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:
A protein which inhibits osteoclast differentiation and/or maturation and a method of production of the protein. The protein is produced by human embryonic lung fibroblasts and has molecular weight of about 60 kD and about 120 kD under non-reducing conditions and about 60 kD under reducing conditions on SDS-polyacrylamide gel electrophoresis, respectively.The protein can be isolated and purified from culture medium of the said fibroblasts. Furthermore, the protein can be produced by gene engineering.The present invention includes cDNA for producing the protein by gene engineering, antibodies having specific affinity to the protein or a method for determination of the protein concentration using the antibodies.
摘要:
A complex comprising at least one substance selected from the group consisting of an osteoclastogenesis inhibitory factor, an analogue thereof and a variant thereof, which is bound to at least one substance selected from the group consisting of a polysaccharide and a polysaccharide derivative. The complex has a prolonged retention in the bloodstream after administration, making it useful in the treatment and prophylaxis of bone metabolic diseases.
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.
