  1. The data represent the ontological and functional categories identified as overrepresented in the lists of differentially expressed genes, when compared to all genes in the human genome. The lists are provided by the DAVID analysis program [17,19]. a) Top ten categories with best p-values. b) Selected categories with p-value better than 10-4. For complete list of categories with p-values better than 10-4 see Additional file 3; the selected categories represent our choices as the ones that illustrate the best differences between resistant and sensitive cell lines. c) Genes expressed in ErbB signaling pathway and Ras protein signal transduction ontologies of sensitive and resistant cell lines respectively. d) Genes expressed in immune system development of sensitive versus resistant cell lines.
