摘要:
A method of cancer diagnosis characterized in that ROBO1 protein is detected. Further, there is disclosed a method of treating diseases attributed to abnormal cell growth, comprising administering an antibody capable of binding to ROBO1, and are disclosed, comprising an antibody capable of binding to ROBO1 as an active ingredient, a pharmaceutical composition, cytostatic agent and anticancer agent. Still further, there is disclosed a method of inhibiting the growth of ROBO1 expression cells or method of inducing cytotoxicity in ROBO1 expression cells, comprising bringing an antibody capable of binding to ROBO1 into contact with ROBO1 expression cells. Moreover, there is disclosed a method of monitoring the intensification of hepatitis severity, comprising detection of ROBO1 protein.
摘要:
A protein encoded by a gene having a nucleotide sequence represented by any of SEQ ID NOS:1 to 65 or its fragment; an antibody recognizing the same or an antigen-binding fragment thereof; and a polynucleotide having a nucleotide sequence comprising at least 12 consecutive nucleotides in any of the nucleotide sequences represented by SEQ ID NOS:1 to 65 or a nucleotide sequence complementary thereto: The above gene and protein are useful as diagnostics and remedies for cancer.
摘要:
A modified antibody containing at least two H chain V domains and at least two L chain V domains of a monoclonal antibody which transduces a signal into cells by crosslinking a cell surface molecule to thereby serve as an agonist. Because of being usable as a signal transduction agonist, this modified antibody is useful as a preventive and/or a remedy etc. for various diseases such as caner, inflammation, dysendocrinism and blood diseases.
摘要:
A method for isolating a gene encoding a membrane-bound protein characterized by fusing a functional protein with a fused protein per se, differing from the existing TMT method wherein an epitope recognized by an antibody is carried in a fused protein. This method makes it possible to selectively isolate a gene encoding a membrane-bound protein.
摘要:
Antihuman Mpl antibody is obtained and purified. By using a genetic engineering technique, a single chain antibody of the antihuman Mpl antibody is further constructed. This antibody shows a high agonistic activity. This fact indicates that the activity of an antibody can be reinforced by binding two or more heavy chain variable domains to two or more light chain variable domains with the use of a linker to give a single chain polypeptide.
摘要:
A method of screening substances which inhibit the bonding of TAK1 polypeptide to TAB1 polypeptide, characterized by contacting TAK1 polypeptide and a sample with TAB1 polypeptide and detecting or determining the TAK1 polypeptide bonded to the TAB1 polypeptide.
摘要:
It is considered that a method of measuring a transporter activity by using a budding vaculovirus expressing no endogenous transporter on its membrane has a low background and thus enables highly sensitive measurement of the target activity. Using this method, functional changes caused by SNPs in transporters can be measured on substrates over a broader scope. Thus, it is applicable to tailor made therapy programs.
摘要:
A DNA encoding a novel protein SMAP-1, which has a signal sequence, is successfully isolated by screening a cDNA library originating in human fetal hepatocytes with the use of an originally developed TMT method. The expression characteristics and structural characteristics of SMAP-1 suggest that it is a molecule having an important role in vivo .
摘要:
The present invention discloses a method for determining the efficacy of GPC3-targeting drug therapy for cancer in a patient before the start of GPC3-targeting drug therapy or a patient or determining the continuation of GPC3-targeting drug therapy for a patient, including measuring the number of an immunocyte or an expression level of a molecule expressed on the immunocyte in a biological sample isolated from the patient before the start of GPC3-targeting drug therapy and/or the patient treated with the GPC3-targeting drug therapy, wherein when the number of an immunocyte or an expression level of a molecule expressed on the immunocyte is a predetermined value, the efficacy of the GPC3-targeting drug therapy is determined or the continuation of the GPC3-targeting drug therapy is determined. The present invention also discloses a GPC3-targeting drug or a preparation which is to be administered to a patient for which the efficacy of the GPC3-targeting drug therapy has been determined or the continuation of the GPC3-targeting drug therapy has been determined.
摘要:
A reconstituted human anti-HM1.24 antibody comprising: (A) an L chain comprising: (1) a human L chain C region and (2) an L chain V region containing a human L chain FR and an L chain CDR of a mouse anti-HM1.24 monoclonal antibody; and (B) an H chain comprising: (1) a human H chain C region and (2) an H chain V region containing a human H chain FR and an H chain CDR of a mouse anti-HM1.24 monoclonal antibody. Because of mostly originating in the human antibody and the CDR being less antigenic, this reconstituted human antibody has a low antigenicity against man and, therefore, can be expected as therapeutically usable.
