Evolution of Single-Cell 3D Genomes in Kras-Driven Cancers

This study uses in situ single-cell chromatin tracing to map 3D genome changes during Kras-driven lung and pancreatic cancers, revealing stage-specific conformational alterations that can distinguish cancer states, identify prognostic genes, and uncover regulators like Rnf2 that influence genome architecture and tumor progression.

3D Organization of Active and Silenced E. coli Genome

The study uses ultra-high-resolution Micro-C mapping to reveal complex 3D structures in the E. coli genome, including transcription-dependent domains called OPCIDs and repressive structures called CHINs and CHIDs, which are primarily assembled on horizontally transferred genes and regulated by nucleoid-associated proteins like H-NS. These structures influence gene expression and genome stability, with H-NS playing a central role in their formation and maintenance.
