Variable heavy-chain gene analysis of follicular lymphomas: subclone selection rather than clonal evolution over time.

To investigate B-cell receptor evolution in follicular lymphomas (FLs), immunoglobulin variable heavy chain (V(H)) gene regions of 3 FLs were analyzed at different time points. One FL with a high somatic mutation load and intraclonal V(H) gene diversity was investigated in situ. V(H) gene transcripts were amplified and sequenced from samples of approximately 50 tumor cells isolated from frozen ...

Variable heavy chain gene analysis of follicular lymphomas: correlation between heavy chain isotype expression and somatic mutation load.

The expansion of follicular lymphomas (FLs) resembles, both morphologically and functionally, normal germinal center B-cell growth. The tumor cells proliferate in networks of follicular dendritic cells and are believed to be capable of somatic hypermutation and isotype switching. To investigate the relation between somatic mutation and heavy chain isotype expression, we analyzed the variable he...

High Throughput Sequencing Analysis of the Immunoglobulin Heavy Chain Gene from Flow-Sorted B Cell Sub-Populations Define the Dynamics of Follicular Lymphoma Clonal Evolution

Understanding the dynamics of evolution of Follicular Lymphoma (FL) clones during disease progression is important for monitoring and targeting this tumor effectively. Genetic profiling of serial FL biopsies and examples of FL transmission following bone marrow transplant suggest that this disease may evolve by divergent evolution from a common ancestor cell. However where this ancestor cell re...

Polymorphisms of a human variable heavy chain gene show linkage with constant heavy chain genes.

In this study, restriction fragment length polymorphisms (RFLPs) were identified with an immunoglobulin variable heavy chain region (Ig VH) probe and the inheritance of the polymorphisms was analyzed in families. Linkage within the VHII gene cluster and between the VHII and Ig CH genes was investigated by lod (logarithm of odds) score analysis. In addition, the position of the VHII genes was de...

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...
