However, current molecular mechanism investigations have remained limited to single-omics approaches that lack comprehensive multi-omics explorations. We integrate high-depth data-independent acquisition (DIA) proteomics and untargeted metabolomics to analyze serum samples from healthy controls (n =28), AGA (n = 31), and CGA (n = 14) patients to address this gap. Through differential expression analysis, we identified nine persistently dysregulated pivotal proteins with robust discriminative capacity, including the urate excretion regulator ZBTB20 and inflammation\/immune-related proteins (GUCY1A2, CNDP1, LYZ, SERPINA5, GSN). Additionally, 11 consistently altered core metabolites with diagnostic potential were detected, indicating perturbations in sex hormones, thyroid hormones, gut microbiota-derived metabolites, environmental exposures, and nutritional factors. Multi-omics KEGG enrichment analysis highlighted thyroid hormone synthesis, AMPK signaling pathway, and taurine and hypotaurine metabolism as central pathways. Correlation network analysis further revealed significant immune dysregulation, illustrating an evolution from acute immune activation to chronic inflammation during AGA-to-CGA progression. Our study establishes that a coordinated disruption of the thyroid hormone\u2013AMPK\u2013taurine metabolic axis and concomitant immune microenvironment remodeling is associated with chronic gout development. These findings provide critical targets for developing early diagnostic indicators and targeted interventions for CGA.<\/jats:p>","DOI":"10.3390\/cells15010041","type":"journal-article","created":{"date-parts":[[2025,12,26]],"date-time":"2025-12-26T02:07:58Z","timestamp":1766714878000},"page":"41","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Multi-Omics Mechanism of Chronic Gout Arthritis and Discovery of the Thyroid Hormone\u2013AMPK\u2013Taurine Metabolic Axis"],"prefix":"10.3390","volume":"15","author":[{"given":"Guizhen","family":"Zhu","sequence":"first","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-8081-7237","authenticated-orcid":false,"given":"Yuan","family":"Luo","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Xiangyi","family":"Zheng","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Zhusong","family":"Mei","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Qiao","family":"Ye","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jie","family":"Peng","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Fengsen","family":"Duan","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yueying","family":"Cui","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Peiyu","family":"An","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yangqian","family":"Song","sequence":"additional","affiliation":[{"name":"Rheumatology and Immunology Department, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Hongxia","family":"Li","sequence":"additional","affiliation":[{"name":"Rheumatology and Immunology Department, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Haitao","family":"Zhang","sequence":"additional","affiliation":[{"name":"Cardiovascular Department, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guangyun","family":"Wang","sequence":"additional","affiliation":[{"name":"Laboratory of Clinical Medicine, Air Force Medical Center, Air Force Medical University, People\u2019s Liberation Army of China, Beijing 100142, China"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2025,12,25]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Asghari, K.M., Zahmatyar, M., Seyedi, F., Motamedi, A., Zolfi, M., Alamdary, S.J., Fazlollahi, A., Shamekh, A., Mousavi, S.E., and Nejadghaderi, S.A.
