DNA was initially extracted from cultured bacterial consortia in the polar soils and recombined into plasmid vectors and then transformed into <i>Escherichia coli</i> (<i>E. coli</i>) for the subsequent screening of antibiotic resistance. Consequently, we identified 671 novel polar ARGs with experimentally verified resistance against multiple clinical antibiotics (cefotaxime, folate synthesis inhibitors, and clindamycin). Bioinformatics analysis revealed that novel polar ARGs had limited mobility and dissemination potential and were seldom carried by human bacterial pathogens. Overall, this study offers a comprehensive perspective on previously overlooked novel ARGs in polar regions, advancing our understanding of environmental resistomes.\u0000\u0000 <figure>\u0000 <div><picture>\u0000 <source></source></picture><p></p>\u0000 </div>\u0000 </figure></p>","PeriodicalId":73342,"journal":{"name":"iMeta","volume":"4 4","pages":""},"PeriodicalIF":23.7,"publicationDate":"2025-08-03","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://onlinelibrary.wiley.com/doi/epdf/10.1002/imt2.70069","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144888301","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}

Meta-analysis with prospective cohort studies further confirms that elevated HDL is a protective factor for ESRD outcomes. In severe renal injury models, including 5/6 nephrectomy and apolipoprotein E-deficient (<i>ApoE<sup>−/−</sup></i>) mice, probiotics restored cardiac function, mirroring the cardioprotective effects seen in humans. Mechanistic studies indicate that probiotics enhance intestinal HDL3 production through the insulin-mediated SP1(P)-CYP27A-LXRα/β-ABCA1 pathway, thereby maintaining HDL metabolic homeostasis.

Propensity score matching (PSM) was utilized to mitigate baseline variability. Univariate and multivariate Cox analyses were used to identify potential prognostic factors. Biomarker assessment comprised immunohistochemistry and single-cell RNA sequencing. After PSM, Neoimmu-CMT demonstrated superior efficacy over NAC-CMT and comparability to TMT. A clinical complete response to neoadjuvant treatment and lower clinical T stage were positive prognostic factors for Neoimmu-CMT.

Recent advancements in gut microbiota (GM) research have shed light on the intricate relationship between GM and TB, suggesting that GM alterations may influence host susceptibility, disease progression, and response to antituberculosis drugs. This review systematically synthesizes and analyzes the current research progress on the relationship between GM and TB, focusing on six key aspects: (1) bidirectional effects between GM dynamics and TB progression; (2) the interaction between GM and anti-TB drugs; (3) GM and TB immune response; (4) GM as a potential target for diagnosis and treatment of TB; (5) multi-omics and artificial intelligence (AI) technologies in GM-TB research; (6) current challenges and future directions in GM-TB research. We highlight the bidirectional nature of the GM–TB interaction, where MTB infection can lead to GM dysbiosis, and changes can affect the host's immune response, contributing to TB onset and progression. Advanced molecular techniques, such as next-generation sequencing and metagenomics, along with AI, play pivotal roles in elucidating these complex interactions. Future research directions include investigating the relationship between GM and TB vaccine efficacy, exploring GM's potential in TB prevention, developing microbiome-based diagnostic and prognostic tools, and examining the role of GM in TB recurrence. By addressing these areas, we aim to provide a comprehensive perspective on the latest advancements in GM and TB research and offer insights for future studies and clinical applications.
