  1. ...transcriptional and chromatin differences between cells in culture and grown as xenografts.View larger version: In this window In a new window Figure 4. Nanodroplet FAIRE identifies cell-type-specific regions of accessible chromatin from FFPE xenograft tissue. (A) Normalized FAIRE-seq sequencing tracks of EWS894...
  2. ...-mers in the vicinity (Fig. 1A). Once the SCM has discovered the chromatin accessibility code words and their spatial patterns from cell-type–specific training data, it can output predicted chromatin accessibility patterns for any DNA sequence, be it genomic DNA or novel DNA sequence. Since our model is trained...
  3. ...cells showed a genomic profile highly similar to that of the corresponding bulk cells at the cell type–specific gene loci including PAX5, CD19, CD14, CD93, CD3D, CD5, TBX21, and NCR1 (Fig. 3C). By comparing the cell type–specific peaks identified from the ENCODE data and cluster-specific peaks...
  4. ...–treated chromatin (DNase-seq) allows high-resolution measurement of chromatin accessibility to DNase I cleavage, permitting identification of de novo active cis-regulatory modules (CRMs) and individual transcription factor (TF) binding sites. We adapted DNase-seq to nuclei isolated from C. elegans embryos and L1...
  5. ...is organized as a highly dynamic structure in a cell-type–specific manner and is tightly coupled with gene transcription (Cavalli and Misteli 2013; Sawyer and Dundr 2017; Wang et al. 2017; Watson and Tsai 2017). Chromatin domains can be subdivided into transcriptionally active and inactive territories based...
  6. ...investigated cell types increased, the frequencywithwhich they were identified in multiple cell types increased (Fig. 1F). Some promoters function at very low levels in a highly cell type-specific manner (Landry et al. 2003; Davuluri et al. 2008). Nevertheless, we were concerned that many of the minor TSCs...
  7. ...IP from low-density chromatin fractions allows ORI purification. Genome-wide validation of the newly identified ORIs Our finding that randomly selected ORC1 binding regions are active ORIs suggests that the ORC1 data set identifies ORIs on a -wide scale. Unfortunately, we could not test this Figure 2...
  8. ...in instructing cell type–specific gene expression patterns (Niwa 2018; Stadhouders et al. 2019). In addition, chromatin undergoes covalent histone modifications and DNA methylation, which further recruit chromatin modifying factors to impart precise catalysis of transcription and enhance or repress gene...
  9. ...stages and types. Our enhanced procedure yielded sufficient amounts of clean NS samples (Methods; Fig. 1A; Supplemental Fig. S1). Briefly, after nuclei purification, NS were purified from DNA replication bubbles by sucrose gradient centrifugation to isolate DNA fragments of appropriate size in several...
  10. ...with GR regulatory elements (GREs) for chromatin conformation and for the lifetime of the GR-induced hypersensitivity are largely unknown. Chromatin conformation determines access to a variety of DNA regulatory elements, shaping transcriptional responses in a tissue- and cell-type-specific manner (Stalder...
