TranscriptomicsGenome-wide profiling of PRC1 and PRC2 Polycomb chromatin binding in Drosophila
Polycomb group (PcG) proteins maintain transcriptional repression of developmentally important genes and have been implicated in cell proliferation and stem-cell self-renewal. We used a genome-wide approach to map binding patterns of PcG proteins (Pc, esc and Sce) in Drosophila Kc cells. We found th...

TranscriptomicsInteractions among Polycomb domains are guided by chromosome architecture
Polycomb group (PcG) proteins bind and regulate hundreds of genes. Previous evidence has suggested that long-range chromatin interactions may contribute to the regulation of PcG target genes. Here, we adapted the Chromosome Conformation Capture on Chip (4C) assay to systematically map chromosomal in...

TranscriptomicsMapping of H3K27me3 enrichment in Drosophila larval brain tissue using ChIP-chip
We made Polycomb (PC) and histone H3 lysine 27 trimethylation (H3K27me3) chromatin binding maps in central brain tissue from 3rd instar larvae, allowing us to make a direct comparison to our 4C data (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE23166). Our results demonstrate that our PC and...

TranscriptomicsGene expression profiling in wild type and In(3LR)sep larval brain tissue (Drosophila)
We performed a series of microarray expression profile experiments in central brain tissue from 3rd instar larvae, interrogating expression differences between wild type and In(3LR)sep strains. Since our 4C data (http://www.ncbi.nlm.nih.gov/geo/query/acc.cgi?acc=GSE23166), demonstrated dramatic chan...
