A population-based cross-sectional \"Know Your Heart\" study (2015-2017, participants aged 35-69 years) included a health examination and gut microbiota analysis ( <i>n</i> = 685). Participants were divided into four metabolic phenotypes: metabolically healthy non-obese (MHN), metabolically unhealthy non-obese (MUN), metabolically healthy obese (MHO), and metabolically unhealthy obese (MUO). Analyses were performed using RStudio software (v.4.2.0) with the vegan and phyloseq packages (v.1.42.0) for microbiota analysis. The sample was distributed across phenotypes as follows: MHN (47.6%), MUN (22.1%), MHO (10.4%), and MUO (19.9%). Beta-diversity analysis revealed significant differences in overall microbiome composition between MUO and MHN participants, while alpha-diversity did not differ significantly across phenotypes. The MHN group was characterized by a higher abundance of beneficial commensals such as <i>Christensenellaceae R-7</i> group, <i>Ruminococcaceae UCG-005</i>, and <i>Eubacterium xylanophilum</i> group, which are taxa previously associated with metabolic health and longevity. In contrast, the MUO group showed an increased abundance of <i>Streptococcus salivarius</i> and <i>Negativibacillus</i>, taxa linked to gut dysbiosis and metabolic disorders. <i>Blautia spp</i>. emerged as a major hub in the microbiota of obese participants, consistent with its reported association with visceral fat. In conclusion, microbial composition was similar in obese participants despite metabolic dysfunction, whereas unidirectional taxonomic shifts were observed in those with metabolic dysfunction alone. The differences in the predominance of microbial taxa across metabolic phenotypes suggest that these taxa have a role in the development of metabolic disorders and obesity.</p>","PeriodicalId":15061,"journal":{"name":"Journal of Biomedical Research","volume":" ","pages":"1-17"},"PeriodicalIF":3.7,"publicationDate":"2025-10-25","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC13620460/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"145458596","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Current therapeutic options for PF remain limited, highlighting the urgent need to elucidate its molecular mechanisms in order to develop novel treatment strategies. Recent studies have revealed that autophagy and ferroptosis, two critical cell death pathways, engage in intricate crosstalk mechanisms that regulate the pathogenesis of PF. Autophagy maintains cellular homeostasis by mediating lysosome-dependent degradation, whereas ferroptosis is characterized by iron-dependent lipid peroxidation. The interplay between autophagy and ferroptosis plays a pivotal role in modulating fibrosis progression. However, the mechanistic interactions between autophagy and ferroptosis in PF remain poorly understood, particularly regarding their bidirectional crosstalk and their unique role in PF progression.

Understanding the molecular mechanisms of HCC could provide insight into new therapies. Emerging studies indicate the important role of long-noncoding RNAs (lncRNAs) in the pathogenesis of HCC. The expression of the well-studied lncRNA taurine upregulated gene 1 ( <i>TUG1</i>) is upregulated in HCC tissues, but its transcriptomic effects in HCC cells remain unexplored. We established <i>TUG1</i>-knockdown and control HCC cells for RNA-seq experiments. KEGG analysis revealed glycolysis as the top enriched pathway upon <i>TUG1</i> silencing. Accordingly, <i>TUG1</i>-depleted HCC cells showed impairments in glucose uptake, ATP synthesis, and lactate production. Clinical HCC tissue data revealed positive gene expression correlations between <i>TUG1</i> and several glycolysis-related genes. To identify a molecular function of <i>TUG1</i> in glycolysis, we explored the competing endogenous model and used bioinformatic tools to find the five microRNAs (miRNAs) that had the most binding sites for <i>TUG1</i>.
