In conclusion, we have identified several pathways (PI3K/AKT, MAPK, regulation of actin cytoskeleton, focal adhesion) and DEGs (MMP2, MMP9, FGF13, FGF12, NFKB1, PPP2R5B, PPP2R2B, CCNE2, MAPK12, FOS, MAP2K3, MAP2K6, BIRC3, BIRC2, and MLCK) associated with cisplatin resistance in lung cancer cells. This evidence concerns the gene PPP2R5B and lung cancer.
