Effects Of Shear Stress On The Distribution Of Kindlins In Endothelial Cells, Sidney V. Jones
Effects Of Shear Stress On The Distribution Of Kindlins In Endothelial Cells, Sidney V. Jones
ETD Archive
Endothelial cells (ECs) are exposed to changes in shear stress under a variety of physiological and pathological circumstances and respond by changing their shape, gene expression and cytoskeletal arrangement. Integrins are central mediators of these mechanotransduction responses of ECs and integrin function is in turn controlled by interaction of their short cytoplasmic tails with cytoplasmic binding partners. Recent studies have demonstrated the importance of the kindlin family members, known cytoplasmic tail binding proteins, as regulators of integrin function. Our lab has previously shown that kindlin-2 (K2) and kindlin-3 (K3) are both expressed and functionally significant for integrin mediated cellular events …

Kindlins are a novel family of cytoskeleton proteins that plays an important role in the activation of heterodimeric integrin transmembrane receptors. These receptors play a vital role in cell adhesion, cell migration and other cellular processes. The Kindlin protein family consists of three homologous proteins, Kindlin 1, 2 and 3 with differential tissue distribution and varying expression levels in human. Mutations of Kindlin 1 protein are clinically linked to Kindler Syndrome. Kindlin 2 knockdown studies have shown embryonic lethality in mouse, but no diseases have been clinically testified. Kindlin 3 mutations are associated with bleeding disorders, e.g. LADIII. Talin is …

Cell functions in multi-cellular organisms are strongly depend on the dynamic cooperation between cell adhesion and cytoskeleton reorganization. Integrins, the major cell adhesion receptors, bind to extracellular matrix (ECM) and soluble ligands on the cell surface and link to the actin cytoskeleton inside the cell membrane. In this manner, integrins integrate cell adhesion and cytoskeleton reorganization by acting as a mechanical force transducer and a biochemical signaling hub (Zamir and Geiger 2001). Consequently, integrins are vital for development, immune responses, leukocyte traffic and hemostasis, and a variety of other cellular and physiological processes. Integrins are also are the focal point …
