Yong et al. highlight how sampling conditions affect metabolic profile in renal cancer, showing that prolonged ischemic exposure disrupts tissue metabolome stability and masks important phenotypes, such as suppressed gluconeogenesis.

Here, the authors show that physiological alpha-synuclein supports mitochondrial ATP homeostasis via interactions with ATP synthase and AK2, whereas its disease-linked mutants, truncated forms, and aggregates lose these interactions.

Inhibition of the tricarboxylic acid cycle enzyme fumarate hydratase leads to deregulation of cytokine production in macrophages, which has implications in human diseases such as systemic lupus erythematosus.

In 1923, Otto Warburg published his landmark study, in which he described his seminal observations related to metabolic shifts in cancer, often referred to as the Warburg effect. His work laid the foundation for an understanding of how metabolic reconfiguration contributes to cancer onset and progression. Several researchers in the field share their thoughts on what this discovery means to them and how it has inspired their scientific journey.

Fumarate metabolism regulates the innate immune response through a mechanism in which high levels of fumarate result in the generation of mitochondrial-derived vesicles and the release of mitochondrial DNA into the cytosol, which activates inflammatory pathways.

Metformin may serve as a non-toxic intervention to inhibit mitochondrial metabolism and slow DNMT3A-R882 clonal haematopoiesis expansion, thus delaying or averting progression to acute myeloid leukaemia.

Certo, Pontarini et al. provide insight into the metabolic requirements of ectopic lymphoid structure (ELS) assembly in the context of autoimmunity, and show that blocking lactate uptake by SLC5A12 offers therapeutic benefits in a mouse model of Sjögren’s disease.

Fumarate hydratase (FH) mutations are associated with renal cancer. Here, Zheng et al. use metabolomic and analytical chemistry approaches to reveal that fumarate accumulated due to FH loss covalently modifies intracellular glutathione, leading to oxidative stress and senescence.

Blocking mitochondrial complex I in pro-inflammatory microglia protects the central nervous system against neurotoxic damage and improves functional outcomes in vivo in an animal disease model.

Reducing the competitive advantage conferred by driver mutations can abrogate expansions of mutant clones in healthy tissue in mice. This suggests ways to prevent cancer and other diseases that are associated with somatic mutations in humans.

Yeast exhibit oscillations that share features with circadian rhythms. The authors show that bioenergetic constraints promote oscillatory behaviour: resources are stored until supplies can support translational bursting, this is licensed by ion transport and release from membrane-less compartments.

Optimized Ullmann coupling reaction of heterotriangulene precursors allows the synthesis of two-dimensional π-conjugated polymers with ordered domains larger than 100 × 100 nm² showing both Dirac cones and flat bands in their electronic structure.

Andrade et al. show that FOXO1 regulates mitochondrial metabolism to stimulate the production of the metabolite S-2HG to promote acquisition of a quiescent endothelial state.

Metabolomics analysis of neural stem/progenitor cell-derived extracellular vesicles reveals asparaginase activity catalyzed by L-asparaginase-like protein 1.

Gammage and colleagues find that mitochondrial DNA mutations induce alterations in redox metabolism, a remodeled tumor microenvironment characterized by a loss of neutrophils and consequently enhanced responses to immunotherapy in melanoma.

Halbrook et al. report two metabolic subgroups of pancreatic ductal adenocarcinoma cells defined by differential integrated stress response and asparagine production that permit symbiosis and phenformin resistance.

Casey et al. explore the basic mechanisms of mitochondrial superoxide production and its impact on interleukin-1β production in LPS-treated macrophages.

Understanding the mechanisms associated with cancer metastasis may help control cancer progression. Here the authors investigate the metabolism of metastasis initiating cells in breast cancer and show that their metastatic ability relies on fatty acid oxidation and the oxidative tricarboxylic acid cycle, which in turn regulates acetyl-CoA generation and the acetylation of histones on EMT related genes.

Winter and colleagues demonstrate that metabolic adaptation to nutrient stress in the tumor microenvironment of pancreatic cancer leads to a dependency on IDH1, which is therapeutically actionable regardless of IDH1 mutation status.

Mouse models of muscle injuries and ageing characterized by low levels of intra-tissue glutamine are ameliorated by macrophage-specific deletion or systemic pharmacological inhibition of glutamate dehydrogenase 1, which results in constitutively high activity of glutamine synthetase.

The metabolite methylthioadenosine (MTA) inhibits PRMT5. Therefore, MTA accumulation due to MTA phosphorylase (MTAP) deletion has been proposed as a vulnerability for PRMT5-targeted therapy in cancer. Here, the authors show that MTA does not accumulate in MTAP-deficient cancer cells but is secreted and metabolized by MTAP-intact cells in the tumour microenvironment.

Prostate cancer cells depend on MTAP, the rate-limiting enzyme involved in the methionine salvage pathway, to cope with increased polyamine biosynthesis. Here, the authors show that inducing upregulation of polyamine biosynthesis and targeting MTAP synergize to increase apoptosis in prostate cancer cells.

Fournier's gangrene is a life-threatening urological emergency, which requires prompt treatment with fluid resuscitation, debridement, and reconstruction. In this Review, Hagedorn and Wessells describe the contemporary management of Fournier's gangrene, and discuss prognostic tools, therapeutics, and follow-up care of this rare but debilitating disorder.

A single-center, observational cohort study assessing the mitochondrial bioenergetics of left ventricular tissue from patients undergoing coronary artery bypass grafting surgery suggests that viable myocardium has global alterations in bioenergetics and transcriptome without large regional differences between areas with or without inducible ischemia.

Gastrointestinal stromal tumours can be initiated by gain-of-function mutations of the KIT or PDGFRA oncogenes but also by loss of the metabolic complex succinate dehydrogenase (SDH), which leads to DNA hypermethylation; this study shows that in SDH-deficient tumours, displacement of CTCF insulators by DNA methylation activates oncogene expression, illustrating how epigenetic alterations can drive oncogenic signalling in the absence of kinase mutations.

Primary cilia are shown to adjust length in response to cellular nutrient availability, with a special role for glutamine-mediated anaplerosis via the enzyme ASNS, which was found to be located at the base of cilia. Consistently, cells lacking cilia show an altered response to glutamine during metabolic stress.

The cellular effects of cold preservation in heart transplantation and how warm ischaemia leads to damage are unclear. Here the authors identify succinate accumulation as a major damaging metabolic change in warm ischaemia.

WebTreatment of lipopolysaccharide-activated macrophages with the cell-permeable itaconate derivative 4-octyl itaconate activates the anti-inflammatory transcription factor Nrf2 by alkylating key cysteine residues on the KEAP1 protein.

A metabolomics study on the ischaemic heart identifies succinate as a metabolite that drives the production of reactive oxygen species and contributes to ischaemia-reperfusion injury; pharmacological inhibition of succinate accumulation ameliorates ischaemia-reperfusion injury in a mouse model of heart attack and a rat model of stroke.

Bidault et al. find that interleukin-4 activates SREBP1 to promote de novo lipogenesis that consumes NADPH to drive alternative activation of macrophages through the accumulation of reactive oxygen species.

The M2 isoform of pyruvate kinase (PKM2) is a key glycolytic enzyme that is overexpressed in cancer cells; here, serine is shown to bind to and directly activate PKM2, and the resulting reduction in enzyme activity under serine-deprivation conditions is shown to lead to the diversion of glucose-derived carbon to promote serine biosynthesis required for cell proliferation.

Succinate is identified as a metabolite in innate immune signalling, which leads to enhanced interleukin-1β production during inflammation.

Mutant Kras lung tumours are not a single disease but comprise two classes of tumours with distinct metabolic profiles, prognosis and therapeutic susceptibility, which can be discriminated by their relative mutant Kras allelic content.
