Cyclic mechanical strain

WebSep 1, 2004 · Cyclic mechanical strain activates the mitogen-activated protein kinase (MAPK) pathway, promoting cell proliferation. Integrins, which act as mechanoreceptors, may activate MAPK via two major pathways, one involving focal adhesion kinase (FAK) and the other, the protein Shc. In contrast to cultured cells, exposure of intact aortas in … WebApr 2, 2024 · In the lungs, vascular endothelial cells experience cyclic mechanical strain resulting from rhythmic breathing motions and intraluminal blood pressure. Mechanical stress creates evident physiological, morphological, biochemical, and gene expression changes in vascular endothelial cells.

WebMay 11, 2009 · The effects of cyclic strain on VSMC migration and the mechanisms involved are poorly understood. Application of 20% strain to cultured VSMCs enhances VSMC migration (Li et al., 2003), which suggests that mechanical strain has a modulating effect on VSMC migration. Our study showed that 10% strain inhibited VSMC migration. cee recrutement thouars https://jackiedennis.com
