(Submitter supplied) mRNA expression was assayed from bronchial epithelial cell samples from smokers with and without lung cancer. A subset of the samples (2 of the lung cancer samples and 3 of the no cancer samples) were pooled and underwent whole transcriptome sequencing. The goals were to compare whole transcriptome sequencing gene expression levels to gene expression levels derived from these samples run on the Affymetrix HGU133A 2.0 platform.

(Submitter supplied) We have previously shown that gene-expression alterations in cytologically normal appearing bronchial epithelial cells can be used as a biomarker for lung cancer detection in smokers (Whitney et al., BMC Medical Genomics 2015; Silvestri et al., NEJM 2015). In this study, we have established that there are also alterations in bronchial microRNA-expression of smokers with lung cancer. Importantly, the performance of an existing bronchial mRNA-biomarker has been improved by integrating microRNA with mRNA expression.

(Submitter supplied) Gene expression alterations in response to cigarette smoke have been characterized in normal-appearing bronchial epithelium of healthy smokers and it has been suggested that adjacent histologically normal tissue display tumor-associated molecular abnormalities. We sought to delineate the spatial and temporal molecular lung field of injury in smoker early stage non-small cell lung cancer (NSCLC) patients (n=19) who were accrued into a surveillance clinical trial for annual follow-up and bronchoscopies within one year after definitive surgery.

(Submitter supplied) Previous work has shown that lung tumors and normal-appearing adjacent lung tissues share specific abnormalities that may be highly pertinent to the pathogenesis of lung cancer. However, the global and molecular adjacent airway field cancerization in non-small cell lung cancer (NSCLC) has not been characterized before. We sought to understand the transcriptomic architecture of the adjacent airway field canerization, in conjunction with tumors, to gain additional insights into the lung cancer biology and oncogenesis.

(Submitter supplied) One of the most fertile applications of next generation sequencing will be in the field of cancer genomics. Here, we report a high-throughput multi-dimensional sequencing study of primary non-small cell lung adenocarcinoma tumors and adjacent normal tissues of 6 never-smoker Korean female patients. Our data encompass results from exome-seq, RNA-seq, small RNA-seq, and MeDIP-seq. We identified and validated novel genetic aberrations including 47 somatic mutations and 20 fusion transcripts. more...

(Submitter supplied) Epithelial-mesenchymal transition (EMT) has recently been recognized as a key element of cell invasion, migration, metastasis, and drug resistance in several types of cancer, including non-small cell lung cancer (NSCLC). Our aim was to clarify microRNA (miRNA) -related mechanisms underlying EMT followed by acquired resistance to epidermal growth factor receptor tyrosine-kinase inhibitor (EGFR-TKI) in NSCLC. more...

(Submitter supplied) Smoking perpetuates in cytologically-normal airways a molecular “field of injury” that is pertinent to lung cancer and early detection. The evolution of airway field changes prior to lung cancer onset is poorly understood largely due to the long latency of lung malignancy in smokers. Here we studied airway expression changes prior to lung cancer onset in mice with knockout of the Gprc5a gene and tobacco carcinogen (nicotine-specific nitrosamine ketone; NNK) exposure and that develop the most common type of lung cancer, lung adenocarcinoma (LUAD). more...

Samples included tumor and adjacent non-tumor tissues excised from a cohort of 35 patients with Stage I Lung Adenocarcinoma. Candidate prognostic biomarkers were validated by pyrosequencing in independent cohorts.

(Submitter supplied) The major cause of cancer-related deaths in lung cancer patients is commonly attributed to its ability to metastasize to distant organs such as the bone, brain, liver and adrenal glands. The dysregulation in miRNA expression is believed to contribute toward the initiation and progression of metastasis through their capability to regulate target genes. In this study, two NSCLC sub-cell lines possessing opposing migration and invasion properties were established using serial transwell invasion assays, followed by miRNA microarray to obtain the overview of miRNA expression as well as identify important playes in metastasis.
