5 years of MITOtalks!

Feels like it was yesterday when @wanrooij20.bsky.social
and @nunoraimundo.bsky.social
opened the first MITOtalk to introduce
@frezzalab.bsky.social.

But it turns out FIVE YEARS have passed. That's 57 MITOtalks, 44 MITOchats, 6000+ followers.

Onwards and upwards!

In case you overloaded mitochondria and peroxisomes during your holidays, know that they are talking about it... and our speaker Peter Kim overheard the conversation.

How's your juggling act? Mitochondria also have one, and the MITOtalk this week will be all about it.

Our new preprint is out 🥳🥳🥳

Henipaviruses, like Nipah and Hendra, package their genomes inside helical shells built by thousands of nucleoproteins. These nucleocapsids are essential to protect the viral RNA, but how do they ever let the polymerase in to read the sequence?

Who wouldn't want a good workout for their mitochondria to be fit?? Learn with our speaker Kostas Tokatlidis how to get them fit!
We would tell you the time and place, but you know where to find this MITOtalk on October 2nd. Right?

Our newest paper on mitochondrial Topoisomerase 1 shows that Top1mt has only weak endoribonuclease activity and it therefore does not often generate deletions at incorporated ribonucleotides. This helps explain why ribonucleotides are tolerated in mtDNA. Read more:

The low endoribonuclease activity and lack of rNMP preference of human mitochondrial topoisomerase 1 protect against ribonucleotide-dependent deletions
Abstract. The incorporation of ribonucleotides (rNMPs) into the nuclear genome leads to severe genomic instability, including strand breaks and short 2–5 b
