title: Hormonal regulation of catechol-O-methyl transferase activity in women with uterine leiomyomas.
abstract: Catechol-O-methyl transferase (COMT) expression is higher in leiomyomas compared with paired normal myometrium. The expression of COMT in leiomyoma cells is hormonally regulated-estrogen down-regulates, whereas P and dexamethasone up-regulate, COMT expression.
