  • Patent number: 8129122
    Abstract: A method for objectively predicting possibility of metastasis to a cervical lymph node in an early stage for an individual case diagnosed as an oral cavity cancer, and a diagnosis kit to be used in the prediction are provided. The method includes a step of assaying expression amounts of metastasis prediction genes in which the expression amounts are changed between a metastasis group and a non-metastasis group, with respect to a sample collected from a primary legion of the oral cavity cancer. Further, the method includes a step of predicting the possibility of the metastasis by comparing the expression amounts of the metastasis gene group with the expression amounts of the metastasis prediction genes in a metastasis group and/or a non-metastasis group. Herein, the metastasis prediction gene group includes two genes MSR1 (NM_138716.1) and RET (M31213.1).

  • Patent number: 7678543
    Abstract: A method for amplifying genomic DNA is provided. The method comprises the steps of: (1) incubating a cell-containing agarose solution at a pH of 9 to 12 and a temperature of 45 to 80° C. to produce a genomic DNA-dispersed agarose solution wherein 0.002 to 1 copies/5 microliter of single-stranded genomic DNA is dispersed; (2) solidifying the genomic DNA-dispersed agarose solution to produce a genomic DNA-dispersed agarose gel and neutralizing a pH of the gel; and (3) adding a DNA polymerase with strand displacement activity, primer and dNTP to the genomic DNA-dispersed agarose gel and incubating the gel at a temperature of 0 to 60° C. to amplify the genomic DNA.

  • Publication number: 20070264648
    Abstract: There are provided a DNA oligomer, a genetic marker, and a DNA oligomer set (PCR primer set) and a DNA oligomer (extension primer) for predicting a possibility of onset of a side-effect from radiation therapy for cancer by determining whether a specific base in a DNA sequence is a risk allele or a non-risk allele, and a method for predicting onset of a side-effect from radiation therapy. The DNA oligomer for a prediction of onset of a side-effect from radiation therapy has a DNA sequence of at least 10-241 contiguous bases with a 121st base from a sequence of any one of SEQ ID NOs: 1-173 in the Sequence Listing.
