EGFR and lung carcinoma: To investigate the potential antitumoral properties and possible synergistic effect of a PAK inhibitor (IPA-3) combination with several compounds used in cancer treatment, such as EGFR inhibitors (osimertinib and afatinib), PKCι inhibitor (auranofin), MEK inhibitor (trametinib), and a Flk3/Syk, and potential multiple PKC inhibitor (midostaurin), several lung cancer cell lines possessing different molecular characteristics were tested, such as HCC827 (EGFR mutated), H23 (KRAS mutated) and H520 (PAK1 overexpression).
