Single-cell multi-omic detection of DNA methylation and histone modifications reconstructs the dynamics of epigenomic maintenance - Nature Methods

This work presents scEpi2-seq, a method for simultaneous single-cell profiling of DNA methylation and histone modifications, enabling direct investigation of the interplay between these two epigenomic marks.

nature.com

🧬 Hubrecht researchers have developed a method that can detect DNA methylation and histone modifications simultaneously in single cells. They can now for the first time study how their interaction influences gene activity. https://www.nature.com/articles/s41592-025-02847-4  @jervdberg.bsky.social

New method 🚀: scEpi2-seq lets us read DNA methylation+histone marks in the same single cell. Found that methylation “memory” after replication depends on chromatin+histones, and TF promoters repressed by H3K27me3 carry distinct methylation. So stoked to share this as first+co-corresponding author 🎉

RNA transcripts regulate G-quadruplex landscapes through G-loop formation

G-quadruplexes (G4s) are prevalent DNA structures that regulate transcription but also threaten genome stability. How G4 dynamics are controlled remains poorly understood. Here, we report that RNA tra...

science.org

We found G4s are recognized as DNA lesions leading to homology-directed invasion of RNA opposite the G4 to form a G-loop structure. This G-loop initiates G4 unwinding by DHX36 and FANCJ. Subsequent nucleolytic incision followed by renewal of the RNA-containing strand drive G-loop disassembly (2/4)

Inhibition of this mechanism causes global G4 and R-loop accumulation, leading to transcription dysregulation, replication stress, and genome instability. Thanks to cells from @joost84.bsky.social from the Tijsterman lab and amazing scEdUseq by @jervdberg.bsky.social from the Oudenaarden lab (3/4)
