    摘要: Variants (mutants) of recombinant activated protein C (APC) or recombinant protein C (prodrug, capable of being converted to APC) that have substantial reductions in anticoagulant activity but that retain normal levels of anti-apoptotic activity are provided. Two examples of such recombinant APC mutants are KKK191-193AAA-APC and RR229/230AA-APC. APC variants and prodrugs of the invention have the desirable property of being cytoprotective (anti-apoptotic effects), while having significantly reduced risk of bleeding. The invention also provides a method of using the APC variants or prodrugs of the invention to treat subjects who will benefit from APC's cytoprotective activities that are independent of APC's anticoagulant activity. These subjects include patients at risk of damage to blood vessels or tissue in various organs caused, at least in part, by apopotosis. At risk patients include, for example, those suffering (severe) sepsis, ischemia/reperfusion injury, ischemic stroke, acute myocardial infarction, acute or chronic neurodegenerative diseases, or those undergoing organ transplantation or chemotherapy, among other conditions. Methods of screening for variants of recombinant protein C or APC that are useful in accordance with the invention are also provided.

    摘要: The present invention provides novel PAR1 derived cytoprotective oligopeptides or polypeptides which typically contain at least the first 4 N-terminal residues that are substantially identical to the corresponding N-terminal residues of Met1-Arg46 deleted human PAR1 sequence. These cytoprotective oligopeptides or polypeptides are capable of activating PAR1 and promoting PAR1 cytoprotective signaling activities. The invention also provides engineered cells or transgenic non-human animals which harbor in their genome an altered PAR1 gene that is resistant to cleavage at Arg41 and/or Arg46 residues. Additionally provided in the invention are methods of screening candidate compounds to identity additional cytoprotective compounds or cytoprotective proteases. The invention further provides therapeutic use or methods of employing a PAR1 derived cytoprotective oligopeptide or polypeptide to treat conditions associated with tissue injuries or undesired apoptosis.

    摘要: The present invention provides methods for revealing, detecting, and analyzing circulating tumor cells in the blood of a subject. Revealing detectable circulating tumor cells allows for early stage detection and diagnosis in addition to long term prognosis in subjects with cancer. Additionally, enrichment allows for robust detection and clinically meaningful analysis of low volume samples for use in clinical settings as well as innovative methods for the treatment of cancers.

    摘要: Oncokinase fusion polypeptides associated with hyperproliferative disorders and the polynucleotides encoding for such fusion polypeptides are provided. The fusion polypeptides have a C-terminal tyrosine kinase domain fused to an N-terminal domain that is not normally fused to the C-terminal tyrosine kinase domain and they possess constitutively activated tyrosine kinase activity. Also provided are methods for detecting and identifying the fusion polypeptides and polynucleotides and methods of diagnosing disease conditions associated with the fusion polypeptides and polynucleotides. In addition, screening assays for identifying agents useful for treating disease conditions associated with such fusion polypeptides and polynucleotides are provided. Furthermore, methods of treating disease conditions associated with the presence of the fusion polypeptides are provided.
