Single-cell transcriptomic analysis uncovers intratumoral heterogeneity and drug-tolerant persister in ALK-rearranged lung adenocarcinoma

Project description:Acquired drug resistance is the major therapeutic obstacle to maintenance treatment of advanced-stage non-small cell lung cancer. Lung adenocarcinoma (ADC) harboring driver mutations also showed poor response to immune checkpoint inhibitors (ICIs). Underlying mechanisms of how drug insensitivity evolves remain unclear. Here we explored the intratumoral heterogeneity of tyrosine kinase inhibitor (TKI)-resistant anaplastic lymphoma kinase (ALK)-rearranged lung ADC organoids using single-cell RNA-sequencing (scRNA-seq) transcriptomic analysis. IL-17 signaling pathway was found highly induced in a subpopulation of pre-existing ALK-TKI-resistant cells. These drug-tolerant persister (DTP) cells, also found to have high surface intracellular adhesion molecule 1 (ICAM-1) expression level, were more resistant towards ALK-TKI and expressed a higher level of cancer-stem cell transcriptional factors. Moreover, tumor cells with high ICAM-1 expression were found spatially correlated with RORɣt+ Th17 infiltration in ALK-rearranged NSCLC resected tumor tissues. In conclusion, our data revealed marked intratumoral heterogeneity in ALK-rearranged tumor, and pre-existing DTP cells may contribute to the development of drug insensitivity in ALK-rearranged lung ADC.

Fibroblast growth factor receptor 3 overexpression mediates ALK inhibitor resistance in ALK-rearranged non-small cell lung cancer

Project description:The rearrangement of anaplastic lymphoma kinase (ALK) occurs in 3%-5% of patients with non-small cell lung cancer (NSCLC) and confers sensitivity to ALK-tyrosine kinase inhibitors (TKIs). For the treatment of patients with ALK-rearranged NSCLC, various additional ALK-TKIs have been developed. Ceritinib is a second-generation ALK-TKI and has shown great efficacy in the treatment of patients with both newly diagnosed and crizotinib, a first-generation ALK-TKI, refractory ALK-rearranged NSCLC. However, tumors can also develop ceritinib resistance. This may result from secondary ALK mutations, but other mechanisms responsible for this have not been fully elucidated. In this study, we explored the mechanisms of ceritinib resistance by establishing ceritinib-resistant, echinoderm microtubule-associated protein-like 4 (EML4)-ALK-positive H3122 cells and ceritinib-resistant patient-derived cells. We identified a mechanism of ceritinib resistance induced by bypass signals that is mediated by the overexpression and activation of fibroblast growth factor receptor 3 (FGFR3). FGFR3 knockdown by small hairpin RNA or treatment with FGFR inhibitors was found to resensitize the resistant cells to ceritinib in vitro and in vivo. FGFR ligands from either human serum or fetal bovine serum were able to activate FGFR3 and induce ceritinib resistance. A detailed analysis of ceritinib-resistant patient-derived specimens confirmed that tyrosine-protein kinase Met (cMET) amplification induces ceritinib resistance. Amplified cMET counter-activated EGFR and/or Her3, and induced ceritinib resistance. These results reveal multiple ceritinib resistance mechanisms and suggest that ceritinib resistance might be able to overcome by identifying precise resistance mechanisms.

Microarray analysis of drug-tolerant cells in ALK-rearranged non-small cell lung cancer cell lines induced by ALK-TKIs

Project description:To investigate the molecular mechanisms underlying the emergence and maintenance of drug-tolerant (DT) cells in anaplastic lymphoma kinase (ALK)-rearranged lung cancer, we isolated DT cells from H2228 and A925L cells exposed to high doses of alectinib or lorlatinib for 9 days, and performed transcriptome analysis between parental and DT cells using a gene expression microarray.
