Androstenedione 242-257 aldo-keto reductase family 1, member C12 Rattus norvegicus 315-351 12830367-1 2003 Exposure of pubertal rats to di-(2-ethylhexyl) phthalate (DEHP) for 14 days was reported to result in reduced testosterone (T) biosynthesis by altering androstenedione 17beta-hydroxysteroid dehydrogenase (17beta-HSD) activity. Androstenedione 152-167 aldo-keto reductase family 1, member C12 Rattus norvegicus 168-203 9475159-5 1998 The present results demonstrate that only 17beta-hydroxysteroid dehydrogenase seems to be involved in the AA action, since nearly 60% inhibition of testosterone production was found when the cells were incubated with androstenedione. Androstenedione 217-232 aldo-keto reductase family 1, member C12 Rattus norvegicus 42-77 3199812-0 1988 Aromatase-inhibitors of the androstenedione-type activate the 17 beta-hydroxysteroid-dehydrogenase in the rat testis tissue suspension model. Androstenedione 28-43 aldo-keto reductase family 1, member C12 Rattus norvegicus 62-98 2158194-2 1990 5 alpha-reductase and 17 beta-hydroxysteroid dehydrogenase activities, which are involved in the conversion of testosterone to dihydrotestosterone and androstenedione, respectively, were low in cultured neonatal interstitial cells, were unresponsive to hCG and declined to undetectable levels during 14 days of culture. Androstenedione 151-166 aldo-keto reductase family 1, member C12 Rattus norvegicus 22-58 3199812-4 1988 The consequent consideration of the whole labelled steroidal spectrum in each experiment leads to the conclusion that androstenedione and the derived aromatase inhibitors activate the 17 beta-hydroxysteroid-dehydrogenase in a product activating manner. Androstenedione 118-133 aldo-keto reductase family 1, member C12 Rattus norvegicus 184-220 2850159-7 1988 When 14C-labeled androstenedione was incubated with microsomal fraction of testicular or ovarian tissue, glycyrrhizin and glycyrrhetinic acid inhibited the conversion of androstenedione to testosterone, indicating that these compounds inhibit the activity of 17 beta-hydroxysteroid dehydrogenase (EC. Androstenedione 170-185 aldo-keto reductase family 1, member C12 Rattus norvegicus 259-295 2850159-7 1988 When 14C-labeled androstenedione was incubated with microsomal fraction of testicular or ovarian tissue, glycyrrhizin and glycyrrhetinic acid inhibited the conversion of androstenedione to testosterone, indicating that these compounds inhibit the activity of 17 beta-hydroxysteroid dehydrogenase (EC. Androstenedione 17-32 aldo-keto reductase family 1, member C12 Rattus norvegicus 259-295 6243214-2 1980 To investigate this phenomenon, the activity of 17 beta-hydroxysteroid dehydrogenase, the enzyme directly related to testosterone production from androstenedione, was measured. Androstenedione 146-161 aldo-keto reductase family 1, member C12 Rattus norvegicus 48-84 3161163-6 1985 17 beta-hydroxysteroid dehydrogenase favored androstenedione formation, and hence oestrone formation, in the ovaries and testosterone formation, and hence oestradiol formation, in the testes.
