malignant b cell lymphomas vs benign lymphoproliferations and the role of immunoglobulin heavy chain gene rearrangement analysis
abstract background and objectives malignant lymphoma may be very difficult to be diagnosed through routine histopathological methods because they may mimic reactive architecture or contain reactive infiltrates. detection of the monoclonal lymphocyte population is one of the best methods of diagnosis since a monoclonal proliferation is strongly suggestive of neoplasia. by means of a pcr method...
متن کاملImmunoglobulin heavy chain gene rearrangement and transcription in murine T cell hybrids and T lymphomas.
We have examined the arrangement of immunoglobulin heavy chain constant (CH) and joining (JH) region genes in murine T cell hybrid lines and in T lymphomas. CH genes derived from both parental cell types were present in all hybrids for which polymorphism in sequences flanking CH genes permitted us to distinguish parental CH genes. All T lymphomas and T cell hybrids retained the C alpha gene in ...
متن کاملRegulation of immunoglobulin heavy-chain gene rearrangements.
Regulated assembly of antigen receptor gene segments to produce functional genes is a hallmark of B- and T-lymphocyte development. The immunoglobulin heavy-chain (IgH) and T-cell receptor beta-chain genes rearrange first in B and T lineages, respectively. Both loci require two recombination events to assemble functional genes; D-to-J recombination occurs first followed by V-to-DJ recombination....
متن کاملDiagnostic value of immunoglobulin κ light chain gene rearrangement analysis in B-cell lymphomas
Analysis of the immunoglobulin κ light chain (IGK) gene is an alternative method for B-cell clonality assessment in the diagnosis of mature B-cell proliferations in which the detection of clonal immunoglobulin heavy chain (IGH) gene rearrangements fails. The aim of the present study was to evaluate the added value of standardized BIOMED-2 assay for the detection of clonal IGK gene rearrangement...
متن کاملHeavy chain immunoglobulin gene rearrangement in acute nonlymphocytic leukemia.
Samples of leukemic cell DNA from 14 children with acute nonlymphocytic leukemia (ANLL) and 4 human myeloid leukemia cell lines were analyzed for rearrangement in the heavy chain region of the immunoglobulin gene. The diagnosis of ANLL was confirmed in all patients by morphological, cytochemical, and immunologic studies. By restriction endonuclease digestion and hybridization with cloned heavy ...
