Follicular thyroid carcinoma cells treated with rottlerin exhibited decreased protein levels of integrin β1, FAK, and focal adhesion complex components (e.g., vinculin, α-actinin), and reduced activity of GTPases supporting an integrin/focal adhesion/cytoskeleton signaling in the migration arrest induced by rottlerin (27). Here, PTK2 is linked to thyroid gland follicular carcinoma.
