Do zebrafish regenerate their hearts equally? In our new paper at the @tillymommersteeg.bsky.social lab we uncovered variations in the regenerative response of 7 wt zebrafish strains leading us to identify a critical role of oxidative phosphorylation in long-term heart regeneration.

Thank you Prof Noble for giving an astonishing lecture yesterday @oxforddpag.bsky.social! We hope you enjoyed this precious opportunity to discuss with Prof Noble.

Next we will have Dr. Xin Zhou on June 17th at 4PM. Stay tuned!

Our first seminar of the term will be delivered by Prof Denis Noble on "The pacemaker channels of the heart: from reductionism to systems biology" this week, on Wednesday the 4th of June at 4pm at the Sherrington Library. As always, a drinks reception will follow for discussion.

Excited to share our preprint! We show that sustained macrophage and B cell responses are essential for heart regeneration in Mexican cavefish, helping uncover why surface fish heal but cavefish scar 🫀🐟. Check out the full story:

Absence of a prolonged macrophage and B cell response inhibits heart regeneration in the Mexican cavefish
A balanced immune response after cardiac injury is crucial to successful heart regeneration, but knowledge of what distinguishes a regenerative from a scarring response is still limited. The Mexican c...

Additionally, we aim to connect students with an interest in the heart sciences through social events. We also organise outreach activities in order to promote awareness for the cardiac sciences in the wider community.

Paper alert! Congrats to Lara, @cmdooley.bsky.social , @douglasadamoski.bsky.social and Thomas Juan for their great work on identifying the first example of Transcriptional Adaption in humans!🎉
1/? 🧬 New Breakthrough in Duchenne Muscular Dystrophy (DMD)!
Our new paper in
@Nature
reveals how utrophin—a dystrophin “backup”—is upregulated in DMD. The key? Transcriptional adaptation (TA), triggered by mutant mRNA decay, not protein loss.
