    Abstract: Described is a method for methylation detection in a DNA sample. An isolated genomic DNA sample is treated in a manner capable of distinguishing methylated from unmethy-lated cytosine bases. The pretreated DNA is amplified us-ing at least one oligonucleotide primer, a polymerase and a set of nucleotides of which at least one is labeled with a first type of label. A sequence-specific oligonu-cleotide probe, marked with a second type of label, hy-bridizes to the amplification product and a FRET reaction occurs if a labeled oligonucleotide is present in close proximity in the amplification product. The method deter-mines the level of methylation of a sample by measuring the extent of fluorescence resonance energy transfer (FRET) between the donor and acceptor fluorophore.

    Abstract translation: 描述了DNA样品中甲基化检测的方法。 分离的基因组DNA样品以能够区分甲基化和未甲基化胞嘧啶碱基的方式进行处理。 使用至少一种寡核苷酸引物,聚合酶和一组核苷酸扩增预处理的DNA,其中至少一种核苷酸用第一种标记物标记。 用第二种标记标记的序列特异性寡核苷酸探针与扩增产物杂交,如果扩增产物中存在标记的寡核苷酸,则发生FRET反应。 该方法通过测量供体和受体荧光团之间的荧光共振能量转移(FRET)的程度来确定样品的甲基化水平。

    Abstract: The present invention provides for molecular GSTP1 markers that have novel utility for the analysis of methylation patterns within the promoter region and exons 1 and 2 of the GSTP1 gene, and are further useful in methods to effectively distinguish among benign hyperplasia of the prostate and different grades of prostate cancer. Additionally, the subject molecular GSTP1 markers have novel utility for the precise localization of the zone of origin to provide sensitive, accurate and non-invasive methods for the diagnosis and/or prognosis of prostate cell proliferative disorders. The present invention has novel utility for the detection and differentiation of a cell proliferative disorder of the peripheral zone of the prostate.
