This study develops and utilizes in\u00a0vitro 2D and 3D cell models to evaluate the estrogenic and antiestrogenic properties of compounds. Human breast cancer cell lines T47D and MCF7, stably transfected with a luciferase reporter gene (ERE\u2010LUC), were first compared in 2D. Due to the significantly higher sensitivity and responsiveness observed in the T47D line during preliminary 2D screenings, this cell line was exclusively selected for the development of the 3D spheroid model. Cells were treated with 17\n                    <jats:italic>\u03b2<\/jats:italic>\n                    \u2010estradiol (E2), BPA, and Fulvestrant (FUL) to assess cell viability and luciferase activity. In 2D models, T47D ERE\u2010LUC cells showed higher responsiveness than MCF7 ERE\u2010LUC, which failed to show significant luciferase induction with E2. In the 3D T47D model, cells exhibited significant and robust changes in luciferase activity in response to E2 and BPA, highlighting the enhanced fidelity of 3D cultures in replicating tissue conditions compared to their 2D counterparts. The study highlights the effectiveness of 3D models over 2D in evaluating estrogenic activity. Specifically, the 3D T47D ERE\u2010LUC system serves as a superior, sensitive, and reliable platform for screening EDCs, offering benefits in cost, data speed, and reduced in\u00a0vivo reliance.\n                  <\/jats:p>","DOI":"10.1002\/jat.70168","type":"journal-article","created":{"date-parts":[[2026,3,14]],"date-time":"2026-03-14T02:34:21Z","timestamp":1773455661000},"page":"3424-3436","update-policy":"https:\/\/doi.org\/10.1002\/crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Screening of Estrogenic and Antiestrogenic Effects of Estradiol, Bisphenol A, and Fulvestrant Using 2D and 3D Breast Cancer Cell Systems With a Luciferase Reporter Gene Assay"],"prefix":"10.1002","volume":"46","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-0708-4687","authenticated-orcid":false,"given":"Valentina","family":"Monteleone","sequence":"first","affiliation":[{"name":"Istituto Zooprofilattico Sperimentale del Lazio e della Toscana \u201cM.
