New preprint from Shendure Lab on Locus-Scale aka Long-@$$ MPRAs led by the amazing Abby McGee & @carinabiar.bsky.social Most MPRAs test ~300 bp fragments next to a promoter. But real enhancers are bigger, act combinatorially and from a distance. 1/n www.biorxiv.org/content/10.6...

RNA-seq tells us how much RNA is present in the cell. But to understand gene regulation, we need to easily measure the synthesis and decay rates driving this abundance. We introduce AIR-seq: analog intrinsic recoding sequencing. (1/6) www.biorxiv.org/content/10.6...

Excited to share a preprint which is currently under revision! Together with the amazing @ymzhan.bsky.social in @patrick-cramer.maxplanck.de lab, we describe that the +1 nucleosome actively regulates the transition from transcription initiation to elongation www.biorxiv.org/content/10.6... 1/

Thank you Broad Institute of MIT and Harvard for this profile. The last 2 years have been an extraordinary moment of creativity and inspiration. If you’re interested in joining us, PM me! We’re building new methods, models and ML tools - we’re recruiting at all levels!

Shaped by a tumultuous childhood, Broad researcher and epigenomic tool-maker @jbuenrostro.bsky.social pivots to studying the biology of stress and adversity and finding new ways to boost resilience.

Out today in PNAS: We show that dynamic "4D" forces can spatially pattern angiogenesis in a PIEZO1-dependent manner. Excitingly, changing force patterns over time enables redirecting sprouting trajectories, forming complex branched geometries: www.pnas.org/doi/10.1073/... #TissueEngineering

Very excited to share our new Nature study! We discovered that replication stress stabilizes CTCF-dependent chromatin loops enclosing stressed nascent DNA, where G9a-mediated heterochromatin protects it from nucleolytic degradation. rdcu.be/frzLg Huge thanks to all our collaborators and co-authors!

Minibwa is a hybrid of bwa-mem and minimap2 and the successor of bwa-mem for short-read mapping. ~4X/2.5X as fast as bwa-mem/bwa-mem2 for WGS reads at comparable accuracy. Native support of directional bisulfite-seq. Applicable to long reads. Preprint at arxiv.org/abs/2606.15357

Excited to share the first pre-print from our lab!! Check it out here! www.biorxiv.org/content/10.6... We found that many RNA-binding proteins canonically understood to regulate RNA processing can also function like transcription factors and cofactors to directly regulate transcription.

Exciting breakthrough technology from the lab, now live in @cellcellpress.bsky.social ! Instead of cutting the genome where proteins bind (e.g., Cut&Tag), D&D-seq scars the DNA with a deaminase, allowing single cell genome mapping of TFs and chromatin remodellers!

Why can't we explain enhancer action despite 2 decades of chromosome conformation technologies? 😬 Our new study spearheaded by Leonid Mirny's group points to a flaw in our assumptions, and to a solution from physical principles By @timothyfoldes.bsky.social 💻& @karissalhansen.bsky.social 🧪 🧵👇

Excited to share our new study on CpG islands (CGIs) regulation by transcription factors (TFs)! CGIs drive most transcription initiation with unclear regulation. We find that chromatin-opening TFs are key players—following a surprisingly simple rule. 🧵 www.biorxiv.org/content/10.6... 1/9
