Helping this mood is our latest now out in its final form! @irfankathiriya.bsky.social leading the teams with me. Thanks to the editors and reviewers (incl. @wythelab.bsky.social)for a pleasant and productive journey. More to come when the full issue is out. www.nature.com/articles/s44...

A disrupted compartment boundary underlies abnormal cardiac patterning and congenital heart defects - Nature Cardiovascular Research

Kathiriya et al. identify a cardiac progenitor lineage with expression of Tbx5 and anterior heart field-specific expression of Mef2c that bisects the intraventricular septum during development and sho...

Hiding in plain sight - how close are we to mapping ALL 🧬enhancers🧬 in the genome? Our new paper by Mannion et al. takes a systematic look at "hidden enhancers" and why they remain so hard to find. With @mosterwalder.bsky.social, @jlopezrios.bsky.social & many more www.nature.com/articles/s41...

A busy tool wall in a shed. At the bottom there are instructions saying "Find the 10 hidden enhancers!" Across the wall between the tools are 10 enhancers, represented as DNA helices, but they are difficult to find in the style of a "hidden object" puzzle.

Textbooks: “Enhancers are just a bunch of TFBSs” But how do they REALLY work? New paper with many contributors here @berkeleylab.lbl.gov, @anshulkundaje.bsky.social, @anusri.bsky.social A 🧵 (1/n) Free access link: rdcu.be/erD22

A meme-style comic panel with three parts. Left: A stylized enhancer with a mutation, surrounded by colored blocks representing functional motifs, a neural network diagram, chromatin accessibility signal traces, and a sequence motif. Two cartoon mouse embryos below show different LacZ reporter activity patterns. Top right: A hand hovers anxiously between two red buttons labeled “Experiments” and “AI,” with the caption “HOW DO ENHANCERS REALLY WORK?” Bottom right: A sweating superhero wipes his forehead, looking stressed about the difficult choice.

A dream come true: my first first-author publication! 🧬 🎉 Working to unravel the mysteries of long-range gene regulation has been an incredible journey. Endless gratitude to Evgeny, the lab, and all of the amazing collaborators who helped make this happen 🙌

In this review @gracebower.bsky.social & I discuss recent evidence showing that, unlike canonical enhancers, long-range enhancers located hundreds of kb from their targets rely on additional mechanisms to ensure robust gene activation during mammal development. www.sciencedirect.com/science/arti...
