Targeting the drug tolerant persister (DTP) state in cancer cells should prevent further development of resistance mechanisms. This study explored combination therapies to inhibit alectinib-induced DTP cell formation from anaplastic lymphoma kinase-positive non-small cell lung cancer (ALK + NSCLC) patient-derived cells. After drug-screening 3114 compounds, pan-HER inhibitors (ErbB pathway) and tankyrase1/2 inhibitors (Wnt/β-catenin signaling) emerged as top candidates to inhibit alectinib-induce ...[more]

ALK fusion NSCLC oncogenes promote survival and inhibit NK cell responses via SERPINB4 expression

Project description:Anaplastic lymphoma kinase (ALK) fusion variants in non-small-cell-lung cancer (NSCLC) consist of numerous dimerising fusion partners, with the most common being EML4. Clinical data suggests that the degree of treatment benefit in response to ALK tyrosine kinase inhibitors (TKIs) differs among the variant present in the patient tumor. Therefore, a better understanding the oncogenic signaling networks driven by different ALK-fusion variants is important. Here, we developed highly controlled doxycycline-inducible cell models bearing four different ALK fusion proteins, namely EML4-ALK-V1, EML4-ALK-V3, KIF5B-ALK, and TFG-ALK, in the context of non-tumorigenic NL20 human bronchial epithelial cells. These were complimented by patient-derived NSCLC cell lines harboring either EML4-ALK-V1 or EML4-ALK-V3 fusions. RNAseq and phosphoproteomics analysis were employed to identify dysregulated genes and hyper/hypo-phosphorylated proteins associated with ALK fusion expression. Among ALK fusion induced responses, we noted a robust inflammatory signature that included up-regulation of the Serpin B4 serine protease inhibitor in both NL20-inducible cell models and ALK-positive NSCLC patient-derived cell lines. We show that STAT3 is a major transcriptional regulator of SERPINB4 downstream of ALK fusions, along with NF-B and AP1. The upregulation of SERPINB4 promotes survival of ALK fusion expressing cells and inhibits natural killer (NK) cell-mediated cytotoxicity. In conclusion, our study reveals a novel ALK downstream survival axis that regulates Serpin B4 expression and identifies a molecular target that has potential for therapeutic impact targeting the immune response together with ALK TKIs in NSCLC.

Overcoming AXL Activation and Epithelial–Mesenchymal Transition is Critical in Conquering ALK-positive Non–Small Cell Lung Cancer

Project description:Anaplastic lymphoma kinase tyrosine kinase inhibitors (ALK-TKIs) induce a dramatic response in non–small cell lung cancer (NSCLC) patients with the ALK fusion gene. However, acquired resistance to ALK-TKIs in lung cancer cells remains an inevitable problem: ALK secondary mutations and bypass pathways have been reported as major resistance mechanisms. In this study, we aimed to discover a novel mechanism of acquired resistance to ALK-TKIs and a strategy to conquer ALK-positive lung cancer. We established three types of ALK-TKI (crizotinib, alectinib and ceritinib)–resistant H2228 non-small cell lung cancer cell lines by high exposure and stepwise methods. We found these cells showed a loss of ALK signaling, overexpressed AXL with epithelial–mesenchymal transition (EMT), and had cancer stem cell–like properties. Similarly, we demonstrated that TGF-β1 treated H2228 cells also showed AXL overexpression with EMT features and ALK-TKI–resistance. The AXL inhibitor, R428, or HSP90 inhibitor, ganetespib, were effective in reversing ALK-TKI–resistance and EMT changes in both ALK-TKI–resistant and TGF-β1–exposed H2228 cells. Progression-free survival of ALK-positive NSCLC patients with AXL overexpression was shorter than that of patients who underwent crizotinib therapy and showed low AXL expression. Thus, we found ALK signaling-independent AXL overexpression and EMT features were commonly involved in intrinsic and acquired resistance to first and second generation ALK-TKIs. This suggests AXL and HSP90 inhibitors may be promising therapeutic drugs to overcome tumor cells in ALK-positive NSCLC patients.

Single-cell multi-omics reveals tumor microenvironment factors underlying poor immunotherapy responses in ALK-positive lung cancer

Project description:Anaplastic lymphoma kinase (ALK) rearrangement is a major oncogenic driver in non-small cell lung cancer (NSCLC). While ALK tyrosine kinase inhibitors have shown promising therapeutic effects, overcoming resistance with immunotherapy becomes necessary when resistance develops. However, various clinical trials have revealed that their efficacies remain limited. To investigate the tumor microenvironment (TME) factors contributing to poor immune checkpoint blockade responses in ALK-positive patients, we performed single-cell RNA and ATAC sequencing on lung adenocarcinoma (LUAD) tumors with and without ALK rearrangements. Integrative analysis with additional public LUAD cohorts revealed distinct immune landscapes in ALK-positive tumors, marked by enriched innate immunity and depleted adaptive immunity. ALK-positive malignant cells exhibit higher stemness and aggressive phenotype. Tumor-associated macrophages (TAMs) in these tumors predominantly maintain pro-tumoral M2-like states, reinforcing immune suppression. B cells show reduced immune reactivity and impaired tertiary lymphoid structure formation, while CD8+ T cells display bystander-like signatures and reduced tumor reactivity. Single-cell chromatin accessibility profiles combined with regulatory network analysis suggest that differences in transcription factor activities, rather than chromatin accessibility, may underlie T cell dysfunction. These findings provide insights into the immunosuppressive TME of ALK-positive LUAD, potentially explaining the failure of recent immunotherapy trials and highlighting targets for improving efficacy.

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.

Gene Changes Following in vitro Alectinib Treatment in EML4-ALK Murine NSCLC Cells

Project description:First line treatment for EML4-ALK fusion-positive lung cancer patient is the use of an ALK tyrosine kinase inhibitor (TKI), such as alectinib. While most patients initially respond to this therapy, many patients often develop relapse, and efficacious therapies for patients with relapse disease are limited. To study EML4-ALK fusion-positive lung cancer, novel murine lung cancer cell lines were generated from C57BL/6 mice using an intratracheally injected Adeno-virus that contains Cas9 and guide RNAs for the EML4-ALK translocation, which leads to the development of lung tumors. Cell lines were derived from these tumors. In an effort to better understand how cells respond to alectinib, we treated EML4-ALK-positive murine cell lines (EA1, EA2, and EA3 cells) in vitro for 1-7 days with either 100nM alectinib or DMSO-control. At each time point, RNA was isolated from each condition. RNA was submitted to RNA-seq. Differential analysis on the RNA-seq data was performed to determine and track gene changes over time between control and treated cells. These data will allow us to better develop novel therapeutics to use in conjunction with alectinib when treating EML4-ALK fusion-positive patients.

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.
