How does PIEZO1 regulate cell glycolysis? what is the molecular mechanism?
10 answers
PIEZO1, a mechanosensitive ion channel, plays a pivotal role in regulating cellular glycolysis through a series of molecular mechanisms that involve calcium signaling and subsequent activation of cellular pathways. The activation of PIEZO1 by mechanical stimuli such as altered microenvironmental stiffness or mechanical stretch leads to an increase in intracellular calcium levels. This calcium influx is crucial for the activation of the CaMKII-HIF1α axis, which in turn promotes aerobic glycolysis. The process of aerobic glycolysis is essential for fulfilling the energetic and biosynthetic demands of cells during various physiological and pathological processes. Moreover, PIEZO1's role in mitochondrial function further elucidates its involvement in cellular energy metabolism. The activation of PIEZO1 induces mitochondrial calcium uptake and enhances oxidative phosphorylation (OXPHOS), thereby increasing the mitochondrial oxygen consumption rate (OCR) and adenosine triphosphate (ATP) production. This suggests that PIEZO1 not only influences glycolysis but also impacts the overall energy metabolism of the cell by modulating mitochondrial activity. The regulation of PIEZO1 itself is complex and involves its interaction with the plasma membrane, cytoskeleton, and extracellular matrix (ECM), which can affect its properties and, consequently, its role in glycolysis. Additionally, the mechanotransductive release of ATP from cells, as regulated by PIEZO1, indicates its broader involvement in cellular energy dynamics. In summary, PIEZO1 regulates cell glycolysis through a molecular mechanism that involves the mechanosensitive activation of the channel, leading to calcium influx. This calcium signaling activates the CaMKII-HIF1α axis to promote aerobic glycolysis, while also enhancing mitochondrial function and ATP production. Through these pathways, PIEZO1 plays a critical role in the metabolic adaptation of cells to mechanical stimuli and changes in their microenvironment.

Does isometric contraction promote tissue regeneration and healing in injured muscles?
5 answers
Isometric contractions have shown varying effects on tissue regeneration and healing in injured muscles. Research indicates that isometric contractions do not generate more reactive oxygen species (ROS) compared to lengthening contractions, suggesting that ROS may not be the initiating signals for regenerative processes. However, post-injury stretch following muscle injury induced by lengthening contractions has been found to facilitate regeneration and promote structural and functional recovery, leading to faster recovery of muscle torque and myofiber size. On the other hand, complete spinal cord injury (SCI) subjects have shown increased susceptibility to muscle damage during isometric contractions, indicating that affected muscles post-SCI are more prone to contraction-induced injury compared to able-bodied controls. Therefore, while isometric contractions may not directly initiate regenerative processes, they can play a role in facilitating recovery and promoting muscle healing post-injury.
