GSE13787 Expression Data

In this study, we focused on the oncogenic phosphatidylinositol 3-kinase (PI3K) pathway in twelve BLCs, and compared it to a control series of eleven hormonal receptor negative- and grade III- matched HER2+ carcinomas. The two tumor populations were first characterized by immunohistochemistry and gene expression. The PI3K pathway was then investigated by gene copy-number analysis, gene expression profiling and at a proteomic level using reverse phase protein array technology and tissue microarray. The effects of PI3K inhibition pathway on proliferation and apoptosis was further analyzed in three human basal-like cell lines. Accessed by AnnotatedBCGEData
