    Structural plasticity of actin-spectrin membrane skeleton and functional role of actin and spectrin in axon degeneration

    Guiping Wang et al.
    Neurotrophin deprivation leads to rapid caspase-independent disassembly of the actin-spectrin-based membrane skeleton and spectrin-dependent retrograde signaling in axon degeneration.

    An atomic-resolution view of neofunctionalization in the evolution of apicomplexan lactate dehydrogenases

    Jeffrey I Boucher et al.
    The convergent evolution of unusually strict substrate specificity in apicomplexan LDHs arose by classic neofunctionalization of a duplicated MDH gene via few mutations of large effect.

    Delayed antibiotic exposure induces population collapse in enterococcal communities with drug-resistant subpopulations

    Kelsey M Hallinen et al.
    Collapse of bacterial communities containing antibiotic-resistant and susceptible cells can be driven by increased population size or delayed drug exposure.

    A novel checkpoint pathway controls actomyosin ring constriction trigger in fission yeast

    Tomás Edreira et al.
    In fission yeast cell wall stress triggers a cytokinesis blockage specifically in the onset of actomyosin ring constriction.

    Golgi self-correction generates bioequivalent glycans to preserve cellular homeostasis

    Haik Mkhikian et al.
    Structurally dissimilar N-glycans can be functionally equivalent, and are produced via a self-correcting feature of the Golgi.

    Metabolic flexibility via mitochondrial BCAA carrier SLC25A44 is required for optimal fever

    Takeshi Yoneshiro et al.
    Genetic and cellular studies in rodents found branched-chain amino acids are critical nutrients that are transported and oxidized in the mitochondria through their carrier MBC for optimal febrile responses.

    Allosteric communication in class A β-lactamases occurs via cooperative coupling of loop dynamics

    Ioannis Galdadas et al.
    A combination of equilibrium and nonequilibrium molecular dynamics simulations is an effective tool to study allosteric communications in ultrafast enzymes that show little or no conformational changes.

    Collateral sensitivity associated with antibiotic resistance plasmids

    Cristina Herencias et al.
    Acquisition of antibiotic resistance plasmids induces collateral sensitivity to clinically relevant antibiotics in Escherichia coli, paving the way for targeted 'anti-plasmid' therapies able to preferentially eliminate plasmid-carrying bacteria.

    Flotillin-mediated membrane fluidity controls peptidoglycan synthesis and MreB movement

    Aleksandra Zielińska et al.
    Correct cell wall synthesis in bacteria depends on flotillin-mediated membrane fluidity.

    A positive feedback loop between Myc and aerobic glycolysis sustains tumor growth in a Drosophila tumor model

    Kenneth Kin Lam Wong et al.
    Specific molecular links that orchestrate growth signals and metabolic reprogramming to achieve tumorigenesis are identified as potential metabolic vulnerabilities in cancer treatment.
