摘要:
The present invention relates to a novel protein which binds to Osteoclastogenesis Inhibitory Factor (OCIF-binding molecule; OBM), a process for preparing the same, DNA encoding said protein, a protein having an amino acid sequence encoded by this DNA, a method for producing said protein by genetic engineering technique, and a pharmaceutical composition containing said protein. In addition, screening methods for a substance for controlling expression of said protein using said protein and the DNA, a substance which inhibits or modulates the biological activity of said protein, or a receptor which transmits the action of said protein through binding to said protein, the substance obtained by the screening methods, and a pharmaceutical composition which contains this substance are disclosed. An antibody for said protein, a process for preparing the same, a measuring method of said protein using the antibody, and a medicine comprising the antibody are also disclosed.
摘要:
A protein is provided derived from human fibroblast having an N-terminal amino acid sequence represented by SEQ ID NOS: 1 and 2, having a molecular weight of approximately 15kD under reducing and non-reducing conditions by (dosium dodecyl sulfate-polyacrylamide gel electrophoresis), and having an activity to stimulate growth of osteoblast. The protein is produced by gene engineering procedures, contains the amino acid sequence represented by SEQ ID NO: 9 and has osteoblast growth activity. Also provided is a method for preparing the protein by culturing human fibroblast and treating the conditioned medium for purification. The protein is utilized for the treatment of diseases characterized by decreased bone mass such as osteoporosis or is utilized as an antigen for immunological diagnosis of diseases.

摘要:
Modified TCF in which one or more amino-acid residues of the wild type TCF responsible for glycosylation are substituted or deleted so that at least one N-linked oligosaccharide chain is removed. The modified TCFs have a longer biological half-lives without loss of their biological activities. The modified TCFs are therapeutically important as agents for liver diseases or as anti-cancer drugs.
摘要:
The present invention relates to a TCF mutant having a novel amino acid sequence which is obtained by mutagenesis of one or more amino acid between N-terminus and the first kringle of the amino acid sequence of native TCF and has lowered affinity to heparin and/or elevated biological activity. The present TCF mutant is prepared by gene manipulation of TCF. The TCF mutants of the present invention have proliferative activity and/or growth stimulative activity in hepatocyte and beneficial as a therapeutic agent for various hepatic diseases and an antitumor agent.
摘要:
This invention relates to a DNA coding for a protein that specifically binds to the enhancer of the .alpha.-fetoprotein gene and that promotes transcription of that .alpha.-fetoprotein gene. This DNA is useful, by applying recombinant DNA technology, for the construction of highly efficient gene expression system for the production of proteins having physiological activities in animal cells.
摘要:
Plasmids containing DNA encoding the amino acid sequence of a novel glycoprotein (TCF-II) derived from human fibroblasts, transformed cells with the plasmids and production method of rTCF-II using the transformed cells. rTCF-II can be used as a hepatocyte growth factor or a tumor cytotoxic factor.
摘要:
A novel bone-pathobolism treating agent is provided. A bone-pathobolism treating agent comprising at least one substance selected from the group consisting of osteoclastogenesis inhibitory factor (OCIF), its homologs, and its variants, and a polysaccharide or its derivatives. As the polysaccharide or its derivatives, heparin, dextran sulfate and the like can be used. A bone-pathobolism treating agent is provided which has excellent therapeutic effect on bone-pathobolism such as osteoporosis, hypercalcemia, or chronic articular rheumatism and persistance of the activity. The agent is useful as a medicine.
