RhoA, a GTP-binding protein, stimulates the formation of stress fibers, focal adhesions, and tyrosine phosphorylation in quiescent cells. This study shows that rho-induced contractility drives the formation of these structures. Lysophosphatidic acid (LPA) activates rho and induces myosin light chain (MLC) phosphorylation, which precedes the formation of stress fibers and focal adhesions. Inhibiting contractility blocks these events, while stimulating contractility leads to the aggregation of integrins into focal adhesions. Rho activates contractility, which in turn promotes the formation of stress fibers and focal adhesions and increases tyrosine phosphorylation. A model is proposed where contractility promotes these events by driving the assembly of actin filaments and focal adhesions. Tyrosine phosphorylation is a key component of focal adhesions and is stimulated by rho. Inhibitors of contractility, such as BDM, H7, and KT5926, block rho-induced stress fibers, focal adhesions, and tyrosine phosphorylation. These findings suggest that rho-induced contractility is essential for the formation of stress fibers and focal adhesions. The study also shows that contractility modulates the distribution of integrins, with integrins dispersing when contractility is inhibited and aggregating when contractility is stimulated. The results indicate that rho-induced contractility is a critical factor in the formation of stress fibers and focal adhesions.RhoA, a GTP-binding protein, stimulates the formation of stress fibers, focal adhesions, and tyrosine phosphorylation in quiescent cells.
