Molecular biology of channel catfish brain cytochrome P450 aromatase (CYP19A2): cloning, preovulatory induction of gene expression, hormonal gene regulation and analysis of promoter region.

Cytochrome P450 aromatase (CYP19) converts androgens to estrogens. Unlike mammals, teleosts have two CYP19 genes, expressed differentially in ovary (CYP19A1) and neuronal tissues (CYP19A2). The primary purpose of this study was to demonstrate the potential involvement of CYP19A2 in the reproductive endocrinology of teleosts. Channel catfish CYP19A2… CONTINUE READING
