    Synthetic lethality between the cohesin subunits STAG1 and STAG2 in diverse cancer contexts

    Petra van der Lelij et al.
    STAG1 has been identified as a hardwired genetic dependency of cancer cells harbouring mutations in the cohesin subunit and emerging major tumor suppressor STAG2 holds the promise for the development of selective therapeutics.

    A chloroplast retrograde signal, 3’-phosphoadenosine 5’-phosphate, acts as a secondary messenger in abscisic acid signaling in stomatal closure and germination

    Wannarat Pornsiriwong et al.
    Molecular signals from chloroplasts can synergistically interact with the plant hormone, abscisic acid (ABA), to regulate non-canonical signaling pathways mediating fundamental cellular processes including stomatal closure, seed dormancy and germination.

    High lumenal chloride in the lysosome is critical for lysosome function

    Kasturi Chakraborty et al.
    Lysosomes are highly enriched in chloride, which is essential for their degradative function.

    Novel mechanism of metabolic co-regulation coordinates the biosynthesis of secondary metabolites in Pseudomonas protegens

    Qing Yan et al.
    The production of two secondary metabolites is co-regulated in a bacterium via an intermediate in one pathway that is converted into signals to activate the second pathway.

    TRPV4 is the temperature-sensitive ion channel of human sperm

    Nadine Mundt et al.
    The molecular identity of the temperature-sensitive ion channel of human sperm that ensures depolarization is TRPV4.

    Role of framework mutations and antibody flexibility in the evolution of broadly neutralizing antibodies

    Victor Ovchinnikov et al.
    Computer simulations of the evolution of broadly neutralizing antibodies against HIV suggest that non-traditional pathways involving framework mutations which lead initially to increased antibody flexibility do occur, but can be avoided by appropriate vaccine design.
