Thrilled to announce our #preprint on a new factor in the last line of defense in #translation quality control out on #bioRXiv! Spearheaded by fantastic PhD student @kaushikiyer.bsky.social, supported by Chloé Walter, Alina Kraft, Max Müller and Lena Tittel.

Deep generative models design mRNA sequences with enhanced translational capacity and stability Despite the success of mRNA COVID-19 vaccines, extending this modality to more diseases necessitates substantial enhancements. We present GEMORNA, a generative RNA model that utilizes Transformer arch...

Here, we show that bacterial ribosomes—often viewed as conserved drug targets—actually vary across species due to extensive sequence variation in their drug-binding residues. In some cases, this divergence may lead to intrinsic drug resistance in certain bacterial clades: doi.org/10.1016/j.ce...

I am excited to share the second half of my postdoctoral work in the Yeo lab at UCSD! We found that neuronal aging leads to the accumulation of mitochondrial double-stranded RNA, which triggers the chronic stress response. 1/ www.biorxiv.org/content/10.1...

A rapid, simple, and economical method for the isolation of ribosomes and translational machinery for structural and functional studies Nature Communications - Here, the authors present a method to rapidly isolate actively translating ribosomes in a time- and cost-effective manner using poly-lysine. The method is compatible with a...

Our RAPPL purification of ribosomes and associated material is out. I am really proud of this study in collaboration primary with Pavlovic-Djuranovic lab, as well as Jovanovic and Hashem Labs. This method aims to replace 60 years old purification of ribosomes by sucrose cushions

m6A modification is incorporated into bacterial mRNA without specific functional benefit Abstract. N6-Methyladenosine (m6A), the most abundant modification in eukaryotic messenger RNAs (mRNAs), has also been found at a low level in bacterial mR

Delighted to share our newest publication - beautiful collaboration with Ya-Ming Hou’s lab. If you wonder whether bacterial mRNAs contain m6A (yes they do) and whether it matters (does not seem to) look here 👇🏻

Cells are swapping their mitochondria. What does this mean for our health? Researchers are studying why the energy factories are moving between cells and whether the process can be harnessed to treat cancer and other diseases.

Cells are swapping mitochondria. Wondering whether they also swap much smaller cellular entities, e.g. ribosomes?

Retracted papers had a higher number of self-citations and higher co-authorship numbers - clearly not a causation, but an interesting correlation.
