ABSTRACT
Aim To investigate the phytoestrogenic effects and mechanism on ER?,ER? expression levels at the protein of quercetin and psoralen in T47D cells.Methods T47D cells were treated with 10 ?mol?L-1 quercetin and 10 ?mol?L-1 psoralen for 48h respectively,total cell extracts examined for the levels of ER? and ER? protein by RT-PCR and Western blot analysis.The estrogen-like effect of quercetin and psoralen and their relations with the estrogen-receptor were evaluated by pure estrogen receptor antagonist ICI182,780 as a tool.Results Psoralen(10 ?mol?L-1) and quercetin(10 ?mol?L-1) up-regulated the expression of ER? mRNA and protein,without any effect on ER? mRNA and protein levels.The above up-regulation on ER? protein could be inhibited by adding estrogen receptor antagonism ICI182,780.Conclusion Psoralen and quercetin exerts estrogenic activity to ER-positive cells proliferation through interaction with ER? expression.
