Also provided is a procedure for producing such polypeptides by recombinant techniques employing, for example, vectors and host cells. Also disclosed are methods for utilizing such polypeptides and modulators thereof for the treatment of diseases, including cancer, immune diseases, infectious diseases, and ischemic diseases.
摘要:
The invention provides FGFR fusion proteins, methods of making them, and methods of using them to treat proliferative disorders, including cancers and disorders of angiogenesis. The FGFR fusion molecules can be made in CHO cells and may comprise deletion mutations in the extracellular domains of the FGFRs which improve their stability. These fusion proteins inhibit the growth and viability of cancer cells in vitro and in vivo. The combination of the relatively high affinity of these receptors for their ligand FGFs and the demonstrated ability of these decoy receptors to inhibit tumor growth is an indication of the clinical value of the compositions and methods provided herein.

摘要:
Aspects of the present invention relate to compositions and methods of reprogramming a somatic cell to give rise to an autologous embryonic stem cell. These methods involve providing a somatic cell of a donor subject, introducing the somatic cell into an embryo of a recipient subject to produce a chimeric embryo, allowing the chimeric embryo to develop further wherein the somatic cell will reprogram, and then selecting an autologous embryonic stem cell that has developed from the somatic cell. The methods and composition of producing pluripotent embryonic stem cells from a donor's own somatic cells invite the possibility of a number of therapeutic applications, including organ transplant and treatment of autoimmune diseases, cancer, and degenerative disorders such as diabetes, Alzheimer's, and Parkinson's.
摘要:
DNA sequences encoding human platelet-derived growth factor receptors (hPDGF-R), and expression constructs comprising sequences which encode a receptor that can be secreted or incorporated into the membrane of a mammalian cell. Peptide fragments with functions equivalent to the wild-type receptor, conferring a PDGF-sensitive mitogenic response on cells lacking the receptor are provided. The constructs can be used for enhancing PDGF response of cells, determining the regions involved in transducing the signal in response to PDGF binding, providing mutated analogs and evaluating drugs for their physiologic activity. Soluble fragments comprising PDGF receptor sequences are also provided, including important intracellular kinase insert sequences which interact with intracellular proteins.

Inhibitors of KIAA0175 are provided that reduce the expression or biological activities of KIAA0175, p53 and/or p21 in a mammalian cell. KIAA0175 inhibitors include anti-sense molecules, ribozymes, antibodies and antibody fragments, proteins and polypeptides as well as small molecules. KIAA0175 inhibitors find use in compositions and methods for decreasing KIAA0175, p53 and/or p21 gene expression as well as methods for increasing the chemo and/or radiosensitivity of mammalian cells, including tumor cells, methods for decreasing the side effects of cancer therapy and methods for treating neoplastic diseases.
摘要:
This invention relates to novel human polynucleotides and variants thereof, their encoded polypeptides and variants thereof, to genes corresponding to these polynucleotides and to proteins expressed by the genes. The invention also relates to diagnostic and therapeutic agents employing such novel human polynucleotides, their corresponding genes or gene products, e.g., these genes and proteins, including probes, antisense constructs, and antibodies.
摘要:
A DNA sequence encoding human platelet-derived growth factor receptor (hPDGF-R) has now been isolated and sequenced. An expression construct comprising the sequence encodes a receptor that can be secreted or incorporated into the membrane of a mammalian cell. The incorporated receptor is functionally equivalent to the wild-type receptor, conferring a PDGF-sensitive mitogenic response on cells lacking the receptor. The construct can be used for enhancing PDGF response of cells, determining the regions involved in transducing the signal in response to PDGF binding, providing mutated analogs and evaluating drugs for their physiologic activity.
