Dysregulation of microRNAs and Centromere Protein Genes in Prostate Cancer and Metastatic Progression.
Article in Urology research & practice, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
objectiveAccurate prediction of disease progression and metastatic potential remains a major challenge in prostate cancer management. This study aimed to evaluate the expression profiles of selected microRNAs (miRNAs) and cell cycle-related genes as centromere protein genes (CENPs) in prostate cancer and to explore their potential clinical relevance in distinguishing metastatic disease.
methodsFormalin-fixed paraffin-embedded prostate tissue samples from patients with benign prostatic hyperplasia, localized prostate cancer, and metastatic prostate cancer were analyzed. Quantitative real-time polymerase chain reaction (PCR) (qRTPCR) was used to assess the expression of miRNAs targeted CENPs as well as CENPA, CENPC, HJURP, and AURKB. Expression patterns were further validated in the metastatic prostate cancer cell line PC3. Relative expression levels were calculated using the 2-ΔΔCt (cycle threshold) method.
resultsExpression analysis of selected miRNAs revealed a significant upregulation of hsa-miR-4755-5p in the metastatic PCa (P = .027), despite no significant differences in fold change. Additionally, hsa-miR-5680 showed a significantly higher fold change in the metastatic group compared to controls (P = .034). Although not statistically significant (P > .05), hsa-miR-5688, hsa-miR-20a-5p, and hsa-miR-4500 demonstrated a consistent trend toward downregulation, as indicated by lower ΔΔCt values in both PCa and metastatic groups relative to controls. In PCa cell line CENPA, CENPC,and HJURP expression levels increased over time, whereas AURKB was downregulated.
conclusionThe findings indicate that combined dysregulation of specific microRNAs and centromere-associated genes characterizes metastatic prostate cancer. This molecular signature may provide clinically relevant information for risk stratification and warrants further investigation as a potential adjunct to conventional prognostic markers in prostate cancer.
