Despite its clinical significance, the molecular pathogenesis underlying both BO and OC is not well understood. In recent years, epigenetic dysregulation, particularly aberrant DNA methylation, has emerged as a critical area of investigation, given its potential utility in the identification of diagnostic, prognostic, and therapeutic biomarkers. This review examines the evolving epigenetic landscape of esophageal cancer, including a focus on its origins in BO with a particular emphasis on DNA methylation, the most extensively researched epigenetic mechanism. Key DNA methylation\u2010associated alterations involved in OAC and OSCC initiation and progression are discussed, alongside their potential clinical application as biomarkers for early detection, prognosis, and risk stratification in BO populations. Furthermore, the role of these epigenetically regulated genes in the disruption of Wnt signaling and cell cycle control pathways implicated in esophageal carcinogenesis is explored. The review concludes by outlining future research directions, current challenges, and the promise of epigenetic studies in advancing our understanding of OC pathogenesis and improving patient outcomes.<\/jats:p>","DOI":"10.1002\/gcc.70167","type":"journal-article","created":{"date-parts":[[2026,8,31]],"date-time":"2026-08-31T12:16:45Z","timestamp":1788178605000},"update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Understanding the Epigenetic Landscape of Barrett's Esophagus and Esophageal Cancer: A Review of Current Findings, Caveats and Future Directions"],"prefix":"10.1002","volume":"65","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-8825-108X","authenticated-orcid":false,"given":"Louise","family":"Lawless","sequence":"first","affiliation":[{"name":"Sustainability and Health Research Hub, Greenway Hub, Technological University Dublin  Dublin Ireland"},{"name":"School of Biological, Health and Sports Sciences, Technological University Dublin  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Trevor","family":"Doherty","sequence":"additional","affiliation":[{"name":"School of Biological, Health and Sports Sciences, Technological University Dublin  Dublin Ireland"},{"name":"Research Ireland Centre for Research Training in Machine Learning, Technological University Dublin  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Carla","family":"Surlis","sequence":"additional","affiliation":[{"name":"School of Biological, Health and Sports Sciences, Technological University Dublin  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Niamh","family":"Gilmartin","sequence":"additional","affiliation":[{"name":"Sustainability and Health Research Hub, Greenway Hub, Technological University Dublin  Dublin Ireland"},{"name":"School of Biological, Health and Sports Sciences, Technological University Dublin  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7647-2798","authenticated-orcid":false,"given":"Therese M.","family":"Murphy","sequence":"additional","affiliation":[{"name":"Sustainability and Health Research Hub, Greenway Hub, Technological University Dublin  Dublin Ireland"},{"name":"School of Biological, Health and Sports Sciences, Technological University Dublin  Dublin Ireland"},{"name":"Research Ireland Centre for Research Training in Machine Learning, Technological University Dublin  Dublin Ireland"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"311","published-online":{"date-parts":[[2026,8,31]]},"reference":[{"key":"e_1_2_14_2_1","doi-asserted-by":"publisher","DOI":"10.1007\/s12328\u2010020\u201001237\u2010x"},{"key":"e_1_2_14_3_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.asjsur.2016.10.005"},{"key":"e_1_2_14_4_1","doi-asserted-by":"publisher","DOI":"10.1111\/1759\u20107714.14745"},{"key":"e_1_2_14_5_1","doi-asserted-by":"publisher","DOI":"10.1016\/j.canep.2016.01.013"},{"key":"e_1_2_14_6_1","doi-asserted-by":"publisher","DOI":"10.14740\/wjon1254"},{"issue":"3","key":"e_1_2_14_7_1","first-page":"211","article-title":"Barrett's Esophagus","volume":"115","author":"Bujanda D.
