Previous experiments have suggested an important role for the Ig enhancers and transcription in targeting somatic hypermutation. To determine whether the requirement of the enhancers is Ig chain specific, we analyzed two lambda 2 light chain transgen

A strong transcriptional enhancer was identified for the human lambda L chain Ig gene complex. Enhancer activity was measured by activation of the chloramphenicol acetyl transferase (CAT) gene in a transient assay using both mouse and human B lymphoi

A rearrangement test gene, pHRD, containing the mouse IgH enhancer and the metallothionein promoter, has previously been shown to rearrange efficiently after transfection into a pre-B cell line. Experiments are now reported that assess the requiremen

A cDNA clone was isolated from a mouse pre-B cell line, the sequence of which has a very high homology with rat and human thymosin beta 4 genes. However, the mouse clone has an insertion of 98 bp relative to the published rat and human sequences upst

This review describes studies on somatic hypermutation of immunoglobulin genes that were started in the mid-80s in collaboration with Ralph Brinster. Almost all of the experiments were carried out using Ig transgenes as targets for the somatic mutati

We have characterized a novel substrate for somatic hypermutation, confirming that non-Ig sequences can be targeted for mutation and demonstrating that this substrate allows for the rapid assay for mutations. An artificial sequence containing alterna

gamma 2b transgenic mice have a severe B cell defect, apparently caused by strong feedback inhibition of endogenous H-gene rearrangement coupled with an inability of gamma 2b to provide the survival/maturation functions of mu. A unique gamma 2b trans

Transgenic mice are discussed which carry a rearrangement test transgene. The methylation status of the transgene varies, depending on the background mouse strain. When the transgene is bred into the C57BL/6 strain, it is completely methylated and no

Experiments with transgenic mice carrying rearranged Ig transgenes have shown that membrane bound Ig molecules cause feedback inhibition of endogenous Ig gene rearrangement. However, this inhibition is never complete. It has been postulated that esca
