MicroRNAs in urine are not biomarkers of multiple myeloma.

Background: In this study, we aimed to identify microRNA from urine of multiple myeloma patients that could serve as a biomarker for the disease.

Results: Analysis of urine samples was performed using Serum/Plasma Focus PCR MicroRNA Panel (Exiqon) and verified using individual TaqMan miRNA assays for qPCR. We found 20 deregulated microRNA (p < 0.
