LITERATURE

17beta estradiol
-
exposure to 17beta estradiol causes 9% increase of estrone 3-sulfate sulfatase activity in mammary myoepithelial cells after 6 days, but 70% reduction in MCF-7 cells
1alpha,25-dihydroxyvitamin D3
-
upregulation of enzyme activity. In HL-60 cell, stimulation is augmented by retinoid X-receptor agonists, blocked by retinoid X-receptor specific antagonists, and retinoic acid receptor specific agonists and antagonist have no effect. In NB-4 cell, upregulation is unaffected by the specific classical nuclear vitamin D receptor and retinoid X-receptor antagonists, but is blocked by a plasma-membrane associated vitamin D receptor antagonist and increases by plasma-membrane associated vitamin D receptor agonists

plus tumor necrosis factor alpha, increases STS activity in mock transfected MCF-7 cells and further increases STS activity in transfected MCF-7 cells, activation occurs independently of STS promoter and enhancer elements, may activate via a post-translational modification of STS or by increasing substrate availability
