Here, we show that murine hepatic stellate cells (HSCs) and their abundantly expressed plasmalemma vesicle-associated protein (PLVAP) control hepatic substrate preference for fasting energy metabolism. HSC-specific ablation of PLVAP in mice elevated hepatic insulin signaling and improved glucose tolerance. Fasted HSC PLVAP knockout mice showed suppressed hepatic fatty acid esterification into di- and triacylglycerols, shifting fasting metabolism from fatty acid oxidation to reliance on carbohydrates. By super-resolution microscopy, we localized HSC PLVAP to caveolae residing along the sinusoidal lumen, supporting a role for HSCs and PLVAP-diaphragmed caveolae in normal fasting metabolism of the liver.","PeriodicalId":9840,"journal":{"name":"Cell metabolism","volume":"84 1","pages":""},"PeriodicalIF":29.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532301","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Here, we reveal that glyoxylate, a metabolite originally evolved for alternative carbon utilization, functions as a signaling molecule to reprogram the host transcriptome and promote persister formation. Glyoxylate inhibits the DNA dioxygenase TET2, suppressing pro-inflammatory gene expression and attenuating host immune defense. Notably, stimulating TET2 activity with vitamin C or blocking glyoxylate production by Salmonella reduces bacterial antibiotic resistance and improves infection treatment outcomes. Beyond its metabolic role, glyoxylate emerges as a regulator of host-pathogen interactions, while TET2 plays a critical role in preventing bacterial persistence. Our findings suggest that targeting glyoxylate production or enhancing TET2 activity offers promising therapeutic strategies to combat bacterial persistence and enhance the efficacy of antibiotic treatments.","PeriodicalId":9840,"journal":{"name":"Cell metabolism","volume":"37 1","pages":""},"PeriodicalIF":29.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532286","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Protein expression profiles, mitochondrial energetics, metabolomics and fluxomics data in cell line, xenograft, and patient-derived xenograft systems revealed that concerted reprogramming of metabolic pathways (including glutaminolysis, glycolysis, TCA cycle, electron transport chain [ETC], and transsulfuration), along with an immediate cytoprotective response to drug-induced oxidative stress, underpins drug-tolerant persister cancer cell survival. Realignment of cysteine (Cys) metabolism, in particular an immediate upregulation of cystathionine-γ-lyase (CSE), was vital in persister cells. The oxidative cellular environment, drug-induced elevated cystine uptake and oxidative Cys catabolism, increased intracellular cystine/Cys ratios, thereby favoring cystine as a CSE substrate. This produces persulfides and hydrogen sulfide to protect protein thiols and support elevated energy demand in persister cells. Combining BRAF V600E inhibitors with CSE inhibitors effectively diminished proliferative relapse in culture models and increased progression-free survival of xenografted mice. This, together with induced CSE expression in patient samples under BRAF-V600E-inhibition, reveals an approach to increase BRAF-V600E-targeted therapeutic efficacy.","PeriodicalId":9840,"journal":{"name":"Cell metabolism","volume":"34 1","pages":""},"PeriodicalIF":29.0,"publicationDate":"2025-03-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143532400","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we identify sphingomyelin phosphodiesterase 3 (SMPD3) as a key driver of hepatic ceramide accumulation through increasing sphingomyelin hydrolysis at the cell membrane. Hepatocyte-specific Smpd3 gene disruption or pharmacological inhibition of SMPD3 alleviates MASH, whereas reintroducing SMPD3 reverses the resolution of MASH. Although healthy livers express low-level SMPD3, lipotoxicity-induced DNA damage suppresses sirtuin 1 (SIRT1), triggering an upregulation of SMPD3 during MASH. This disrupts membrane sphingomyelin-ceramide balance and promotes disease progression by enhancing caveolae-dependent lipid uptake and extracellular vesicle secretion from steatotic hepatocytes to exacerbate inflammation and fibrosis. Consequently, SMPD3 acts as a central hub integrating key MASH hallmarks. Notably, we discovered a bifunctional agent that simultaneously activates SIRT1 and inhibits SMPD3, which shows significant therapeutic potential in MASH treatment. These findings suggest that inhibition of hepatic SMPD3 restores membrane sphingolipid metabolism and holds great promise for developing novel MASH therapies.","PeriodicalId":9840,"journal":{"name":"Cell metabolism","volume":"24 1","pages":""},"PeriodicalIF":29.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495774","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Mechanistic studies reveal that EHBP1 promotes sortilin-mediated PCSK9 secretion, leading to LDL receptor (LDLR) degradation, decreased LDL uptake, and reduced TAZ, a fibrogenic effector. At a cellular level, EHBP1 deficiency affects the intracellular localization of retromer, a protein complex required for sortilin stabilization. Our therapeutic approach to stabilizing retromer is effective in mitigating MASH fibrosis. Moreover, we show that the tumor necrosis factor alpha (TNF-α)/peroxisome proliferator-activated receptor alpha (PPARα) pathway suppresses EHBP1 in MASH. These data not only provide mechanistic insights into the role of EHBP1 in cholesterol metabolism and MASH fibrosis but also elucidate an interplay between inflammation and EHBP1-mediated cholesterol metabolism.","PeriodicalId":9840,"journal":{"name":"Cell metabolism","volume":"27 1","pages":""},"PeriodicalIF":29.0,"publicationDate":"2025-02-26","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143495773","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

However, the complex regulatory relationship between them remains largely unclear. Here, we find that loss of aldo-keto reductase 1D1 (AKR1D1) promotes the accumulation of isolithocholic acid (iso-LCA) through gut microbiome dysregulation, thereby impairing the cytotoxic function of natural killer (NK) cells and leading to the accelerated development of hepatocellular carcinoma (HCC). Mechanistically, AKR1D1 deficiency leads to an increased proportion of Bacteroidetes ovatus (B. ovatus), which breaks down chenodeoxycholic acid (CDCA) into iso-LCA. Moreover, accumulated iso-LCA impairs the antitumor activity of hepatic NK cells in a phosphorylated-CREB1 (p-CREB1)-dependent manner. The potassium-sparing diuretic spironolactone treatment significantly enhances the inhibitory effect of anti-PD1 antibody on HCC progression by targeting iso-LCA-mediated tumor immune escape. Taken together, our results uncover a previously unappreciated link between AKR1D1 and HCC and suggest that targeting iso-LCA produced by B. ovatus might be a promising strategy to activate NK cell cytotoxicity to treat HCC.","PeriodicalId":9840,"journal":{"name":"Cell metabolism","volume":"28 1","pages":""},"PeriodicalIF":29.0,"publicationDate":"2025-02-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143486524","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":1,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
