  1. ...and time drives the successful development and sustained health of all organisms. To understand the underlying causes of developmental disorders, polygenic diseases, and cancer, we must decipher the code that directs gene expression in diverse cell types and environments. Transcription factors (TFs) bind...
  2. ...chromatin may stop the spreading of nearby repressive chromatin. Linear clustering would then reduce the number of interfaces with repressive chromatin and thus stabilize expression. In the second scenario, housekeeping genes may be stimulated by specific enhancers (Zabidi et al. 2015). Clustering around...
  3. ...et al. 2019) and impeding the binding of diverse transcription factors (TFs) and RNA polymerase, unlike H3K27me3-marked domains (Becker et al. 2016, 2017).Loss of heterochromatin has been proposed as a potential universal molecular cause of aging, whereby over time, heterochromatin domains lose...
  4. ...). A large and diverse set of gene regulatory elements in chromatin are found to regulate transcription through long-range interactions. For example, promoter–enhancer interactions regulate the dynamic activation of genes (Cloney 2016), whereas insulators and repressors play the opposite roles (Yang...
  5. ...research has shown that TAD borders are enriched in housekeeping genes (Li et al. 2015), developmental enhancers (Cubeñs-Potts et al. 2017), and boundaries of highly conserved genomic regulatory blocks (Harmston et al. 2017). In addition, architectural proteins and insulators are enriched at TAD borders...
  6. ...; Supplemental Fig. S3). In the hemoglobin subunit beta (HBB) cluster locus, three chromatin accessibility peaks were shared across many different cell types, despite the fact that H3K4me1 and H3K27ac ChIP-seq peaks, RNA-seq transcripts, and 24 DNase-seq peaks were specific to K562 cells (Fig. 1C). We observed...
  7. ...contribute to -wide transcriptional regulation.Gene expression networks underlie many cellular processes (Spitz and Furlong 2012). These expression networks are controlled in cis by DNA regulatory elements, such as promoters and enhancers, which can be proximal, can be distal, or can be within their target...
  8. ...equivalent transcripts and are generally clustered together and analyzed as a single transcriptional unit termed a tag cluster (Haberle et al. 2015). The CTSS with the highest TPM value within a tag cluster is referred to as the dominant CTSS. Specificity in capturing genuine TSSs can be assessed...
  9. ...spaced promoters to control rhythmic transcription with spatial precision.View larger version: In this window In a new window Figure 6. Precise promoter-enhancer contacts underlie liver-specific mRNA rhythms. (A,B) 4C-seq profiles for the (A) Slc45a3-short and (B) Slc45a3-long isoforms within ±250 kb...
  10. ...; (2) new TSSs undergo rapid evolution that reduces the inherent instability of repeat sequences associated with a high propensity of TSS emergence; and (3) once established, the transcriptional competence of surviving TSSs is gradually enhanced, with evolutionary changes subject to temporal (fewer...
