Cyproterone Acetate 173-192 transforming growth factor, beta 1 Rattus norvegicus 25-35 9163675-0 1997 EGF- and CPA-induced mitogenic stimuli are differentially down-regulated by TGF-beta1 in cultured rat hepatocytes. Cyproterone Acetate 9-12 transforming growth factor, beta 1 Rattus norvegicus 76-85 9163675-5 1997 The corresponding down-regulation of CPA-induced PCNA expression required a 3- to 5-fold higher TGF-beta1 concentration than for EGF-induced expression. Cyproterone Acetate 37-40 transforming growth factor, beta 1 Rattus norvegicus 96-105 9163675-6 1997 In contrast, CPA-exposed hepatocytes become vulnerable to and EGF-exposed cells protected against the apoptosis-inducing activity of TGF-beta1 (>0.1 ng/ml). Cyproterone Acetate 13-16 transforming growth factor, beta 1 Rattus norvegicus 133-142 9163675-8 1997 It is concluded that EGF and CPA induce their growth stimuli preferentially in the periportal area of the liver but in different hepatocyte sub-populations, which differ in their down-regulation of premitotic events by TGF-beta1. Cyproterone Acetate 29-32 transforming growth factor, beta 1 Rattus norvegicus 219-228 9163675-9 1997 At low TGF-beta1 concentrations, EGF-stimulated cells shift back into a resting cell cycle phase, whereas CPA-treated hepatocytes are eliminated by apoptosis at higher TGF-beta1 concentrations. Cyproterone Acetate 106-109 transforming growth factor, beta 1 Rattus norvegicus 168-177
