  1. The GO analysis was applied to differentially expressed genes from the comparison TP3 vs. Control. The number of genes belonging to a GO term represented on the microarray (annotated), the number genes in the analyzed gene list (significant) and the expected number of genes by chance are given. The upper part of the table shows GO terms that are highly significant for under-represented genes (p-value < 0.01); the lower part indicates terms that are highly significant for over-represented genes. Calculated p-values for each category from three similar methods (classic, elim, weight) are shown. Each table is separated into three different parts representing the following ontologies: Biological Process (BP), Molecular Function (MF) and Cellular Component (CC).
