Pregnant mice received subcutaneous DES (0.02, 0.5, 25 µg/kg/day) from gestational day 9 to 17 to assess offspring gubernaculum testis development. Immunofluorescence, immunohistochemistry and western blot were used to detect proliferation (BrdU, Ki-67, PCNA), apoptosis (caspase-3, Bax, Bcl-2), AMPK/p-AMPK, and oxidative stress (gp91phox, p47phox) markers in gubernaculum testis tissues. Primary gubernaculum testis cells were cultured and divided into control, DES (low/medium/high), AMPK inhibitor (Compound C), and ROS scavenger (NAC) intervention groups. CCK-8, BrdU, TUNEL, flow cytometry, and DHE staining were used to detect cell proliferation, apoptosis, cycle and intracellular ROS. Western blot analyzed related protein and AMPK/p-AMPK expression. DES increased mouse stillbirth rate in a dose-dependent manner ( P < 0.05 for medium/high doses), impaired gubernaculum testis development and inhibited testicular descent. DES suppressed proliferation markers but upregulated apoptosis and oxidative stress markers in gubernaculum testis tissues. In vitro, DES elevated intracellular ROS, induced G 1 /S phase arrest and apoptosis, and inhibited proliferation. DES also downregulated p-AMPK; Compound C further exacerbated oxidative stress, while NAC reversed DES-induced oxidative stress and restored AMPK phosphorylation, indicating a bidirectional regulation between AMPK and oxidative stress. DES inhibits the AMPK pathway, relieving its negative regulation of NADPH oxidase and causing excessive ROS production and oxidative stress; accumulated oxidative stress feedback inhibits AMPK phosphorylation, forming a vicious cycle that ultimately leads to gubernacular cell injury.","PeriodicalId":11949,"journal":{"name":"European Journal of Medical Research","volume":"31 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2026-05-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"148672208","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
