Project description:Metastasis is a major cause leading to mortality for lung cancer patients. We identified YWHAZ as a potential metastasis-promoting candidate and found that overexpression of YWHAZ promotes lung cancer cell proliferation, anchorage-independent growth, migration, and invasion in vitro, as well as tumorigenesis and metastasis in vivo. It not only increases cell protrusions and branchings but also induces epithelial-mesenchymal transition. Most importantly, YWHAZ protein could prevent £]-catenin from ubiquitination via its association with £]-catenin and enhance slug transcriptional activity which is regulated by £]-catenin/TCF signaling pathway. Moreover, YWHAZ expression was higher in tumors than in adjacent normal tissues in 63 Non-small-cell lung cancer (NSCLC) patients. NSCLC patients with high YWHAZ expressing tumors had shorter overall survival than those with low-expressing tumors. We conclude that YWHAZ play a critical role in promoting NSCLC metastasis. In this investigation, we used a lung cancer invasion cell model to identify the genes involved in cancer progression. YWHAZ is a potential oncogene whose expression is correlated to the survival of patients with breast, prostate and liver cancers. However, the role of YWHAZ in lung caner progression has not been reported, particularly in metastasis. Here, YWHAZ was ectopically expressed in lower invasive lung cancer cell line its impact on colonogenesis, migration and invasiveness was assessed. The underlying mechanism was explored by YWHAZ-expressed transfectants and microarrays and the clinical relevance was evaluated by quantitative RT-PCR.

Project description:S100A4 is a tumor metastasis-promoting protein and drives lung cancer cell invasion and its elevation level is associated with lymphovascular invasion and the decreased overall survival among lung cancer patients. However, how it alters cancer cell metabolism and how metabolic changes affect the invasive and metastatc capacity are unknown.

Project description:Background: JAG-1 is a ligand of Notch signaling and can regulate cell differentiation and proliferation in cancers. Recent studies indicated that JAG1 is a gene associated with cancer progression. Therefore, we investigated the role of JAG1 in lung cancer progression. Methods: The expression of JAG1 was manipulated by overexpression or RNA silencing in several human lung cell lines. The effect of JAG1 on tumorigenesis and invasion was assessed by the cell anchorage-independent growth, cell proliferation, cell migration and invasion assays in vitro as well as metastasis in vivo. The potential downstream genes of JAG1 were identified by oligonucleotide microarrays and quantitative reverse transcription¡Vpolymerase chain reaction (RT-PCR). We further measured JAG1 expression in lung cancer specimens by RT-PCR. Correlation between JAG1 expression and overall survival of lung cancer patients was determined by using the log-rank test and multivariable Cox proportional hazards regression analysis. All statistical tests were two-sided. Results: JAG1 enhanced anchorage-independent growth, cell migration, invasion in the lower invasive cells, CL1-0. JAG1 also increased the capability of migration and invasion in the other two lung cancer cell lines (A549 and NCI-H226). The silencing of JAG1 inhibited migration and invasion activities of the higher invasive cells, CL1-5, by siRNA technology. The invasion-promoting activity of JAG1 was also demonstrated in vivo by using a mouse metastasis model. By microarray analysis, we found that the expression of heat shock 70kDa protein 2 (HSPA2) was activated by JAG1 overexpression and eliminated by JAG1 silencing. Moreover, lung cancer patients with high JAG1 expressing tumors had shorter overall survival than those with low-expressing tumors. Conclusion: JAG1 might be an oncogene which promotes colonogenesis and metastasis, and high JAG1 expression is associated with shorten survival in lung cancer. In this investigation, we used a lung cancer invasion cell model to identify the genes involved in cancer progression. JAG1 is a potential oncogene whose expression is correlated to the survival of patients with breast, prostate and liver cancers. However, the role of JAG1 in lung caner progression has not been reported, particularly in metastasis. Here, JAG1 was ectopically expressed in lower invasive lung cancer cell line its impact on colonogenesis, migration and invasiveness was assessed. The underlying mechanism was explored by JAG1-expressed transfectants and microarrays and the clinical relevance was evaluated by quantitative RT-PCR.

Project description:41 lung adenocarcinoma from never-smokers hybridized on Illumina SNP arrays on 13 HumanCNV370-Quadv3 chips. High-resolution array comparative genomic hybridization analysis of lung adenocarcinoma in 41 never smokers for identification of new minimal common regions (MCR) of gain or loss. The SNP array analysis validated copy-number aberrations and revealed that RB1 and WRN were altered by recurrent copy-neutral loss of heterozygosity.The present study has uncovered new aberrations containing cancer genes. The oncogene FUS is a candidate gene in the 16p region that is frequently gained in never smokers. Multiple genetic pathways defined by gains of MYC, deletions of RB1 and WRN or gains on 7p and 7q are involved in lung adenocarcinoma in never smokers. A 'Cartes d'Identite des Tumeurs' (CIT) project from the French National League Against Cancer (http://cit.ligue-cancer.net) 41 samples hybridized on Illumina SNP arrays.

Project description:G9a is the major mammalian H3-K9 methyltransferase that targets euchromatic regionsand is essential for murine embryogenesis . We demonstrate that G9a is endowed with methyltransferase activity to concomitantly repress the downstream effector Ep-CAM, thereby promoting the invasion step of the invasion-metastasis cascade. We used microarrays to detail the G9a regulated gene expression underlying invasion-metastasis cascade and identified distinct classes of up-regulated genes during this process. Lung adenocarcinoma cells with G9a knockdown or overexpression were selected for RNA extraction and hybridization on Affymetrix microarrays.
