Acquired resistance to entrectinib or crizotinib drives differential gene expression in ROS1+ NSCLC

ABSTRACT: Utilizing primary, patient tumor-derived ROS1+ NSCLC cell lines, we derived TKI-resistant cell lines by chronic exposure to TKI in the media. One of our parental, ROS1 TKI-sensitive cell lines harbors a TPM3-ROS1 fusion (CUTO28) and the other harbors a CD74-ROS1 fusion (CUTO37). Entrectinib-resistant (-ER) and crizotinib-resistant (-CR) lines are so named when they are stably proliferating at 500nM concentration of the respective TKI. We sought to investigate transcriptome changes with acquired resistance to entrectinib or crizotinib.

Analysis of ALK TKI sensitive and ALK TKI resistant isogenic pairs of H3122 (EML4-ALK E13;A20) cells

Project description:Starting with H3122 cells, which harbor the EML4-ALK E13;A20 fusion and are known to be sensitive to ALK tyrosine kinase inhibitors, we generated isogenic pairs of ALK TKI sensitive and ALK TKI resistant cell lines using established methods (see Chmeliecki, J et al Science Trans Med 2011). We modeled resistance against the currently FDA approved ALK TKI, crizotinib (also called PF-1066). We also modeled resistance against a novel more potent ALK inhibitor, X-376 (ref: Lovly, CM et al Cancer Research 2011). We compared gene expression profiles between the 'parental' (ALK TKI sensitive) H3122 cells and the drug resistant cells (H3122 CR for Crizotinib resistant cells and H3122 XR for X-376 resistant cells).

Rapid transcriptional changes of ROS1 fusion positive cells in response to crizotinib treatments

Project description:Despite the initial benefit of tyrosine kinase inhibitors targeting ROS1 fusion kinase in non-small cell lung cancer, the complete responses are rare and resistance ultimately develops from residual tumor cells. Although several acquired resistance mechanisms after disease progression have been reported, the adaptative resistance mechanism that contributes to residual diseases before the onset of acquired resistance is less clear. Cellular adaption through the signaling rewiring under primary oncogene inhibition is considered a major mechanism contributing to residual disease. To explore the rapid signaling reprogramming under acute ROS1 inhibition, we treated a panel of ROS1 fusion-positive cells, mostly derived in our lab, with crizotinib for 24 hours and profiled transcriptional changes by RNA-seq. Understanding the molecular mechanism that supports residual disease could help us better target and eliminate drug-tolerant cells, thus improving the responses to ROS1 targeted therapies.

Transcription profiling of ALK-rearranged cell lines resistent and sensitive to crizotinib

Project description:In this study we have analysed the transcription profile of ALK rearranged cell lines (COST, DEL, JB6, KARPAS, SR786, SUPM2, TS). The analysis was done on untreated cell lines and on the te same cell lines surviving to progressive increasing addition of crizotinib to the culture medium. Crizotinib concentration was progressively increased to reach a final concentration of 1 μM. The resulting pool of resistant cells (designated crizotinib-resistant (CR)) were maintained in RPMI with 10% FBS containing 0.5-1 μM crizotinib.

Charaterization of genetic alterations and gene expression signatures found in erlotinib-resistant and erlotinib/crizotinib dual-resistant HCC827 subpopulations

Project description:The non-small cell lung cancer (NSCLC) cell line HCC827 harbors an activating EGFR mutation (exon 19 deletion) that confers sensitivity to the FDA-approved EGFR inhibitor erlotinib. By applying the ClonTracer barcoding system, we were able to show the presence of pre-existing sub-populations in HCC827 that contribute to erlotinib resistance. Prior studies implicated that MET amplification confers resistance to erlotinib in this cell line. Therefore we examined the effects of the c-Met inhibitor crizotinib on the barcoded HCC827 population when treated either sequentially or simultaneously with both inhibitors. Despite the significant reduction in barcode complexity, the erlotinib/crizotinib combination treatment failed to eradicate all of the resistant clones implying the presence of an erlotinib/crizotinib dual resistant subpopulation. We performed transcriptome profiling (RNA-seq) to elucidate the potential resistance mechanisms of the dual resistant subpopulation in comparison to vehicle-treated or single agent erlotinib-resistant HCC827 cell populations as controls. mRNA profiling of the subpopulations of human NSCLC cell line HCC827 that contribute to EGFR inhibitor erlotinib and MET inhibitor crizotinib resistance

RNA-seq analysis revealed that crizotinib-induced cardiomyocyte death, and cardiac dysfunctionapoptosis is related to autophagosome-lysosome fusion and mitochondrial injury

Project description:Crizotinib, a widely used dual ALK/MET/ROS1 inhibitor, have been seriously limited due to cardiac adverse effects. Here, we found that crizotinib caused left ventricular dysfunction, structural damage and pathological remodeling in mice and induced cardiomyocyte apoptosis and mitochondrial injury. Here, we demonstrated that crizotinib lead to aberrant accumulation of MET protein by interrupting autophagosome-lysosome fusion and knockdown of MET expression or re-activating autophagy flux rescued the cardiomyocytes death and mitochondrial injury caused by crizotinib. We identified that inhibition of the phosphorylation of AMPKSer485/491 reduced the transcriptional level of genes required for autophagosome-lysosome fusion by inhibiting the nuclear localization of FoxO1. Recovering the phosphorylation of AMPKSer485/491 by AAV-mediated overexpression of the AMPK (T485D) or metformin treatment rescued the cardiotoxicity caused by crizotinib.

Gene expression profiles of an ALK-fusion driven cell line and its derivatives resistant to crizotinib alone or resistant to crizotinib plus afatinib

Project description:Despite the initial benefit of the tyrosine kinase inhibitors targeting ALK gene fusions in non-small cell lung cancer, resistance to ALK inhibitors is almost inevitable. To determine the acquired resistance mechanism to ALK inhibition, we generated crizotinib-resistant ALK lines by chronically treating H3122 cells (driven by EML4-ALK) with an ALK inhibitor, crizotinib for approximately 3 months. RNA-seq and differential expression analyses were performed to determine the transcriptional changes of H3122-CR cells in comparison to parental H3122 cells. Because we demonstrated EGFR could mediate the early adaptive resistance to crizotinib, we further explored the mechanism that contributes to the resistance to the combination of crizotinib and afatinib. H3122-CAR (crizotinib and afatinib-resistant) cells were generated by treating them with a combination of crizotinib and afatinib for approximately 6 months and then profiled by RNA-seq to determine the associated transcriptional reprogramming.

A comprehensive analysis of metabolomics and transcriptomics reveals a novel crizotinib resistance mechanism in non-small cell lung cancer

Project description:Crizotinib is a first-line targeted therapy against EML4-ALK fusion in non-small cell lung cancer (NSCLC), but the increased resistance limits its clinical application. However, the mechanisms underlying such resistance are largely unexplored. The present study identified ALK protein overexpression in crizotinib-resistant H3122CR cells through immunoblotting. Then, liquid chromatography tandem mass spectrometry-based metabolomics was adopted to investigate metabolic responses. Crizotinib resistance was associated with the reduction of the total lipid content and the increase of organic acid, featuring the upregulation of lipid metabolism. Fatty acid β-oxidation pathway reprogrammed crizotinib-sensitive metabolome to crizotinib-resistant metabolome, resulting in crizotinib resistance. These findings reveal a previously unknown mechanism of crizotinib resistance and suggest promising applications of this approach in prognostic prediction and tailored therapeutics of NSCLC patients.

Fasting potentiates the anticancer activity of Crizotinib

Project description:Background: Tyrosine kinase inhibitors (TKIs) are widely used for treating solid and hematologic malignancies. However, their efficacy is frequently short lived, warranting the search for safe potentiation strategies. Short courses of fasting were shown to sensitize cancer cells to chemo- and radiotherapy while increasing the resistance of healthy tissues to the same agents. The purpose of this study was to assess the potential of fasting to increase the efficacy of TKIs. Methods: starvation-mimicking culture conditions were studied for their ability to potentiate the effects of Epidermal Growth Factor Receptor (EGFR), Human Epidermal Growth Factor Receptor 2 (HER2), Anaplastic Lymphoma Kinase (ALK) and multitarget TKIs in terms of cancer cell growth, signaling cascades inhibition, and changes in gene expression profile in TKI-sensitive cancer cells. In vivo, the activity of crizotinib or regorafenib, weekly cycles of fasting, or their combination was compared in tumor xenografts models. Results: In vitro, starvation-mimicking culture conditions increased the ability of TKIs to block cancer cell growth and to inhibit the mitogen-activated protein kinase (MAPK) signaling pathway. At the gene expression profile level, starvation and crizotinib led to similar changes, but their combination strengthened Rb-, MYC-, and E2F-dependent transcription inhibition. In vivo, both TKIs and cycles of fasting slowed tumor growth, but, when combined, they were significantly more effective than either type of treatment alone. Conclusions: Cycles of fasting or of specifically designed fasting-mimicking diets should be evaluated in clinical studies as a means to potentiate the activity of TKIs in clinical use. RNA was collected from H3122 cells in 4 different conditions: serum, starvation, treated with Crizotinib, starvation and treated with Crizotinib. Each condition was run in quadruplicate

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.
