Description
We report the effects of Rapamycin treatment on the transcriptome of normal human dermal fibroblasts isolated from foreskin (designated 2DD). We sequenced mRNA from 2 replicates of proliferative (PRO) quiescent (QUI, serum starved) or treated with 500nM Rapamycin for 5 days (RAP). Comparative analyses with PRO transcripts a baseline indicate that genes that changed expression from Rapamycin treated fibroblasts are significantly different from those of quiescence cells. Rapamycin treated cells showed a significant enrichment for cytokines from the Il-6 cascade. Overall design: Examination of mRNAs from proliferative, quiescent (serum starvation) and Rapamycin (5oonM, 5days) treated 2DD normal human dermal/foreskin fibroblasts.

Description
We analyzed the global effect of c-Myb knockdown by sequencing the transcriptomes of K-562 cells transfected with control siRNA and si2992 (MYB knockdown), as well as K-562 cells stably expressing TY-tagged wild type c-Myb and c-Myb D152V transfected with si2992 Overall design: Cells were tranfected with siRNA and 24 hours after total RNA was extracted. Three individual experiments were performed. Libraries were prepared and 125-bp paired-end reads were obtained using an Illumina HiSeq 2500 sequencer
Publication Title
A c-Myb mutant causes deregulated differentiation due to impaired histone binding and abrogated pioneer factor function.

Description
Identify genes in the aorta whose expressions under genetic regulation in the Hybrid Mouse Diversity Panel (HMDP). The HDMP is comprised of classical inbred and recombinant inbred wild-type mice. The RMA values of genes were used for genome-wide association as described in Bennett et al. Genome Research 2010 (PMID 20054062). These data were used to identify candidate genes at loci associated with atherosclerosis.

Description
Linkage analysis of complex traits in mice is a powerful tool to find loci affecting the phenotype but it has a poor resolution making it difficult to identify the underlying genes. We show here, using whole genome association analysis of gene expression traits in an outbred mouse population, the MF1 stock, that mapping resolution is greatly increased as compared to linkage. The fact that eQTLs discovered in other crosses were replicated and successfully mapped with high resolution in this population provides a strong proof of concept. In addition, we show that this population is a useful resource to resolve the eQTL hotspots detected in other studies. Finally, we highlight the importance of correcting for population structure in whole genome association studies in the outbred stock.

Description
Two distinct Polycomb complexes, PRC1 and PRC2, collaborate to maintain epigenetic repression of key developmental loci in embryonic stem cells (ESCs). PRC1 and PRC2 have histone modifying activities, catalyzing mono-ubiquitination of histone H2A (H2AK119u1) and trimethylation of H3 lysine 27 (H3K27me3) respectively. Compared to H3K27me3, localization and role of H2AK119ub1 is not fully understood in ESCs. Here we present genome-wide H2AK119u1 maps in ESCs and identify a group of genes at which H2AK119u1 is deposited in a Ring1-dependent manner. These genes are a distinctive subset of genes with H3K27me3 enrichment and are the central targets of Polycomb silencing that are required to maintain ESC identity. We further show that the H2A ubiquitination activity of PRC1 is dispensable for its target binding and its activity to compact chromatin at Hox loci, but is indispensable for efficient repression of target genes and thereby ESC maintenance. These data demonstrate that multiple effector mechanisms including H2A ubiquitination and chromatin compaction combine to mediate PRC1-dependent repression of genes that are crucial for the maintenance of ESC identity. Utilization of these diverse effector mechanisms might provide a means to maintain a repressive state that is robust yet highly responsive to developmental cues during ES cell self-renewal and differentiation.
