Circulating miRNAs are correlated with tumor progression in prostate cancer
Open accessAbstract
Circulating miRNAs have recently been indicated as practicable and promising biomarkers for noninvasive diagnosis in various tumor entities. However, cell‐free miRNAs have not been found to correlate with clinicopathological variables in epithelial carcinomas. To learn more about the potential clinical relevance of circulating miRNAs in prostate cancer, we screened 667 miRNAs in serum samples from patients with metastatic (n= 7) and localized prostate cancer (n= 14). Various miRNAs were highly abundant in the sera of patients with metastatic disease, and five upregulated miRNAs (miRNA‐375, miRNA‐9*, miRNA‐141, miRNA‐200b and miRNA‐516a‐3p) were selected for further validation. In the first validation study (n= 45), selected miRNAs were analyzed in a prospectively collected serum set taken from different prostate cancer risk groups. Most of the selected miRNAs were significantly correlated with adverse risk factors when different clinicopathological variables were analyzed. Circulating miRNA‐375 and miRNA‐141 turned out to be the most pronounced markers for high‐risk tumors. Their levels also correlated with high Gleason score or lymph‐node positive status in a second independent validation study (n= 71). In addition, the expression levels of miRNA‐375 and miRNA‐141 were monitored in 72 prostate tissue samples (36 tumor vs. 36 benign). Both miRNAs were highly expressed in all samples and significantly upregulated in the tumors compared to normal tissues. Overall, our observations suggest that miRNA‐375 and miRNA‐141 expression is enhanced in prostate cancer specimens and their release into the blood is further associated with advanced cancer disease.

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
