Abstract: Characteristic of chronic myelogenous leukemia (CML) is the presence of the chimeric p120.sup.bcr-abl protein possessing elevated protein tyrosine kinase activity relative to normal c-abl tyrosine kinase. Hematopoietic progenitors isolated from CML patients in the chronic phase contain a constitutively tyrosine phosphorylated protein that migrates at approximately 62 kDa by SDS-PAGE and associates with the p120 ras GTPase-activating protein (GAP). This novel protein, called p62.sup.dok (p62 protein downstream of tyrosine kinases), was isolated from a hematopoietic cell line expressing p120.sup.bcr-abl. Association of p62.sup.dok with GAP correlates with its tyrosine phosphorylation. p62.sup.dok is rapidly tyrosine phosphorylated upon activation of the c-kit receptor, implicating it as a component of a signal transduction pathway downstream of receptor tyrosine kinases.

Abstract: A cancer prognostic having particular utility in the prognosis of head and neck squamous cell cancer, in which the expression levels of either or both of Transforming Growth Factor Alpha (TGF-.alpha.) or Epidermal Growth Factor Receptor (EGFR) are assayed directly from a sample of tumor tissue. The expression level once quantitated is normalized as to standard, and the standardized expression level is compared to the prognostic threshold of about 83% of standard for TGF-.alpha. or of about 23% of standard for EGFR, or the corresponding upper threshold of the "low" tertile regardless of how calculated. Virtually all if not all patients demonstrating this low expression level survive at least five years after initial diagnosis, assuming completion of treatment with standard surgical tumor excision and radiation protocols for squamous cell head and neck cancer. Whether an individual patient's expression levels of TGF-.alpha.

Abstract: The invention provides a method to prevent or ameliorate hyperacute or acute rejection of a human donor organ transplanted to a human recipient. Hyperacute rejection would normally occur after a human subject receives a transplanted human organ against which the subject has preformed anti-HLA antibodies.

The invention method comprises passing the plasma of the recipient over a sterile and pyrogen-free column coupled to anti-human immunoglobulin antibodies which bind to and remove a significant portion of the immunoglobulin from the subject's plasma.
