WebAromatase is a cytochrome P450 enzyme that catalyzes a critical step in the conversion of androgens (C19 steroids) to estrogens (C18 steroids). Mutations in the aromatase gene (CYP19A1) can result in a lack of aromatase activity and, as a consequence, impairment in estrogen biosynthesis. The functional consequences of this deficiency begin in ...

WebSep 25, 2024 · CYP19A1 is a critical enzyme in the E2 synthesis, however, there are limited reports about the molecular mechanism of CYP19A1 regulating BFGCs proliferation, apoptosis, and hormone synthesis. To explore these issues, we designed and synthesized the interference fragment, siCYP19A1, to silence CYP19A1 mRNA expression in BFGCs. WebMar 10, 2024 · Context: The steroidogenic enzyme aromatase (CYP19A1) is required for estrogen biosynthesis from androgen precursors in the ovary and extragonadal tissues. The role of aromatase, and thus estrogens, is best illustrated by genetic variations of the CYP19A1 gene leading to aromatase deficiency or excess..
