Intersection of microarray data identifies common markers of astrocytic cancer cells. Venn diagram depicting the overlap, identified by the supervised hierarchical analysis, between the two pair wise comparisons, GvC and DvC, that was used to identify the 1038 transcripts exhibiting consistent sign changes in expression patterns in trisomic BG01V APCs (samples G) and the CCF-STTG1 astrocytoma cell line (samples D) relative to diploid H9 APCs (samples C), which constitutes the GDvC gene list shown in Additional file 2, Table S2.
