Transforming growth factor-beta modulates the high-affinity receptors for epidermal growth factor and transforming growth factor-alpha
The epidermal growth factor (EGF) receptor mediates the induction of a transformed phenotype in normal rat kidney (NRK) cells by transforming growth factors (TGFs). The ability of EGF and its analogue TGF-alpha to induce the transformed phenotype in NRK cells is greatly potentiated by TGF-beta, a polypeptide that does not interact directly with binding sites for EGF or TGF-alpha. Our evidence i...
متن کاملEpidermal growth factor and transforming growth factor alpha.
This review describes the discovery and initial characterization of the epidermal growth factors (EGFs) and transforming growth factors alpha (TGF alpha), the biosynthesis and tissue distribution of these molecules and a brief description of the effects of these molecules in culture and animals. An analysis of the similarities between the EGFs and TGF alpha s from different organisms is used to...

متن کاملSynergistic effects of endothelin-1 (ET-1) and transforming growth factor alpha (TGF-alpha) or epidermal growth factor (EGF) on DNA replication and G1 to S phase transition.
The cooperative cell kinetic actions of ET-1 with TGF-alpha or EGF in normal rat kidney fibroblasts (NRK-49F) and KNRK cells (Kirsten MSV transformed) were analyzed by [3H]-thymidine incorporation assay and flow cytometry. A marked synergistic effect of TGF-alpha and ET-1 (or EGF and ET-1) on DNA synthesis and G1 to S transition was observed in NRK cells; 15-20% S for TGF-alpha and 12% S for ET...
متن کاملAnalysis of transforming growth factor (TGF)-alpha/epidermal growth factor receptor, hepatocyte growth Factor/c-met,TGF-beta receptor type II, and p53 expression in human hepatocellular carcinomas.
Experimental data suggest that dysregulation of growth factors and the cognate receptors may play an important role in hepatocarcinogenesis. The objective of the present study was to characterize the expression of two hepatotrophic growth factor/receptor systems [transforming growth factor-alpha/epidermal growth factor receptor (TGF-alpha/EGFR) and hepatocyte growth factor/c-met receptor (HGF/c...
