  1. .... Some Alu elements that have accumulated point mutations over time have become enhancers (e.g., Norris et al. 1995; Gombart et al. 2009; Jacobsen et al. 2009; Zhang et al. 2019). In general, these evolutionarily older Alu elements that are “fixed” in the , homozygous present in all individuals, can...
  2. ...strand, suggesting that function related to endogenous transcription is driving the phenomenon. Similarly, we find that within Alu mobile element insertions, strand asymmetry favors the transcribed strand of the ancestral retrotransposon. The effect is consistent across the multiplicity of Alu elements...
  3. ...gene expression.Although public RNA-seq data are accumulating across a wide array of tissues and cells types, many of which are from coordinated efforts such as the Genotype-Tissue Expression (GTEx) (The GTEx Consortium 2020) and Encyclopedia of DNA Elements (ENCODE) (The ENCODE Project Consortium et...
  4. ...enhancers among ChIP peaks, whereas remaining peaks have no obvious regulatory function and may represent crosslinking artifacts. Genome-wide TP53 responsive enhancers are invariably used across cell types Unsophisticated enhancer logic, with only a single high-scoring TP53 binding site being necessary...
  5. ...are characteristic of the tissue type Principal component analysis (PCA) and cluster analysis of the unmethylated Alu repeats revealed specific signatures of each cell type (blood, normal colon, and tumor cells) ( Supplemental Fig. S16 ). Analysis of the remaining genomic elements also classified the samples...
  6. ...= 0.00321), consistent with a recent finding that most human Alus lack epigenetic features of active enhancers (Su et al. 2014). We also detected significant differences in sequence conservation between active and inactive sequences (GERP scores for active and inactive elements P = 4.069 × 10−5). We...
  7. ...cells, a core sequence in Alu repeats. We repeated the above motif analyses in distal FAIRE-only or DNase-only sites and found biologically relevant motifs. For example, DNase-only sites are most enriched for the same motifs as the combined open chromatin set in K562, GM12878, NHEK, and HepG2 (GATA1...
  8. ...to be methylated. The little-known SVA retroposon contains a GC-rich VNTR region, which embodies a CpG island between an Alu-derived region and an LTR-derived region. Only three such elements had previously been described ( Kawajiri et al. 1986 ; Zhu et al. 1992 ; Shen 1994 ), although their methylation has...
  9. ...flanking human Alu repeats are implicated in ependymomas (Xie et al. 2010). In addition, we have shown that the insulator activity of B1-X35S involves binding of parylated CTCF, an established insulator-binding protein involved in loop formation and the recruitment of repressive complexes to chromatin (Han...
  10. ...of CRS/repeat overlaps, including 1572 CRSs that overlap Alu elements. Evolutionary constraints on RNA structure do not necessarily coincide with evolutionary constraints on sequence. In particular, ∼50% of CRSs fall outside of conserved elements identified by phastCons (Siepel et al. 2005) in the 100...
