Moreover, microRNAs (miRNAs) are emerging as key regulators of cardiovascular pathology and potential circulating biomarkers. We performed high-throughput miRNA profiling in calcified aortic valve tissue and matched patient serum samples using an array that included 98 human miRNAs. Expression data were log10-transformed and filtered to identify biologically relevant miRNAs. Shared miRNAs between tissue and serum were further validated by quantitative real-time polymerase chain reaction (qRT-PCR) in patients and healthy controls. Of the 49 actively expressed miRNAs, 18 were shared between valve tissue and serum. Thus, qRT-PCR validation revealed significant downregulation of miR-17-5p and miR-29a-3p in CAVD patient serum compared to controls. These results indicate that disease-associated miRNA alterations in calcified valves are mirrored in circulation. miR-17-5p and miR-29a-3p represent promising circulating biomarkers for CAVD, reflecting underlying pathological remodeling and extracellular matrix dysregulation. Our findings provide a framework for non-invasive monitoring of valve calcification and highlight miRNA-mediated pathways as potential therapeutic targets.<\/jats:p>","DOI":"10.3390\/ijms262210813","type":"journal-article","created":{"date-parts":[[2025,11,7]],"date-time":"2025-11-07T09:14:45Z","timestamp":1762506885000},"page":"10813","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":3,"title":["Molecular Network Analysis of Circulating microRNAs Highlights miR-17-5p and miR-29a-3p as Potential Biomarkers of Aortic Valve Calcification"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0001-5965-6571","authenticated-orcid":false,"given":"Antonella","family":"Galeone","sequence":"first","affiliation":[{"name":"Department of Surgery, Dentistry, Pediatrics and Gynecology, Division of Cardiac Surgery, University of Verona, 37126 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-4610-1168","authenticated-orcid":false,"given":"Arianna","family":"Minoia","sequence":"additional","affiliation":[{"name":"Department of Engineering for the Innovation Medicine, University of Verona, 37100 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-7163-6194","authenticated-orcid":false,"given":"Michele","family":"Braggio","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, 37100 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-4315-0282","authenticated-orcid":false,"given":"Mattia","family":"Cominacini","sequence":"additional","affiliation":[{"name":"Department of Engineering for the Innovation Medicine, University of Verona, 37100 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-7360-1195","authenticated-orcid":false,"given":"Maria Grazia","family":"Romanelli","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, 37100 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-3263-6671","authenticated-orcid":false,"given":"Luca","family":"Dalle Carbonare","sequence":"additional","affiliation":[{"name":"Department of Engineering for the Innovation Medicine, University of Verona, 37100 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0001-5371-5761","authenticated-orcid":false,"given":"Giuseppe","family":"Faggian","sequence":"additional","affiliation":[{"name":"Department of Surgery, Dentistry, Pediatrics and Gynecology, Division of Cardiac Surgery, University of Verona, 37126 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-0931-018X","authenticated-orcid":false,"given":"Giovanni Battista","family":"Luciani","sequence":"additional","affiliation":[{"name":"Department of Surgery, Dentistry, Pediatrics and Gynecology, Division of Cardiac Surgery, University of Verona, 37126 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]},{"ORCID":"https:\/\/orcid.org\/0000-0003-1166-8033","authenticated-orcid":false,"given":"Maria Teresa","family":"Valenti","sequence":"additional","affiliation":[{"name":"Department of Neurosciences, Biomedicine and Movement Sciences, University of Verona, 37100 Verona, Italy"}],"role":[{"vocabulary":"crossref","role":"author"}]}],"member":"1968","published-online":{"date-parts":[[2025,11,7]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","first-page":"546","DOI":"10.1038\/s41569-023-00845-7","article-title":"Calcific aortic valve disease: Mechanisms, prevention and treatment","volume":"20","author":"Moncla","year":"2023","journal-title":"Nat.
