  • 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.

  • Publication number: 20090233285
    Abstract: The present invention relates, in general, to prostate cancer. More specifically, the present invention relates to a method to diagnose prostate cancer in a patient by detecting a PCA3 sequence, and more particularly a PCA3 RNA, the PCA3 sequence detected in a sample from the patient being specifically associated with prostate cancer. In a particular embodiment the method and kit enables an amplification of a PCA3 RNA through an exon-exon junction of a spliced PCA3 mRNA. The invention also relates to methods and kits to detect such an amplified PCA3 RNA, using a probe which spans the amplified exon-exon junction. In particular the methods and kits are designed to detect a PCA3 RNA which lacks one intron or more, and in particular case is intron-less. The invention further relates to a method of detecting PCA3 RNA expressed in non-prostate tissue or cells of the urinary tract, that comprises PCA3 intron 3.

The invention also relates to kits containing nucleic acid primers and kits containing nucleic acid primers and nucleic acid probes to diagnose, assess, or prognose a human afflicted with prostate cancer. In particular the methods and kits are designed to detect a PCA3 RNA which lacks one intron or more, and in particular case is intron-less.
