Gene ontology (GO) classification of differentially expressed genes in the carcinoma and papillary adenocarcinoma tumors into Cellular component, Molecular function and Biological process categories. Genes that were differently expressed in the two types of tumors (over twofold and at P ≤ 0.05) were classified to elucidate the cellular subcompartments, functions and processes that account for the differences between phenotypes. Numbers above bars represent the number of genes involved.
