abstract：:Aromatase cytochrome P450, the key enzyme of estrogen biosynthesis from androgens, is encoded by CYP19. Its structure shows some peculiarities: exons II to X encode the protein, while multiple alternative exons I encode unique 5'-untranslated regions of the aromatase mRNA transcripts. Immunohistochemistry studies in t...
