Tamoxifen 177-186 AKT serine/threonine kinase 1 Homo sapiens 60-63 15151944-3 2004 Understanding the targets of Akt signaling mediating tamoxifen resistance is of clinical significance. Tamoxifen 53-62 AKT serine/threonine kinase 1 Homo sapiens 29-32 15151944-5 2004 In the present study, we found that Akt activity correlated with phosphorylation of I kappa B (the negative regulator of NF-kappa B), NF-kappa B DNA binding and tamoxifen resistance in vivo. Tamoxifen 161-170 AKT serine/threonine kinase 1 Homo sapiens 36-39 15151944-6 2004 Importantly, we found that co-treatment with the NF-kappa B inhibitor, parthenolide, or overexpression of I kappa B superrepressor restored tamoxifen sensitivity to our refractory Akt MCF-7 cells. Tamoxifen 140-149 AKT serine/threonine kinase 1 Homo sapiens 180-183
