(Submitter supplied) The lens is comprised of the anterior lens epithelium and posterior lens fibers, which form the bulk of the lens. The RNAseq data enables identification of lens epithelium and fiber differentially expressed genes and temporally differentially expressed genes which were also validated by qRTPCR. The present RNA-seq data serves as a comprehensive reference resource for deciphering molecular principles of normal mammalian lens differentiation, mapping a full spectrum of signaling pathways and DNA-binding transcription factors operating in both lens compartments, and predicting novel pathways required to establish lens transparency.

(Submitter supplied) Using whole genome bisulfite sequencing (WGBS), we investigated dynamics of DNA methylation and chromatin changes during mouse lens fiber and epithelium differentiation between embryos (E14.5) and newborns (P0.5) using microdissected lenses. Histone H3.3 variant chromatin landscapes were also generated by ChIP-seq using microdissected newborn lenses.

(Submitter supplied) We performed ATAC-seq for microdissected lens epithelium and fiber from E14.5 and P0.5 mouse lenses.Through investigating dynamics of chromatin changes during mouse lens fiber and epithelium differentiation, we identified spatial-temporal differential accessible regions and the enriched known and novel motifs. We also discovered some novel and known enhancers for the transcription factors and structural genes that are important in lens development. more...

(Submitter supplied) The transcription factor Pax6 is comprised of the paired domain (PD) and homeodomain (HD). In the developing forebrain, Pax6 is expressed in ventricular zone precursor cells and in specific subpopulations of neurons; absence of Pax6 results in disrupted cell proliferation and cell fate specification. Pax6 also regulates the entire lens developmental program. To reconstruct Pax6-dependent gene regulatory networks (GRNs), ChIP-seq studies were performed using lens and forebrain chromatin from mice. more...

(Submitter supplied) The large antigen receptor (AgR) loci in T and B lymphocytes have many bound CTCF sites, most of which are only occupied in lymphocytes, while only the CTCF sites at the far end of each locus near enhancers or J genes tend to be bound in non-lymphoid cells also. However, despite the generalized lymphocyte restriction of CTCF binding in AgR loci, the Igκ locus is the only locus which also shows significant lineage-specificity (T vs. more...

(Submitter supplied) Mammalian genomes are organized into compartments, topologically-associating domains (TADs) and loops to facilitate gene regulation and other chromosomal functions. Compartments are formed by nucleosomal interactions, but how TADs and loops are generated is unknown. It has been proposed that cohesin forms these structures by extruding loops until it encounters CTCF, but direct evidence for this hypothesis is missing. more...

This study presents and validates a computational method to predict cohesin-and-CTCF binding sites that form intra-TAD DNA loops. more...

(Submitter supplied) Sequencing files provided here include mouse liver ChIP-seq for CTCF and the cohesin subunit Rad21. These files are part of a larger study where we describe features of Topologically Associating Domains (TADs) and their impact on liver gene expression, then use these features to computationally predict subTAD structures not otherwise readily identifiable due to the low resolution of Hi-C. Our findings reveal that CTCF-based subTAD loops maintain key insulating properties of TADs, and support the proposal that subTADs are formed by the same loop extrusion mechanism and contribute to nuclear architecture as intra-TAD scaffolds that further constrain enhancer-promoter interactions. more...

(Submitter supplied) Ctcf and cohesin are key players in the three dimensional organization of chromatin. Whereas genome-wide Ctcf binding has diverged substantially between species due to transposon-mediated motif expansions, demarcation of topologically associating domains (TADs) by Ctcf is remarkably well conserved. Yet, the Ctcf consensus motif poorly predicts TADs and the majority of Ctcf sites are not at TAD boundaries. more...

(Submitter supplied) The CCCTC-binding factor (CTCF) is widely regarded as a key player in chromosome organization in mammalian cells, yet direct assessment of its role in genome architecture and gene regulation has been difficult. Here, we use auxin-inducible degron techniques to acutely deplete CTCF to determine how loss of CTCF affect chromatin organization and gene expression. In mouse embryonic stem cells, depletion of CTCF results in rapid loss of chromatin loops anchored at CTCF-binding sites without major disruption to chromatin compartments and topological domains. more...

(Submitter supplied) CTCF plays a critical role in maintaining the three-dimensional (3D) chromatin organization, which is important for gene regulation, as it allows distal regulatory elements to come into proximity with one another. However, the detailed mechanism responsible for establishing and maintaining the recruitment of CTCF remains elusive. Here, we use in situ Hi-C to show that the ATP-dependent chromatin remodeler, Chd4, regulates intra-chromatin looping by controlling chromatin accessibility to conceal aberrant CTCF-binding sites in mouse embryonic stem cells (mESCs). more...
