(Submitter supplied) The NKX2-1 transcription factor, a regulator of normal lung development, is the most significantly amplified gene in human lung adenocarcinoma. To better understand how genomic alterations of NKX2-1 drive tumorigenesis, we generated an expression signature associated with NKX2-1 amplification in human lung adenocarcinoma, and analyzed DNA binding sites of NKX2-1 by genome-wide chromatin immunoprecipitation from NKX2-1-amplified human lung adenocarcinoma cell lines. more...

(Submitter supplied) Despite the high prevalence and poor outcome of patients with metastatic lung cancer, the mechanisms of tumour progression and metastasis remain largely uncharacterized. We modelled human lung adenocarcinoma, which frequently harbours activating point mutations in KRAS1 and inactivation of the p53-pathway2, using conditional alleles in mice3-5. Lentiviral-mediated somatic activation of oncogenic Kras and deletion of p53 in the lung epithelial cells of KrasLSL-G12D/+;p53flox/flox mice initiates lung adenocarcinoma development4. more...

(Submitter supplied) Tissue-specific differentiation programs become dysregulated during cancer evolution. The transcription factor Nkx2-1 is a master regulator of pulmonary differentiation that is downregulated in poorly differentiated lung adenocarcinoma. Here we use conditional murine genetics to study the fate of lung epithelial cells upon loss of their master cell fate regulator. Nkx2-1 deletion in normal and neoplastic lung causes not only loss of pulmonary identity but also gastric transdifferentiation. more...

(Submitter supplied) Nkx2.1 is a critical regulator of mammalian lung development. It is expressed in epithelial cells at the initiation of lung organogenesis, becoming progressively restricted during development to bronchiolar and alveolar type II epithelial cells. In humans, it is a common marker of carcinomas of lung and thyroid origin and is highly amplified in 10-15% of lung adenocarcinomas. Despite its key role in development and disease only a few genes directly regulated by Nkx2.1 are known. more...

(Submitter supplied) Thyroid transcription factor-1 (TTF-1), also known as NKX2-1, plays a role as a lineage-survival oncogene in lung adenocarcinoma with double-edged sword characteristics. Although previous studies steadily accumulated evidence for roles of TTF-1 in the transcriptional regulation of protein-coding genes, very little is known about its regulatory relationship with miRNAs. In this study, we have identified miR-532-5p as a novel transcriptional target of TTF-1 by an integrative approach, which was designed to extract maximal information from expression profiles of both patient tumors in vivo and TTF-1-inducible cell lines in vitro. more...

(Submitter supplied) A transcription factor Nkx2-1 (also known as TTF-1) regulates the expression of different sets of genes. Gene expression analysis was performed using mRNAs from Nkx2-1-induced A549 cells compared to that from the control A549 cells. We used microarrays to detail the global program of gene expression controlled by Nkx2-1 and identified distinct classes of up-regulated and down-regulated genes.

(Submitter supplied) Transgenic mice (Scgb1a1-rtTA/[tetO]-KRAS.G12D/Nkx2-1+/-) develop mucinous lung tumors. Gene expression analysis was performed using mRNAs from the whole lungs of the mice compared to that of the control mice. We used microarrays to detail the global program of gene expression underlying development of mucinous lung tumors and identified distinct classes of up-regulated genes during this process.

(Submitter supplied) Profound changes in cancer cell identity can alter malignant potential and therapeutic response. Loss of the pulmonary lineage specifier NKX2-1 augments the growth of KRAS-driven lung adenocarcinoma and causes pulmonary to gastric transdifferentiation. Here we show that the transcription factors FoxA1 and FoxA2 are required for initiation of mucinous NKX2-1-negative lung adenocarcinomas in the mouse and for activation of their gastric differentiation program. more...

(Submitter supplied) For a number of clinical and biological reasons, the accurate classification of non-small cell lung carcinoma (NSCLC) into adenocarcinoma (ADC) and squamous cell carcinoma (SCC) is essential. DNA-based tests, which are not currently used, are more robust when applied to formalin-fixed paraffin-embedded tissues. To develop a molecular-based classification of NSCLC based on genome wide copy number variations (CNVs), the corresponding TCGA, SPORE and CANARY patient datasets were used as training and independent validation data. more...

(Submitter supplied) Purpose Prospectively identifying who will benefit from adjuvant chemotherapy (ACT) would improve clinical decisions for individual non-small-cell lung cancer (NSCLC) patients. Most current molecular signatures for lung cancer are prognostic only and provide limited information with regard to the functional importance of the genes selected. In this study, we aim to develop and validate a functional gene set that predicts the clinical benefit of ACT in NSCLC. more...

Methods: Patients with pre-treated NSCLC, ECOG performance status (PS) 0-2, consented to biopsies to test for biomarker assessment. Sorafenib was given at 400 mg orally twice daily until tumor progression or an unacceptable toxicity. Tumor evaluations were performed at baseline and every 8 weeks. more...
