1 Inhibition of prostatic tumor cell proliferation by suramin: alterations in TGF alpha-mediated autocrine growth regulation and cell cycle distribution. Suramin transforming growth factor alpha Homo sapiens
2 The present studies were designed to evaluate the ability of suramin to inhibit PC3 and DU145 proliferation by interfering with TGFa-mediated autocrine growth. Suramin transforming growth factor alpha Homo sapiens
3 Suramin also interfered with TGFa-mediated growth mechanisms. Suramin transforming growth factor alpha Homo sapiens
4 Specifically, suramin reduced the specific binding of TGFa to PC3 and DU145 cells. Suramin transforming growth factor alpha Homo sapiens
5 Additionally, the inhibitory effect of suramin on DU145 was reversed by cultivation of cells in the presence of excess TGFa. Suramin transforming growth factor alpha Homo sapiens
6 These studies show that the inhibitory effect of suramin on PC3 and DU145 cell growth is mediated, in part, by alteration of TGFa-mediated autocrine growth mechanisms and cell cycle kinetics. Suramin transforming growth factor alpha Homo sapiens
