Tmc1 point mutation affects Ca2+ sensitivity and block by dihydrostreptomycin of the mechanoelectrical transducer current of mouse outer hair cells [PDF]
The transduction of sound into electrical signals depends on mechanically sensitive ion channels in the stereociliary bundle. The molecular composition of this mechanoelectrical transducer (MET) channel is not yet known.

Mechanical stretch scales centriole number to apical area via Piezo1 in multiciliated cells
How cells count and regulate organelle number is a fundamental question in cell biology. For example, most cells restrict centrioles to two in number and assemble one cilium; however, multiciliated cells (MCCs) synthesize hundreds of centrioles to ...

Chondroprotection by urocortin involves blockade of the mechanosensitive ion channel Piezo1 [PDF]
Osteoarthritis (OA) is characterised by progressive destruction of articular cartilage and chondrocyte cell death. Here, we show the expression of the endogenous peptide urocortin1 (Ucn1) and two receptor subtypes, CRF-R1 and CRF-R2, in primary human ...

Pharmacology of PIEZO1 channels
AbstractPIEZO1 is a eukaryotic membrane protein that assembles as trimers to form calcium‐permeable, non‐selective cation channels with exquisite capabilities for mechanical force sensing and transduction of force into effect in diverse cell types that include blood cells, endothelial cells, epithelial cells, fibroblasts and stem cells and diverse ...

Heterologous Expression of the Piezo1-ASIC1 Chimera Induces Mechanosensitive Currents with Properties Distinct from Piezo1 [PDF]
Piezo1 represents a prototype of the mammalian mechanosensitive cation channel, but its molecular mechanism remains elusive. In a recent study, we showed that C-terminal region, which contains the last two TMs, of 2189-2547 of Piezo1 forms the bona fide pore module, and systematically identified the pore-lining helix and key pore-property-determining ...

Plasmodium falciparum ligand binding to erythrocytes induce alterations in deformability essential for invasion [PDF]
The most lethal form of malaria in humans is caused by Plasmodium falciparum. These parasites invade erythrocytes, a complex process involving multiple ligand-receptor interactions.

3D Microfluidic Bone Tumor Microenvironment Comprised of Hydroxyapatite/Fibrin Composite [PDF]
Bone is one of the most common sites of cancer metastasis, as its fertile microenvironment attracts tumor cells. The unique mechanical properties of bone extracellular matrix (ECM), mainly composed of hydroxyapatite (HA) affect a number of cellular ...

Piezo1 activation gains traction
A major unanswered question in biology is how mechanical forces are generated, detected and transduced by cells to impact biochemical and genetic programs. Our work is aimed at uncovering the mechanical principles at play in cells and tissues using novel molecular, imaging and bioengineering tools.
