1 Competitive quantitative RT-PCR demonstrated that the level of TGF-beta1 messenger RNA increased approximately 7-fold when cells were treated with 10(-7) M DHT. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
2 Results of Western blot analysis showed a dramatic increase in the level of latent TGF-beta1 protein in cell lysates with increasing concentrations of DHT. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
3 In addition, results of enzyme-linked immunoadsorbent assay for TGF-beta1 indicated that treatment of LNCaP cells with DHT led to a dose-dependent increase in both total and biologically active TGF-beta1 in the conditioned media. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
4 In addition, results of enzyme-linked immunoadsorbent assay for TGF-beta1 indicated that treatment of LNCaP cells with DHT led to a dose-dependent increase in both total and biologically active TGF-beta1 in the conditioned media. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
5 First, TGF-beta1 neutralizing antibody was added to the culture medium with varying concentrations of DHT. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
6 These observations, taken together, indicate that TGF-beta1 mediates at least in part the growth arrest observed at the high concentration of DHT in LNCaP cells. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
