Recent studies have increasingly demonstrated that cellular senescence, estrogen deficiency, and gut microenvironment dysregulation serve as core driving forces in skeletal aging. In this review, we introduce the concept of the Skeletal Aging Triangle, aiming to elucidate the intricate interactions among these three factors and their synergistic effects in the skeletal aging process. We provide a comprehensive overview of the mechanisms that trigger cellular senescence within bone tissue, the molecular pathways by which estrogen maintains bone homeostasis, the remote regulation of bone metabolism by the gut microenvironment, and the interconnections among these processes. A deeper understanding of the Skeletal Aging Triangle offers new perspectives for the prevention and treatment of skeletal aging\u2013related diseases, while also contributing to improved patient quality of life and alleviating the healthcare burden on society.<\/jats:p>","DOI":"10.3389\/fcell.2026.1727398","type":"journal-article","created":{"date-parts":[[2026,3,24]],"date-time":"2026-03-24T16:17:22Z","timestamp":1774369042000},"update-policy":"https:\/\/doi.org\/10.3389\/crossmark-policy","source":"Crossref","is-referenced-by-count":0,"title":["The triangular drivers of bone aging: mechanistic insights and therapeutic targets in cellular senescence, estrogen deficiency, and gut microenvironment dysregulation"],"prefix":"10.3389","volume":"14","author":[{"given":"Zhiwei","family":"Liu","sequence":"first","affiliation":[{"name":"The Second Clinical Medical College, Shanxi Medical University","place":["Taiyuan, Shanxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Yuqian","family":"Peng","sequence":"additional","affiliation":[{"name":"The Second Clinical Medical College, Shanxi Medical University","place":["Taiyuan, Shanxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jinyu","family":"Hou","sequence":"additional","affiliation":[{"name":"The Second Clinical Medical College, Shanxi Medical University","place":["Taiyuan, Shanxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Guodong","family":"Zhang","sequence":"additional","affiliation":[{"name":"The Second Clinical Medical College, Shanxi Medical University","place":["Taiyuan, Shanxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jindong","family":"Wang","sequence":"additional","affiliation":[{"name":"Department of Orthopaedics and Sports Medicine, The Second Hospital of Shanxi Medical University","place":["Taiyuan, Shanxi, China"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1965","published-online":{"date-parts":[[2026,3,24]]},"reference":[{"key":"B1","doi-asserted-by":"publisher","first-page":"4023","DOI":"10.1007\/s00018-013-1317-1","article-title":"The role of estrogen receptor \u03b1 in the regulation of bone and growth plate cartilage","volume":"70","author":"B\u00f6rjesson","year":"2013","journal-title":"Cell.
