This work describes the molecular cloning of the cDNA encoding the rainbow trout (Oncorhynchus mykiss Walbaum) brain cytochrome P450arom by means of reverse transcriptase and polymerase chain reaction (RT-PCR) and 5'- and 3'-rapid amplification of cDNA ends (RACE) analyses. The results obtained demonstrate that, as in other teleost fishes, the trout genome(More)
To investigate the potential of intracrine or paracrine estrogen synthesis and action in the human thyroid gland and thyroid tumors, the presence of the messenger ribonucleic acids (mRNAs) of both cytochrome P450 aromatase (P450arom) and estrogen receptor (ER) was investigated by RT-PCR with primers designed on the respective coding regions and Southern(More)
In the adult rat, the duodenal tissue of both sexes can convert progesterone to 17alpha-hydroxyprogesterone, androstenedione and testosterone. The transition from C21 to C19 steroids is apparently controlled by the same cytochrome P450c17 expressed in the testis, which catalyzes both 17alpha-hydroxylation and C-17,20 bond scission at a single bifunctional(More)
