Although evidence links gut microbiota composition to cancer progression, its precise role in modulating treatment responses remains unclear. In this Review, we summarize current knowledge on the gut microbiome’s involvement in cancer, covering its role in tumour initiation and progression, interactions with chemotherapy, radiotherapy and targeted therapies, and its influence on cancer immunotherapy. We discuss the impact of microbial metabolites on immune responses, the relationship between specific bacterial species and treatment outcomes, and potential microbiota-based therapeutic strategies, including dietary interventions, probiotics and faecal microbiota transplantation. Understanding these complex microbiota–immune interactions is critical for optimizing cancer therapies. Future research should focus on defining microbial signatures associated with treatment success and developing targeted microbiome modulation strategies to enhance patient outcomes.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"11 1","pages":""},"PeriodicalIF":20.8,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we determine that hyperglycaemia is a major cause for the development of anxiety disorders through a C–C motif chemokine ligand 2 (CCL2)-dependent mechanism. By adopting complementary strategies, we demonstrate that neuron-specific (not peripheral) CCL2 mediates anxiety-like behaviours in streptozotocin-induced diabetic mice. Mechanistically, high glucose levels induce Tonicity-responsive enhancer-binding protein (TonEBP)-dependent CCL2 expression in neurons, leading to microglial activation in a paracrine manner. Similar phenotypes are also observed in high-fat diet-induced diabetic mice, independent of insulin signalling. Furthermore, we reveal that neuronal CCL2 in the medial prefrontal cortex and ventral hippocampus synergistically induces anxiety-like behaviours, indicating brain region-specific effects on diabetic mice. Finally, we confirm that the neuronal TonEBP–CCL2 axis and inflammatory pathways are both upregulated in patients with diabetes. Conclusively, neuronal CCL2 is specifically increased by hyperglycaemia and contributes to anxiety disorders, providing additional insights into the link between diabetes and mental health disorders.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"8 1","pages":""},"PeriodicalIF":20.8,"publicationDate":"2025-05-06","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143909772","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cancer cells co-express two distinct NAD kinases that differ by localization (NADK, cytosol; NADK2, mitochondria). CRISPR screens performed across hundreds of cancer cell lines indicate that both are dispensable for growth in conventional culture media. By contrast, NADK deletion impaired cell growth in human plasma-like medium. Here we trace this conditional NADK dependence to the availability of folic acid. NADPH is the preferred cofactor of dihydrofolate reductase (DHFR), the enzyme that mediates metabolic activation of folic acid. We find that NADK is required for enabling cytosolic NADPH-driven DHFR activity sufficient to maintain folate-dependent nucleotide synthesis under low folic acid conditions. Our results reveal a basis for conditional NADK essentiality and suggest that folate availability determines whether DHFR activity can be sustained by alternative electron donors such as NADH.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"44 1","pages":""},"PeriodicalIF":20.8,"publicationDate":"2025-05-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143898124","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, while GIPR agonism decreases body weight and food intake in a GLP-1R-independent manner via GABAergic GIPR+ neurons, it remains unclear whether GIPR antagonism affects energy metabolism via a similar mechanism. Here we show that the body weight and food intake effects of GIPR antagonism are eliminated in mice with global loss of either Gipr or Glp-1r but are preserved in mice with loss of Gipr in either GABAergic neurons of the central nervous system or peripherin-expressing neurons of the peripheral nervous system. Single-nucleus RNA-sequencing shows opposing effects of GIPR agonism and antagonism in the dorsal vagal complex, with antagonism, but not agonism, closely resembling GLP-1R signalling. Additionally, GIPR antagonism and GLP-1R agonism both regulate genes implicated in synaptic plasticity. Collectively, we show that GIPR agonism and antagonism decrease body weight via different mechanisms, with GIPR antagonism, unlike agonism, depending on functional GLP-1R signalling.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"17 1","pages":""},"PeriodicalIF":20.8,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884803","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we demonstrate that a peptide–antibody conjugate that blocks GIPR while simultaneously activating GLP-1R (GIPR-Ab/GLP-1) requires both CNS GIPR and CNS GLP-1R for maximal weight loss in obese, primarily male, mice. Moreover, dulaglutide produces greater weight loss in CNS GIPR knockout (KO) mice, and the weight loss achieved with dulaglutide + GIPR-Ab is attenuated in CNS GIPR KO mice. Wild-type mice treated with GIPR-Ab/GLP-1 and CNS GIPR KO mice exhibit similar changes in gene expression related to tissue remodelling, lipid metabolism and inflammation in white adipose tissue and liver. Moreover, GIPR-Ab/GLP-1 is detected in circumventricular organs in the brain and activates c-FOS in downstream neural substrates involved in appetite regulation. Hence, both CNS GIPR and GLP-1R signalling are required for the full weight loss effect of a GIPR-Ab/GLP-1 peptide–antibody conjugate.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"37 1","pages":""},"PeriodicalIF":20.8,"publicationDate":"2025-04-29","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143884809","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here we used embryonic stem (ES) cells as a model system to understand how changes in intracellular metabolic networks that characterize cell state transitions affect reliance on exogenous nutrients. We find that ES cells in the naive ground state of pluripotency increase uptake and reliance on exogenous pyruvate through the monocarboxylate transporter MCT1. Naive ES cells, but not their more committed counterparts, rely on exogenous pyruvate even when other sources of pyruvate (glucose, lactate) are abundant. Pyruvate dependence in naive ES cells is a consequence of their elevated mitochondrial pyruvate consumption at the expense of cytosolic NAD+ regeneration. Indeed, across a range of cell types, increased mitochondrial pyruvate consumption is sufficient to drive demand for extracellular pyruvate. Accordingly, restoring cytosolic NAD+ regeneration allows naive ES cells to tolerate pyruvate depletion in diverse nutrient microenvironments. Together, these data demonstrate that intracellular metabolic gradients dictate uptake and reliance on exogenous pyruvate and highlight mitochondrial pyruvate metabolism as a metabolic vulnerability of naive ES cells.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"84 1","pages":""},"PeriodicalIF":20.8,"publicationDate":"2025-04-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143880755","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The hepatocytes perform distinct metabolic functions depending on their location within the lobule. Single-cell analysis of hepatocytes across the liver lobule demonstrates that gluconeogenic gene expression is relatively low in the fed state and gradually increases in the periportal hepatocytes during the initial fasting period. As fasting progresses, pericentral hepatocyte gluconeogenic gene expression and gluconeogenic activity also increase and, following entry into a starvation state, the pericentral hepatocytes show similar gluconeogenic gene expression and activity to the periportal hepatocytes. In parallel, starvation suppresses canonical β-catenin signalling and modulates the expression of pericentral and periportal glutamine synthetase and glutaminase, respectively, resulting in enhanced incorporation of glutamine into glucose. Thus, hepatocyte gluconeogenic gene expression and glucose production are spatially and temporally plastic across the liver lobule, underscoring the complexity of defining hepatic insulin resistance and glucose production on a whole-organ level, as well as for a particular fasted or fed condition.","PeriodicalId":19038,"journal":{"name":"Nature metabolism","volume":"53 1","pages":""},"PeriodicalIF":20.8,"publicationDate":"2025-04-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143872777","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
