  • Patent number: 7615341
    Abstract: An gene was identified as a RA disease susceptibility gene on Human Chromosome 8, the gene coding a protein that has an amino acid sequence shown in SEQ. ID NO. 1 and that has such mutation that glycine is inserted as a 269th amino acid in the sequence. Moreover, it was found that mutation of the gene and the protein relate to onset of RA. Achieved is a method of evaluating with high accuracy the onset or onset possibility of RA by using the mutation.

  • Patent number: 6620593
    Abstract: There is disclosed a method for evaluation of the safety of a chemical compound, which includes the steps of: (a) reacting a chemical compound with recombinant yeast cells expressing, or in other words producing, human cytochrome P450 molecular species P450 1A2, P450 2C9, P450 2E1 and P450 3A4 together with a yeast NADPH-P450 reductase, which may be in the form of a fused enzyme with each of said human cytochrome P450 molecular species, or with the cell free extracts of the yeast cells; and (b) analyzing the resulting metabolite to determine the safety of the compound. According to this method, it can be determined whether a test compound will be converted into a carcinogenic or mutagenic form through the metabolism in the human liver, and whether the test compound or its metabolite has mutagenicity.

  • Patent number: 5821062
    Abstract: An oligonucleotide which can hybridize with a human-derived cytochrome P450IIC18 gene, one of the enzymes participating in the metabolic decomposition of medicines, has a GC content of 40-70%, and comprises 8 to 500 nucleotide units. The use of the oligonucleotide in the recognition or amplification of a DNA having the base sequence of this gene enables the presence or absence of mutation to be readily diagnosed and analyzed before the administration of a medicine. Thus it becomes possible to determine a safe dose of a medicine which has been difficult to use because of the occurrence of individual difference in drug-metabolizing ability and to use also a medicine which takes an active form by the action of this enzyme according to individuals.
