摘要: Inactivation of the von Hippel-Lindau protein (pVHL) has been implicated in pathogenesis renal carcinomas and central nervous system hemangioblastomas. These are highly vascular tumors which overproduce angiogenic peptides such as endothelial growth factor/vascular permeability factor (VEGF/VPF). Renal carcinoma cells lacking wild-type pVHL were found to produce mRNAs encoding VEGF/VPF, glucose transporter GLUT1, platelet-derived B chain under both normoxic hypoxic conditions. Reintroduction wild-type, but not mutant, into these specifically inhibited production conditions, thus restoring their previously described hypoxia-inducible profile. Thus, appears play a critical role transduction signals generated by changes ambient oxygen tension.
