We talk a lot about mitochondrial stress, but how about how do they keep themselves balanced? Good thing our speaker
@nieminm.bsky.social knows everything about that, and will tell all on the next MITOtalk. Usual time and place. See you there?

Travelling to the future again. This thursday, we will be nosy and learn about mitochondria and their friendships.

Thinking about remodeling? Mitochondria do that too... and our speaker knows all about it.

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.
This thursday, usual time and place. See you there?

MITOchats are all about early career researchers and - of course - mitochondria! Join us tomorrow for three short talks delivered by Julia Riley @joulesriley.bsky.social, Eleonora Stronati, and Joan Blanco-Fernandez @joanblanco.bsky.social. See mitotalks.org for zoom link.

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?

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

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:

MITOtalks and especially MITOchats have been playing with time travel. This week, instead of bringing the future over, we will get there faster: our speaker will tell us all about a mitochondrial progeria syndrome. Usual time and place.
