Tissue-specific and hormonally controlled alternative promoters regulate aromatase cytochrome P450 gene expression in human adipose tissue

M S Mahendroo, C R Mendelson, E R Simpson
1993 Journal of Biological Chemistry  
Estrogen biosynthesis is catalyzed by a microsomal enzyme, aromatase cytochrome P450 (P450arom; the product of the CYP19 gene). The human CYP19 gene comprises nine coding exons, II-X.  ...  We conclude that CYP19 gene expression in human adipose tissue likely utilizes two novel promoters and, furthermore, that alternative promoter usage in cultured ASC is a function of the hormonal environment  ...  Acknowledgments-We gratefully acknowledge the skilled editorial assistance of Melissa Meister.
