ArrayCGH mapping of chromosome 3 aberrations in lung Squamous Cell Carcinoma (SCC)

ABSTRACT: To prospectively identify new oncogenes implicated in lung Squamous Cell Carcinoma pathogenesis, we investigated chromosome 3 aberrations in advanced tumours using arrayCGH. These aberrations are indeed among the most frequent aberrations in lung SCC and correlate with SCC patient's poor prognosis. We precisely map regions of recurrent losses at 3p and gains at 3q25-qter in a series of lung SCC. We moreover uncover 3q26.3-q27 high level amplifications in 20% of tumours. Keywords: ArrayCGH, Lung Squamous Cell Carcinoma, 3q26.3, SOX2

ArrayCGH mapping of the recurrent 3q26.3-q27 amplifications in lung Squamous Cell Carcinoma (SCC)

Project description:To prospectively identify new oncogenes implicated in lung Squamous Cell Carcinoma pathogenesis, we investigated chromosome 3 aberrations in advanced tumours using arrayCGH. Chromosome 3 aberrations are indeed among the most frequent alterations in lung SCC and correlate with SCC patient's poor prognosis. We have precisely mapped regions of recurrent losses at 3p and gains at 3q25-qter in a series of lung SCC (GSE14859) amd moreover uncover 3q26.3-q27 high level amplifications in 20% of tumours. These amplicons were precisely mapped in these tumors using arraCGH with a 3q26.3 dedicated tiling array. Keywords : ArrayCGH, lung Squamous Cell Carcinoma, 3q26.3, SOX2 Keywords: ArrayCGH

The Role of JNK1/2 in Mouse Lung Squamous Cell Carcinoma (SCC) Development

Project description:Lung cancer is the leading cause of cancer death in USA. Squamous Cell Carcinoma (SCC) is one of the subtypes of lung cancer. It is still largely unknown which genes or pathways regulate lung SCC development. Recently, we found JNK1/2 pathway was inhibited in mouse lung SCC induced by double ablation of Pten and Lkb1 in mouse lung epithelial cells. Now we aim to identify a genome-wide molecular signature of JNK1/2 signaling in mouse squamous cell carcinoma cells and determine pathways that transduce JNK1/2 signaling.

LSCC

Project description:The basaloid carcinoma (pure) and the (mixed) basalod variant of lung squamous cell carcinoma (SCC) have a dismal prognosis but their underlying specific molecular characteristics remain obscure and no therapy has proven to be efficient. In order to assess their molecular specificity among other lung squamous cell carcinomas we analysed DNA copy number aberrations and mRNA expression pangenomic profiles of 93 SCC, including 42 basaloid samples (24 pure, 18 mixed).

The Role of Lkb1 in Mouse Lung Squamous Cell Carcinoma (SCC) Development

Project description:Lung cancer, majorly divided into non-small cell lung cancer (80-85%) and small cell lung cancer (15-20%), is the leading cause of cancer death in USA. Squamous Cell Carcinoma (SCC) is one of major subtypes of non-small cell lung cancer. Although genomic analysis of tumors from SSC patients have identified frequently mutated genes in these tumors, it’s still largely unknown which genes determine SCC development. Now we found that ablation of alone Lkb1 could induce SCC around 12 months of age. Therefore, transcriptome analysis of lung SCC of CCSPiCreLkb1f/f mice will help us understand how Lkb1 regulates the development of lung SCC.

The expression profile of lung sqaumous cell carcinoma (SCC) and adenosquamous carcninoma (ASC) of CCSPiCreLkb1f/fPtenf/f mice

Project description:Lung cancer, majorly divided into non-small cell lung cancer (80-85%) and small cell lung cancer (15-20%), is the leading cause of cancer death in USA. Squamous Cell Carcinoma (SCC) is one of major subtypes of non-small cell lung cancer. Although genomic analysis of tumors from SSC patients have identified frequently mutated genes in these tumors, it’s still largely unknown which genes determine SCC development. Now we found that ablation of Lkb1 and Pten could induce SCC and ASC around 3 months of age. Therefore, transcriptome analysis of lung SCC and ASC of CCSPiCreLkb1f/f mice will help us understand how Lkb1 and Pten regulate the development of lung SCC and ASC.
