Summary of the potential erlotinib biomarker genes identified using pathway fitness scores.

Column 1 identifies the meta-cluster as viewed in Fig 4. Column 2 list whether the pathway fitness score is positive (+) or negative (-). Column 3 lists the gene. Column 4 lists the differential gene expression comparing responders(R) to non-responders(N). Over expression in responders is indicated by a +/-, and vice versa for over expression in non-responders. Column 5 lists the putative MOAs.
