Vulnerability of drug-resistant EML4-ALK rearranged lung cancer to transcriptional inhibition


ABSTRACT: A subset of lung adenocarcinomas is driven by the EML4-ALK translocation. Despite excellent initial responses in patients, acquired resistance to ALK inhibitors occurs. Exploring these mechanisms of resistance, we found that EML4-ALK cells resistant to ALK inhibitors are remarkably sensitive to THZ1, alvocidib or dinaciclib. These compounds robustly induce apoptosis through transcriptional inhibition and downregulation of anti-apoptotic genes. In conclusion, this study shows that THZ1, alvocidib or dinaciclib could be a therapeutic option for a subset of patients with acquired resistance to first, second and third-generation ALK inhibitors.
