摘要:
Platelet-derived endothelial cell growth factor (PD-ECGF) is a 45 kDa endothelial cell mitogen that has been purified to homogeneity from human platelets. It does not bind to heparin and does not stimulate the proliferation of fibroblasts, in contrast to other endothelial mitogens of the fibroblast growth factor (FGF) family. PD-ECGF appears to be the only endothelial cell growth factor in human platelets and recent data indicate that it has angiogenic activity in vitro, i.e., the ability to stimulate the formation of new blood vessels and chemotactic activity, in vitro. The present invention provides a homogeneous PD-ECGF in substantially greater yields than available in the past, the primary structure of PD-ECGF, antibodies against PD-ECGF, clones of its cDNA, and variants thereof. The invention also provides a therapeutic preparation of PD-ECGF.
摘要:
The invention describes antagonists for PDGF. The antagonists contain amino acids, and may be monomers or dimers. Especially preferred are dimers which bind the PDGF receptors, but prevent dimerization of the bound receptors. Dimerization is necessary for PDGF effect, hence the antagonistic effect. Also described are nucleic acid sequences for making the antagonists, as well as cell lines transfected with the material.
摘要:
The invention relates to large latent complexes of TGF-.beta.2 and TGF-.beta.3, and methods for isolating these. The complex consists of a dimerized form of TGF-.beta.2 or TGF-.beta.3, the appropriate latency associated peptide, and the latent TGF-.beta.1 binding protein, referred to as LTBP. Also described is a protein which binds to all of TGF-.beta.1, TGF-.beta.2 and TGF-.beta.3, but is immunologically distinct from LTBP, referred to as LTBP-2.
摘要:
DNA encoding two forms of PDGF A-chain polypeptide, the construction of expression vectors for expressing such DNA in yeast and mammalian cells, and the expression of such DNA in yeast and mammalian cells to produce active PDGF A-chain homodimer and active PDGF A-chain/B-chain heterodimer are disclosed.
摘要:
Purified protein known as platelet TGF-.beta.1-BP (transforming growth factor-.beta.1-binding protein) is described. The protein is useful for purposes such as the production of antisera which are useful in identifying complexes containing the binding protein, as well as in formation of labeled probes. Also described are purified DNA which expresses the protein, as well as messenger RNA translated into the protein. The protein contains 16 epidermal growth factors (EGF) like repeats, and 3 repeats not found in other proteins. The DNA for the protein is found to contain consensus sequences for hydroxylation of asparagine/aspartic acid residues, and, in the purified protein beta hydroxylated asparagine residues were found.
摘要:
Disclosed herein are methods to inhibit cleavage of a type I receptor of transforming growth factor beta (TβRI) and reduce cancer cell invasiveness/metastasis, and agents and pharmaceutical compositions for use in these methods. Also disclosed herein are methods for identifying agents that inhibit cleavage of TβRI and methods for diagnosing and/or prognosing cancer based on nuclear localization of a intracellular domain of TβRI, which is a product of TβRI cleavage.
摘要:
A new receptor family has been identified, of activin-like kinases. Novel proteins have activin/TGF-beta-type I receptor functionality, and have consequential diagnostic/therapeutic utility. They may have a serine/threonine kinase domain, a DFKSRN or DLKSKN sequence in subdomain VIB and/or a GTKRYM sequence in subdomain VIII.

This document relates to methods and materials for determining whether or not a horse contains a Grey allele. For example, diagnostic methods such as nucleic acid-based detection methods and materials such as nucleic acid probes and primer pairs that can be used to determine whether or not a horse contains a duplication in intron 6 of STX17 nucleic acid are provided. This document also relates to methods and materials for treating a mammal having or being likely to develop cancer (e.g., benign, malignant, or metastatic cancer). For example, methods and materials for treating cancer in a mammal by administering an agent having the ability to reduce expression of an STX17 polypeptide and/or an NR4A polypeptide (e.g., an NR4A1, NR4A2, or NR4A3 polypeptide) in the mammal are provided.
