Project description:Epigenetic control of gene regulation and cell phenotype is influenced by changes in the mechanical microenvironment. Yet how mechanical forces precisely influence epigenetic state to regulate transcriptional responses remains largely unmapped. Here, we combine genome-wide epigenome profiling, epigenome editing, and phenotypic and single-cell RNA-seq screening to identify a sub-class of genomic enhancers that is responsive to the mechanical microenvironment. These enhancers regulate genes that act as key drivers for a variety of functional behaviors including apoptosis, mechanotransduction, proliferation, and migration. We find distinct patterns wherein subsets of mechano-enhancers can be preferentially active on either soft or stiff extracellular matrix (ECM) contexts. Epigenetic editing of these mechano-enhancers on rigid materials precisely tunes mechanically-induced gene expression to levels observed on softer materials, and broadly enables reprogramming of cellular response to the mechanical microenvironment. These mechanically-activated enhancers act as key signal transducers and may constitute a new class of targets that can be modulated to alter mechanically-driven disease states.

Project description:Epigenetic control of cellular transcription and phenotype is influenced by changes in the cellular microenvironment, yet how mechanical cues from these microenvironments precisely influence epigenetic state to regulate transcription remains largely unmapped. Here, we combine genome-wide epigenome profiling, epigenome editing, and phenotypic and single-cell RNA-seq CRISPR screening to identify a new class of genomic enhancers that responds to the mechanical microenvironment. These 'mechanoenhancers' could be active on either soft or stiff extracellular matrix contexts, and regulated transcription to influence critical cell functions including apoptosis, mechanotransduction, proliferation, and migration. Epigenetic editing of mechanoenhancers on rigid materials tuned gene expression to levels observed on softer materials, thereby reprogramming the cellular response to the mechanical microenvironment. These editing approaches may enable the precise alteration of mechanically-driven disease states.
