The scarcity of adequate cell models has limited our understanding of this tumor. Here we describe and characterize a new human liver tumor cell line, Hep293TT, derived from an aggressive childhood hepatoblastoma. […]

Breast Cancer Research Treatment: Pooled analysis indicates that the GSTT1 deletion, GSTM1 deletion, and GSTP1 Ile105Val polymorphisms do not modify breast cancer risk in BRCA1 and BRCA2 mutation carriers

PLOS Genetics: A Network of Conserved Damage Survival Pathways Revealed by a Genomic RNAi Screen

October 19, 2009

Dashnamoorthy Ravi, Amy M. Wiles, Selvaraj Bhavani, Jianhua Ruan, Philip Leder, Alexander J. R. Bishop  Abstract Damage initiates a pleiotropic cellular response aimed at cellular survival when appropriate. To identify genes required for damage survival, we used a cell-based RNAi screen against the Drosophila genome and the alkylating agent methyl methanesulphonate (MMS). Similar studies performed in other model organisms report […]

New England Journal of Medicine: MicroRNA Expression, Survival, and Response to Interferon in Liver Cancer

Junfang Ji, PhD, Jiong Shi, MD, Anuradha Budhu, PhD, Zhipeng Yu, B.S., Marshonna Forgues, B.S., Stephanie Roessler, PhD, Stefan Ambs, PhD, M.P.H., Yidong Chen, PhD, Paul S. Meltzer, MD, Carlo M. Croce, MD, Lun-Xiu Qin, MD, PhD, Kwan Man, MD, PhD, Abstract BACKGROUND Hepatocellular carcinoma is a common and aggressive cancer that occurs mainly in men. We examined microRNA expression patterns, survival, and response to interferon […]

Pediatric Blood & Cancer: Small cell undifferentiated variant of hepatoblastoma: adverse clinical and molecular features similar to rhabdoid tumors

March 1, 2009

Angela D Trobaugh-Lotrario 1, Gail E Tomlinson, Milton J Finegold, Lia Gore, James H Feusner Abstract Background: Small cell undifferentiated (SCU) histology in patients with stage I hepatoblastoma (HB) predicts an increased risk of relapse. We sought to determine the significance of SCU histology in patients with unresectable HB. Procedure: Patients enrolled in the pediatric Intergroup (INT0098) trial for HB and patients […]

Cancer Research: Large-Scale Profiling of Archival Lymph Nodes Reveals Pervasive Remodeling of the Follicular Lymphoma Methylome

February 1, 2009

J. Keith Killian, Sven Bilke, Sean Davis, Robert L. Walker, M. Scott Killian, Erich B. Jaeger, Yidong Chen, Jason Hipp, Stefania Pittaluga, Mark Raffeld, Robert Cornelison, William I. Smith, Jr., Marina Bibikova, Jian-Bing Fan, Michael R. Emmert-Buck, Elaine S. Jaffe and Paul S. Meltzer Abstract Emerging technologies allow broad profiling of the cancer genome for differential DNA methylation relative to benign cells.

Bioinformatics: GEOmetadb: powerful alternative search engine for the Gene Expression Omnibus

December 1, 2008

Yuelin Zhu, Sean Davis, Robert Stephens, Paul S. Meltzer, Yidong Chen Abstract The NCBI Gene Expression Omnibus (GEO) represents the largest public repository of microarray data.
