JCI Insight: IL-6 and CXCL8 mediate osteosarcoma-lung interactions critical to metastasis

August 23, 2018

Hinckley,1,11 Peter J. Houghton,3 and Ryan D. Roberts1,2,4 Abstract: Osteosarcoma (OS), a malignant tumor of bone, kills through aggressive metastatic spread almost exclusively to the lung. Mechanisms driving this tropism for lung tissue remain unknown, though likely invoke […]

CRISPR – Journal: CRISPR-Based Editing Reveals Edge-Specific Effects in Biological Networks

August 1, 2018

Yi Li, Chance M. Nowak, Daniel Withers, Alexander Pertsemlidis, Leonidas Bleris Abstract Unraveling the properties of biological networks is central to understanding both normal and disease cellular phenotypes. Networks consist of functional elements (nodes) that form a variety of diverse connections (edges), with each node being a hub for multiple edges. Herein, in contrast to node-centric network perturbation […]

Cancer Letters: miR-195 potentiates the efficacy of microtubule-targeting agents in non-small cell lung cancer

July 28, 2018

Xiaojie Yuab, Yiqiang Zhanga, Xiuye Maa, Alexander Pertsemlidisabc Abstract Microtubule-targeting agents (MTAs) are widely used for the treatment of non-small cell lung cancer (NSCLC). The response rate is only ∼25%, mainly attributable to drug resistance. To identify the determinants of resistance in NSCLC, we performed a high-throughput screen using a library of miRNA mimics. Here we report that […]

Oncotarget: Increased expression of the thyroid hormone nuclear receptor TRα1 characterizes intestinal tumors with high Wnt activity

July 24, 2018

Joel Uchuya-Castillo, Nicolas Aznar, Carla Frau, Pierre Martinez, Clementine Le Nevé, Laetitia Marisa, Luiz OF Penalva, Pierre Laurent-Puig, Alain Puisieux, Jean-Yves Scoazec, Jacques Samarut, Stephane Ansieau, Michelina Plateroti Our previous work demonstrated a key function of the thyroid hormone nuclear receptor TRα1, a T3-modulated transcription factor, in controlling intestinal development and homeostasis via the Wnt […]

Journal of Clinical Oncology: Cardiovascular Disease in Survivors of Childhood Cancer: Insights Into Epidemiology, Pathophysiology, and Prevention

July 20, 2018

Saro H. Armenian, Gregory T. Armstrong, Gregory Aune, Eric J. Chow, Matthew J. Ehrhardt, Bonnie Ky,  ABSTRACT Cardiovascular disease (CVD), which includes cardiomyopathy/heart failure, coronary artery disease, stroke, pericardial disease, arrhythmias, and valvular and vascular dysfunction, is a major concern for long-term survivors of childhood cancer. There is clear evidence of increased risk of CVD largely attributable to treatment exposures […]

Cell Report: Opposing Tumor-Promoting and -Suppressive Functions of Rictor/mTORC2 Signaling in Adult Glioma and Pediatric SHH Medulloblastoma

July 10, 2018

Here, we […]

Oncotarget: LMO1 functions as an oncogene by regulating TTK expression and correlates with neuroendocrine differentiation of lung cancer

July 3, 2018

Liqin Du1, Zhenze Zhao1, Milind Suraokar2, Spencer S. Shelton1, Xiuye Ma3, Tzu-Hung Hsiao4, John D. Minna5, Ignacio Wistuba2,6 and Alexander Pertsemlidis3,7 ABSTRACT LMO1 encodes a protein containing a cysteine-rich LIM domain involved in protein-protein interactions. Recent studies have shown that LMO1 functions as an oncogene in several cancer types, including non-small cell lung cancer (NSCLC). However, […]
