A major output of the 4D Nucleome project appeared today. This is the joint effort of many scientists working together and (publicly) sharing data and results for several years. We hope this is of interest to many genome biologists! www.nature.com/articles/s41...

An integrated view of the structure and function of the human 4D nucleome - Nature

The 4D Nucleome Project demonstrates the use of genomic assays and computational methods to measure genome folding and then predict genomic structure from DNA sequence, facilitatin...

In this episode we talked with @andersshansen.bsky.social from MIT about his work on the impact of 3D genome structures on gene expression and advanced techniques like Region Capture Micro-C for mapping genome organisation. #podcast #epigenetics Listen here: activemotif.com/podcasts-and...

Excited that our paper was published in Science Advances 🧪 Great work by first author Merrick Pierson Smela who will carry this work forward in his new start-up!

Wyss researchers have induced human stem cells to initiate meiosis – a key step in creating eggs and sperm – in the lab for the first time. This work was published in @science.org Advances.

New preprint from @apombo1.bsky.social’s lab on gene regulation; insights into super-enhancers and their role in establishing complex regulatory networks of cell-type specific interactions with other enhancers and genes with specialized cellular functions 🧪🧬 www.biorxiv.org/content/10.1...

Specialised super-enhancer networks in stem cells and neurons

Super-enhancers (SEs) are clusters of enhancers with high transcriptional activity that play essential roles in defining cell identity through regulation of nearby genes. SEs preferentially form multi...

(1/n) DNA-PAINT imaging inside the nucleus at single antibody resolution using TIRF? Ultrathin sectioning makes it happen! Grateful to share my postdoctoral work introducing “tomographic & kinetically-enhanced DNA-PAINT” or in brief: tkPAINT. Out in @pnas.org! doi.org/10.1073/pnas... 👇🧵

🚨New preprint from the lab🚨 🧬 What keeps certain chromatin domains anchored at the nuclear periphery? Our new genome-wide HiDRO screen uncovers a key role for RNA-binding protein hnRNPK. www.biorxiv.org/content/10.1...

Mechanistic and Epigenetic Partitioning of Lamina-Associated Chromatin Revealed by a Genome-Wide Imaging Screen

The nuclear periphery is a key site for heterochromatin organization in eukaryotic cells, where lamina-associated domains (LADs) promote transcriptional repression and genome stability. Despite their ...
