Are weak TF motifs important? Weilert et al use deep learning to systematically map low-affinity pioneer binding sites in mESCs and show that they cooperate with strong pioneer motifs to drive chromatin opening.

🧬🔬 Why are enhancers transcribed and how does that impact gene regulation? I’m really excited to share our new paper in @science.org showing that noncoding RNAs control the timing of gene activation in embryos. With Mike Levine #ScienceResearch @columbiamed.bsky.social A few highlights below... 🧵👇
Noncoding transcription controls the developmental dynamics of long-range gene regulation
The genomic regions regulating gene expression are often themselves transcribed into a variety of noncoding RNAs (ncRNAs). However, the regulatory roles of this noncoding transcription remain largely ...

Have you ever wondered why developmental genes are often regulated by enhancers located at long distances? In this @natgenet.nature.com perspective, we speculate that long-range enhancer positioning may provide regulatory properties essential for proper gene expression www.nature.com/articles/s41...

Alterations in chromatin organization promote totipotent-like features in a DPPA2/DUX-dependent manner - The EMBO Journal

In a new (ish) preprint, we used CRISPR barcodes to label germline stem cell clones in zebrafish, then tracked their contributions to sperm production for 2 years. Instead of staying stable, individual clones rose, fell, and disappeared over time. www.biorxiv.org/content/10.6...
Clonal dynamics deviate from neutral drift in zebrafish spermatogenesis
Spermatogonial stem cells (SSCs) maintain male fertility, but how their clonal dynamics change with age remains poorly understood. Here, we use in vivo CRISPR barcoding in zebrafish to label SSCs and ...
