摘要

majority of estrogen receptor positive (ER +) breast cancers are growth stimulated by estrogens. The ability to inhibit the ER signaling pathway is therefore of critical importance in the current treatment of ER + breast cancers. It has been reported that l alpha,25-dihydroxyvitamin D-3 down-regulates the expression of the CYP19A1 gene, encoding the aromatase enzyme that catalyzes the synthesis of estradiol. Furthermore, l alpha,25-dihydroxyvitamin D-3 has also been reported to down-regulate the expression of estrogen receptor alpha (ER alpha), the main mediator of ER signaling.
