Current understanding of the intricate fiber-microbe-disease tripartite relationship remains fragmented and elusive, urging a systematic investigation. Here, we focused on microbiota disturbance as a robust index to mitigate various confounding factors and developed the Bio-taxonomic Hierarchy Weighted Aggregation (BHWA) algorithm to integrate multi-taxonomy microbiota disturbance data, thereby illuminating the complex relationships among dietary fiber, microbiota, and disease. By leveraging microbiota disturbance similarities, we (1) classified 32 types of dietary fibers into six functional subgroups, revealing correlations with fiber solubility; (2) established associations among 161 diseases, uncovering shared microbiota disturbance patterns that explain disease co-occurrence (e.g., type II diabetes and kidney diseases) and distinct microbiota patterns that discern symptomatically similar diseases (e.g., inflammatory bowel disease and irritable bowel syndrome); (3) designed a body-site-specific microbiota disturbance scoring scheme, computing a disturbance score (<i>DS</i>) for each disease and highlighting the pronounced capacity of Crohn's disease to disturb gut microbiota (<i>DS</i> = 14.01) in contrast with food allergy's minimal capacity (<i>DS</i> = 0.74); (4) identified 1659 fiber-disease associations, predicting the potential of dietary fiber to modulate specific microbiota changes associated with diseases of interest; (5) established murine models of inflammatory bowel disease to validate the preventive and therapeutic effects of arabinoxylan that notably perturbed the <i>Bacteroidetes</i> and <i>Firmicutes</i> phyla, as well as the <i>Bacteroidetes</i> and <i>Lactobacillus</i> genera, aligning with our model predictions.

Here, a survey across soils with varying pH values (ranging from 4.4 to 9.7) was conducted to assess how comammox <i>Nitrospira</i> perform under different pH conditions. Results showed that comammox <i>Nitrospira</i> dominate ammonia oxidation in weakly acidic soils, functioning as a K-strategy species characterized by slow growth and stress tolerance.

Additionally, we used DNA stable-isotope probing (DNA-SIP) to demonstrate its response to pH fluctuations to reflect how it responds to the decrease in pH. Results confirmed that comammox <i>Nitrospira</i> became dominant ammonia oxidizers in the soil after the decrease in pH.

We propose that non-differential microbes contribute to hypertension through their ecological interactions, as defined by co-abundances (pairs of microbes exhibiting correlated abundance patterns). Using gut microbiome data from the Guangdong Gut Microbiome Project, which includes 2355 hypertensive and 4644 non-hypertensive participants across 14 regions, we identified replicable hypertension-related microbial interactions.

These findings emphasize the importance of microbial interactions in hypertension pathogenesis and propose a novel perspective for microbiome-based therapeutic strategies.</p>","PeriodicalId":73342,"journal":{"name":"iMeta","volume":"4 1","pages":""},"PeriodicalIF":23.7,"publicationDate":"2025-01-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/imt2.268","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497205","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Herein, we used targeted metabolomics and machine learning algorithms to develop an oxylipin-based risk model to accurately predict recurrent major adverse cardiovascular events (MACE) after STEMI in two independent prospective cohorts with 2 years of follow-up. The in vivo effects of significant oxylipin predictors were explored via a murine myocardial ischemia‒reperfusion model and functional metabolomics. Among the 130 plasma oxylipins detected in discovery cohort (<i>n</i> = 645), patients with and without recurrent MACE exhibited significant differences in a variety of oxylipin subclasses. We constructed an oxylipin-based prediction model that showed powerful performance in predicting recurrent MACE in the discovery cohort (predictive accuracy: 91.5%). The predictive value of the oxylipin marker panel was confirmed in an independent external validation cohort (predictive accuracy: 89.9%; <i>n</i> = 401). Furthermore, we found that the anti-inflammatory/pro-resolving oxylipin (ARO) predictor panel showed better prognostic performance than the pro-inflammatory oxylipin predictor panel in both cohorts. Compared with the treatment of pro-inflammatory oxylipin predictor panel, combined treatment of six ARO predictors, including 14,15 epoxy-eicosatrienoic acid, 14(15)-epoxy-eicosatetraenoic acid, 12,13-epoxy-octadecenoic acid, lipoxin A4, resolving D1, and 6 keto-prostaglandin F1 showed significant cardiac activities and synergistic metabolic actions in myocardial infarction‒reperfusion model mice. We also mechanistically identified an important role of ARO predictors in restraining ceramide/lysophosphatidylcholine synthesis and inhibiting inflammatory responses. Overall, the present study depicted the landscape of oxylipin profiles in the largest panel of STEMI patients worldwide. Our results also highlight the great potential of bioactive oxylipins in prognostic prediction and therapeutics after STEMI.</p>","PeriodicalId":73342,"journal":{"name":"iMeta","volume":"4 1","pages":""},"PeriodicalIF":23.7,"publicationDate":"2025-01-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/imt2.266","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"143497204","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
