinols into cytotoxic protein-reactive species

    Pascal Demange, Etienne Joly ... Sébastien Britton
    Deciphering the mechanism of action of a large family of natural and synthetic cytotoxic lipids bioactivated by enantiospecific oxidation into protein-reactive species inspires the development of enzyme-specific prodrugs.

    Inositol polyphosphate multikinase physically binds to the SWI/SNF complex and modulates BRG1 occupancy in mouse embryonic stem cells

    Jiyoon Beon, Sungwook Han ... Daeyoup Lee
    Inositol polyphosphate multikinase physically binds to the core subunits of SWI/SNF complex and plays an important role in regulating BRG1 occupancy and BRG-mediated chromatin accessibility in mouse embryonic stem cells.

    A qnr-plasmid allows aminoglycosides to induce SOS in Escherichia coli

    Anamaria Babosan, David Skurnik ... Thomas Guillard
    A mechanism whereby aminoglycosides-mediated SOS induction in Escherichia coli also promote high-level fluoroquinolone resistance.

    SWI/SNF senses carbon starvation with a pH-sensitive low-complexity sequence

    J Ignacio Gutierrez, Gregory P Brittingham ... Liam J Holt
    A combination of single-cell analysis, genomics, and simulations shows that a glutamine-rich low-complexity sequence in the SWI/SNF chromatin remodeling complex senses transient intracellular acidification as a signal for cells to switch their global transcriptional program.

    In vivo analysis reveals that ATP-hydrolysis couples remodeling to SWI/SNF release from chromatin

    Ben C Tilly, Gillian E Chalkley ... C Peter Verrijzer
    Visualization of BRM remodelers engaging their endogenous genomic targets revealed highly transient and dynamic interactions with chromatin, which are fueled by ATP-hydrolysis.
