Of particular interest may be PAK4 (log2ratio = 4.09; p = 3.31x10-5), which promotes cell survival [32,33], affects cell adhesion [34] and is implicated in the epithelial-mesenchymal transition in cancer [35], and PA2G4 (log2ratio = 2.58; p = 0.046), a DNA binding protein [36] which is implicated in both development [37] and a variety of cancers [38,39]. The gene discussed is PA2G4; the disease is cancer.
