From mouse to humans: detecting preventing vaccination targets associated to breast cancer stem cells. Exon-level analysis

ABSTRACT: TuBo cell line (E) was compared to passage 1 (P1), 2 (P2) and 3 (P3) mammospheres to detect specific transcription isoforms associated to cancer stem cell. TuBo cell line (E) was compared to passage 1 (P1), 2 (P2) and 3 (P3) mammospheres. Exon-level transcription profiling was done using Affimetrix GeneChip Exon 1.0 ST. Exon-level analysis is more complex than gene-level analysis. The number of probesets to be investigated is at least 10 times larger in number than gene-level probesets. Thus results, upon statistical analysis, are massively contaminated by type I statistical errors, i.e. false positive [Della Beffa et al. 2008]. Furthermore, exon-level probesets are based only on four probes, which makes exon-level signal summarization more noisy than gene-level, where signal summarization
