Super happy to see this finally out on bioRxiv and to be able to share it! We show that PDHc performs an additional, non-enzymatic function to support mitochondrial DNA gene expression in yeast. Check out the preprint! 🧬👇

Excellent tool! We’ve been testing it all week and it’s already been great for catching every paper. The format makes it much easier to engage with the full daily #mtDNA literature than a standard search! 🧬 Great job @osman-lab.bsky.social

New preprint from my lab!!! We took advantage of the MitoTag mouse line to study what mRNAs associate with mitochondria in axons in vivo, and we were in for a surprise! Other than our favorite Pink1, mainly cytoskeletal mRNAs hitch a ride and pave the way for axon growth. shorturl.at/rYe1U

Mitochondrial hitch-hiking of Mapt mRNA maintains Tau levels in axons
Hitch-hiking of transcripts on organelles, including mitochondria, has emerged as a common pathway to transport mRNAs into the axon to enable their local translation. However, the extent of mitochondr...
