Abstract
We developed a specific hybridization assay for direct detection of long non-coding RNA urothelial carcinoma associated-1 (lncRNA-UCA1). Total RNA was extracted from urine pellet samples (bladder carcinoma patients and controls). Then, we compared the developed nanoassay with quantitative real time polymerase chain reaction (qRT-PCR) results in detection of urine UCA1 in bladder cancer and control samples. The sensitivity and the specificity of UCA1 nanoassay were 92.1% and 93.3%, respectively. The concordance of the two methods was 98%. Interestingly, all bilharzial benign cases showed negative lncRNA-UCA1 using both methods. UCA1-nanoassay is a valid test for direct detection of urine UCA1 for bladder cancer detection.
