  1. ...dosage sensitive. Studying cells of individuals with sex chromosome aneuploidy, we observe that when the number of Y Chromosomes increases, DDX3X transcript levels fall; conversely, when the number of X Chromosomes increases, DDX3Y transcript levels fall. In 46,XY cells, CRISPRi knockdown of either DDX3X...
  2. ...-based transcriptional regulatory networks. Overall, these results illustrate the power of an approach combining genetic perturbation with high-resolution epigenomic profiling; the latter enables a close examination of the interplay between TFs and nucleosomes -wide, providing a deeper, more mechanistic understanding...
  3. ...Regulated post-transcriptional RNA cleavage diversifies the eukaryotic transcriptome Tim R. Mercer 1 , 4 , Marcel E. Dinger 1 , 4 , Cameron P. Bracken 2 , 3 , Gabriel Kolle 1 , Jan M. Szubert 2 , Darren J. Korbie 1...
  4. ...suggest multiple enzymes affect the post-transcriptional modification of miRNAs by 39 NTA. To validate the accuracy of the assays in Figure 7B, we tested the ability of our adapted nCounter miRNA variant profiling assay Figure 5. Development of the nCounter miRNA assay to detect miRNA 39 variants. (A...
  5. ...Fig. S1A), we hypothesized that repetitiveness may correlate with transcriptional silencing by DNA methylation. We profiled mCG levels in gene bodies and observed that, although the majority of genes displayed very low mCG levels, 18% of all R. irregularis genes are highly methylated (Fig. 3A...
  6. ...that departures from the normal cellular composition correlate with histological phenotypes associated with disease.Transcriptional profiles reflect cell type, condition, and function. In tissues and organs, they are monitored in RNA extracted from millions to billions of cells (116–109) (Haque et al. 2017...
  7. ..., hinging on the precise binding of transcription factors (TFs) and cofactors to gene regulatory elements such as promoters and enhancers. Although it is relatively routine to profile -wide DNA binding landscapes of proteins, identifying the specific proteins that bind to, and regulate the transcription of...

  8. ...and avian sex chromosomes and reveal an important role for post-transcriptional regulatory sequences (miRNA target sites) in sex chromosome evolution.The mammalian X and Y Chromosomes evolved from a pair of ordinary autosomes over the past 300 myr (Lahn and Page 1999). Only 3% of genes on the ancestral pair...
  9. ...(Lelli et al. 2012). Similarly, Plasmodium differentiation and growth within various cell types and hosts involves complex regulatory mechanisms that govern both transcriptional and post-transcriptional processes (Hughes et al. 2010; Cui et al. 2015; Vembar et al. 2016). Development during the IDC...
  10. ...are fundamentally limited in temporal resolution owing to the substantial lag between changes in transcriptional activity and detectable changes in the level of mRNAs. This lag results in part from the time required for transcription and post-transcriptional processing, and in part because pre-existing mRNAs buffer...
