mainz7g: Subset of MAINZ dataset containing gene expression, annotations and clinical data.

Description

This dataset contains a subset of the gene expression, annotations and clinical data from the MAINZ datasets (see section details). The subset contains the seven genes introduced by Desmedt et al. 2008

Format

ExpressionSet with 7 features and 200 samples, containing:

• exprs(mainz7g): Matrix containing gene expressions as measured by Affymetrix hgu133a technology (single-channel, oligonucleotides).
• fData(mainz7g): AnnotatedDataFrame containing annotations of Affy microarray platform hgu133a.
• pData(mainz7g): AnnotatedDataFrame containing Clinical information of the breast cancer patients whose tumors were hybridized.
• experimentalData(mainz7g): MIAME object containing information about the dataset.
• annotation(mainz7g): Name of the affy chip.

Details

This dataset represents a subset of the study published by Schmidt et al. 2008. The subset contains the genes AURKA (also known as STK6, STK7, or STK15), PLAU (also known as UPA), STAT1, VEGF, CASP3, ESR1, and ERBB2, as introduced by Desmedt et al. 2008. The seven genes represent the proliferation, tumor invasion/metastasis, immune response, angiogenesis, apoptosis phenotypes, and the ER and HER2 signaling, respectively.
