Dear all, A scientist from UNC Chapel Hill, Paul Maddox, is running for congress in NC for a seat currently held by a republican. If you care about science (and democracy) please consider donating to his campaign #Standupforscience secure.actblue.com/donate/paul-...
Donate to Paul Maddox for Congress in NC 11
Paul is running for Congress because there’s a sickness in Washington, and no one is working to cure it.

These exciting new results therefore have important implications for recoding of the genetic code for synthetic biology purposes and in the use of suppressor tRNAs for premature stop codon readthrough in human diseases. Congrats everyone!

Having a 5 percentile R01 grant not being funded sucks so much. And having it falling through the cracks because of delays in council meetings and other administrative shenanigans even more.

Excited to share this one! We developed an in vivo model for specific manipulation of transfer RNA acetylation and found it serves as a sentinel modification whose loss causes ribosome stalling and stress signaling. Implications for a genetic disorder and cancer.

NIH grants that created genetic medicine cured my hemophilia in 2020. Here is what the 5-years cured blood test looked like last week. Science works! I hope others get the benefits of such research before regressive Republicans send us back to the 19th Century.

Seeing ribosomes in action? Thanks to researchers from the @marvintanenbaum.bsky.social lab this is now possible. They created a technology to track individual ribosomes during mRNA translation. The team found that ribosomes ‘help’ each other in difficult situations www.hubrecht.eu/ribosomes-te...

Are #rRNA #modifications equal a across cell types, conditions and #disease? Are they tuned upon #antibiotics exposure? In our recent works, we find that yes and yes! Exciting times ahead!! Please see authors.elsevier.com/c/1kF253vVUP... and www.nature.com/articles/s41... Feedback very welcome!! :)

Started off this morning emailing my Senators and Congressman about the NIH and the potential damage being done by unnecessary disruptions.

They need to hear from us loud and clear. Constituents matter to them as one of the primary purposes of a politician is to get re-elected (and its their job).

Thrilled to share our latest story identifying TRMT1L as the methyltransferase responsible for the deposition of m22G27 modification on tyrosine tRNAs www.cell.com/cell-reports...
TRMT1L-catalyzed m22G27 on tyrosine tRNA is required for efficient mRNA translation and cell survival under oxidative stress
Hwang et al. identify TRMT1L as the elusive methyltransferase responsible for catalyzing the m22G modification at position 27 on tyrosine tRNA. TRMT1L is also crucial for maintaining acp3U and D modifications on select tRNAs, and its depletion reduces tyrosine tRNA stability, global translation efficiency, and cell survival under oxidative stress.
