Cellular responses rely on effective sensing and intra-cellular transduction of environmental information. This information is either coded in the extracellular matrix as biochemical cues or activated by mechanosensitive signaling cascades through dynamic environmental force gradients. The nucleus, a mechanically-integrated mechanosignaling center, utilizes both direct mechanical input as well as its molecular transducers to sense external stimuli. Fueled by the state-of-the-art molecular, computational and experimental approaches, we are beginning to understand how nucleus structure and connectivity can serve as a mechanosensory element in cells. Cytoskeletal and externally applied forces in turn, initiate mechanosignaling and restructuring events at the nuclear envelope and nucleoskeleton via utilizing chromatin and actin toolboxes. In this way, nuclear mechanotransduction events provide a framework by which chromatin is organized during development, disease and regeneration.
The nuclear envelope, nucleoskeleton and nuclear actin are emerging as critical signaling elements that dynamically regulate how physical information from the extracellular matrix is transduced into the nucleus, affecting nuclear mechanics, conformational changes in nuclear lamina, chromatin organization, DNA repair. Furthermore, mechanotransduction or structural disorders observed in diseases such as cancer, Emery-Dreifuss muscular dystrophies and progeria correlate with mutations in nuclear mechanobiology elements including but not limited to and chromatin dynamics are less understood. Therefore, careful, multidisciplinary studies of extra-nuclear and intra-nuclear mechanotransduction events are needed to shed light into this emerging field of investigation.
A more complete understanding of nuclear organization, signaling, mechanics and chromatin dynamics cannot be gained without uncovering the role mechanical forces play in these processes. This Article Collection welcomes Original Research, Short Reports, and Review manuscripts focused on characterizing and defining roles of mechanical forces in regulation of nuclear mechanotransduction events. In addition, Method manuscripts aimed at quantifying the mechanical forces and understanding the interactions and functions mechanical forces within the nuclear environment are within the scope of the call. This Article Collection aims to bring together multidisciplinary studies to understand how mechanical forces regulate nuclear function.
