Advances in mechanotransduction and sonobiology: effects of audible acoustic waves and low-vibration stimulations on mammalian cells.
Biophys Rev

Department of Optics, Pharmacology and Anatomy, University of Alicante, San Vicente del Raspeig, Spain.
In recent decades, research on mechanotransduction has advanced considerably, focusing on the effects of audible acoustic waves (AAWs) and low-vibration stimulation (LVS), which has propelled the field of sonobiology forward. Taken together, the current evidence demonstrates the influence of these biosignals on key cellular processes, such as growth, differentiation and migration in mammalian cells, emphasizing the determining role of specific physical parameters during stimulation, such as frequency, sound pressure level/amplitude and exposure time. These mechanical waves interact with various cellular elements, including ion channels, primary cilia, cell-cell adhesion receptors, cell-matrix and extracellular matrix proteins, and focal adhesion complexes.

The vascular network, uniquely sensitive to mechanical changes, translates biophysical forces into biochemical signals for vessel function. This process relies on the cell's architectural integrity, enabling uniform responses to physical stimuli. Recently, the nuclear envelope (NE) has emerged as a key regulator of vascular cell function.

Many genes in the human genome encode proteins that are dosage sensitive, meaning they require protein levels within a narrow range to properly execute function. To investigate if clinically relevant variation in protein levels impacts the same downstream pathways in human disease, we generated cell models of two SETBP1 syndromes: Schinzel-Giedion Syndrome (SGS) and SETBP1 haploinsufficiency disease (SHD), where SGS is caused by too much protein, and SHD is caused by not enough SETBP1. Using patient and sex-matched healthy first-degree relatives from both SGS and SHD SETBP1 cases, we assessed how SETBP1 protein dosage affects downstream pathways in human forebrain progenitor cells.

The Linker of Nucleoskeleton and Cytoskeleton (LINC) complex plays a crucial role in connecting the nuclear envelope to the cytoskeleton, providing structural support to the nucleus and facilitating mechanical signaling between the extracellular environment and the nucleus. Research in mechanobiology onboard the International Space Station (ISS) and in simulated microgravity (SMG) highlight the importance of gravity in functional mechanotransduction. Although the altered gravity research regarding mechanobiology has been greatly focused on the cytoskeleton and the extracellular matrix (ECM), recent research demonstrates that SMG also induces changes in nuclear mechanics and gene expression patterns, which have been shown to be LINC complex dependent.

Here we address the role of the NPC in driving thermal stress-induced 3D genome repositioning of ( ) genes in yeast. We found that two nuclear basket proteins, Mlp1 and Nup2, although dispensable for NPC integrity, are required for driving genes into coalesced chromatin clusters, consistent with their strong, heat shock-dependent recruitment to gene regulatory and coding regions.
