ZAP-70 methylation status is associated with ZAP-70 expression status in chronic lymphocytic leukemia.
BACKGROUND AND OBJECTIVES ZAP-70 expression is a recognized prognostic marker in chronic lymphocytic leukemia (CLL). The aim of this study was to analyze whether the methylation status of the ZAP-70 gene is associated with expression of the ZAP-70 protein. DESIGN AND METHODS Patients with CLL (n=87), acute lymphoblastic leukemia (n=13), mantle cell leukemia (n=13) and splenic marginal zone ly...
متن کاملExpression of ZAP-70 is associated with increased B-cell receptor signaling in chronic lymphocytic leukemia.
We examined isolated leukemia B cells of patients with chronic lymphocytic leukemia (CLL) for expression of zeta-associated protein 70 (ZAP-70). CLL B cells that have nonmutated immunoglobulin variable region genes (V genes) expressed levels of ZAP-70 protein that were comparable to those expressed by normal blood T cells. In contrast, CLL B cells that had mutated immunoglobulin variable V gene...
متن کاملAnalysis of HLA-G Gene Expression in B-Lymphocytes from Chronic Lymphocytic Leukemia Patients
The human leukocyte antigen G (HLA-G) molecule exhibits limited tissue distribution, low polymorphism and alternative splicings that generate seven HLA-G isoforms. HLA-G exerts multiple immunoregulatory functions. Recent studies indicate an ectopic up-regulation in tumor cells that may favor their escape from anti-tumor immune responses. This study it is an effort to clarify the presence of HLA...

متن کاملMulticenter study of ZAP-70 expression in patients with B-cell chronic lymphocytic leukemia using an optimized flow cytometry method.
BACKGROUND Flow cytometry allows specific assessment of the expression of ZAP-70, a promising new prognostic factor in B-cell chronic lymphocytic leukemia (B-CLL), but suffers from a lack of multicenter standardization. DESIGN AND METHODS An optimized method for direct detection of ZAP-70 in flow cytometry was tested in a multicenter fashion. Adapted for frozen cells, this method includes a n...
