In addition to being a major human pathogen, there is burgeoning clinical interest in HSV as a vector in gene delivery and oncolytic therapies, necessitating research into transcriptional control. This review summarizes the array of impacts that HSV has on RNA Polymerase (Pol) II, which transcribes all mRNA in infected cells. We discuss alterations in Pol II holoenzymes, post-translational modifications, and how viral proteins regulate specific activities such as promoter-proximal pausing, splicing, histone repositioning, and termination with respect to host genes. Recent technological innovations that have reshaped our understanding of previous observations are summarized in detail, along with specific research directions and technical considerations for future studies.}, language = {en} } @article{RutkowskiErhardL'Hernaultetal.2015, author = {Rutkowski, Andrzej J. and Erhard, Florian and L'Hernault, Anne and Bonfert, Thomas and Schilhabel, Markus and Crump, Colin and Rosenstiel, Philip and Efstathiou, Stacey and Zimmer, Ralf and Friedel, Caroline C. and D{\"o}lken, Lars}, title = {Widespread disruption of host transcription termination in HSV-1 infection}, series = {Nature Communications}, volume = {6}, journal = {Nature Communications}, number = {7126}, doi = {10.1038/ncomms8126}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-148643}, year = {2015}, abstract = {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 extensive transcription for tens of thousands of nucleotides beyond poly(A) sites and into downstream genes, leading to novel intergenic splicing between exons of neighbouring cellular genes. As a consequence, hundreds of cellular genes seem to be transcriptionally induced but are not translated. In contrast to previous reports, we show that HSV-1 does not inhibit co-transcriptional splicing. Our approach thus substantially advances our understanding of HSV-1 biology and establishes HSV-1 as a model system for studying transcription termination.}, language = {en} }
