Popis: Therapeutic resistance limits effective treatment of non-small cell lung cancer (NSCLC) and a better understanding of mechanisms contributing to resistance and strategies to overcome these are urgently needed. AXL, a TAM family receptor tyrosine kinase, has emerged as a key determinant of resistance to chemotherapy, radiation and targeted therapies in NSCLC and other cancers, through its roles in mediating epithelial-mesenchymal transition (EMT) and immune escape. As several small-molecule AXL inhibitors and anti-AXL biologics are currently in clinical testing, AXL has emerged as a target of interest in treatment-resistant NSCLC. Here, we investigated AXL expression in NSCLC by analyzing genomic, transcriptomic and proteomic profiles across 3 treatment-naïve (1095 tumors) and 2 previously treated (245 tumors) clinical cohorts of lung adenocarcinoma and squamous cell carcinoma. While AXL expression did not vary with disease stage, tumor samples from patients with prior systemic treatment (and subsequent relapse) had significantly higher AXL expression and were more likely to have undergone EMT (based on our published EMT score), as compared to treatment-naïve NSCLC patients (p 0.3; p Citation Format: Kavya Ramkumar, Carminia M.
