MicroRNA expression profile of primary prostate cancer stem cells as a source of biomarkers and therapeutic targets

ABSTRACT: MicroRNA (miRNA) expression profiles were generated from prostate epithelial sub-populations, enriched from patient-derived benign prostatic hyperplasia (BPH, n=5), Gleason 7 treatment naïve prostate cancer (PCa, n=5) and castration-resistant prostate cancer (CRPC, n=3). Microarray expression was validated in an independent patient cohort (n=10). The analyses show that miRNA expression in epithelial sub-populations (e.g. stem cells) clustered together, irrespective of pathological status. We also discovered concordance between the miRNA expression profiles of unfractioned CRPCs, human embryonic stem cells (SCs), and prostate epithelial SCs (both, benign and malignant). miR-548c-3p was chosen as a candidate miRNA from this group to explore its utility as a CRPC biomarker and/or therapeuti
