Effect of chronic mechanical compression on immortalized human astrocytes


ABSTRACT: Immortalized human astrocytes were subjected to a controlled in vitro model of chronic mechanical compression to investigate how solid stress—similar to that exerted by growing brain tumors—directly affects astrocyte transcriptional programs. RNA sequencing was performed after 24 hours of compression to measure sustained mechanotransductive responses. Compressed astrocytes showed robust induction of AP-1-associated immediate-early genes and activation of NF-κB–dependent inflammatory pathways. These data define the transcriptional signatures by which human astrocytes detect and respond to mechanical stress, providing a resource for understanding mechanobiology and neuroinflammatory signaling in diseases featuring mass effect, including glioblastoma and traumatic brain injury.
