sADAM33 overexpression enhances the stiffness, traction force and contractility of ASMCs.
sADAM33 overexpression promotes a hypercontractile phenotype of ASMCs.
The hypercontractile phenotype transition was largely mediated via Rho/ROCK pathway.
ADAM33 knock-down had little effect on the stiffness, traction force and contractility of ASMCs.
