Early detection and accurate prognosis are crucial for effective management. This study delves into the diagnostic and prognostic potential of 28S rRNA-derived fragments (rRFs) in PCa. Total RNA extracted from 89 PCa and 53 benign prostate hyperplasia (BPH) tissue specimens. After 3'-end polyadenylation, we performed reverse transcription to create first-strand cDNA. Using an in-house quantitative real-time PCR (qPCR) assay, we quantified 28S rRF levels. Post-treatment biochemical relapse served as the clinical endpoint event for survival analysis, which we validated internally through bootstrap analysis. Our results revealed downregulated 28S rRF levels in PCa compared to BPH patients. Additionally, we observed a significant positive correlation between 28S rRF levels and higher Gleason scores and tumor stages. Furthermore, PCa patients with elevated 28S rRF expression had a significantly higher risk of post-treatment disease relapse independently of clinicopathological data. In conclusion, our study demonstrates, for the first time, the prognostic value of 28S rRF in prostate adenocarcinoma. Elevated 28S rRF levels independently predict short-term PCa relapse and enhance risk stratification. This establishes 28S rRF as a potential novel molecular marker for PCa prognosis.</style></abstract><accession-num><style face="normal" font="default" size="100%">38203408</style></accession-num><notes><style face="normal" font="default" size="100%">Diamantopoulos, Marios AGeorgoulia, Konstantina KLevis, PanagiotisKotronopoulos, GeorgiosStravodimos, KonstantinosKontos, Christos KAvgeris, MargaritisScorilas, AndreasengSwitzerland2024/01/11 07:42Int J Mol Sci. 2023 Dec 23;25(1):239. doi: 10.3390/ijms25010239.</style></notes><custom2><style face="normal" font="default" size="100%">PMC10779029</style></custom2><auth-address><style face="normal" font="default" size="100%">Department of Biochemistry and Molecular Biology, National and Kapodistrian University of Athens, Panepistimiopolis, 15701 Athens, Greece.First Department of Urology, &quot;Laiko&quot; General Hospital, School of Medicine, National and Kapodistrian University of Athens, 11527 Athens, Greece.Laboratory of Clinical Biochemistry-Molecular Diagnostics, Second Department of Pediatrics, &quot;P. &amp; A.
