Super excited to share my postdoctoral work at @imbavienna.bsky.social @viennabiocenter.bsky.social - We discovered that some retrotransposons, or "jumping genes" 🧬, are able to spread from cell to cell via a new viral infectivity route. A short thread: 🧵👇 (1/7)

Happy to share the first preprint out of the Nomburg lab! Many aspects of cellular immunity are shared across the tree of life. Here, we show that some of these conserved aspects of cellular immunity are mirrored by conserved effectors of immune antagonism. Thread below! 1/15

Our paper out in Science today: The Metis defense system senses molecular byproducts released when a phage degrades the bacterial genome, and then prevents replication of the phage in the infected cell Congratulations @ostermanilya.bsky.social and co-authors!

Bacteria sense virus-induced genome degradation via methylated mononucleotides
Phages often degrade the genome of their bacterial host to individual nucleotides. Here we describe Metis, a bacterial defense system that directly senses phage-mediated host genome degradation. Metis...

Our evil ORFeome paper is out! In collaboration with @alex-stark.bsky.social, we screened ~4,000 viral proteins and secreted effectors from bacteria and parasites, covering hundreds of diverse pathogens, for phenotypes in human cells.

Now out @natbiotech.nature.com ! Do lncRNAs commonly bind 1000s of genomic sites? Maybe they do, but the dozens of studies that report genomic binding maps of lncRNAs are deeply flawed, with probes binding suprious DNA sites rather than RNA-bound ones.

Despite EVERYTHING, we're still on for our annual Nucleic Acids Therapeutics next week at the Weizmann! There are still places to register (for free!), link in the first comment. Looking forward to meeting friends, great science, deep discussions, and great food, as always :-)

Overall, our study demonstrates that RNA2.7 reshapes RNA biology in the infected cell, sequestering RBPs and modifying RNA stability. Functionally it contributes to the fascinating and complex cell cycle arrest phenotype mediated by HCMV and is important for the infection of rapidly cycling cells.

RNA2.7 alone is sufficient for inducing a cell cycle arrest, even outside of the context of infection. A tiled screen discovered an adenine-rich region which is required for this function.

Knockout of RNA2.7-bound RBPs induces a cell cycle arrest and partially rescues the ΔRNA2.7 infection. This suggests that RBP sequestration plays a part in RNA2.7’s functionality.

Functionally, RNA2.7 is required for arresting the cell cycle of G1-infected cells and for promoting their infection. Interestingly, cells infected at G0 are unaffected by RNA2.7, highlighting its specific role in the infection of actively cycling cells.

RNA2.7 pulldown identified binding to RNA-binding proteins (RBPs). eCLIP data further show that these RBPs are enriched on transcripts upregulated in an RNA2.7-dependent manner.

RNA2.7 expression reshapes the host transcriptome, and these effects strongly correlate with changes in RNA stability, indicating that altered stability drives cellular RNA abundance.

RNA2.7 accumulates in the cytosol and is the most abundant polyadenylated transcript in infected cells. To dissect its function, we utilized a deletion mutant virus (ΔRNA2.7) and examined its impact on host mRNAs.

Tomorrow at the #SystemsVirologyJournalClub, @finkelyaara.bsky.social will present her work with @sginossarlab.bsky.social on engineering HCMV to express sgRNA libraries directly from the viral genome to profile virus-host interactions across the infection cycle. Join us!

Our new paper is out in Nature 🎉. We show that m1Ψ in mRNA vaccines doesn’t just quiet immunity, it also directly enhance translation by reshaping ribosome dynamics in a sequence-dependent way 🧬 Full paper : rdcu.be/eY5gx

1/ Transposable elements are often called "jumping genes" because they mobilize within genomes. 🧬 But did you know they can also jump 𝘣𝘦𝘵𝘸𝘦𝘦𝘯 cells? 🤯 Our new study reveals how retrotransposons invade the germline directly from somatic cells. www.biorxiv.org/content/10.1... A short thread 🧵👇
