  • Publication number: 20040048279
    Abstract: The present invention concerns a method for toxicological diagnosis. A DNA sample is taken from an organism or a cell culture, which has previously been subjected to a specific substance that is to be investigated for its toxicological effect. The DNA contained in this sample is chemically pretreated and the base sequence of a part of the modified DNA is determined. A methylation state characteristic for the sample or a characteristic methylation pattern is concluded from this. The effect of a substance on the organism or the cell culture is concluded by comparison with data of the methylation states of other samples and/or compared with other substances from a toxicological point of view.

  • Patent number: 6653070
    Abstract: A genomic analysis process is disclosed, in particular for analysing and localising hereditary properties in the genome. This process has applications in a large number of fields, in particular in medicine, agriculture, forensic medicine and fundamental research. This genomic analysis process is characterised in that the amplification products of microsatellites form genomic DNA samples are immobilised. The genomic DNA samples are separated on defined positions of the matrix, before or after being amplified into individual microsatellite markers, the individual positions are evaporated in a mass spectrometer and their molecular weight is determined.

  • Publication number: 20030157510
    Abstract: Described is a method for detecting 5-methylcytosine in genomic DNA samples. First, a genomic DNA from a DNA sample is chemically converted with a reagent, 5-methylcytosine and cytosine reacting differently, and the pretreated DNA is subsequently amplified using a polymerase and at least one primer. In the next step, the amplified genomic DNA is hybridized to at least one oligonucleotide, forming a duplex, and said oligonucleotide is elongated by at least one nucleotide, the nucleotide carrying a detectable label, and the elongation depending on the methylation status of the specific cytosine in the genomic DNA sample. In the next step, the elongated oligonucleotides are analyzed for the presence of the label.

First, a genomic DNA from a DNA sample is chemically converted with a reagent, 5-methylcytosine and cytosine reacting differently, and the pretreated DNA is subsequently amplified using a polymerase and at least one primer. In the next step, the amplified genomic DNA is hybridized to at least two oligonucleotides, the latter being joined by inserting at least one oligonucleotide. In the ligation product, one nucleotide carries a detectable label, and the elongation depends on the methylation status of the specific cytosine in the genomic DNA sample.

  • Publication number: 20030082600
    Abstract: The present invention concerns a method for the detection of cytosine methylation in DNA samples, wherein the following steps are conducted: (a) a genomic DNA sample, which comprises the DNA to be investigated and background DNA, is chemically treated in such a way that all of the unmethylated cytosine bases are converted to uracil, whereas the 5-methylcytosine bases remain unchanged; (b) the chemically treated DNA sample is amplified with the use of at least 1 primer oligonucleotide as well as a polymerase, whereby the DNA to be investigated is preferred as the template over the background DNA, and (c) the amplified products are analyzed and the methylation status in the DNA to be investigated is concluded from the presence of an amplified product and/or from the analysis of additional positions.

  • Patent number: 6214556
    Abstract: Method for characterizing, classifying and differentiating tissues and cell types, for predicting the behavior of tissues and groups of cells, and for identifying genes with changed expression. The method involves obtaining genomic DNA from a tissue sample, the genomic DNA subsequently being subjected to shearing, cleaved by means of a restriction endonuclease or not treated by either one of these methods. The base cytosine, but not 5-methylcytosine, from the thus-obtained genomic DNA is then converted into uracil by treatment with a bisulfite solution. Fractions of the thus-treated genomic DNA are then amplified using either very short or degenerated oligonucleotides or oligonuclcotides which are complementary to adaptor oligonucleotides that have been ligated to the ends of the cleaved DNA.
