International Journal of Mass Spectrometry: Comprehensive and sensitive proteogenomics data analysis strategy based on complementary multi-stage database search

April 1, 2018

Inamul Hasan Madar, Wonyeop Lee, Xiaojing Wang, Seung-Ik Ko, Hokeun Kim, Dong-Gi Mun, Bing Zhang, Eunok Paek, Sang-Won Lee Proteogenomics provides opportunities for proteomic validation of gene structures, genomic alterations, and functional relevance of novel findings obtained from genomic data analysis. However, for effective proteogenomic data integration, an extensive proteome profiling, approaching the gene coverage […]

Journal of Pediatric Hematology/Oncology: Aerobic Exercise During Early Murine Doxorubicin Exposure Mitigates Cardiac Toxicity

April 1, 2018

Wang, Fei PhD*; Iskra, Brian BS†; Kleinerman, Eugenie MD*; Alvarez-Florez, Claudia PhD*; Andrews, Thomas MSc†; Shaw, Angela MD*; Chandra, Joya PhD*; Schadler, Keri PhD*; Aune, Gregory J. MD, PhD†,‡ Abstract We report the cardioprotective effects of moderate aerobic exercise from parallel pediatric murine models of doxorubicin (Doxo) exposure in non–tumor-bearing immune-competent (NTB-IC) mice and tumor-bearing nude mice (TB-NM).

Technology Networks: Link Discovered Between BRCA1 Protein and Aggressive Pediatric Cancer

March 8, 2018

Scientists with the Greehey Children’s Cancer Research Institute at UT Health San Antonio have discovered a surprising connection between a breast cancer protein, BRCA1, and pediatric cancer called Ewing sarcoma. Their findings, reported March 7 in the journal Nature, reveal a completely new mechanism by which BRCA1 can be rendered dysfunctional. “The observations raise many new […]

UT Health SA Newsroom: Greehey Institute team finds link between BRCA1 and Ewing sarcoma

March 7, 2018

A mutant oncogene in Ewing traps BRCA1 and prevents it from repairing genetic damage. Scientists with the Greehey Children’s Cancer Research Institute at UT Health San Antonio have discovered a surprising connection between a breast cancer protein, BRCA1, and a pediatric cancer called Ewing sarcoma. Their findings, reported March 7 in the journal Nature, reveal a completely new mechanism […]

Nature: EWS–FLI1 increases transcription to cause R-loops and block BRCA1 repair in Ewing sarcoma

March 7, 2018

Aparna Gorthi, July Carolina Romero, Eva Loranc, Lin Cao, Liesl A. Lawrence, Elicia Goodale, Amanda Balboni Iniguez, Xavier Bernard, V. Pragathi Masamsetti, Sydney Roston, Elizabeth R. Lawlor, Jeffrey A. Toretsky, Kimberly Stegmaier, Stephen L. Lessnick, Yidong Chen & Alexander J. R. Bishop Abstract Ewing sarcoma is an aggressive pediatric cancer of the bone and soft tissue. It results from a chromosomal translocation, predominantly t(11;22)(q24:q12), that fuses the N-terminal transactivation domain of […]

Molecular & Cellular Proteomics: Detection of proteome diversity resulted from alternative splicing is limited by trypsin cleavage specificity

March 1, 2018

Xiaojing Wang, Simona G Codreanu, Bo Wen, Kai Li, Matthew C Chambers, Daniel C Liebler, Bing Zhang Alternative splicing dramatically increases transcriptome complexity but its contribution to proteome diversity remains controversial. Exon-exon junction spanning peptides provide direct evidence for the translation of specific splice isoforms and are critical for delineating protein isoform complexity. Here we […]

Cell Stem Cell: Vangl2/RhoA Signaling Pathway Regulates Stem Cell Self-Renewal Programs and Growth in Rhabdomyosarcoma

March 1, 2018

Madeline N Hayes 1, Karin McCarthy 1, Alexander Jin 1, Mariana L Oliveira 2, Sowmya Iyer 1, Sara P Garcia 1, Sivasish Sindiri 3, Berkley Gryder 3, Zainab Motala 4, G Petur Nielsen 5, Jean-Paul Borg 6, Matt van de Rijn 7, David Malkin 4, Javed Khan 3, Myron S Ignatius 8, David M Langenau 9 Abstract Tumor growth and relapse are driven by tumor propagating cells (TPCs). However, mechanisms regulating TPC fate choices, maintenance, and self-renewal are not fully understood. Here, we show that Van […]
