Inhibition of focal adhesion kinase impairs tumor formation and preserves hearing in a murine model of NF2-related schwannomatosis.

ABSTRACT: NF2 (neurofibromatosis type 2)-related schwannomatosis (NF2-SWN) is a cancer predisposition syndrome characterized by the development of bilateral vestibular (VS) and spinal schwannomas. While benign, these tumors can cause substantial morbidity, and effective pharmacological treatments remain limited. Here, we demonstrate that genetic ablation of focal adhesion kinase (Fak/Ptk2) impairs tumor formation and preserves hearing in a murine model of NF2. Mechanistically, we show that Fak deletion decreases macrophage infiltration, attenuates nucleotide-binding oligomerization domain-containing protein 2-, leucine rich repeats (LRR)- and pyrin domain-containing protein 3 inflammasome activation, and suppresses the hepatocyte growth factor-MET axis.
