Cyp19 aromatase
WebHigh levels of aromatase (CYP19) are present in the monkey brain and regulated by androgens in regions thought to be involved in the central regulation of reproduction. … WebCompetitive inhibition of aromatase activity by test chemicals can be detected by serial reaction tubes containing increasing concentrations of the chemical of interest. This protocol has been optimized for use with recombinant microsomes containing human aromatase (CYP19) and cytochrome P450 reductase. This protocol uses relatively large volumes.

WebCYP19gene encodes cytochrome P450 aromatase, the key enzyme which catalyses the final step of conversion of androgens (C19 steroids, testosterone and androstenedione) to estrogens (C18 steroids, estradiol and estrone) in gonadal and extragonadal tissues (11-14). WebIn testis, P450-aromatase, encoded by CYP19, is responsible for the conversion of testosterone to oestradiol. The aims of this study were to quantify CYP19 mRNA expression, aromatase activity and protein localization, and to measure the oestradiol to testosterone ratio in testicular tissues of men with spermatogenic impairment.
