Fumihiko Yokoya has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Polypeptides, use thereof and process for producing the same
    Patent number: 7189810
    Abstract: An isolated polypeptide comprises the amino acid sequence of SEQ ID NO: 11, wherein the expression of said polypeptide is significant lower specifically in human livers with hepatitis compared with that in human health livers. The detection of said polypeptide expression in human liver can be used as a diagnosis for human hepatitis.
    Type: Grant
    Filed: December 26, 2002
    Date of Patent: March 13, 2007
    Assignee: Ajinomoto Co., Inc.
    Inventors: Takami Maekawa, Hisao Fukuda, Fumihiko Yokoya, Tomohisa Okutsu, Yoshiyuki Takahara
  • Gene panel participating in liver regeneration
    Publication number: 20060105329
    Abstract: A gene panel comprising a group of genes of which expression levels change in hepatocytes during liver regeneration as compared with those in a normal state is produced by the following steps: (a) the step of measuring expression levels of various genes in hepatocytes of a model animal in a normal state and expression levels of the genes during liver regeneration; (b) the step of comparing the expression levels, respectively; and (c) the step of identifying a group of genes of which expression levels change during liver regeneration.

  • Gene panel participative in hepatic stellate cell activation
    Publication number: 20040161786
    Abstract: A gene panel comprising genes each showing, in hepatic stellate cells, a varied expression level in a hepatic stellate cell activation state compared with a level in a normal state, comprising the steps of:

  • Polypeptides, use thereof and process for producing the same
    Publication number: 20030187185
    Abstract: A polypeptide having a production level specifically lowered in human diseased human livers. This polypeptide provides a novel diagnostic means for hepatitis by determining the production level of the polypeptide or an mRNA encoding the polypeptide in the liver.
