The immunoglobulin heavy-chain (Igh) locus undergoes large-scale contraction in pro-B cells, which facilitates VH-DJH recombination by juxtaposing distal VH genes next to the DJH- rearranged gene segment in the proximal Igh domain. By high-resolution mapping of long-range interactions, we now demons...

Background: This study examines the impact of dietary fatty acids on regulation of gene expression in the mammary epithelial cells before and during puberty. Methods: The diets primarily consisted of n-9 monounsaturated fatty acids (olive oil), n-6 polyunsaturated fatty acids (safflower), saturated ...

VH-DJH recombination of the immunoglobulin heavy-chain (Igh) locus is temporally and spatially controlled during early B-cell development, and yet no regulatory elements other than the VH gene promoters have been identified throughout the entire 2.5-Mb VH gene cluster. Here we discovered novel regul...

Wildtype and Mt1(-/-)Mt2(-/-) double knockout 129S1/SvImJ strain mouse lungs were compared in their response to nickel aerosol exposure at 3, 8, 24, 48, and 72 hrs.

Wildtype vs. Ahr(-/-) mouse embryo fibroblast cells were compared in a flipped-dye design

We compared the global gene expression profiles of C57BL/6 mice aortas with the profiles of cultured vascular smooth muscle cells (vSMC) from the same mice, and determined whether gene responses to dioxin exposure in the vSMCs would be predictive of responses in the aorta.
