Transcriptome analysis of isolated stormal cells and tumor epithelial cells in mouse lung cancer by RNA-Seq

ABSTRACT: We sequenced mRNA from individual stormal cells (Macrophages, Monocytes, and Neutrophils) and tumor epithelial cells from KrasG12dD; p53-/- murine lung cancer model and WT control mouse to compare gene expressio profiles of lung cancer stroma and tumor cells to their counterparts of WT lugns. The tumor was generated by injecting HKP1 lung cancer cell line, which was driven by KrasG12D activation and loss of p53, via tail vein. The cells were sorted by their specific surface markers at day 20-25 after orthortopic lung cancer formation.

Emerging studies have begun to demonstrate that reprogrammed stromal cells play pivotal roles in tumor growth, metastasis, and resistance to therapy. However, the contribution of stromal cells to non-small-cell lung cancer (NSCLC) has remained underexplored. We used an orthotopic model of Kras-driven NSCLC to systematically dissect the contribution of specific hematopoietic stromal cells in lung cancer.

Detection of oncoantigens suitable for lung cancer vaccination

Project description:The lung cancer tumor K-rasLA1/ p53 R172HDeltag mouse model was used to identify genes associated to the tumor mass increase in lungs. Those genes were then ranked on the basis of their oncogenic potential using a metadataset encompassing 695 human lung adenocarcinomas and ranking them on the basis of their expression in normal tissues. The genes characterized by the higher oncogenic potential combined to a low expression in normal tissues were selected as putative targets for preclinical studies on lung cancer vaccination. Two prototypic situations (WT, and MUT) were examined using Exon arrays over a three-points time course (10, 20, and 30 weeks old animals), for each time point two/three male and female animals were used. A total of 30 mouse Exon 1.0 arrays were hybridized.

Transcriptional profiling of lung tumour cell lines with distinct p53 mutations in the absence or presence of WT p53

Project description:Microarray expression data generated to determine the impact of defined p53 mutations on lung cancer cell phenotypes, and on the tumour supressive responses induced by WT p53 restoration. In murine models of lung cancer, the therapeutic benefit of WT p53 restoration has been demonstrated in p53-deficient tumours (Juntilla et al, 2010; Feldser et al, 2010). However, it remains unknown if the restoration of WT p53 function is beneficial in p53 mutant tumours. Thus, to determine the impact of p53-targeted therapy in mutant p53 lung cancer, we analysed cells from murine lung tumours of distinct p53 genotypes. Utilising the well characterised p53-ER allele (Christophorou et al, 2005; Martins et al, 2006; Juntilla et al, 2010) we carried out transcriptional profiling of KrasG12D/+ cell lines isolated from advanced lung tumours with defined p53 status: p53Fx/ER (null), p53R270H/ER and p53R172H/ER in the absence (p53 WT OFF) or presence (p53 WT ON) of 4-hydroxytamoxifen (4-OHT). The temporal specificity of p53-ER restoration allowed us to utilised two timepoints to determine both the immediate (2hr) and sustained (8hr) impact of WT p53 function.

Gene expression signatures for murine alveolar type II lung epithelial cells after tumor bearing

Project description:To determine the influence of primary tumors on pre-metastatic lungs, we have employed whole genome microarray expression profiling as a discovery platform to identify gene signatures of alveolar type II epithelial cells (AT-II) in TLR3 deficient mice (Tlr3-/-) and wide-type (WT) littermates with tumor bearing. We subcutaneously inoculated Tlr3-/- and WT mice with Lewis lung carcinoma (LLC). Two weeks later, lung tissues from Tlr3-/- and WT mice were dissociated and AT-II cells were sorted. AT-II cells from mice without tumor bearing were set as controls.

Expression data from human fetal lung normal diploid fibroblasts

Project description:The interaction between cancer and stroma plays a key role in tumor progression. Inactivation of p53 is often observed in stromal cells surrounding in cancer, suggesting that p53 in fibroblasts is involved in tumor progression. To elucidate the mechanism by which p53 loss in fibroblasts effect on proliferation and invasiveness of cancer cells, we performed comprehensive expression profiling analyses between p53 knockdown and control fibroblasts using GeneChip Human Genome U133 plus 2.0 arrays. Intact human fetal lung normal diploid fibroblasts TIG-7 cells and TIG-7 cells infected with lentiviruses for the expression of shRNA against p53 were used for RNA extraction and hybridization on Affymetrix microarrays.

The lung-enriched p53 mutants V157F and R158L/P regulate a novel transcriptome in lung cancer

Project description:Lung cancer is the leading cause of cancer-related deaths in the US, and alterations in the tumor suppressor gene TP53 are the most frequent somatic mutation among all histologic subtypes of lung cancer. Mutations in TP53 frequently result in a protein that exhibits not only loss of tumor suppressor capability but also gain of oncogenic function (GOF). The canonical p53 hotspot mutants R175H and R273H, for example, confer upon tumors a metastatic phenotype in murine models of mutant p53. To our knowledge, GOF phenotypes of the less often studied V157, R158, and A159 mutants – which occur with higher frequency in lung cancer compared with other solid tumors – have not been defined. In this study, we aimed to define whether the lung mutants are simply equivalent to full loss of the p53 locus, or whether they additionally acquire the ability to drive new downstream effector pathways. Using a publicly available human lung cancer dataset, we characterized patients with V157, R158, and A159 p53 mutations. Additionally, we show here that cell lines with mutant p53-V157F, p53-R158L, and p53-R158P exhibit a loss of expression of canonical wildtype p53 target genes. Furthermore, these lung-enriched p53 mutants regulate genes not previously linked to p53 function including PLAU. Paradoxically, mutant p53 represses genes associated with increased cell viability, migration, and invasion. These findings collectively represent the first demonstration that lung-enriched p53 mutations at V157 and R158 regulate a novel transcriptome in human lung cancer cells and may confer de novo function.

Expression data from immortalized human lung small airway epithelial cells

Project description:In lung cancer progression, p53 mutations are more often observed in invasive tumors than in non-invasive tumors, suggesting that p53 is involved in tumor invasion and metastasis. To understand the nature of p53 function as a tumor suppressor, it is crucial to elucidate the detailed mechanism of the alteration in epithelial cells, the main origin of solid tumors, following p53 inactivation. To elucidate the mechanism by which p53 loss enhances invasive and motile activities in human lung small airway epithelial cells (SAECs), we performed comprehensive expression profiling analyses between p53 knockdown and control cells using GeneChip Human Genome U133 plus 2.0 arrays.
