Interestingly, our previous studies have implied that exosomal noncoding RNA might serve as promising indicators in multiple diseases.[30, 35, 36] In this study, analysis of the exoRBase database[37, 38] and our data showed that lncRNA BCCE4 was enriched in exosomes from bladder cancer cells, plasma and tissues. The gene discussed is EMSLR; the disease is urinary bladder cancer.
