Now final version out: Our manuscript connecting histone modifications with metabolism: How H4K16 acylations regulate inter +intranucleosomal interactions and confer resilience to metabolic challenges in vivo. Thanks to the team+ @sandrani.bsky.social Enjoy 👇👇 www.cell.com/molecular-ce...

H4K16 acylations destabilize chromatin architecture and facilitate transcriptional response during metabolic perturbations
Nitsch et al. show that short-chain acylations of histone H4K16, acetylation (C2), propionylation (C3), and butyrylation (C4) modulate chromatin structure in vitro. These effects can translate in vivo...

Our new preprint is out: www.biorxiv.org/content/10.6... We show that GRN benchmarks commonly used can overestimate performance due to negative-sampling choices, sometimes allowing simple degree-based baselines to rival more complex GNNs. A reminder of why bias-aware evaluation matters!

Hidden sampling biases inflate performance in gene regulatory network inference

In Xenopus laevis, we found that H3K4 methylation is already laid down at specific loci in gametes and silent early embryos. This pre-marking is essential for accurate zygotic genome activation and proper development.
