Activation of an IL6 Inflammatory Loop Mediates Trastuzumab Resistance in HER2+ Breast Cancer by Expanding the Cancer Stem Cell Population
Hasan Korkaya,Gwang Il Kim,April Davis,Fayaz Malik,N. Lynn Henry,Suthinee Ithimakin,Ahmed A. Quraishi,Nader Tawakkol,Rosemarie C. D'Angelo,Amanda K. Paulson,Susan Chung,Tahra Luther,Hayley J. Paholak,Suling Liu,Khaled A. Hassan,Qin Zen,Shawn G. Clouthier,Max S. Wicha +17 more
TL;DR: It is demonstrated that trastuzumab resistance may be mediated by an IL6 inflammatory loop and suggested that blocking this loop may provide alternative strategy to overcometrastuzuab resistance.
Journal ArticleDOI
HER2 Drives Luminal Breast Cancer Stem Cells in the Absence of HER2 Amplification: Implications for Efficacy of Adjuvant Trastuzumab
Suthinee Ithimakin,Kathleen C. Day,Fayaz Malik,Qin Zen,Scott J. Dawsey,Tom Bersano-Begey,Ahmed A. Quraishi,Kathleen M. Woods Ignatoski,Stephanie Daignault,April Davis,Christopher L. Hall,Nallasivam Palanisamy,Amber Heath,Nader Tawakkol,Tahra Luther,Shawn G. Clouthier,Whitney A. Chadwick,Mark L. Day,Celina G. Kleer,Dafydd G. Thomas,Daniel F. Hayes,Hasan Korkaya,Max S. Wicha +22 more
TL;DR: It is shown that HER2 is selectively expressed in and regulates self-renewal of the cancer stem cell (CSC) population in estrogen receptor-positive, HER2(-) luminal breast cancers, and a CSC model in which maximal clinical benefit is achieved when CSC targeting agents are administered in the adjuvant setting is supported.
Journal ArticleDOI
Notch Reporter Activity in Breast Cancer Cell Lines Identifies a Subset of Cells with Stem Cell Activity
Rosemarie C. D'Angelo,Maria Ouzounova,Maria Ouzounova,April Davis,Daejin Choi,Stevie M. Tchuenkam,Gwangil Kim,Tahra Luther,Ahmed A. Quraishi,Yasin Senbabaoglu,Sarah J. Conley,Shawn G. Clouthier,Khaled A. Hassan,Max S. Wicha,Hasan Korkaya,Hasan Korkaya +15 more
TL;DR: A molecular mechanism for the role of Notch-mediated regulation of breast CSCs is revealed and a compelling rationale for CSC-targeted therapeutics is provided.
Journal ArticleDOI
SOCS3-mediated regulation of inflammatory cytokines in PTEN and p53 inactivated triple negative breast cancer model
Gwangil Kim,Maria Ouzounova,Ahmed A. Quraishi,April Davis,Nader Tawakkol,Shawn G. Clouthier,Fayaz Malik,Amanda K. Paulson,Rosemarie C. D'Angelo,Sumeyye Korkaya,Trenton L. Baker,Elif Serap Esen,Aleix Prat,Suling Liu,Celina G. Kleer,Dafydd G. Thomas,Max S. Wicha,Hasan Korkaya +17 more
TL;DR: These studies uncover important connections between inflammation and carcinogenesis and suggest that blocking pro-inflammatory cytokines may be utilized as an attractive strategy to target triple negative breast tumors, which currently lacks molecularly targeted therapies.
Proceedings ArticleDOI
Abstract 3866: Inactivation of p53/PTEN confers a specific epigenetic profile regulated by IL6-SOCS3 signaling
Maria Ouzounova,Gwangil Kim,April Davis,Ahmed A. Quraishi,Nader Tawakkol,Shalini Kota,Max S. Wicha,Hasan Korkaya +7 more
TL;DR: The results suggest that interplay between genetic and epigenetic changes during malignant transformation of mammary epithelial cells may activate multiple signaling cascades and reconstitution of SOCS3 may have therapeutic utility in TNBC.
