TL;DR: It is shown that the recurrent CNAs differ between tumor subtypes defined by expression pattern and that stratification of patients according to outcome can be improved by measuring both expression and copy number, especially high-level amplification.
Journal ArticleDOI
Bladder cancer stage and outcome by array-based comparative genomic hybridization.
Ekaterini Blaveri,Jeremy L. Brewer,Ritu Roydasgupta,Jane Fridlyand,Sandy DeVries,Theresa M. Koppie,Sunanda Pejavar,Kshama R. Mehta,Peter R. Carroll,Jeff Simko,Frederic M. Waldman +10 more
TL;DR: Ass associations between measures of genomic instability and bladder cancer clinical phenotype are evaluated and Array-based CGH identified quantitative and qualitative differences in DNA copy number alterations at high resolution according to tumor stage and grade.
Journal ArticleDOI
Chromosomal Instability in Microsatellite-Unstable and Stable Colon Cancer
Karolin Trautmann,Jonathan P. Terdiman,Amy J. French,Ritu Roydasgupta,Nancy Sein,Sanjay Kakar,Jane Fridlyand,Antoine M. Snijders,Donna G. Albertson,Stephen N. Thibodeau,Frederic M. Waldman +10 more
TL;DR: MSI and CIN are not mutually exclusive forms of genomic instability in sporadic colon cancer, with MSI tumors also showing varying degrees of CIN.
Journal ArticleDOI
Chromosomal aberrations in angioimmunoblastic T-cell lymphoma and peripheral T-cell lymphoma unspecified: A matrix-based CGH approach
Christoph Thorns,Boris C. Bastian,Daniel Pinkel,Ritu Roydasgupta,Jane Fridlyand,Hartmut Merz,Manuela Krokowski,Heinz-Wolfram Bernd,Alfred C. Feller +8 more
TL;DR: In this paper, the authors used array-based comparative genomic hybridization (CGH) to study genetic imbalances in 39 Angioimmunoblastic T-cell lymphoma (AILT) and 20 PTCL-u.
Journal ArticleDOI
Aging impacts transcriptomes but not genomes of hormone-dependent breast cancers
Christina Yau,Vita Fedele,Ritu Roydasgupta,Jane Fridlyand,Alan Hubbard,Joe W. Gray,Karen Chew,Shanaz Dairkee,Dan H. Moore,Francesco Schittulli,Stefania Tommasi,Angelo Paradiso,Donna G. Albertson,Christopher C. Benz +13 more
TL;DR: In this paper, the authors show that epigenetic transcriptome changes, more than genotypic variation, account for age-associated differences in sporadic breast cancer incidence and prognosis.
