Wide-spread disruption of transcription termination in HSV-1 infection: Next generation sequencing of total and newly transcribed (4sU-RNA) RNA

ABSTRACT: Primary human foreskin fibroblasts (HFF) were infected with wild-type simplex virus 1 (HSV-1) strain 17 at a multiplicity of infection (MOI) of 10. Newly transcribed RNA was labelled by adding 500µM 4-thiouridine (4sU) to the cell culture media for 1h. Total cellular RNA was isolated using Trizol. Newly transcribed RNA was purified following the protocol described in Raedle et al. JoVE 2013. Newly transcribed RNA was labelled in one hour intervals during the first eight hours of HSV-1 infection. All nine 4sU-RNA samples as well as total cellular RNA of every second hour of infection were sent for sequencing. Two independent biological replicates were analysed.

Herpes simplex virus 1 (HSV-1) is an important human pathogen and a paradigm for virus-induced host shut-off. Here we show that global changes in transcription and RNA processing and their impact on translation can be analysed in a single experimental setting by applying 4sU-tagging of newly transcribed RNA and ribosome profiling to lytic HSV-1 infection. Unexpectedly, we find that HSV-1 triggers the disruption of transcription termination of cellular, but not viral, genes. This results in exten ...[more]

Ultra short and progressive 4sU-tagging reveals key characteristics of RNA processing at nucleotide resolution

Project description:RNA synthesis and decay rates determine the steady-state levels of cellular RNAs. Metabolic tagging of newly transcribed RNA by 4-thiouridine (4sU) can reveal the relative contributions of RNA synthesis and decay rates. The kinetics of RNA processing, however, so far remained unresolved. Here, we show that ultra-short 4sU-tagging not only provides snap-shot pictures of eukaryotic gene expression but, when combined with progressive 4sU-tagging and RNA-seq, reveals global RNA processing kinetics at nucleotide resolution. Using this method, we identified classes of rapidly and slowly spliced/degraded introns. Interestingly, each class of splicing kinetics was characterized by a distinct association with intron length, gene length and splice site strength. For a large group of introns, we also observed long lasting retention in the primary transcript, but efficient secondary splicing or degradation at later time points. Finally, we show that processing of most, but not all small nucleolar (sno)RNA-containing introns is remarkably inefficient with the majority of introns being spliced and degraded rather than processed into mature snoRNAs. In summary, our study yields unparalleled insights into the kinetics of RNA processing and provides the tools to study molecular mechanisms of RNA processing and their contribution to the regulation of gene expression. 4sU-tagging was performed in human DG75 B-cells by adding 500 uM 4sU to cell culture medium for 5, 10, 15, 20 or 60 min. Following isolation of total cellular RNA, this was separated into nascent and untagged, pre-existing RNA. Nascent RNA as well as total and untagged RNA from 60 min 4sU-tagging were subjected to SOLiD sequencing (SOLiD II) obtaining 35 nt reads.

4sU metabolic labeled transcripts in 65 YRI LCLs

Project description:Noncoding variants play a central role in the genetics of complex traits, but we still lack a full description of the main molecular pathways through which they act. Here we used molecular data to quantify the contribution of cis-acting genetic effects at each major stage of gene regulation from chromatin to proteins, within a population sample of Yoruba lymphoblastoid cell lines (LCLs). We performed 4sU metabolic labeled transcripts in 65 YRI LCLs to identify genetic variants that affect transcription rates. As expected, we found an important contribution of genetic variation via chromatin, contributing â¼65% of eQTLs (expression Quantitative Trait Loci). The remaining eQTLs, which are not asso- ciated with chromatin-level variation, are highly enriched in transcribed regions, and hence may affect expression through co- or post-transcriptional processes. International HapMap lymphoblastoid cell lines (LCLs) derived from YRI (Yoruba in Ibadan, Nigeria); We adapted the 4sU labelling method from (PMID 21516085). Briefly, cell cultures were grown to log phase in volumes sufficient to yield about 300 ng of 4sU-labeled RNA. Cells were incubated with 4sU for the required length of time (0, 30, or 60 minutes), then washed, pelleted, and frozen. Total RNA was extracted, and 4sU-labeled RNA was separated from total RNA using a bead-based biotin-streptavidin purification protocol. We sequenced metabolic labeled transcripts in 65 YRI LCLs 30 minutes and 60 minutes after incubation.

CRISPR-Cas9 mediated editing of the CD46 gene in primary human B cells prior to their infection with Epstein-Barr virus (EBV) – analysis of CD46 transcripts after 24 hours

Project description:Adenoid B cells from anonymous human donors were isolated and nucleofected with RNP complexes targeting two loci within exon 2 of the CD46 gene, which encodes a cell surface protein. One hour after nucleofection, the same number of control cells (w/o-RNP) and CD46-RNP complex treated cells were infected with Epstein-Barr virus (strain 6008_B95-8) with a multiplicity of infection of 0.1. Newly transcribed RNAs were metabolically labeled with 4-thiouridine (4sU) for 60 min 23 hours after EBV infection. Twenty-four hours after the start of the experiment, 4sU-biotin-labeled, newly transcribed RNAs were thiol-specifically biotinylated and separated from unlabeled RNA using Streptavidin beads. RNA-seq experiments with the enriched RNA samples were performed to analyze the edited CD46 locus encompassing the RNP complex target sites. The experiment revealed that 24 hours after CRISPR-Cas9 mediated gene editing a substantial fraction of CD46 transcript contained indels and a larger deletion in between the two targets sites within exon 2 of CD46.

Transcriptional profiling by 4SU-seq in mouse ESCs and ESC-derived neural progenitor cells.

Project description:Nascent RNA was metabolically labelled with 4SU in undifferentiated and ESC-derived neural progenitor cells (NPCs). 4SU incorporated RNA was isolated and deep-sequenced at day 0 (ESCs), 3, 5 and 7 of differentiation. NPC differentiation was monitored through expression of a GFP reporter insereted into the Sox1 locus (46C reporter ESC line; PMID: 12524553). The aim was to monitor changes in transcription as ESCs differentiate into NPCs and relate this to enhancer activity.
