  • Publication number: 20210246515
    Abstract: The present invention relates to methods for diagnosing prostate cancer and especially diagnosing LG, HG, PrCa Met and CRPC. Specifically, the present invention relates to methods for in vitro diagnosing prostate cancer in a human individual comprising: 1) determining the expression of one or more genes chosen from the group consisting of ACSM1, ALDH3B2, CGREF1, COMP, C19orf48, DLX1, GLYATL1, MS4A8B, NKAIN1, PPFIA2, PTPRT, TDRD1 and/or UGT2B15; and 2) establishing up regulation of expression of said one or more genes as compared to expression of the respective one or more genes in a sample from an individual without prostate cancer thereby providing said diagnosis of prostate cancer.

  • Publication number: 20200392588
    Abstract: Described herein are method, compositions and kits for prognosis of prostate cancer. The methods include determining the ratio of PCA3 and of a prostate-specific marker expression in a urine sample and correlating the value of the PCA3/prostate-specific marker ratio with the aggressiveness and mortality risk of prostate cancer in the subject. The method for prognosing prostate cancer in a sample of a patient includes assessing the amount of a prostate cancer specific PCA3 mRNA and the amount of prostate-specific marker in the sample; determining a ratio value of this amount of prostate cancer specific PCA3 mRNA over the amount of prostate-specific marker; comparing the ratio value to at least one predetermined cut-off value, wherein a ratio value above the predetermined cut-off value is indicative of a higher risk of mortality of prostate cancer as compared to a ratio value below the predetermined cut-off value.

  • Publication number: 20120309006
    Abstract: The invention relates to a method to diagnose prostate cancer by detecting a PCA3 sequence. In one embodiment the method and kit enables amplification of PCA3 RNA through an exon-exon junction of a spliced PCA3 mRNA, and methods and kits to detect an amplified PCA3 RNA, using a probe which spans the amplified exon-exon junction. The methods and kits can detect a PCA3 RNA lacking one intron or more. Also provided are methods of detecting PCA3 RNA expressed in non-prostate tissue or cells of the urinary tract, which comprises PCA3 intron 3. In addition, methods are provided to determine whether a sample from a subject contains or lacks prostate cells, by performing a hybridization and/or amplification reaction on RNA from the sample to detect the presence or level of PCA3 RNA that lacks at least one intron and distinguishing a prostate cell from a non-prostate cell.
