• RAG-1 and ATM coordinate monoallelic recombination and nuclear positioning of immunoglobulin loci.

  Coordinated recombination of homologous antigen receptor loci is thought to be important for allelic exclusion. Here we show that homologous immunoglo…

• A novel role for Xist RNA in the formation of a repressive nuclear compartment into which genes are recruited when silenced.

  During early mammalian female development, one of the two X chromosomes becomes inactivated. Although X-chromosome coating by Xist RNA is essential fo…

• Differential histone H3 Lys-9 and Lys-27 methylation profiles on the X chromosome.

  Histone H3 tail modifications are among the earliest chromatin changes in the X-chromosome inactivation process. In this study we investigated the rel…

• Unravelling the evolutionary origins of X chromosome inactivation in mammals: insights from marsupials and monotremes.

  Determining the evolutionary origin of X inactivation mechanisms in mammals requires knowledge of features of X inactivation across all three major ma…

• Combined immunofluorescence, RNA fluorescent in situ hybridization, and DNA fluorescent in situ hybridization to study chromatin changes, transcriptional activity, nuclear organization, and x-chromosome inactivation.

  Epigenetic mechanisms lead to the stable regulation of gene expression without alteration of DNA and trigger initiation and/or maintenance of cell-typ…

• Specific patterns of histone marks accompany X chromosome inactivation in a marsupial.

  The inactivation of one of the two X chromosomes in female placental mammals represents a remarkable example of epigenetic silencing. X inactivation o…
