- Focusing on something other than Salmonella for a minute, because my wife’s paper is just out and it is AMAZING! www.nature.com/articles/s41... Congrats to all the authors, great work from the @dfachinetti.bsky.social @naltemose.bsky.social labs!
- She worked so incredibly hard for this one and it shows! She showed that DNAme at the centromeres influences CENP-A localisation and centromere function
- Moreover, something we discussed a lot about as it was extremely intriguing at the beginning, it seems that there is a strong level of cellular adaptation when demethylation is slow and gradual vs when it’s fast!
- Anyway, go take a look! There will be some media coverage, I will add to this thread once it’s out!
