Here, we unravel the complete viral transcriptome and translatome during lytic infection with base-pair resolution by computational integration of multi-omics data. We identify a total of 201 transcripts and 284 ORFs including all known and 46 novel large ORFs. This includes a so far unknown ORF in the locus deleted in the FDA-approved oncolytic virus Imlygic. Multiple transcript isoforms expressed from individual gene loci explain translation of the vast majority of ORFs as well as N-terminal extensions (NTEs) and truncations. We show that NTEs with non-canonical start codons govern the subcellular protein localization and packaging of key viral regulators and structural proteins. We extend the current nomenclature to include all viral gene products and provide a genome browser that visualizes all the obtained data from whole genome to single-nucleotide resolution. Here, using computational integration of multi-omics data, the authors provide a detailed transcriptome and translatome of herpes simplex virus 1 (HSV-1), including previously unidentified ORFs and N-terminal extensions. The study also provides a HSV-1 genome browser and should be a valuable resource for further research.}, language = {en} } @article{MurakawaHinzMothesetal.2015, author = {Murakawa, Yasuhiro and Hinz, Michael and Mothes, Janina and Schuetz, Anja and Uhl, Michael and Wyler, Emanuel and Yasuda, Tomoharu and Mastrobuoni, Guido and Friedel, Caroline C. and D{\"o}lken, Lars and Kempa, Stefan and Schmidt-Supprian, Marc and Bl{\"u}thgen, Nils and Backofen, Rolf and Heinemann, Udo and Wolf, Jana and Scheidereit, Claus and Landthaler, Markus}, title = {RC3H1 post-transcriptionally regulates A20 mRNA and modulates the activity of the IKK/NF-\(\kappa\)B pathway}, series = {Nature Communications}, volume = {6}, journal = {Nature Communications}, number = {7367}, doi = {10.1038/ncomms8367}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-151596}, year = {2015}, abstract = {The RNA-binding protein RC3H1 (also known as ROQUIN) promotes TNF\(\alpha\) mRNA decay via a 3'UTR constitutive decay element (CDE). Here we applied PAR-CLIP to human RC3H1 to identify ~3,800 mRNA targets with >16,000 binding sites. A large number of sites are distinct from the consensus CDE and revealed a structure-sequence motif with U-rich sequences embedded in hairpins. RC3H1 binds preferentially short-lived and DNA damage-induced mRNAs, indicating a role of this RNA-binding protein in the post-transcriptional regulation of the DNA damage response. Intriguingly, RC3H1 affects expression of the NF-\(\kappa\)B pathway regulators such as I\(\kappa\)B\(\alpha\) and A20. RC3H1 uses ROQ and Zn-finger domains to contact a binding site in the A20 3'UTR, demonstrating a not yet recognized mode of RC3H1 binding. Knockdown of RC3H1 resulted in increased A20 protein expression, thereby interfering with I\(\kappa\)B kinase and NF-\(\kappa\)B activities, demonstrating that RC3H1 can modulate the activity of the IKK/NF-\(\kappa\)B pathway.}, language = {en} } @article{BensaadFavaroLewisetal.2014, author = {Bensaad, Karim and Favaro, Elena and Lewis, Caroline A. and Peck, Barrie and Lord, Simon and Collins, Jennifer M. and Pinnick, Katherine E. and Wigfield, Simon and Buffa, Francesca M. and Li, Ji-Liang and Zhang, Qifeng and Wakelam, Michael J.

In vitro, both were induced by hypoxia in a hypoxia-inducible factor-1 alpha (HIF-1 alpha)-dependent manner. There was a significant lipid droplet (LD) accumulation in hypoxia that was time and O-2 concentration dependent. Knockdown of endogenous expression of FABP3, FABP7, or Adipophilin (an essential LD structural component) significantly impaired LD formation under hypoxia. We showed that LD accumulation is due to FABP3/7-dependent fatty acid uptake while de novo fatty acid synthesis is repressed in hypoxia. We also showed that ATP production occurs via beta-oxidation or glycogen degradation in a cell-type-dependent manner in hypoxia-reoxygenation. Finally, inhibition of lipid storage reduced protection against reactive oxygen species toxicity, decreased the survival of cells subjected to hypoxia-reoxygenation in vitro, and strongly impaired tumorigenesis in vivo.}, language = {en} }
