Co-regulated expression of HAND2and DEINby a bidirectional promoter with asymmetrical activity in neuroblastoma (2009)

Voth, Harald, Oberthuer, André, Simon, Thorsten, Kahlert, Yvonne, Berthold, Frank, Fischer, Matthias

Abstract Background HAND2 , a key regulator for the development of the sympathetic nervous system, is located on chromosome 4q33 in a head-to-head orientation with DEIN , a recently identified novel...

Treatment of early childhood medulloblastoma by postoperative chemotherapy and deferred radiotherapy (2009)

Rutkowski, Stefan, Gerber, Nicolas Ulrich, Von Hoff, Katja, Gnekow, Astrid, Bode, Udo, Graf, Norbert, ...

To investigate the utility of postoperative chemotherapy in delaying radiotherapy and to identify prognostic factors in early childhood medulloblastoma, we studied children younger than 3 years of...

Featured Article The Tumor-Associated Antigen PRAME Is Universally Expressed in High-Stage Neuroblastoma and Associated with Poor Outcome (2008)

André Oberthuer, Barbara Hero, Rüdiger Spitz, Frank Berthold, Matthias Fischer

Purpose: The tumor-associated antigen PRAME, a potential candidate for immunotherapeutic targeting, is frequently expressed in a variety of cancers. However, no information about its presence in...

Gene-expression based classification of neuroblastoma patients using a customized oligonucleotide-microarray outperforms current clinical risk stratification (2006)

Oberthuer, André, Berthold, Frank, Warnat, Patrick, Hero, Barbara, Kahlert, Yvonne, Spitz, Rüdiger, ...

PURPOSE: To develop a gene expression–based classifier for neuroblastoma patients that reliably predicts courses of the disease. PATIENTS AND METHODS: Two hundred fifty-one neuroblastoma specimens...

cDNA array-CGH profiling identifies genomic alterations specific to stage and MYCN-amplification in neuroblastoma (2004)

Chen, Qing-Rong, Bilke, Sven, Wei, Jun S, Whiteford, Craig C, Cenacchi, Nicola, Krasnoselsky, Alexei L, ...

Abstract Background Recurrent non-random genomic alterations are the hallmarks of cancer and the characterization of these imbalances is critical to our understanding of tumorigenesis and cancer...

Retention of imprinting of the human apoptosis-related gene TSSC3 in human brain tumors (2000)

Müller, Sabine, Van Den Boom, Dirk, Zirkel, Dorothea, Köster, Hubert, Berthold, Frank, Schwab, Manfred, ...

Genomic imprinting is the result of a gamete-specific modification leading to parental origin-specific gene expression in somatic cells of the offspring. Several embryonal tumors show loss of...

Classification and diagnostic prediction of cancers using gene expression profiling and artificial neural networks

Khan, Javed, Wei, Jun S., Ringnér, Markus, Saal, Lao H., Ladanyi, Marc, Westermann, Frank, ...

The purpose of this study was to develop a method of classifying cancers to specific diagnostic categories based on their gene expression signatures using artificial neural networks (ANNs). We...

Prediction of Clinical Outcome Using Gene Expression Profiling and Artificial Neural Networks for Patients with Neuroblastoma

Wei, Jun S., Greer, Braden T., Westermann, Frank, Steinberg, Seth M., Son, Chang-Gue, Chen, Qing-Rong, ...

Currently, patients with neuroblastoma are classified into risk groups (e.g., according to the Children’s Oncology Group risk-stratification) to guide physicians in the choice of the most...

Full-Length Telomerase Reverse Transcriptase Messenger RNA Is an Independent Prognostic Factor in Neuroblastoma

Krams, Matthias, Hero, Barbara, Berthold, Frank, Parwaresch, Reza, Harms, Dieter, Rudolph, Pierre

Telomerase activity (TA) is the most recently recognized prognostic factor in neuroblastoma, and its outstanding predictive power was documented by several studies. However, TA measurements require...

Reliable Transcript Quantification by Real-Time Reverse Transcriptase-Polymerase Chain Reaction in Primary Neuroblastoma Using Normalization to Averaged Expression Levels of the Control Genes HPRT1 and SDHA

Fischer, Matthias, Skowron, Matthias, Berthold, Frank

Real-time reverse transcriptase-polymerase chain reaction (RT-PCR) represents a sensitive and efficient technique to determine expression levels of target genes in multiple samples and is...
