In support of this, overexpression of TrkB-T1 but not a TrkB-T1 COOH-terminal deletion mutant in nonmetastatic pancreatic cancer cells was shown to induce liver metastasis in an orthotopic xenograft mouse model of pancreatic cancer by sequestering Rho GDP dissociation inhibitor and promoting RhoA activation [69]. The gene discussed is NTRK2; the disease is pancreatic neoplasm.
