1 Involvement of transcription factor Sp1 in quercetin-mediated inhibitory effect on the androgen receptor in human prostate cancer cells. Quercetin androgen receptor Homo sapiens
2 Our previous study has shown that quercetin, one of the main polyphenols, can effectively inhibit the expression and function of the AR. Quercetin androgen receptor Homo sapiens
3 The present study is to address if quercetin may affect Sp1"s action on AR transactivation activity in human prostate adenocarcinoma cell lines, LNCaP and PC-3. Quercetin androgen receptor Homo sapiens
4 However, the state of interaction of Sp1 with the AR treated by quercetin plus androgen was different from that by androgen treatment or none as demonstrated by coimmunoprecipitation experiments and glutathione S-transferase (GST) pull-down assays. Quercetin androgen receptor Homo sapiens
5 Moreover, we showed that quercetin caused changes in post-translational modification of AR protein. Quercetin androgen receptor Homo sapiens
6 The above findings strongly suggest that changes induced by quercetin in post-translational modification of the AR and in states of physical interaction of Sp1 with the AR may be critical for the attenuation of AR"s function. Quercetin androgen receptor Homo sapiens
7 The above findings strongly suggest that changes induced by quercetin in post-translational modification of the AR and in states of physical interaction of Sp1 with the AR may be critical for the attenuation of AR"s function. Quercetin androgen receptor Homo sapiens
8 The above findings strongly suggest that changes induced by quercetin in post-translational modification of the AR and in states of physical interaction of Sp1 with the AR may be critical for the attenuation of AR"s function. Quercetin androgen receptor Homo sapiens
