The nucleus spatially partitions mechanoprotection and mechanosensing

Mechanically induced chromatin accessibility and transcription during EMT are spatially patterned in the nucleus, with genes nearest deformations showing protection linked to chromatin closure.

• Why it matters: It remains unclear how the nucleus simultaneously protects the genome and senses mechanical forces, especially during EMT where transcriptional programs shift.
• What they did: The authors combined genome-wide analyses with in vivo nuclear micromanipulation and quantitative live imaging to map transcriptional responses to force across nuclear space.
• The result: They show that moving a gene between chromatin environments changes its mechanosensitivity, implying mechanosensing depends on chromatin context rather than fixed force sensitivity.
