Pathways to tamoxifen resistance

RB Riggins, RS Schrecengost, MS Guerrero… - Cancer letters, 2007 - Elsevier
Therapies that target the synthesis of estrogen or the function of estrogen receptor(s) have
been developed to treat breast cancer. While these approaches have proven to be beneficial …

Human X‐box binding protein‐1 confers both estrogen independence and antiestrogen resistance in breast cancer cell lines

BP Gomez, RB Riggins, AN Shajahan… - The FASEB …, 2007 - Wiley Online Library
Human X‐box binding protein‐1 (XBP1) is an alternatively spliced transcription factor that
participates in the unfolded protein response (UPR), a stress‐signaling pathway that allows …

Functions of the adapter protein Cas: signal convergence and the determination of cellular responses

AH Bouton, RB Riggins, PJ Bruce-Staskal - Oncogene, 2001 - nature.com
Since Cas was first identified as a highly phosphorylated 130 kilodalton protein that associated
with the v-Src and v-Crk-oncoproteins, considerable effort has been made to determine …

Interferon regulatory factor-1 (IRF-1) exhibits tumor suppressor activities in breast cancer associated with caspase activation and induction of apoptosis

KB Bouker, TC Skaar, RB Riggins… - …, 2005 - academic.oup.com
We have directly assessed the ability of interferon regulatory factor-1 (IRF-1) to act as a
tumor suppressor gene in human breast cancer cells and explored whether this suppressor …

Differential dependency network analysis to identify condition-specific topological changes in biological networks

B Zhang, H Li, RB Riggins, M Zhan, J Xuan… - …, 2009 - academic.oup.com
Motivation: Significant efforts have been made to acquire data under different conditions and
to construct static networks that can explain various gene regulation mechanisms. However…

ERRγ mediates tamoxifen resistance in novel models of invasive lobular breast cancer

RB Riggins, JPJ Lan, U Klimach, A Zwart, LR Cavalli… - Cancer research, 2008 - AACR
One-third of all estrogen receptor (ER)–positive breast tumors treated with endocrine
therapy fail to respond, and the remainder is likely to relapse in the future. Almost all data on …

The nuclear factor κB inhibitor parthenolide restores ICI 182,780 (Faslodex; fulvestrant)–induced apoptosis in antiestrogen-resistant breast cancer cells

RB Riggins, A Zwart, R Nehra, R Clarke - Molecular cancer therapeutics, 2005 - AACR
The molecular mechanisms underlying the acquisition of resistance to the antiestrogen Faslodex
are poorly understood, although enhanced expression and activity of nuclear factor κB (…

[HTML][HTML] The mitochondrial citrate carrier, SLC25A1, drives stemness and therapy resistance in non-small cell lung cancer

…, R Mosaoa, MS Ongkeko, KA Kim, RB Riggins… - Cell Death & …, 2018 - nature.com
Therapy resistance represents a clinical challenge for advanced non-small cell lung cancer (NSCLC),
which still remains an incurable disease. There is growing evidence that cancer-…

NF-κB signaling is required for XBP1 (unspliced and spliced)-mediated effects on antiestrogen responsiveness and cell fate decisions in breast cancer

R Hu, A Warri, L Jin, A Zwart, RB Riggins… - … and cellular biology, 2015 - Am Soc Microbiol
Antiestrogen therapy induces the unfolded protein response (UPR) in estrogen receptor-positive
(ER+) breast cancer. X-box binding protein 1 (XBP1), which exists in the …

[HTML][HTML] Identifying cancer biomarkers by network-constrained support vector machines

L Chen, J Xuan, RB Riggins, R Clarke, Y Wang - BMC systems biology, 2011 - Springer
Background One of the major goals in gene and protein expression profiling of cancer is to
identify biomarkers and build classification models for prediction of disease prognosis or …
