Wnt pathway negative regulator APC is a Schwann cell tumor suppressor gene and multiple pathways converge downstream resulting in Hippo/YAP activation. (A) Western blot showing loss of APC via CRISPR/Cas9 and increased YAP1 and CTNNB1 levels. (B) Loss of APC results in anchorage-independent growth and cell migration (1.5× magnification). (C) Loss of APC results is tumor formation in NRG xenograft model. (D) Diagram summarizing results showing overall Hippo/YAP activation via the loss of multiple tumor suppressor genes that occur in MPNSTs. Wnt, growth factor activity, cell density and Rho pathway(s) activation results in Hippo/YAP pathway activation in MPNSTs.
