TranscriptomicsGene expression patterns and TP53 mutations are associated with HPV RNA status, lymph node metastasis, and survival in head and neck cancer
A growing proportion of head and neck squamous cell carcinomas (HNSCC) is associated with the human papilloma virus (HPV), particularly HPV16. We compare tumors with different HPV16 DNA and RNA (E6*I) status from 290 consecutively recruited HNSCC patients by gene expression profiling and targeted se...

TranscriptomicsTranslocations Activating IRF4 Identify a Subtype of Germinal-Center-Derived B-cell Lymphoma Affecting Predominantly Children and Young Adults
Background: Germinal center B-cell (GCB) lymphomas are common in children and adults. The prognosis strongly depends on age. Subgroups of GCB-lymphomas are characterized by chromosomal translocations affecting immunoglobulin (IG) loci leading to oncogene deregulation. Methods: Novel IG translocation...

TranscriptomicsMassive Transcriptional Perturbation in Subgroups of Diffuse Large B-cell Lymphomas
Based on the assumption that molecular mechanisms involved in cancerogenesis are characterized by groups of coordinately expressed genes, we developed and validated a novel method for analyzing transcriptional data called Correlated Gene Set Analysis (CGSA). Using 50 extracted gene sets we identifie...

TranscriptomicsTranscription profiling of human Burkitts lymphomas
The distinction between the Burkitt lymphoma and diffuse large B-cell lymphoma is imprecise using current diagnostic criteria. We applied transcriptional and genomic profiling to molecularly define Burkitt lymphoma. Gene expression profiling employing Affymetrix GeneChips (U133A) was performed in 22...

TranscriptomicsBiologic characterization of adult MYC-positive mature B-cell lymphomas other than molecular Burkitt lymphoma
MYC translocations are the biologic hallmark of Burkitt lymphomas but also occur in other mature B-cell lymphomas. If accompanied by chromosomal breaks targeting the BCL2 and/or BCL6 oncogenes, these MYC translocation-positive (MYC+) lymphomas are called double-hit lymphomas (DHLs); otherwise, the t...
