Emerging evidence suggests that TMAO may play a role in the pathogenesis of various kidney diseases, including acute kidney injury and chronic kidney disease. Research has demonstrated that heightened levels of TMAO are correlated with a heightened likelihood of kidney disease advancement and cardiovascular incidents among individuals with chronic kidney disease. Furthermore, TMAO has been observed to stimulate inflammation, oxidative stress, and fibrosis in animal models of kidney disease. Mechanistically, TMAO may contribute to kidney disease pathogenesis by inhibiting autophagy, activating the NLRP3 inflammasome, and inducing mitochondrial dysfunction. Therefore, targeting TMAO may represent a promising therapeutic strategy for the treatment of kidney diseases. Future studies are needed to further investigate the role of TMAO in kidney disease pathogenesis and to develop TMAO-targeted therapies for the prevention and treatment of kidney diseases.<\/jats:p>","DOI":"10.3389\/fcimb.2025.1488264","type":"journal-article","created":{"date-parts":[[2025,3,11]],"date-time":"2025-03-11T03:08:37Z","timestamp":1741662517000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":29,"title":["The microbial metabolite trimethylamine N-oxide and the kidney diseases"],"prefix":"10.3389","volume":"15","author":[{"given":"Jin-Qi","family":"Su","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiang-Qi","family":"Wu","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Qi","family":"Wang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Bo-Yang","family":"Xie","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cui-Yan","family":"Xiao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hong-Yong","family":"Su","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Ji-Xin","family":"Tang","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Cui-Wei","family":"Yao","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1965","published-online":{"date-parts":[[2025,3,11]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"263","DOI":"10.17179\/excli2022-5617","article-title":"Optimization of enzyme-linked immunosorbent assay kit protocol to detect trimethylamine N-oxide levels in humans","volume":"22","author":"Aksoyalp","year":"2023","journal-title":"EXCLI J."},{"key":"B2","doi-asserted-by":"publisher","first-page":"89","DOI":"10.1038\/s41522-022-00352-6","article-title":"Host-microbiome interactions: Gut-Liver axis and its connection with other organs","volume":"8","author":"Anand","year":"2022","journal-title":"NPJ biofilms microbiomes"},{"key":"B3","doi-asserted-by":"publisher","first-page":"5843","DOI":"10.1038\/s41467-023-39824-4","article-title":"Evidence of a causal and modifiable relationship between kidney function and circulating trimethylamine N-oxide","volume":"14","author":"Andrikopoulos","year":"2023","journal-title":"Nat.
