A "Patient-Like" Orthotopic Syngeneic Mouse Model of Hepatocellular Carcinoma Metastasis
Published on: October 24, 2015
Abstract:
A case of pure carcinoid of the testis is reported. The patient presented with metastatic carcinoid and the carcinoid syndrome 17 years after removal of the primary tumor. He died 2 years later. The long interval from initial orchiectomy to presentation with metastases strongly suggests that the original lesion was primary rather than metastatic. Only 2 cases have been reported to date in which an apparently pure primary testicular carcinoid developed metastases. In both of these cases the possibility that the testicular lesion itself was metastatic was not excluded.

Epithelial-to-Mesenchymal Transition
The epithelial-to-mesenchymal transition or EMT is a developmental process commonly observed in wound healing, embryogenesis, and cancer metastasis. EMT is induced by transforming growth factor-beta (TGF-β) or receptor tyrosine kinase (RTK) ligands, which further...
