We used 454 sequencing to assess the repertoire of B cell subsets from bone marrow, spleen, and small intestinal lamina propria from two mouse strains. We used a RAG2-GFP reporter mouse strain (129Sve background) to isolate CD19+ RAG2+ B lineage cells from bone marrow and small intestinal lamina pro...
ORGANISM(S): Mus musculus 
We used a RAG2-GFP reporter mouse to show that RAG+ B lineage cells can be found in the small intestinal lamina proria in normally-housed mice at weaning age. We used microarry expression analysis to compare the RAG2+ population in the gut to the RAG2+ B lineage population in the bone marrow. Microa...

Repair of DNA double-strand breaks (DSBs) by non-homologous end-joining is critical for neural development, and brain cells frequently contain somatic genomic variations that might involve DSB intermediates. We now use an unbiased, high-throughput approach to identify genomic regions harboring recur...

This research identifies a novel protein required for paramutation at the maize purple plant1 locus. This 'required to maintain repression2' (RMR2) protein represents the founding member of a plant-specific clade of hypothetical proteins. We show that RMR2 is required for transcriptional repression ...
