Recent scientific studies have demonstrated that specific microRNAs regulate cancer cell proliferation by modulating the Wnt\/\u03b2-catenin pathway. To date, no published literature has provided a comprehensive assessment of the interactions between miR-106a-5p and miR-375-3p and components of the Wnt\/\u03b2-catenin pathway in prostate cancer. Therefore, the aim of the present study was to perform a pilot evaluation of the expression of miRNAs 106a-5p and 375-3p, as well as \u03b2-catenin, Fzd8, Wnt5a, and cyclin D1 in prostate adenocarcinoma compared with BPH. The study material consisted of samples collected from 30 patients with prostate cancer and 30 with BPH. Protein expression was analyzed using IHC and qRT-PCR methods, while miRNA levels were quantified by dPCR. Our study results revealed lower immunoreactivity and expression of genes encoding \u03b2-catenin, Fzd8, Wnt5a, and cyclin D1 and significantly higher fluorescence intensity of miRNA 106a-5p and 375-3p with prostate adenocarcinoma compared to BPH. These parallel alterations in miRNA expression and Wnt\/\u03b2-catenin-related components reflect disease-specific expression patterns and warrant further investigation in larger cohorts to determine their potential utility as diagnostic biomarkers in prostate diseases.<\/jats:p>","DOI":"10.3390\/ijms262412073","type":"journal-article","created":{"date-parts":[[2025,12,15]],"date-time":"2025-12-15T15:52:59Z","timestamp":1765813979000},"page":"12073","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":0,"title":["Assessment of miRNA 106a-5p and 375-3p Expression in the Context of the Wnt\/\u03b2-Catenin Pathway\u2014Comparison of Prostate Adenocarcinoma and Benign Prostatic Hyperplasia Tissues"],"prefix":"10.3390","volume":"26","author":[{"ORCID":"https:\/\/orcid.org\/0000-0002-3398-366X","authenticated-orcid":false,"given":"Magdalena","family":"Smerecza\u0144ska","sequence":"first","affiliation":[{"name":"Department of Histology and Cytophysiology, Medical University of Bialystok, Mickiewicza 2C Street, 15-222 Bialystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Natalia","family":"Domian","sequence":"additional","affiliation":[{"name":"Department of Histology and Cytophysiology, Medical University of Bialystok, Mickiewicza 2C Street, 15-222 Bialystok, Poland"}],"role":[{"role":"author","vocabulary":"crossref"}]},{"ORCID":"https:\/\/orcid.org\/0000-0002-1453-8501","authenticated-orcid":false,"given":"Grzegorz","family":"M\u0142ynarczyk","sequence":"additional","affiliation":[{"name":"Department of Urology, Medical University of Bialystok, M.
