In particular, estrogen regulates the proliferation and differentiation of the endometrium and plays an important role in the development of gynecological diseases such as endometrial cancer. Farnesyl diphosphate synthase (FDPS) is a key enzyme involved in the mevalonate pathway, catalyzing the synthesis of farnesyl pyrophosphate (FPP), which plays an essential role in cholesterol biosynthesis and protein prenylation. In this study, we demonstrated using an in vivo mouse model that the expression of FDPS is regulated by estrogen. FDPS expression was specifically elevated during the proestrus stage of the estrous cycle and subsequently decreased. In ovariectomized (OVX) mice, FDPS expression was significantly increased 24 h after estrogen treatment, whereas this response was suppressed by treatment with the estrogen receptor alpha (ER\u03b1) antagonist, ICI 182,780. Although FDPS expression has been reported in various cancers, its role in endometrial cancer remains unclear. Histological and cellular analyses revealed that FDPS is highly expressed in human endometrial cancer tissues and in the endometrial cancer cell line Ishikawa, where it contributes to cell proliferation. These findings suggest that FDPS may play a role in the survival and growth of endometrial cancer cells. This study provides new insights into the potential function of FDPS in the uterus and suggests that targeting FDPS may represent a promising therapeutic strategy for endometrial cancer.<\/jats:p>","DOI":"10.3390\/ijms27031559","type":"journal-article","created":{"date-parts":[[2026,2,5]],"date-time":"2026-02-05T10:35:37Z","timestamp":1770287737000},"page":"1559","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Estrogen-Dependent Regulation of FDPS in the Mouse Uterus and Its Expression in Endometrial Cancer"],"prefix":"10.3390","volume":"27","author":[{"ORCID":"https:\/\/orcid.org\/0009-0002-0662-8715","authenticated-orcid":false,"given":"Yeonju","family":"Suh","sequence":"first","affiliation":[{"name":"Department of Stem Cell and Regenerative Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4037-9222","authenticated-orcid":false,"given":"Byeongseok","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Stem Cell and Regenerative Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0009-0000-0502-1124","authenticated-orcid":false,"given":"Joohee","family":"Kim","sequence":"additional","affiliation":[{"name":"Department of Stem Cell and Regenerative Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Jimin","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Stem Cell and Regenerative Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sangok","family":"Park","sequence":"additional","affiliation":[{"name":"Department of Stem Cell and Regenerative Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1952-263X","authenticated-orcid":false,"given":"Soohyung","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Stem Cell and Regenerative Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Man Ryul","family":"Lee","sequence":"additional","affiliation":[{"name":"Major in Stem Cell and Regenerative Biotechnology, School of Advanced Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"},{"name":"The Institute of Advanced Regenerative Sciences, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-6436-8918","authenticated-orcid":false,"given":"Hoi Chang","family":"Lee","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, Feinberg School of Medicine, Northwestern University, Chicago, IL 60611, USA"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3862-4105","authenticated-orcid":false,"given":"Youngsok","family":"Choi","sequence":"additional","affiliation":[{"name":"Department of Stem Cell and Regenerative Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"},{"name":"Major in Stem Cell and Regenerative Biotechnology, School of Advanced Biotechnology, Konkuk University, Seoul 05029, Republic of Korea"},{"name":"The Institute of Advanced Regenerative Sciences, Konkuk University, Seoul 05029, Republic of Korea"}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"1968","published-online":{"date-parts":[[2026,2,5]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"225","DOI":"10.5483\/BMBRep.2018.51.5.045","article-title":"Role of estrogen and RAS signaling in repeated implantation failure","volume":"51","author":"Hong","year":"2018","journal-title":"BMB Rep."},{"key":"ref_2","first-page":"4","article-title":"Molecular mechanism of estrogen-estrogen receptor signaling","volume":"16","author":"Ayaz","year":"2016","journal-title":"Reprod.
