Tamoxifen 76-85 X-box binding protein 1 Homo sapiens 27-50 34559986-6 2021 In particular, we demonstrate that ERalpha RNA binding mediates alternative splicing of XBP1 and translation of the eIF4G2 and MCL1 mRNAs, which facilitates survival upon stress conditions and sustains tamoxifen resistance of cancer cells. Tamoxifen 202-211 X-box binding protein 1 Homo sapiens 88-92 26517687-2 2015 In particular, human X-box binding protein-1(XBP1), a transcription factor which participates in UPR stress signaling, is reported to correlate with poor clinical responsiveness to tamoxifen. Tamoxifen 181-190 X-box binding protein 1 Homo sapiens 45-49 26517687-3 2015 In this study, we develop a tamoxifen-resistant MCF-7 cell line by treating the cell line with low concentration of tamoxifen, and we find that XBP1 is indeed up-regulated at both the mRNA and protein levels compared to normal MCF-7 cells. Tamoxifen 28-37 X-box binding protein 1 Homo sapiens 144-148 26517687-3 2015 In this study, we develop a tamoxifen-resistant MCF-7 cell line by treating the cell line with low concentration of tamoxifen, and we find that XBP1 is indeed up-regulated at both the mRNA and protein levels compared to normal MCF-7 cells. Tamoxifen 116-125 X-box binding protein 1 Homo sapiens 144-148 26517687-4 2015 STF-083010, a novel inhibitor which specifically blocks the XBP1 splicing, reestablishes tamoxifen sensitivity to resistant MCF-7 cells. Tamoxifen 89-98 X-box binding protein 1 Homo sapiens 60-64 26517687-0 2015 A novel chemical, STF-083010, reverses tamoxifen-related drug resistance in breast cancer by inhibiting IRE1/XBP1. Tamoxifen 39-48 X-box binding protein 1 Homo sapiens 109-113 26517687-2 2015 In particular, human X-box binding protein-1(XBP1), a transcription factor which participates in UPR stress signaling, is reported to correlate with poor clinical responsiveness to tamoxifen. Tamoxifen 181-190 X-box binding protein 1 Homo sapiens 21-44 18386815-5 2008 XBP-1 isoforms were measured by quantitative RT-PCR in 100 primary breast cancer patients treated with adjuvant tamoxifen (including 30 ER alpha-negative cases). Tamoxifen 112-121 X-box binding protein 1 Homo sapiens 0-5 17660348-4 2007 Overexpression of spliced XBP1 [XBP1(S)] in ER-positive breast cancer cells leads to estrogen-independent growth and reduced sensitivity to growth inhibition induced by the antiestrogens Tamoxifen and Faslodex in a manner independent of functional p53. Tamoxifen 187-196 X-box binding protein 1 Homo sapiens 26-30 17660348-4 2007 Overexpression of spliced XBP1 [XBP1(S)] in ER-positive breast cancer cells leads to estrogen-independent growth and reduced sensitivity to growth inhibition induced by the antiestrogens Tamoxifen and Faslodex in a manner independent of functional p53.
