    Controlling gene activation by enhancers through a drug-inducible topological insulator

    Taro Tsujimura, Osamu Takase ... Keiichi Hishikawa
    A novel synthetic DNA cassette of CTCF-binding sites combined with the drug-controllable induction system of heterochromatin enabled switchable blocking of chromatin conformation and gene-enhancer interaction.

    Mitochondrial redox adaptations enable alternative aspartate synthesis in SDH-deficient cells

    Madeleine L Hart, Evan Quon ... Lucas B Sullivan
    SDH-null cancer cells decrease mitochondrial complex I to drive rewired aspartate synthesis through reductive carboxylation and pyruvate carboxylase, supporting cell proliferation and tumor growth.

    Deletion of Stk11 and Fos in mouse BLA projection neurons alters intrinsic excitability and impairs formation of long-term aversive memory

    David Levitan, Chenghao Liu ... Sacha B Nelson
    Stk11 and Fos expression plays an important role in CTA long-term memory formation by modulating the intrinsic excitability of BLApn.

    Cystic proliferation of germline stem cells is necessary to reproductive success and normal mating behavior in medaka

    Luisa F Arias Padilla, Diana C Castañeda-Cortés ... Juan I Fernandino
    In medaka fish, the reduction of cystic proliferation of germ stem cells declines gametogenesis, reproduction success, and male sexual behavior, with a decrease of mating vigor.

    Multi-targeted therapy resistance via drug-induced secretome fucosylation

    Mark Borris D Aldonza, Junghwa Cha ... Yoosik Kim
    Targeted therapies induce an aberrant fucosylation of complex tumor secretomes stimulating the expansion of minority drug-resistant clones and promoting therapy 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.

    Transcription-coupled genetic instability marks acute lymphoblastic leukemia structural variation hotspots

    Merja Heinäniemi, Tapio Vuorenmaa ... Olli Lohi
    Convergent transcription and stalling of transcription are enriched at DNA breakpoints found in acute lymphoblastic leukemia and associate with DNA structures and sequences that mediate genetic instability.

    Coopted temporal patterning governs cellular hierarchy, heterogeneity and metabolism in Drosophila neuroblast tumors

    Sara Genovese, Raphaël Clément ... Cédric Maurange
    About twenty temporal patterning genes are identified that drive an irreversible differentiation trajectory governing the heterogeneity and proliferative properties of cells in neural tumors with an early developmental origin.

    Modelling the impact of decidual senescence on embryo implantation in human endometrial assembloids

    Thomas M Rawlings, Komal Makwana ... Emma S Lucas
    The study of embryo-endometrial interactions in assembloid co-cultures identifies novel mechanisms of reproductive failure.

    Homeostatic plasticity fails at the intersection of autism-gene mutations and a novel class of common genetic modifiers

    Özgür Genç, Joon-Yong An ... Graeme W Davis
    Forward genetic screens define a novel genetic landscape by which diverse, unrelated autism risk genes may converge to commonly affect the robustness of synaptic transmission.
