TLDR
It is demonstrated in macrophages and B cells that collaborative interactions of the common factor PU.1 with small sets of macrophage- or B cell lineage-determining transcription factors establish cell-specific binding sites that are associated with the majority of promoter-distal H3K4me1-marked genomic regions.

YY1 Haploinsufficiency Causes an Intellectual Disability Syndrome Featuring Transcriptional and Chromatin Dysfunction

TL;DR: A clinical syndrome caused by haploinsufficiency of YY1 through dysregulation of key transcriptional regulators is defined, defined as a syndrome of cognitive impairment, behavioral alterations, intrauterine growth restriction, feeding problems, and various congenital malformations.

Therapeutic Ligands Antagonize Estrogen Receptor Function by Impairing Its Mobility.

TL;DR: Mechanistically, fulvestrant-like antagonists suppress ER transcriptional activity not by ER elimination, but by markedly slowing the intra-nuclear mobility of ER, providing proof-of-concept that small molecule perturbation of transcription factor mobility may enable therapeutic targeting of this challenging target class.
Journal ArticleDOI

Transcriptome-wide Analysis of Roles for tRNA Modifications in Translational Regulation.

TL;DR: This data build on prior reports documenting translational upregulation of the nutrient-responsive transcription factor Gcn4 in response to numerous tRNA perturbations, and identify many additional translationally regulated mRNAs throughout the yeast genome.
Journal ArticleDOI

Uncovering cis-regulatory sequence requirements for context-specific transcription factor binding

TL;DR: This study establishes a novel approach to derive predictive cis-regulatory motif requirements for individual TF binding sites and enhancers from the increasing number of tissue- and cell-type-specific TF binding studies.

High-resolution profiling of histone methylations in the human genome.

TL;DR: High-resolution maps for the genome-wide distribution of 20 histone lysine and arginine methylations as well as histone variant H2A.Z, RNA polymerase II, and the insulator binding protein CTCF across the human genome using the Solexa 1G sequencing technology are generated.

RAG-1-deficient mice have no mature B and T lymphocytes

TL;DR: The introduction of a mutation in RAG-1 into the germline of mice via gene targeting in embryonic stem cells is described and it is shown that this mutation either activates or catalyzes the V(D)J recombination reaction of immunoglobulin and T cell receptor genes.
Journal ArticleDOI

Genome-scale DNA methylation maps of pluripotent and differentiated cells

TL;DR: Low-throughput reduced representation bisulphite sequencing is established as a powerful technology for epigenetic profiling of cell populations relevant to developmental biology, cancer and regenerative medicine.
