However, empirical evidence remains scarce. Leveraging the prospective cohort of Beijing Child and Adolescent Metabolic Syndrome study (BCAMS), we investigated the blood DNA methylation signatures associated with childhood obesity and the future risk of cardiac hypertrophy in young adults, confirming causality with Mendelian randomization (MR). The BCAMS study followed children into adulthood. Data including blood DNA methylation profiles, along with lifestyles, blood levels of 7 adipokines and 32 amino acids were collected at baseline. Echocardiographic measurements were assessed at the 10-year follow-up. Enrichment and correlation analyses were performed, and two-sample MR analyses involving 105,268 participants from European biobanks were employed to infer causality. Cross-sectionally, we identified 376 differentially methylated sites between children with obesity and normal-weight controls (<em>n</em>=25), particularly within genes enriched in the cardiomyopathy pathway. Longitudinally, 11 childhood obesity-associated methylation sites, especially cg25835058 (<em>KAZN</em>), cg01362389 (<em>TDH</em>) and cg12099423 (<em>SLC17A9</em>), showed strong correlations with left ventricular index (LVMI) at the 10-year follow-up (<em>P</em>&lt;.0017). Additionally, these sites were associated with traditional risk factors, notably glutamine, which displayed strongest protective association with LVMI (−1.72g/m^2.7 per 1SD increase, <em>P</em>&lt;.001) when validated with the entire cohort (<em>n</em>=326). MR analysis confirmed the significant correlation between cg12099423 methylation levels and <em>SLC17A9</em> expression, and the causality between gene expression levels (<em>KAZN, TDH, SLC17A9</em>) and LVMI.

While only a limited number of studies have implicated epigenetic roles in the gut-brain axis, this review explores how gut microbiome might impact various brain-based epigenetic mechanisms, including DNA methylation, histone modification, ncRNA and RNA methylation, notably in the context of the specific neural complications. Among the epigenetic mechanisms, histone acetylation was most well-studied with respect to its relationships with gut microbiome, exerting a dynamic influence on gene expression in the brain. Furthermore, the pathways connecting gut bacteria to neuroepigenome were summarized, highlighting the roles of metabolites such as butyrate, propionate, acetate, lactate, and folate. Of particular interest, the roles of butyrate are emphasized due to their outstanding inhibitory activity towards histone deacetylases (HDACs), among other mechanisms. It is worth noting that some indirect gut-brain pathways may also be associated with the interplay between microbiome and neuroepigenome, while IL-6 has been found to effectively transmit microbe-derived signals to histone methylation in brains. Finally, we recapitulate the future perspectives critical to understanding this gut-brain crosstalk, such as clarifying the cause-and-effect relationship, bacterial cross-feeding within the gut, and the mechanisms underlying the site-specific histone modification in the brain. Together, this review attempts to consolidate our current knowledge about the “microbiome-neuroepigenome interplay” and propose a conceptual pathway to decipher the gut-brain axis in various neurological conditions.</div></div>","PeriodicalId":16618,"journal":{"name":"Journal of Nutritional Biochemistry","volume":"144 ","pages":"Article 109961"},"PeriodicalIF":4.8,"publicationDate":"2025-05-22","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"144142761","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":2,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Correlation between lung and gut microbiota was assessed. To further explore the role of intestinal flora, a depletion model was established using antibiotics (ABX). Our results indicated that 1,25(OH)₂D₃ alleviated LPS-induced ALI, as evidenced by reduced pathological damage, downregulated expression of proinflammatory cytokines (IL-1β, IL-6, TNF-α), increased levels of anti-inflammatory cytokine (IL-10), and suppressed TLR4/NF-κB and JNK pathways. LPS reduced α diversity and altered β diversity and composition of intestinal microbes, which were partially reversed by 1,25(OH)₂D₃ intervention. Notably, 1,25(OH)₂D₃ enhanced gut microbiota diversity and elevated the relative abundance of <em>Muribaculaceae</em> and <em>Lachnospiraceae</em> genus. Importantly, depletion of gut flora with ABX eliminated the anti-inflammatory effects of 1,25(OH)₂D₃, including its inhibition of LPS-induced cytokine expressions and pathway activation. Although LPS did not significantly affect the diversity of lung microbiota, it seemed to change its composition and induced a significant correlation between intestinal and pulmonary microbial communities, which was attenuated by 1,25(OH)₂D₃.
