Abstract
As a major co-factor of F-actin depolymerization, WD-repeat domain 1 (WDR1) affects the cellular microenvironment by cytoskeleton remodeling, thereby influencing cell molecular behavior. Our previous study showed that WDR1 activates YAP (Yes-associated protein) signaling in non-small-cell lung cancer (NSCLC) cells, but the mechanism remains unclear. We discovered that knockdown WDR1 in NSCLC cells decreased the expression of YAP and the nucleus-to-cytoplasm ratio. Disruption of cortical stress by drugs significantly inhibited YAP nuclear trafficking and enhanced YAP phosphorylation. In WDR1-knockdown NSCLC cells, inhibition of Hippo pathway reduced the nuclear exclusion of YAP and phosphorylated YAP. Our data suggest that WDR1-mediated cortical stress might be involved in regulating YAP signaling, thereby affecting the proliferation and migration of NSCLC cells.
