  • Publication number: 20240118288
    Abstract: An object of the invention is to provide a comprehensive biomarker for artery lesions, and diabetes mellitus, heart disease, cerebrovascular disorder, cancer, kidney disease, etc., whose onset and progress can be suppressed by health care such as early diagnosis. The inventors have found that the object can be attained by determining the level of an antibody to protein KIAA0513 or a portion of the protein, the antibody being potentially present in a body fluid sample collected from a living body; and acquiring data showing a rise in the antibody level as data showing the presence of an artery lesion or the potential or actual presence of cerebrovascular or cardiovascular disorder, diabetes mellitus, chronic kidney disease, or a solid cancer.

  • Patent number: 11782061
    Abstract: The present inventors have surprisingly found that a deoxyhypusine synthase (DHPS) gene, which was previously reported to correlate with prostate cancer and cervical cancer, is highly responsive to arteriosclerosis or digestive system cancer, whereby the gene can be used as a desired marker for arteriosclerosis or digestive system cancer. The present invention has been accomplished on the basis of this finding. Specifically, the present invention provides a method for determining arteriosclerosis or digestive system cancer, which method includes detecting expression of a deoxyhypusine synthase gene in a test sample (preferably a blood sample), and determining arteriosclerosis or digestive system cancer of a test subject from which the test sample has been obtained, on the basis of an increase in the gene expression as an index.
