Inhibition of Cellular Proliferation by the Wilms’ Tumor Suppressor WT1 Is Associated with Suppression of Insulin-Like Growth Factor I Receptor Gene Expression
1 Jul 1995
Abstract excerpt
We have investigated the regulation of the insulin-like growth factor I receptor (IGF-I-R) gene promoter by the Wilms' tumor suppressor WT1 in intact cells. The levels of endogenous IGF-I-R mRNA and the activity of IGF-I-R gene promoter fragments in luciferase reporter constructs were found to be significantly higher in G401 cells (a Wilms' tumor-derived cell line lacking detectable WT1 mRNA) than in 293 cells (a...
