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.

CODEX: a next-generation sequencing experiment database for the haematopoietic and embryonic stem cell communities

TL;DR: CODEX provides one of the most complete resources of publicly available NGS data for the direct interrogation of transcriptional programmes that regulate cellular identity and fate in the context of mammalian development, homeostasis and disease.
Journal ArticleDOI

Tissue-specific RNA expression marks distant-acting developmental enhancers.

TL;DR: The results demonstrate that tissue-specific e RNA expression is a common feature of in vivo enhancers, as well as a major source of extragenic transcription, and that eRNA expression signatures can be used to predict tissue- specific enhancers independent of known epigenomic enhancer marks.

Region-specific RNA m6A methylation represents a new layer of control in the gene regulatory network in the mouse brain

TL;DR: The results imply that RNA m6A methylation is a newly identified element in the region-specific gene regulatory network in the mouse brain, and is likely to be used for selective recognition of target mRNAs by FMRP in the synapse.
Journal ArticleDOI

Metabolic control of regulatory T cell (Treg) survival and function by Lkb1.

TL;DR: This work defines a metabolic checkpoint in Tregs that couples metabolic regulation to immune homeostasis and tolerance and highlights LKB1 as metabolic regulator that links cellular metabolism to immune cell functions.

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.
Journal ArticleDOI

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.
