Chemical and mechanical stimuli act on common signal transduction and cytoskeletal networks #MMPMID27821730

Cells directionally migrate in response to a variety of external cues, including chemical, electrical, and mechanical stimuli; however, only response to chemoattractants has been characterized at the molecular level. Binding of chemoattractants to specific surface receptors triggers rapid, transient activation of many signal transduction and cytoskeletal events. We discovered that brief application of shear stress to cells likely elicits activation of all of the same events. Responses to chemoattractants and shear stress are susceptible to many of the same perturbations, although that to mechanical stimulation uniquely is blocked by disruption of the actin cytoskeleton. Our finding provides insight into the molecular mechanism of cellular response to mechanical stimuli and has important implications for integration of chemical and mechanical inputs.
