In this assay, neither endoxifen nor 4-OH-Tam alone produced any change in the PR mRNA expression. hydroxytamoxifen 149-157 progesterone receptor Homo sapiens 45-47 15685451-13 2005 However, both endoxifen and 4-OH-Tam decreased the E2-induced PR expression with similar potency. hydroxytamoxifen 28-36 progesterone receptor Homo sapiens 62-64 1883484-4 1991 PR was significantly increased following treatment with 4-OH tamoxifen, this response being antagonized in the presence of ICI 164,384. hydroxytamoxifen 56-70 progesterone receptor Homo sapiens 0-2 1965340-4 1990 We have found that: 1) cellular proliferation and estrogen or progesterone receptor concentration were mutually dependent, the greatest estradiol binding capacity was obtained in cells in which mitotic activity had been slowed down (G0/G1) by the antiestrogenic action of hydroxytamoxifen added to the culture; 2) the presence of estradiol in the culture medium induced marked changes in the synthesis and catabolism of estrogen and progesterone receptors; and 3) both receptors acted as functional proteins whose intracellular concentrations varied depending on the phases of the mitotic cycle. hydroxytamoxifen 272-288 progesterone receptor Homo sapiens 62-83 2783569-3 1989 This response to EGF was dose dependent; a half-maximal effect was obtained at 10(-10) M. The antiestrogens tamoxifen and 4-hydroxytamoxifen were able to antagonize the stimulatory effect of EGF on progesterone receptor concentrations, but they did not affect its mitogenic effect. hydroxytamoxifen 122-140 progesterone receptor Homo sapiens 198-219 2783569-4 1989 The inhibitory effect of 4-hydroxytamoxifen depended on concentration; half-maximal inhibition was observed between 0.5-1 X 10(-9) M. 4-Hydroxytamoxifen could completely inhibit the progesterone receptor increase due to EGF even when added to cells already exposed to the growth factor for 6 days. hydroxytamoxifen 25-43 progesterone receptor Homo sapiens 182-203 2783569-4 1989 The inhibitory effect of 4-hydroxytamoxifen depended on concentration; half-maximal inhibition was observed between 0.5-1 X 10(-9) M. 4-Hydroxytamoxifen could completely inhibit the progesterone receptor increase due to EGF even when added to cells already exposed to the growth factor for 6 days. hydroxytamoxifen 134-152 progesterone receptor Homo sapiens 182-203 3620717-3 1987 The antiestrogen 4-hydroxytamoxifen blocked progesterone receptor induction both by estradiol and by phenolphthalein. hydroxytamoxifen 17-35 progesterone receptor Homo sapiens 44-65 7961858-2 1994 We have previously identified an intragenic (+698/+723) estrogen-responsive element present in the progesterone receptor gene, which binds the estradiol receptor and mediates estrogen and 4-OH tamoxifen induction. hydroxytamoxifen 188-202 progesterone receptor Homo sapiens 99-120 7961858-3 1994 Progesterone receptor gene expression was equally stimulated by estradiol and 4-OH tamoxifen in the presence of a NH2 terminally deleted estrogen receptor mutant lacking activation function 1, suggesting that activation function 2 was the predominant activation domain. hydroxytamoxifen 78-92 progesterone receptor Homo sapiens 0-21 29416786-8 2018 These genes, except PGR and CCND1 which were down-regulated, were also up-regulated in ER+ MCF-7 cells by 4-OH-TAM. hydroxytamoxifen 106-114 progesterone receptor Homo sapiens 20-23
