Focal adhesion kinase-YAP signaling axis drives drug-tolerant persister cells and residual disease in NSCLC

ABSTRACT: Targeted therapy is effective in many tumor types including lung cancer, the leading cause of cancer mortality. Paradigm defining examples are targeted therapies directed against non-small cell lung cancer (NSCLC) subtypes with oncogenic alterations in EGFR, ALK and KRAS. The success of targeted therapy is limited by drug-tolerant persister cells (DTPs) which withstand and adapt to treatment and comprise the residual disease state that is typical during treatment with clinical targeted therapies. Here, we integrate studies in patient-derived and immunocompetent lung cancer models and clinical specimens obtained from patients on targeted therapy to uncover a focal adhesion kinase (FAK)-YAP signaling axis that promotes residual disease during oncogenic EGFR-, ALK-, and KRAS-targeted therapies. FAK-YAP signaling inhibition combined with the primary targeted therapy suppressed residual drug-tolerant cells and enhanced tumor responses. This study unveils a FAK-YAP signaling module that promotes residual disease in lung cancer and mechanism-based therapeutic strategies to improve tumor response.

Disruption of the ALK tumor cell proteome by concurrent inhibation of ALK and SRC kinases

Project description:Precision oncology has revolutionized the treatment of ALK-positive lung cancer with targeted therapies. However, refractory tumors with compound mutations or diverse resistance mechanisms remain an unmet clinical need. In this study, we established mouse tumor-derived cell models representing the most common EML4-ALK variants in human lung adenocarcinomas and characterized their proteomic profiles. We demonstrated that Eml4-Alk variant 3 confers a worse response to ALK inhibitors, suggesting its role in promoting resistance. In addition, proteomic analysis of brigatinib-treated cells revealed the upregulation of SRC kinase, which is frequently activated in cancer. Co-targeting of ALK and SRC showed remarkable inhibitory effects on both ALK-driven murine tumor growth and ALK-patient-derived cells. This death mechanism is attributed to the profound perturbation of the (phospho)proteomic landscape, together with a synergistic suppressive effect on the mTOR pathway. Taken together, our study identifies the inhibition of ALK and SRC cells and may offer a promising strategy to overcome resistance mechanisms and improve clinical outcomes in ALK-positive lung cancer patients.

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.

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.

Treatment-induced tumor dormancy through YAP-mediated transcriptional reprogramming of the apoptotic pathway [ChIP + ATAC]

Project description:Eradicating tumor dormancy that develops following oncogene-targeted therapy, including after epidermal growth factor receptor (EGFR) tyrosine kinase inhibitor (TKI) treatment of EGFR-mutant non-small cell lung cancer (NSCLC), is an attractive therapeutic strategy but the mechanisms governing the establishment of tumor dormancy are poorly understood. We observe that blockade of ERK1/2 reactivation following EGFR TKI treatment by combined EGFR/MEK inhibition uncovers cells that survive by entering a senescence-like dormant state, characterized by extensive epigenetic remodeling and high YAP/TEAD activity. YAP/TEAD trigger an epithelial-to-mesenchymal transition (EMT) program and engage the EMT transcription factor SLUG to directly repress pro-apoptotic BMF, limiting drug-induced apoptosis. Pharmacological co-inhibition of YAP or TEAD, or genetic deletion of YAP1, all deplete dormant cells by enhancing EGFR/MEK induced apoptosis. Thus, YAP activation can promote the survival of EGFR-mutant NSCLC cells in the chronic absence of EGFR signaling. Eradicating this population enhances the efficacy of targeted therapies which could ultimately lead to prolonged treatment responses in cancer patients.
