...the combination of ALK and STAT3 inhibitors restored the sensitivity of EML4-ALK G1202R mutant cells to ceritinib. In conclusion, these data indicate that the EML4-ALK G1202R mutation mediates the EMT phenotype by activating the STAT3/Slug signaling pathway, resulting in resistance to ceritinib, and that the combination of STAT3 and ALK inhibitors may overcome ALK mutation-driven drug resistance in the clinic.
