Multiple chromosomal rearrangements in a spontaneously arising t(6;7) rat immunocytoma juxtapose c-myc and immunoglobulin heavy chain sequences.
Spontaneously arising immunocytomas in Lou/Wsl rats contain a consistent translocation between chromosomes 6 and 7. The c-myc gene has been localized to chromosome 7 and has been shown to be rearranged in the majority of the rat immunocytomas. We now report the cloning of the rearranged 11-kilobase EcoRI c-myc fragment from the IgE-secreting IR75 tumor. Sequence analysis revealed that the cytog...
متن کاملRearrangement and Expression of Immunoglobulin Light Chain Genes Can Precede Heavy Chain Expression during Normal B Cell Development in Mice
In mouse mutants incapable of expressing mu chains, VkappaJkappa joints are detected in the CD43(+) B cell progenitors. In agreement with these earlier results, we show by a molecular single cell analysis that 4-7% of CD43(+) B cell progenitors in wild-type mice rearrange immunoglobulin (Ig)kappa genes before the assembly of a productive VHDHJH joint. Thus, mu chain expression is not a prerequi...

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 کاملRearrangement of immunoglobulin heavy chain genes in T cell acute lymphoblastic leukemia.
We studied the arrangement of the immunoglobulin heavy chain genes by Southern blot analysis of DNA freshly obtained from marrow blast cells of 14 children with T cell acute lymphoblastic leukemia (T-ALL) using probes to the C mu and JH gene segments: At least one of the C mu-gene alleles was rearranged in three cases. In two of these, one C mu gene had the germ-line configuration and one was r...
متن کاملConsensus primers for detecting monoclonal immunoglobulin heavy chain rearrangement in B cell lymphomas.
AIMS To demonstrate the usefulness of polymerase chain reaction (PCR) methodology with both the FR2A/LJH/VLJH and the FR1c/LJH/VLJH primer sets for detecting monoclonal immunoglobulin heavy chain (IgH) gene rearrangement in B cell non-Hodgkin lymphomas (B-NHLs). METHODS Eighty three patients with B-NHL were enrolled in this study. DNA was isolated from paraffin wax embedded sections and ampli...
