The aim of this study was to explore the mechanisms by which advanced age and alcohol exacerbate alcohol-induced liver injury.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Methods<\/jats:title>\n                  <jats:p>Two-to-three-month-old and twenty-to-twenty-two-month-old male C57BL\/6N mice were subjected to chronic-on-binge alcohol feeding (the Gao-binge model). Serum alanine aminotransferase, aspartate aminotransferase, and triglyceride content were determined using biochemical assays. The levels of lipogenesis, fatty acid-metabolizing proteins, inflammatory markers, mitochondrial and autophagy-related proteins, and senescence-associated proteins were determined by immunoblotting, immunohistochemistry, and real-time quantitative polymerase chain reaction (RT-qPCR). Liver tissues were also subjected to RNA sequencing and metabolomics analyses. Proteomics analysis was performed on serum samples. Tail-vein adenovirus-TFEB was injected to overexpress hepatic TFEB in 22-month-old C57BL\/6N male mice, followed by Gao-binge alcohol feeding.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Results<\/jats:title>\n                  <jats:p>Hepatic triglyceride content was significantly increased in aged, alcohol-fed mice, whereas serum ALT and AST levels remained relatively similar between alcohol-fed young and aged mice. Gao-binge alcohol increased the hepatic levels of diacylglycerol and acyl-carnitine species in both aged and young livers. RNA sequencing, proteomic analysis, and serum cytokine array analysis showed that inflammatory cytokines, including Ccr2, Cxcl1, and CCL6, and pro-inflammatory antibody fragments were increased in aged, alcohol-fed mice. Increased gene and protein expression of the senescent markers p21 and p27, along with increased senescent-associated (SA) \u03b2-galactosidase activity in ethanol-fed aged mice compared to young mice. Gene and protein expression of TFEB was downregulated in ethanol-fed young and aged animals, along with decreased levels of lysosomal ATPases and hepatic dipeptide content. Overexpression of TFEB in the livers of aged, Gao-binge-fed mice was associated with reduced Ly6G-positive cells, reduced protein levels of the innate immune mediators cGAS, IRF-7, IRF3, and NLRP3, and reduced caspase-1 activity as well as serum ALT levels.<\/jats:p>\n                <\/jats:sec>\n                <jats:sec>\n                  <jats:title>Conclusions<\/jats:title>\n                  <jats:p>Our findings indicate that advanced age perpetuates the detrimental effects of excessive alcohol consumption on various homeostatic processes and promotes steatosis and inflammation in the liver. Modulations in hepatic TFEB could be effective in mitigating pro-inflammatory signaling that occurs due to the synergistic effect of both heavy alcohol consumption and advanced age.<\/jats:p>\n                <\/jats:sec>","DOI":"10.64898\/2026.06.19.730442","type":"posted-content","created":{"date-parts":[[2026,6,22]],"date-time":"2026-06-22T12:55:15Z","timestamp":1782132915000},"source":"Crossref","is-referenced-by-count":0,"title":["Aging promotes inflammation and steatosis in alcohol-associated liver disease in mice"],"prefix":"10.64898","author":[{"ORCID":"https:\/\/orcid.org\/0009-0008-9400-7233","authenticated-orcid":false,"given":"Sha Neisha","family":"Williams","sequence":"first","affiliation":[{"name":"Department of Pharmacology, Toxicology and Therapeutics, University of Kansas Medical Center, Kansas City, Kansas 66160, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaowen","family":"Ma","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Toxicology and Therapeutics, University of Kansas Medical Center, Kansas City, Kansas 66160, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Xiaojuan","family":"Chao","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Toxicology and Therapeutics, University of Kansas Medical Center, Kansas City, Kansas 66160, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Hangfei","family":"Xu","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences; Wayne State University, Detroit, MI 48201, USA"},{"name":"Department of Pharmacology, School of Medicine, Wayne State University, Detroit, MI 48201, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Wanqing","family":"Liu","sequence":"additional","affiliation":[{"name":"Department of Pharmaceutical Sciences, Eugene Applebaum College of Pharmacy and Health Sciences; Wayne State University, Detroit, MI 48201, USA"},{"name":"Department of Pharmacology, School of Medicine, Wayne State University, Detroit, MI 48201, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-5300-2654","authenticated-orcid":false,"given":"Hong-Min","family":"Ni","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Toxicology and Therapeutics, University of Kansas Medical Center, Kansas City, Kansas 66160, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3167-5073","authenticated-orcid":false,"given":"Wen-Xing","family":"Ding","sequence":"additional","affiliation":[{"name":"Department of Pharmacology, Toxicology and Therapeutics, University of Kansas Medical Center, Kansas City, Kansas 66160, USA"},{"name":"Department of Internal Medicine, University of Kansas Medical Center, Kansas City, Kansas 66160, USA"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"54368","reference":[{"key":"2026062310301505000_2026.06.19.730442v1.1","doi-asserted-by":"crossref","unstructured":"Abokyi, S. , G.
