In this study, using a co‐culture model, we found that the adipocyte‐EC cell interaction promoted SIRT1 signaling in vitro and in vivo xenograft mice models. Furthermore, immunostaining of SIRT1 protein showed significantly higher expression of SIRT1 in endometrial cancer patients than in normal endometria. RNA sequencing analysis revealed <jats:italic>HMMR</jats:italic> (hyaluronan‐mediated motility receptor), an oncogene, as a downstream effector of <jats:italic>SIRT1</jats:italic> in adipocyte‐associated EC. Transient knockdown and chromatin immunoprecipitation assays showed that SIRT1 inhibition impedes transcription of the <jats:italic>HMMR</jats:italic> gene via <jats:italic>FOXM1</jats:italic>, and reduced expression of HMMR in co‐cultured EC cells blocks AURKA activation via TPX2, leading to cell cycle arrest. This is the first study to report the positive correlation between SIRT1 and HMMR in EC patient tumors and might be used as a potential biomarker in EC. Notably, SIRT1 regulates HMMR expression in a FOXM1‐dependent manner, and interfering with SIRT1 may provide a promising strategy for the management of endometrial cancer.","PeriodicalId":19003,"journal":{"name":"Molecular Carcinogenesis","volume":"39 1","pages":""},"PeriodicalIF":4.6,"publicationDate":"2024-09-10","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142221619","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}
