Identification of a gene on chromosome 12q22 uniquely overexpressed in chronic lymphocytic leukemia.
The pathogenesis of chronic lymphocytic leukemia (CLL) is unknown but may involve aberrant activation of signaling pathways. Somatic hypermutations in rearranged immunoglobulin heavy-chain (IgVH) genes allow a division of CLL patients into 2 categories: mutated IgVH genes are associated with an indolent disease, whereas unmutated IgVH genes define an aggressive form. Using differential display ...
BACKGROUND AND OBJECTIVES Chemokine receptors are involved in tumor progression and several of these receptors, including CXCR3, are expressed by chronic lymphocytic leukemia (CLL) B cells. This study was aimed to examine a possible relationship between CXCR3 expression in CLL and the clinical evolution of the disease. DESIGN AND METHODS Using flow activated cell sorting (FACS), we analyzed t...
In the present study 55 IgVH genes amplified from three different anatomical regions of a rheumatoid arthritis (RA) patient were analyzed, adding further information on synovial B-cell maturation and recirculation in RA. This analysis demonstrated somatically mutated IgVh genes in all regions studied, with amino acid deletions and mixed IgVh molecules, suggesting the existence of a novel pathwa...
