UNLABELLED The success in lung cancer therapy with programmed death (PD)-1 blockade suggests that immune escape mechanisms contribute to lung tumor pathogenesis. We identified a correlation between EGF receptor (EGFR) pathway activation and a signature of immunosuppression manifested by upregulation of PD-1, PD-L1, CTL antigen-4 (CTLA-4), and multiple(More)
INTRODUCTION ALK gene rearrangements occur in approximately 5% of lung adenocarcinomas (ACAs), leading to anaplastic lymphoma kinase (ALK) overexpression and predicting response to targeted therapy. Fluorescence in situ hybridization (FISH) is the standard procedure for detection of ALK rearrangements in lung ACA but requires specialized equipment and(More)
Patients with germline mutation of succinate dehydrogenase (SDH) subunit genes are prone to develop paraganglioma, gastrointestinal stromal tumor, and rarely renal cell carcinoma (RCC). However, SDH-deficient RCC is not yet widely recognized. We identified such tumors by distinctive morphology and confirmed absence of immunohistochemical staining for SDHB.(More)
INTRODUCTION Break-apart fluorescence in situ hybridization (FISH) is the FDA-approved assay for detecting anaplastic lymphoma kinase (ALK) rearrangements in non-small-cell lung cancer (NSCLC), identifying patients who can gain dramatic benefit from ALK kinase inhibitors. Assay interpretation can be technically challenging, and either splitting of the 5'(More)
Stromal cells within the tumor microenvironment are essential for tumor progression and metastasis. Surprisingly little is known about the factors that drive the transcriptional reprogramming of stromal cells within tumors. We report that the transcriptional regulator heat shock factor 1 (HSF1) is frequently activated in cancer-associated fibroblasts(More)
NUT midline carcinomas (NMCs) comprise a group of highly aggressive tumors that have been reported primarily in the head, neck, and mediastinum of younger individuals. These tumors overexpress the nuclear protein in the testis (NUT), most commonly due to a chromosomal translocation that fuses the NUT gene on chromosome 15 with the BRD4 gene on chromosome(More)
Somatic mutations in FGFR2 are present in 4% to 5% of patients diagnosed with non-small cell lung cancer (NSCLC). Amplification and mutations in FGFR genes have been identified in patients with NSCLCs, and clinical trials are testing the efficacy of anti-FGFR therapies. FGFR2 and other FGFR kinase family gene alterations have been found in both lung(More)
Idiopathic pulmonary fibrosis is characterized by diffuse alveolar damage and severe fibrosis, resulting in a steady worsening of lung function and gas exchange. Because idiopathic pulmonary fibrosis is a generally progressive disorder with highly heterogeneous disease progression, we classified affected patients as either rapid or slow progressors over the(More)
Translocation events are frequent in cancer and may create chimeric fusions or 'regulatory rearrangements' that drive oncogene overexpression. Here we identify super-enhancer translocations that drive overexpression of the oncogenic transcription factor MYB as a recurrent theme in adenoid cystic carcinoma (ACC). Whole-genome sequencing data and chromatin(More)
Copy number variants are a recently discovered source of large-scale genomic diversity present in all individuals. We capitalize on these inherent genomic differences, focusing on deletion polymorphisms, to develop informative fluorescence in situ hybridization probes with the ability to unequivocally distinguish between donor and recipient cells in situ.(More)
