  • Patent number: 7172867
    Abstract: Differential expression of genes whose expression is different in the activated eosinophils of atopic dermatitis patients was measured by comparative analysis using a gene chip. As a result, the TR3 and TINUR genes, whose expression is significantly elevated in activated eosinophils, were successfully identified. The present inventors discovered that these genes can be used to test for allergic disease and to screen candidate compounds for therapeutic agents for allergic disease.
    Type: Grant
    Filed: July 1, 2003
    Date of Patent: February 6, 2007
    Assignees: Genox Research, Inc., Japan as Represented by General Director of Agency of National Center for Child Health & Development
    Inventors: Ryoichi Hashida, Shinji Kagaya, Yuji Sugita, Hirohisa Saito
  • Patent number: 7148011
    Abstract: The differential display method was used to search for a gene whose expression level in eosinophils collected from patients with atopic dermatitis differs in the exacerbation stage and in the remission stage. As a result, gene “2090-05” showing a significant increase in expression in eosinophils of patients in the remission stage was isolated. This gene is usable in testing for an allergic disease and screening for a candidate compound for a therapeutic agent therefor an allergic disease.

  • Patent number: 7115373
    Abstract: Genes whose expression differ between that in eosinophils collected from atopic dermatitis patients of the exabartation stage and those of the remission stage were searched via a differential display method. As a result, NOR-1 (MINOR) gene was successfully identified whose expression significantly increased in eosinophils of patients in the remission stage, a stage associated with a decrease of eosinophils. The present inventors discovered that the gene can be successfully employed in testing for allergic diseases and screening for candidate compounds for therapeutic agents.
