  1. ..., a fraction of the transcripts that shape the oocyte methylome originates from species-specific long terminal repeats (LTRs) of endogenous retroviruses (ERVs) (Veselovska et al. 2015; Brind'Amour et al. 2018). This phenomenon contributes to significant differences in the oocyte methylation pattern between...
  2. ...cryptic poly(A) signal but also, and more importantly, at the cognate, downstream endogenous shGAG poly(A) site, thereby enabling full-length EVD transcription. The proposed repression of premature termination by the U1 snRNP must be efficient because, as shown with endogenous EVD (Fig. 3B), accumulation...
  3. ...be endogenous retroviruses (ERVs) (Han et al. 2007; Liu et al. 2009; Tang and Liang 2019; Warren et al. 2020). It is, however, unknown whether TEs retrotranspose in macaque neuronal lineage cells. Here, we exploited an updated macaque reference assembly, which greatly improved TE annotations (Warren et al. 2020...
  4. .....org transposon is activating transcription or generating premature truncations. Given these limitations, we set out to determine whether we could use RNA-seq data obtained from SB-mutagenized tumors to identify how transposon insertion in a given tumor was affecting RNA transcripts of nearby loci. We show...
  5. ...of RNA-seq reads mapping to known transposable elements (TEs) revealed a general trend of derepression of TE transcription in CLL compared with normal cells (P = 0.0084) (Fig. 1B; Supplemental Fig. S19a; Methods, section ‘‘Transposable Elements’’). Among TE classes, Human Endogenous Retroviruses show...
  6. ...; Waterston et al. 2002 ). The complete sequencing of the human has left only a remote possibility that some LTR-retrotransposons might still be active, with the exception of a few still fully coding elements from the HERV-K(HML2) family of endogenous retroviruses ( Löwer et al. 1996 ; Mayer et al. 1999...
  7. ...the gene regulatory network of the cancer .One of the most important and well-studied guardians of genomic integrity, TP53 (protein product of TP53, also known as p53), leverages regulatory opportunities provided by TEs for its function. One group of TE families, human endogenous retroviruses (ERVs...
  8. ...32 esophageal cancer samples. We found that the exon skipping induced a frameshift and a premature termination codon in exon 21, which likely triggered nonsense-mediated decay (NMD). Indeed, we found that only the transcripts from the allele linked with exon skipping showed decreased expression (Fig...
  9. ...presently active mouse endogenous retrotransposons: TF, GF, and A subfamily L1 elements, B1 and B2 SINEs, and IAP and ETn long terminal repeat (LTR) elements (mRC-seq) (Supplemental Fig. S1A; Mager and Stoye 2015; Richardson et al. 2015). We apply this technology to pedigrees of wild-type C57BL/6J mice...
