  • Use of MicroRNAs for Screening and Diagnosis of Prostate Cancer and Benign Prostatic Hyperplasia
    Publication number: 20140309130
    Abstract: Disclosed are microRNA biomarkers and use thereof for screening and diagnosis of prostate cancer and benign prostatic hyperplasia. This invention provides a method for screening for prostate cancer in a subject involving the steps of: (a) assaying the miRNA expression level in a test sample from the subject to be screened for prostate cancer; (b) comparing the assayed miRNA expression level of the subject to the miRNA expression level in a normal sample providing a control relative to the test sample of the subject; and (c) computing the differential expression of the miRNA from the subject, wherein the over-expression of miR-1825 or under the expression of miR-484 is indicative of prostate cancer.
