There is an urgent need to investigate efficacious therapeutic strategies and molecular targets to combat AS. Methods: Apolipoprotein E (ApoE)\u2013\/\u2013 mice fed a high-fat diet were administered glycyrrhetinic acid (GA) to establish the AS intervention model. An enzyme-linked immunosorbent assay (ELISA) was used to detect serum levels of the pro-inflammatory cytokines IL-6 and tumor necrosis factor\u2011\u03b1 (TNF-\u03b1). Concurrently, biochemical analyses measured serum lipid profiles, including low-density lipoprotein cholesterol (LDL-C), high-density lipoprotein cholesterol (HDL-C), triglycerides (TG), and total cholesterol (TC). Total RNA extracted from mouse aortic tissues was subjected to RNA sequencing to identify differentially expressed genes (DEGs), followed by Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses. Cytoscape software, combined with weighted gene co-expression network analysis (WGCNA), was used to filter candidate target genes, and quantitative real-time PCR (qPCR) was conducted to verify the expression levels of hub clock genes. Results: GA markedly suppressed the overproduction of IL-6 and TNF-\u03b1 in AS model mice. Meanwhile, GA reduced serum LDL-C, TG, and TC concentrations and elevated HDL-C levels. RNA-seq-derived DEGs were significantly enriched in biological processes and signaling pathways related to circadian rhythm. Three core clock genes, period circadian clock 1 (Per1), period circadian clock 2 (Per2), and period circadian clock 3 (Per3), were identified as candidate targets. qPCR results validated that GA significantly upregulated the expression of Per1, Per2, and Per3 in aortic tissues. Conclusion: This study preliminarily confirms that GA exerts anti\u2011atherosclerotic effects in ApoE\u2013\/\u2013 mice. Its potential therapeutic mechanism may be associated with circadian rhythm\u2011related signalling involving Per1, Per2, Per3.<\/jats:p>","DOI":"10.31083\/pharmazie55101","type":"journal-article","created":{"date-parts":[[2026,9,29]],"date-time":"2026-09-29T17:05:53Z","timestamp":1790701553000},"source":"Crossref","is-referenced-by-count":0,"title":["GA Eases Atherosclerosis by Regulating Circadian Rhythm"],"prefix":"10.31083","volume":"81","author":[{"given":"Chengxin","family":"Hao","sequence":"first","affiliation":[{"name":"School of Basic Medical Sciences, Baicheng Medical College, 137000 Baicheng, Jilin, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Feifei","family":"Ren","sequence":"additional","affiliation":[{"name":"Nursing Department, Affiliated Hospital, Baicheng Medical College, 137000 Baicheng, Jilin, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Yuting","family":"Guo","sequence":"additional","affiliation":[{"name":"School of Basic Medical Sciences, Baicheng Medical College, 137000 Baicheng, Jilin, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Jing","family":"Ren","sequence":"additional","affiliation":[{"name":"School of Basic Medical Sciences, Baicheng Medical College, 137000 Baicheng, Jilin, China"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-6053-7545","authenticated-orcid":true,"given":"Mingyao","family":"E","sequence":"additional","affiliation":[{"name":"School of Pharmacy, Baicheng Medical College, 137000 Baicheng, Jilin, China"},{"name":"Jilin Ginseng Academy, Changchun University of Chinese Medicine, 130000 Changchun, Jinlin, China"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"16242","published-online":{"date-parts":[[2026,9,18]]},"reference":[{"key":"ref1","doi-asserted-by":"publisher","unstructured":"Fan J, Watanabe T.
