Provided is a substance capable of effectively suppressing cancer metastasis or a pharmaceutical composition that effectively acts on an inflammatory disease. The pharmaceutical composition is a pharmaceutical composition containing, as an active ingredient, an antibody or an antibody fragment thereof having antigen-binding activity for an S100A8/A9 heterodimer, and blocks interaction between S100A8/A9 and a group of receptors therefor, to thereby strongly suppress cancer metastasis both in vitro and in vivo, or alleviate inflammation. That is, the anti-S100A8/A9 antibody or the antibody fragment thereof can strongly suppress cancer metastasis or alleviate inflammation, by virtue of its blocking action on the interaction between S100A8/A9 and the group of receptors therefor.

Anti-S100A8/A9 antibody and use thereof

The present invention provides a neutrophil activation regulator comprising a histidine-rich glycoprotein (HRG) for the treatment of systemic inflammatory response syndrome (SIRS), diseases caused by neutrophil activation and/or inflammatory diseases accompanied by neutrophil activation in a subject in need thereof. Further, the present invention provides methods for predicting the severity of systemic inflammatory response syndrome (SIRS), diseases caused by neutrophil activation and/or inflammatory diseases accompanied by neutrophil activation in a subject in need thereof, and methods for predicting the survival of a subject with systemic inflammatory response syndrome (SIRS), diseases caused by neutrophil activation and/or inflammatory diseases accompanied by neutrophil activation, that comprise determining the blood level of histidine-rich glycoprotein in the subject.

Therapeutic agent, method of treatment and method for predicting the severity of systemic inflammatory response syndrome (SIRS), diseases caused or accompanied by neutrophil activation

The present invention provides a therapeutic agent, a treatment method and an inspection method for diseases caused by activation of neutrophils. More specifically, the invention relates to a neutrophil activation regulator which comprising a histidine-rich glycoprotein (HRG) as an active ingredient, and provides a therapeutic agent for diseases caused by neutrophil activation comprising the neutrophil activation regulator, a treatment method for diseases caused by neutrophil activation, and further an inspection method for diseases caused by neutrophil activation. The present invention is based on the neutrophil activation regulator including the HRG as an active ingredient. The present invention extends to the depressant agent for neutrophil-vascular endothelial cell interaction including the HRG of the present invention as an active ingredient, the treatment method for diseases caused by neutrophil activation and/or inflammatory diseases accompanied by neutrophil activation. The present invention also extends to the inspection method for inflammatory diseases accompanied by neutrophil activation by measuring the blood HRG level.

Therapeutic agent, treatment method and inspection method for diseases caused by activation of neutrophils

An object of the present invention is to provide a method for increasing the expression of foreign genes, in particular, using a promoter, an enhancer, and the like, and an expression cassette containing a promoter, an enhancer, and the like, by which gene expression can be increased. The purpose is achieved with the use of the gene expression cassette comprising a DNA construct containing a gene to be expressed and a poly A addition sequence that are located downstream of a 1promoter, and further comprising an enhancer or a 2promoter ligated downstream of the DNA construct.

System for increasing gene expression and vector comprising the system

This invention provides an inducer of apoptosis in cancer cells comprising a fragment of the REIC/Dkk-3 gene and a cancer therapeutic agent comprising the same. This invention also provides a polynucleotide fragment encoding the REIC/Dkk-3 protein (a) or (b), which encodes a polypeptide having apoptosis activity: (a) a polynucleotide encoding a polypeptide comprising an amino acid sequence of amino acid 1 to any of amino acids 39 to 78 of the amino acid sequence of the REIC/Dkk-3 protein as shown in SEQ ID NO: 2; or (b) a polynucleotide encoding a polypeptide comprising an amino acid sequence derived from the amino acid sequence of amino acid 1 to any of amino acids 39 to 78 of the amino acid sequence of the REIC/Dkk-3 protein as shown in SEQ ID NO: 2 by substitution, deletion, or addition of 1 or several amino acids and having apoptosis activity.

Direct administration of REIC/Dkk-3 to mesothelioma

An objective of the present invention is to provide an adenovirus vector expressing a REIC/Dkk-3 protein at a high level and containing a DNA construct for expression of REIC/Dkk-3 DNA, wherein the DNA construct is prepared by ligating, from the 5' terminal side,

REIC-expressing adenovirus vector

According to the present invention, an apoptosis-inducing agent for prostate cancer comprising REIC/Dkk-3 DNA or an REIC/Dkk-3 protein, and a therapeutic agent for prostate cancer and an agent for inhibiting prostate cancer metastasis that comprise such apoptosis-inducing agent are provided. An apoptosis-inducing agent for prostate cancer, comprising, as an active ingredient, an REIC/Dkk-3 protein (a) or (b) or REIC/Dkk-3 DNA (c) or (d):

Apoptosis-inducing agent for prostate cancer cells

A method for potentiating the antitumor immunity in an animal by administering REIC/Dkk-3, or a therapeutic agent for malignant mesothelioma containing REIC/Dkk-3, or a vector containing the DNA as an active ingredient; wherein the DNA consists of the nucleotide sequence shown in SEQ ID NO: 1; or (b) a DNA hybridizing under stringent conditions to the DNA consisting of a nucleotide sequence complementary to the nucleotide sequence shown in SEQ ID NO: 1 and encoding a protein having apoptosis-inducing activity and interleukin (IL-7) production-accelerating activity in cells.

Therapeutic agent for malignant mesothelioma and immunostimulant

Partial fragment of REIC/Dkk-3 gene and cancer therapeutic agent comprising the same
