Transcription profiling by array on 123 paired tumor and non-tumor tissue samples from patients with non-small cell lung carcinoma to gain a systems biology insight into the current clinical classification

ABSTRACT: Non-small cell lung cancer (NSCLC), a leading cause of cancer deaths, represents a heterogeneous group of neoplasms, mostly comprising squamous cell carcinoma (SCC), adenocarcinoma (AC) and large-cell carcinoma (LCC). The aim of this study was to gain a systems biology insight into the current clinical classification. Patients and Methods: Comparative genomic hybridization followed by mutational analysis, gene expression and miRNA microarray profiling were performed on 123 paired tumor and non-tumor tissue samples from patients with NSCLC. Using integrated systems biology approaches, we sought to find out if combining data types from different levels of biology would improve clinical assessment of NSCLC. Results: At both DNA, RNA and miRNA levels we could identify molecular markers that discriminated significantly between the various clinicopathological entities of NSCLC. Conclusions: We report proofs of distinct molecular profiles that contribute to distinguishing NSCLC tumor subtypes even in small biopsies. The Gene expression experiments have been made in dual color and dye_swap with Agilent human Human Genome Exon 244K arrays (custom design 14891, from commercial 4x44K (design 014850 plus 195000 oligo - 1 per exon- defined with RefSeq hg18 and 1840 probes from viral transcripts). Note date of surgery is the date of the sample was frozen.

Project description:Docetaxel is used as a standard treatment in patients with metastatic castration-resistant prostate cancer. However, a large subset of patients develops resistance by mechanisms that remain largely unknown. It is thus important to define the relevant pathways implicated in docetaxel-resistance and validate predictive biomarkers that will allow approaches of personalized treatment. In this aim, we established resistant IGR-CaP1 prostate cancer cell lines to different doses of docetaxel (IGR-CaP1-R cell lines) and investigated gene expression profiles by microarray analyses. We generated a signature of 112 genes potentially implicated in docetaxel-resistance whose expression is highly modified (Fold change M-bM-^IM-% 5). Among these genes, significant modification of expression was observed among cell cycle components in the resistant cells. Hence, we focused on the role of the cell cycle regulator LZTS1 located on chromosome 8p which was under-expressed in all our docetaxel-resistant models. LZTS1 extinction was confirmed at the RNA and protein levels. DNA methylation analysis revealed a stretch of 20 highly methylated CpGs in the region encompassing the exon 1 of LZTS1 promoter in the docetaxel-resistant cells suggesting the existence of an epigenetic regulation of LZTS1 expression in the resistant cells. By using siRNA strategy, we found evidence that LZTS1 plays an important role in the acquisition of the resistant phenotype. In addition, immunohistochemical staining showed that LZTS1 protein was absent or down-regulated in 33% of diagnostic biopsies obtained in patients with metastatic castration-resistant prostate cancer. This heterogeneous labeling suggests that LZTS1 might constitute a predictive biomarker of response to docetaxel chemotherapy. Furthermore, as Cdc25C is a LZTS1 partner in the mitosis regulation, we observed that targeting of Cdc25C with the pharmacological Cdc25C inhibitor NSC 663284 specifically killed the docetaxel-resistant cells. These results strongly suggest that Cdc25C plays a role in docetaxel resistance and that Cdc25C might be a therapeutic target to overcome docetaxel resistance. Altogether our findings identify an important role of LZTS1 in developing docetaxel resistance in prostate cancer through its role in regulating phosphatase Cdc25C. The set of gene expression with 4x44K Agilent ( design 014850) correspond to 6 doses of docetaxel 2?5 to 200 ug/ml) in dual color and dye-swap versus the IGR-Cap1 cell line without docetaxel.

Project description:In most mammalian species, a critical step of placental development is the fusion of trophoblast cell into a multinucleated syncytiotrophoblast layer, which separates the fetal and maternal blood circulations. Advancement in understanding this process came from the identification of two pairs of envelope genes of retroviral origin, independently acquired by the human (syncytin-1 and M-^V2) and mouse (syncytin-A and M-^VB) genomes, specifically expressed in the placenta and with in vitro cell-cell fusion activity. We previously showed that syncytin-A is involved in the formation of one of the two syncytiotrophoblast layer of the mouse placenta -ST-I , facing the maternal lacuna- with syncytin-A null embryos dying at mid-gestation, and their placenta disclosing impaired formation of the ST-I layer. Here by generating syncytin-B KO mice, we demonstrated that syncytin-B null placenta have defects in formation of the syncytiotrophoblast layer-II facing the fetal blood vessels, with refined electron microscopy analyses showing evidence of unfused apposed cells. Lack of trophoblast fusion is associated with signs of trophoblast degeneration and with formation of huge maternal blood lacuna, ultimately disrupting the architecture of the labyrinth layer. These alterations did not result in complete abortion of syncytin-B null embryos, at variance with the syncytin-A KO phenotype, but in a reduced proportion of homozygous syncytin-B knockout individuals at birth, with evidence of late-onset embryonic growth retardation. Double knockout mice experiments demonstrate a premature death of syncytin-A null embryos if syncytin-B is deleted, thus strongly suggesting cooperative involvement of both syncytiotrophoblast layer-I and layer-II for the structural and functional integrity of the maternofetal interface and exchanges. Finally, a microarray analysis of wild-type and syncytin-B null placenta transcripts disclosed alterations in gene expression level for only a very limited number of genes, with the largest change (a 7-fold induction in the syncytin-B null placenta) observed for the connexin-30 gene. Immunohistochemistry further localized the connexin-30 protein in the labyrinth zone of mutant placenta, at the level of the fetomaternal interface. It is proposed that this might correspond to a compensatory process whereby disruption of syncytialization in syncytin-B knockout placenta is counteracted by an enhanced, gap junction mediated, cell-cell communication. These data demonstrate that syncytin-B is required for ST-II syncytial differentiation and the functional integrity of the labyrinth. Altogether, these findings definitively demonstrate that the two endogenous retroviral syncytin-A and -B Env genes contribute independently to the formation of the two syncytiotrophoblast layers during placenta formation, and provide additional insights into the subtle mechanisms of syncytiotrophoblast differentiation in the mouse. Experimental design: Placenta RNA of embryos homozygous for the syncytin-B deletion (SynB-/-) were compared to placental RNA of wild-type embryos (SynB+/+) of the same litter. Two stages of gestation, day 12 and d14, were analyzed. At day 12, 3 litters were obtained; for two of them, the RNAs were analyzed individually, and for the third one, placenta RNAs of the wild-type genotype were pooled. At day 14, one litter was obtained; RNA samples with the same genotype were pooled

Project description:Radiotherapy has a critical role in the treatment of small cell lung cancer (SCLC). Effectiveness of radiation in SCLC remains limited as resistance results from defects in apoptosis. In the current study, we investigated whether using a Bcl-2/Bcl-XL inhibitor S44563 can enhance radiosensitivity of SCLC cells in vitro and in vivo. In vitro studies confirmed that S44563 induce apoptosis in SCLC cells by inducing hallmarks of apoptosis (cleaved caspase-3, sub-G1 fraction induction and induction of the mitochondrial caspase activation pathway). S44563 markedly enhanced sensitivity of H146 cells and H69 cells to radiation in clonogenic assay. In addition, the combination S44563 and cisplatin-based chemo-radiation showed a dramatic tumor growth delay and increased overall survival in mouse xenograft models. In vitro experiments demonstrated a greater induction of apoptosis (sub-G1 fraction and cleaved caspase-3) with the combination as well as in vivo caspase-3 immunostaining. This positive interaction between S44563 and radiation was greater when S44563 was given after the completion of the radiation, which may be explained by the radiation-induced over expression of anti-apoptotic proteins (Bcl-2 and Bcl-XL) through the NF-?B pathway activation. Taken together, these data underline the critical role of sequence administration of targeted therapies with conventional therapies. SCLC cells which survive to IR highly rely on the induction of anti apoptotic proteins in part through NF- ?B activation for their survival yielding to the concept of 'contextual oncogene addiction' to the Bcl-2/Bcl-XL pathway providing rational for targeting survival pathways to potentiate IR. For transcriptome analysis, 106 cells were seeded in T25 flasks, allowed to growth for 24 h, and then left untreated or treated with 2 Gy radiation. After 24 hours, cells were harvested, lysed for the extraction of RNA, and processed to analyze gene expression.The design of this study consists to 6 hybridizations in dual color with Agilent Human Genome 4x44K (design 014850). The reference is always the untreated condition.
