The heritability of B cell chronic lymphocytic leukemia (CLL) is relatively high; however, no predisposing mutation has been convincingly identified. We show that loss or reduced expression of death-associated protein kinase 1 (DAPK1) underlies cases of heritable predisposition to CLL and the majority of sporadic CLL. Epigenetic silencing of DAPK1 by promoter methylation occurs in almost all sp...
BCR signaling pathway inhibitors such as ibrutinib, idelalisib, and fostamatinib (respective inhibitors of Bruton's tyrosine kinase, PI3Kδ, and spleen tyrosine kinase) represent a significant therapeutic advance in B cell malignancies, including chronic lymphocytic leukemia (CLL). These drugs are distinctive in increasing blood lymphocytes while simultaneously shrinking enlarged lymph nodes, su...
Chronic Lymphocytic Leukemia (CLL) is one of the most common forms of adult leukemia in North Americans. However, it has been shown through the analysis of clinical studies and synopses of medical research that no current treatment indefinitely cures CLL or prolongs the life of CLL patients. Current CLL therapies are either symptomatic treatments (chemotherapy and immunotherapy) that do not imp...
BACKGROUND AND OBJECTIVES Chromosome band 11q23 is frequently deleted in various types of neoplasm. The region represented by yeast artificial chromosome (YAC) clone 755b11 at 11q23 has been shown to be the minimal common region of deletion in mantle cell lymphoma (MCL) and B-cell chronic lymphocytic leukemia (B-CLL). The aim of the study was to determine the frequencies of 11q23 deletion in di...
The B-cell receptor (BCR) is a key survival molecule for normal B cells and for most B-cell malignancies. Recombinatorial and mutational patterns in the clonal immunoglobulin (Ig) of chronic lymphocytic leukemia (CLL) have revealed 2 major IgMD-expressing subsets and an isotype-switched variant, each developing from distinct B-cell populations. Tracking of conserved stereotypic features of Ig v...
To investigate whether a history of hematolymphoproliferative cancers (HLP) and other cancers among a parent or sibling is a risk factor for specific subtypes of leukemia and non-Hodgkin's lymphoma (NHL), data from a population-based case-control study, in Iowa and Minnesota, of 578 leukemia cases, 622 NHL cases and 1245 controls were evaluated. Having at least one sibling with HLP significantl...
UNLABELLED The prevalence of paraneoplastic neurologic syndrome in cancer is 0.01%. Neurological syndromes can be seen in chronic lymphocytic leukemia (CLL) and mostly present as either leukemic infiltration of the central nervous system (CNS) or progressive multifocal leukoencephalopathy. To our knowledge, this is the first reported case of combined sensory-motor neuropathy, myopathy, and derm...
Introduction: CLL is one of the most common leukemias, which is categorized by the accumulation of mature CD5+ B-lymphocytes in the peripheral blood, bone marrow, and secondary lymphoid organs. In this study, the status of rs6449182 polymorphism of the CD38 gene and its association with clinical and laboratory parameters of CLL patients was evaluated. Methods: Genomic DNA extraction was perfor...
MicroRNA-155-5p (miR-155-5p) is a proinflammatory, oncogenic miRNA, involved in various physiological processes, including hematopoiesis, immunity, inflammation, and cell lineage differentiation. It regulates important transcription factors, such as E2F2, hypoxia-inducible factor 1 (HIF1), and FOXO3. Recently, the dysregulation of miR-155-5p expression has been linked to chronic lymphocytic leu...
BACKGROUND High purity of tumour samples is a necessity for accurate genetic and expression analysis and is usually achieved by positive selection in chronic lymphocytic leukaemia (CLL). RESULTS We adapted a bifunctional rosette-based antibody cocktail for negative selection of B-cells for isolating CLL cells from peripheral blood (PB). PB samples from CLL patients were split into aliquots. O...
