    Cellular hallmarks reveal restricted aerobic metabolism at thermal limits

    Aitana Neves et al.
    Cellular hallmarks of thermal limits are evolutionarily conserved in nematodes, and changes in surface to volume ratio reflect restricted aerobic metabolism at these limits.

    Metabolic reprogramming during neuronal differentiation from aerobic glycolysis to neuronal oxidative phosphorylation

    Xinde Zheng et al.
    The shutoff of aerobic glycolysis in neuronal differentiation is essential for neuronal survival.

    Drosophila macrophages switch to aerobic glycolysis to mount effective antibacterial defense

    Gabriela Krejčová et al.
    Activated Drosophila macrophages undergo transient metabolic remodeling towards Hypoxia inducible factor 1 α-driven aerobic glycolysis, a program that induces systemic metabolic changes and is crucial for resistance to infection.

    Rhodoquinone biosynthesis in C. elegans requires precursors generated by the kynurenine pathway

    Samantha Del Borrello et al.
    Parasitic helminths infect over a billion humans and use unusual anaerobic metabolism that needs a rare electron carrier, Rhodoquinone (RQ), whose synthesis requires the kynurenine pathway of tryptophan degradation.

    Glycolysis and glutaminolysis cooperatively control T cell function by limiting metabolite supply to N-glycosylation

    Lindsey Araujo et al.
    Metabolic switches between oxidative phosphorylation and aerobic glycolysis plus glutaminolysis direct T cell function by altering the flux of glucose and glutamine to N-glycosylation.

    Glycolytic reliance promotes anabolism in photoreceptors

    Yashodhan Chinchore et al.
    Aerobic glycolysis in rod photoreceptors of adult mice is regulated by allostery and FGF signaling and is required for maintaining outer segments.

    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.

    Underground isoleucine biosynthesis pathways in E. coli

    Charles AR Cotton et al.
    Upon deletion of threonine deaminases, biosynthesis of isoleucine is rescued by two promiscuous reactions, one emerges under aerobic conditions and the other is naturally active under anaerobic conditions.

    Reduced metabolism supports hypoxic flight in the high-flying bar-headed goose (Anser indicus)

    Jessica U Meir et al.
    Measurements of bar-headed geese flying in a wind tunnel in hypoxia reveal that these birds sustain aerobic flight at high altitude via a reduction in metabolism.

    Insight into the evolution of microbial metabolism from the deep-branching bacterium, Thermovibrio ammonificans

    Donato Giovannelli et al.
    The genome of Thermovibrio ammonificans encodes ancestral pathways (e.g., hydrogen oxidation) and more recently acquired ones (e.g., nitrate reduction) and a hybrid pathway for CO2 fixation.
