Altogether, our results suggest that ZYX defective binding to ACTN4, which occupies focal adhesions instead of ACTN1, induces the formation of immature focal adhesions, resulting in the enhancement of cell motility and invasion.
The Zyxin-related protein thyroid receptor interacting protein 6 (TRIP6) is overexpressed in Ewing's sarcoma and promotes migration, invasion and cell growth.
Knockdown of Zyxin expression by siRNA in fibroblastic type OSCC cells was associated with cell morphological changes from spindle (fibroblastic) to polygonal (epithelial) shape and significantly inhibited cell growth as well as cell migration and invasion.
Functional examination of zyxin by small interfering RNA-mediated knockdown in Hep3B cell line indicated a significant inhibition on cell migration through porous membrane (P = 0.002) and invasion through matrigel-coated membrane (P = 0.005).
