Significant Gene Ontology and Pathway Annotations identified for 576 probes corresponding to 395 unique genes differentially expressed between Proneural Oligodendrogliomas/Astrocytomas and Proneural GBM.

Proneural GBM samples have increased expression of genes associated with enhanced vascularization, proliferation, invasion, and inflammation. Count = number of genes identified with each annotation by the three analyses. FDR = false discovery rate. P-value for IPA is based on the hypergeometric distribution.
