Expression data from lung SCC treated with DMSO and PXD101

ABSTRACT: We used microarrays to detail the global programme of gene expression in lung SCC cells treated with belinostat, a pan-HDAC inhibitor. The primary focus of this work is to investigate the efficacy of belinostat on lung SCC cells. Our phosphoproteomic profiling analyses revealed the downregulation of MAPK signaling pathway upon drug treatment, together with the induction of apoptosis. While HDAC inhibition generally affects transcription, the mechanism of SOS/MAPK downregulation was therefore proposed to be affected at the transcriptomic level. However, genes related to MAPK pathway were not significantly regulated upon belinostat treatment, whereas ubiquitin-proteasome gene signature was affected. This supports an indirect mechanism of epigenetic regulation on MAPK signaling that should be explored further.

Gene expression alteration by different cell lines derived from lung SCC of IKKM-NM-1 mutant mice

Project description:In this study, we found that kinase-dead IKKM-NM-1 knockin (KAL) mice. develop spontaneous lung squamous cell carcinomas (SCCs) associated with IKKM-NM-1 downregulation and marked pulmonary inflammation.KKM-NM-1 downregulation dysregulates the expression of multiple oncogenes and tumor suppressors in K5+ lung epithelial cells. The mutant macrophages increase inflammatory responses and oxidative stress to promote DNA damage in IKKM-NM-1-mutant K5+ lung epithelial cells, which further dysregulate the levels of multiple oncogenes, tumor suppressors, and stem cell genes, thereby promoting the IKKM-NM-1lowK5+p63hi cell transition to tumor cells in L-IkkM-NM-1KA/KA lungs. To further investigate the underlying mechanisms by which the lung SCC development, we generated two cell lines, named as S1 and S2 individually, which were derived from KAL lung SCC. The S1 cells express high level of Sca1 and exhibit tumorigenic phenotype, while the S2 cells express low level of Sca1 and exhibit less tumorigenic phenotype. The aim of this microarray assay is to identify differentially expressed genes between S1 and S2 cells, which may highlight the important genes or pathways involved in inflammation-associated lung SCC carcinogenesis. There were two cell lines were used to perform Gene chip assay with Affymetrix. The two cell lines, named as S1 and S2 individually, were derived from KAL lung SCC. The S1 cells express high level of Sca1 and exhibit tumorigenic phenotype, while the S2 cells express low level of Sca1 and exhibit less tumorigenic phenotype.

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.

ArrayCGH mapping of chromosome 3 aberrations 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. 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 Profiling of 26 advanced (stage III) lung SCC. Replicates : each tumor sample is hybridized together with a normal dna sample to one microarray. Each microarray contain 3 replicates per BAC clone.

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.
