Very excited to see the first Beisaw lab publication out in its final form 🥳🥳 rdcu.be/ei1I7 if you’re interested in zebrafish heart regeneration and how cardiomyocytes replace the fibrotic injured tissue (spoiler alert: macrophages play an important role), then read it here 👇
From our colleagues down the hall 🥳 cardiac epigenome review 🧬
New online! Cardiac epigenome in heart development and disease #CardioSky
Cardiac epigenome in heart development and disease
Nature Reviews Cardiology, Published online: 02 January 2026; doi:10.1038/s41569-025-01223-1In this Review, Laurette and Gilsbach summarize the current knowledge on the cardiac epigenome, including the dynamic changes in DNA methylation, histone modifications and chromatin accessibility in cardiomyocytes during development and disease. They also describe the interplay between cell type-specific mechanisms and discuss the translational potential of targeting epigenetic mechanisms for the prevention and treatment of cardiac diseases.

I promise we will be grateful rather than annoyed. My email inbox is a disaster and I’m quite junior - and very few of us have secretarial support
