  • Patent number: 8735135
    Abstract: Disclosed is a means for improving the poor conversion efficiency in a conventional bioconversion system using a transformant which is given by introducing a gene originated from xerogenic organisms. A transformant is prepared by using a host which is defective in a gene encoding a multidrug efflux protein and introducing a gene originated from xerogenic organisms. Use of the transformant results in much effective microbial conversion of a hydrophobic or amphipathic substrate compound into a desired compound. In case, an Escherichia coli is used as the host, the gene encoding a multidrug efflux protein to be defective may be tolC, acrA, acrB and the like.

  • Patent number: 8637084
    Abstract: It is an object of the present invention to provide a novel method for decreasing the number of clinical cases for which trastuzumab administration is ineffective. The present invention provides a method for treating a living individual with epithelial cancer comprising: step (a) of selectively reducing KLRG1-positive immunocytes in the peripheral blood of a living individual with epithelial cancer ex vivo, which is positive for a cancer-specific membrane antigen expressed in epithelial cancer cells and positive for a KLRG1 ligand; and step (b) of administering, to the living individual, a therapeutic agent for cancer comprising an antibody reacting with the cancer-specific membrane antigen expressed in epithelial cancer cells and having antibody-dependent cell cytotoxicity.

  • Patent number: 8460915
    Abstract: Disclosed is a means for improving the poor conversion efficiency in a bioconversion system using an Escherichia coli cell having a bacterium-originated cytochrome P-450 gene integrated therein. A recombinant Escherichia coli cell is produced by introducing aciB and aciC which encode a gene for the electron transport system originated from the Acinetobacter sp. OC4 strain into an Escherichia coli cell, and adding a polynucleotide encoding an N-terminal sequence composed of 48 amino acid residues of AciA and the like to the 5?-terminus of a bacterium-originated cytochrome P-450 gene, wherein AciA is an alkane-oxidative cytochrome P-450 originated from the Acinetobacter sp. OC4 strain. Use of the recombinant Escherichia coli cell results in much effective microbial conversion of a hydrophobic or amphipathic substrate compound into a desired compound.

  • Patent number: 8093362
    Abstract: An antibody which binds to a polypeptide encoded by human PERP (p53 apoptosis effector related to PMP-22) gene which is considered to be related to incidence of cancer or the like is desired. The present invention provides a gene recombinant antibody which has no consensus sequence of an N-linked sugar chain in a variable region, specifically recognizes three-dimensional structure of an extracellular region of a polypeptide encoded by the PERP gene and binds to the extracellular region. The antibody is useful for treatment of various diseases expressing a polypeptide encoded by the PERP gene.

  • Patent number: 8093361
    Abstract: The present invention provides an antibody which specifically recognizes three-dimensional structure of an extracellular region of a polypeptide encoded by PERP (p53 apoptosis effector related to PMP-22) gene and binds to the extracellular region. The antibody of the present invention is useful for treatment of various diseases which highly expresses a polypeptide encoded by the PERP gene. Also, a polypeptide encoded by the PERP gene or a cell expressing the polypeptide can be specifically detected by an immunological method using the antibody, so that the antibody is useful for diagnosis of various diseases related to PERP.

  • Publication number: 20110150869
    Abstract: The present inventors discovered that neural invasion is suppressed by inhibiting IL-6 in a model for neural invasion of pancreatic cancer, and completed the present invention. The present inventors also demonstrated that: an IL-6 receptor is expressed in cells of human pancreatic cancer cell lines; and IL-6 enhances the chemotactic and migratory activities and intracellular signaling of pancreatic cancer cells; and thus pancreatic cancer can be treated by inhibiting IL-6. Furthermore, the present inventors found that neural invasion of human pancreatic cancer can be suppressed, from the results of administering IL-6 inhibitors to neural invasion model mice.
