ARPC1A and Wiskott-Aldrich syndrome: Similarly, several members of this actin-related protein complex (ARPC1a, 3, 4, 5) and the Wiskott-Aldrich syndrome (WAS)-related proteins (WASp, WAS, WASI) were enhanced upon gas plasma treatment on d6 (Fig. S2e), suggesting cellular protrusion formation with dynamic regulation of an actin assembly/disassembly supported cell migration.
