Abstract excerpt
Retinoblastoma cells are resistant to transforming growth factor-beta (TGF-beta) activity due to the absence of TGF-beta binding. To further elucidate the mechanism of TGF-beta resistance, we studied the expression of the TGF-beta receptors and SMADs by using the Y79 and WERI-Rb-1 retinoblastoma cell lines. Binding of 125I-TGF-beta1 to serine/threonine kinase receptor type II (TbetaR-II) and TbetaR-I was not seen...
