Isolated Nucleus Stiffens In Response To Low Intensity Vibration, Joshua Newberg
Isolated Nucleus Stiffens In Response To Low Intensity Vibration, Joshua Newberg
Boise State University Theses and Dissertations
The nucleus, central to all cellular activity, relies on both direct mechanical input and its molecular transducers to sense and respond to external mechanical stimuli. This response occurs by regulating intra-nuclear organization that ultimately determines gene expression to control cell function and fate. It has long been known that signals propagate from an extracellular environment to the cytoskeleton and into nucleus (outside-in signaling) to regulate cell behavior. Emerging evidence, however, shows that both the cytoskeleton and the nucleus have inherent abilities to sense and adapt to mechanical force, independent of each other. While it has been shown that isolated nuclei …
