Collagens and elastic fibers are the most predominant fibrous ECM proteins providing tissue mechanical function through covalent cross-linking, which is mediated by the lysyl oxidase family of enzymes. In this study, the function of lysyl oxidases in maintaining the integrity of the extracellular matrix in the myometrium and its impact on parturition-timing was investigated. Gene and protein expression analyses demonstrate that a subset of the lysyl oxidase family of enzymes are highly induced in pregnant myometrium. Inhibition of the activity of the lysyl oxidase family of enzymes through \u03b2-aminopropionitrile (BAPN) delays parturition in mice, in part because of myometrial dysfunction. In BAPN-treated mice, the expression of genes encoding contraction-associated proteins such as connexin 43, oxytocin receptor, and prostaglandin synthase 2, is significantly reduced in the myometrium compared to the untreated control mice. Proteomic analysis revealed that the composition of the ECM is altered in response to BAPN treatment, which demonstrates that the inhibition of the activity of lysyl oxidases disrupted the integrity of the myometrial ECM. Our findings demonstrate that the lysyl oxidases-mediated ECM function is necessary for the myometrium to transition from a quiescent to a contractile phenotype at term for on-time parturition.<\/jats:p>","DOI":"10.1210\/jendso\/bvaf028","type":"journal-article","created":{"date-parts":[[2025,2,12]],"date-time":"2025-02-12T15:23:37Z","timestamp":1739373817000},"source":"Crossref","is-referenced-by-count":4,"title":["Lysyl Oxidases Are Necessary for Myometrial Contractility and On-time Parturition in Mice"],"prefix":"10.1210","volume":"9","author":[{"given":"Alexis","family":"Ouellette","sequence":"first","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences, University of Vermont Larner College of Medicine , Burlington, VT 05405 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Christina","family":"Do","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences, University of Vermont Larner College of Medicine , Burlington, VT 05405 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Sydney","family":"Cohn-Guthrie","sequence":"additional","affiliation":[{"name":"Department of Biology, Vermont Biomedical Research Network Proteomics Facility, University of Vermont , Burlington, VT 05405 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Ying-Wai","family":"Lam","sequence":"additional","affiliation":[{"name":"Department of Biology, Vermont Biomedical Research Network Proteomics Facility, University of Vermont , Burlington, VT 05405 ,","place":["USA"]},{"name":"Department of Biology, University of Vermont , Burlington, VT 05405 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Mala","family":"Mahendroo","sequence":"additional","affiliation":[{"name":"Department of Obstetrics and Gynecology, University of Texas Southwestern Medical Center , Dallas, TX 75390 ,","place":["USA"]},{"name":"Cecil H. and Ida Green Center for Reproductive Biology Sciences, University of Texas Southwestern Medical Center , Dallas, TX 75390 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3161-6241","authenticated-orcid":false,"given":"Shanmugasundaram","family":"Nallasamy","sequence":"additional","affiliation":[{"name":"Department of Obstetrics, Gynecology, and Reproductive Sciences, University of Vermont Larner College of Medicine , Burlington, VT 05405 ,","place":["USA"]}],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"80","published-online":{"date-parts":[[2025,2,14]]},"reference":[{"issue":"10409","key":"2025040306515346700_bvaf028-B1","doi-asserted-by":"crossref","first-page":"1261","DOI":"10.1016\/S0140-6736(23)00878-4","article-title":"National, regional, and global estimates of preterm birth in 2020, with trends from 2010: a systematic analysis","volume":"402","author":"Ohuma","year":"2023","journal-title":"Lancet"},{"issue":"1","key":"2025040306515346700_bvaf028-B2","first-page":"1","article-title":"Shifts in the distribution of births by gestational age: United States, 2014\u20132022","volume":"73","author":"Martin","year":"2024","journal-title":"Natl Vital Stat Rep"},{"issue":"2","key":"2025040306515346700_bvaf028-B3","first-page":"1","article-title":"Births: final data for 2022","volume":"73","author":"Osterman","year":"2024","journal-title":"Natl Vital Stat Rep"},{"issue":"6198","key":"2025040306515346700_bvaf028-B4","doi-asserted-by":"crossref","first-page":"760","DOI":"10.1126\/science.1251816","article-title":"Preterm labor: one syndrome, many causes","volume":"345","author":"Romero","year":"2014","journal-title":"Science"},{"key":"2025040306515346700_bvaf028-B5","volume-title":"Preterm Birth.
