1 To address potential TGFbeta1 induction by DHT, quantitative PCR and enzyme-linked immunoadsorbent assay were performed in NCI-H295 cells treated with DHT (from 10(-12)-10(-9) mol/L). Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
2 DHT led to a significant dose-dependent increase in TGFbeta1 messenger ribonucleic acid expression and in biologically active TGFbeta1 protein levels in the conditioned media of NCI-H295 cells, demonstrating that androgen can induce TGFbeta1 expression and production. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
3 DHT led to a significant dose-dependent increase in TGFbeta1 messenger ribonucleic acid expression and in biologically active TGFbeta1 protein levels in the conditioned media of NCI-H295 cells, demonstrating that androgen can induce TGFbeta1 expression and production. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
4 DHT led to a significant dose-dependent increase in TGFbeta1 messenger ribonucleic acid expression and in biologically active TGFbeta1 protein levels in the conditioned media of NCI-H295 cells, demonstrating that androgen can induce TGFbeta1 expression and production. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
5 The addition of TGFbeta1-neutralizing antibody to cell cultures treated with different DHT concentrations (10(-9) and 10(-10) mol/L) blocked the inhibitory effect of TGF/beta1 on adrenocortical cell proliferation. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
6 The addition of TGFbeta1-neutralizing antibody to cell cultures treated with different DHT concentrations (10(-9) and 10(-10) mol/L) blocked the inhibitory effect of TGF/beta1 on adrenocortical cell proliferation. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
7 Therefore, it might be reasonable to suppose that DHT could also influence human adrenocortical cell growth by involving TGFbeta1. Dihydrotestosterone transforming growth factor beta 1 Homo sapiens
