To date, a variety of transcriptional substances in urinary exosomes have been found to play a role in prostate cancer and are potentially attractive in terms of prostate cancer biomarkers, e.g., PCA3, MALAT1, HOTAIR, miR-1290, and miR-375 are some of the more common markers [10, 15]. The gene discussed is MALAT1; the disease is prostate cancer.
