Cyproterone Acetate 108-127 transforming growth factor, beta 1 Mus musculus 157-190 8912156-11 1996 CONCLUSIONS: The inhibition of growth of androgen receptor-positive hepatocellular carcinoma with cyproterone acetate in male nude mice could be due to G1-phase cell cycle arrest, and to some extent apoptosis induced by increased synthesis of transforming growth factor-beta 1 in tumor, caused by the direct action of cyproterone acetate through androgen receptors, as well as decreased testosterone levels in blood due to cyproterone acetate-induced testicular atrophy.
