Histologic features diagnostic of LS were the basis of pathologic evaluation. Foci of areas diagnostic for LS or non-LS strictures were chosen for RNA evaluation. In an initial screening analysis, 13 LS urethral strictures and 13 non-LS strictures were profiled via miRNA RT-qPCR arrays for 752 unique miRNA. A validation analysis of 23 additional samples (9 LS and 14 non-LS) was performed for 15 miRNAs. Statistical analyses were performed using SPSS v25. Gene Ontology (GO) analysis was performed using DIANA-mirPath v. 3.0.<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec003\">\n<jats:title>Results<\/jats:title>\n<jats:p>In the screening analysis 143 miRNAs were detected for all samples. 27 were differentially expressed between the groups (false discovery p-value &lt;0.01). 15 of these miRNAs individually demonstrated an area under the curve (AUC)&gt;0.90 for distinguishing between between LS and non-LS strictures. 11-fold upregulation of MiR-155-5p specifically was found in LS vs. non-LS strictures (p&lt;0.001, AUC = 1.0). In the validation analysis, 13 of the 15 miRNAs tested were confirmed to have differential expression (false discovery p-value &lt;0.10).<\/jats:p>\n<\/jats:sec>\n<jats:sec id=\"sec004\">\n<jats:title>Conclusions<\/jats:title>\n<jats:p>To our knowledge this is the first study evaluating miRNA expression profiles in LS and non-LS USD. We identified several miRNAs that are differentially expressed in USD caused by LS vs other etiologies, which could potentially serve as biomarkers of LS USD. The top eight differentially expressed miRNAs have been linked to immune response processes as well as involvement in wound healing, primarily angiogenesis and fibrosis.<\/jats:p>\n<\/jats:sec>","DOI":"10.1371\/journal.pone.0261505","type":"journal-article","created":{"date-parts":[[2021,12,15]],"date-time":"2021-12-15T18:35:35Z","timestamp":1639593335000},"page":"e0261505","update-policy":"https:\/\/doi.org\/10.1371\/journal.pone.corrections_policy","source":"Crossref","is-referenced-by-count":7,"title":["Differential expression of miRNAs involved in biological processes responsible for inflammation and immune response in lichen sclerosus urethral stricture disease"],"prefix":"10.1371","volume":"16","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4022-5741","authenticated-orcid":true,"given":"Harjivan","family":"Kohli","sequence":"first","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Brandon","family":"Childs","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3395-0294","authenticated-orcid":true,"given":"Travis B.","family":"Sullivan","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1003-6616","authenticated-orcid":true,"given":"Artem","family":"Shevtsov","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-3122-2875","authenticated-orcid":true,"given":"Eric","family":"Burks","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Thomas","family":"Kalantzakos","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"given":"Kimberly","family":"Rieger-Christ","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-0755-0094","authenticated-orcid":true,"given":"Alex J.","family":"Vanni","sequence":"additional","affiliation":[],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"340","published-online":{"date-parts":[[2021,12,15]]},"reference":[{"issue":"1","key":"pone.0261505.ref001","doi-asserted-by":"crossref","first-page":"191","DOI":"10.1016\/j.urology.2012.08.062","article-title":"Contemporary urethral stricture characteristics in the developed world","volume":"81","author":"E Palminteri","year":"2013","journal-title":"Urology"},{"issue":"1","key":"pone.0261505.ref002","doi-asserted-by":"crossref","first-page":"1","DOI":"10.1159\/000078794","article-title":"Lichen sclerosus of the male genitalia and urethral stricture diseases","volume":"73","author":"G Barbagli","year":"2004","journal-title":"Urol Int"},{"key":"pone.0261505.ref003","doi-asserted-by":"crossref","DOI":"10.1007\/978-1-4614-7708-2_12","article-title":"Stricture Excision and Primary Anastomosis for Anterior Urethral Strictures","author":"R.
