Project description:Comparison of transcriptomic profile of the murine B16F1-GFP-M melanoma cells with the derived dormant B16F1-GFP-D, B16F1-GFP-DB#1, B16F1-GFP-DB#2, B16F1-GFP-DB#3 melanoma cells

Project description:Cancer patients after successful therapy contain nested in their organs and/or circulating in the systemic fluids tumor cells that remain asymptomatic for an extended period of time. They stay dormant with no apparent immediate potential to develop into a clinically manifested tumor until activated by yet not well defined mechanisms. We previously developed tumor dormancy model of murine melanoma, a cancer with a high potential of phenotype plasticity to adapt to micro-environmental changes, in which to investigate cellular quiescence and related factors as a potential mechanism of tumour dormancy. In this study, to explore molecular mechanism responsible for cellular dormancy, we performed a comparative transcriptome analysis of dormant B16F1-GFP-D and derived dormant brain metastasis (DB) with maternal B16F1-GFP-M cells.

Peroxisome proliferator-activated receptor-gamma (PPARgamma) is a nuclear receptor highly expressed by colonic epithelial cells. It plays a key role in gut homeostasis and metabolism regulation. We previously showed that PPARgamma has a role in the action of aminosalycilates (5-ASA), one of the oldest anti-inflammatory agents used in the treatment of inflammatory bowel disease. These data have prompted us to develop novel analogues of 5-ASA with greater PPARgamma-activating properties (GED). The various PPARgamma ligands appear to have some markedly different effects, some of which can induce adverse effects. The transcriptomic profiles induced by various families of PPARgamma ligands are very poorly known and especially in intestinal epithelial cells. Hence, the objectives of the present project are to compare the gene expression profile induced by GED, 5-ASA, and pioglitazone in Caco-2 cells, in order to better understand these compounds’ modes of action, to discover potential new PPARgamma target genes in intestinal epithelial cells and to explain the efficacy difference between GED and 5-ASA.

Project description:B16F1 cells are a good model to study cell motility and cytoskeletal organization. In our lab, a combination of microscopy and gene silencing was used to approach the problem. Having gene expression profiles for B16F1 would facilitate and support subsequent gene silencing by RNAi as well as potentially identify new molecular players. We used microarrays to detail the expression profiles in cells cultured in regular conditions. These profile will serve as a reference point for further studies. Experiment Overall Design: Three biological replicats of control untreated B16F1 mouse melanoma cells were processed on mouse GeneChip arrays 430A. Reliability, variability, and reprodusibility of data generated by microarrays were addressed.

Project description:The objective of this study was to obtain expression profiles of proliferative T-HEp3-GFP and dormant D-HEp3-GFP cells after one week in vivo. The second objective was find tumor cells quiescence associated genes in dormant D-HEp3 cells that are only quiescent when injected in vivo. In this case we compared cells one week growing vs. dormant for the indicated cells in chick embryo CAMs. After one week 5 embryos per cell line carrying the indicated cells were isolated, tumors collagenased as described below and sorted for GFP-high cells usig a MoFlo machine. The sorted cells > 5x10^4 were used to extract RNA and the pure RNA was used to perform expression profiling using the Affymetrix HG-u133plus2 arrays. Because of the low amount of D-HEp3 (dormant) cells recovered all tumor cells from the dormant nodules were pooled. The same was done for proliferative-sorted T-HEp3-GFP cells to allow comparisons. Arrays were performed in triplicate. 5 T-HEp3-GFP tumors and 5 D-HEp3-GFP nodules were processed for preparation of single cells suspensions, RNA extracted and then pools of T-HEp3-GFP and D-HEp3-GFP sorted cells were analyzed in triplicate arrays

Project description:Background: We previously demonstrated that B16F1 melanoma tumors growing in syngeneic germline-deleted TNFR1,2 -/- mice were more sensitive to ionizing radiation (IR) compared to tumors growing in C57BL/6 wild-type mice; however, the mechanisms linked to this difference in radiosensitivity are not fully understood. Methodology/ Principal Findings: We used DNA microarrays to identify alterations in the expression of functional gene clusters associated with the radiosensitization of B16F1 tumors growing in TNFR1,2 -/- mice. At the basal level, disruption of host stromal TNFα signaling resulted in the over-expression of tumor genes involved in extracellular matrix remodeling and angiogenesis. Phenotypically, these tumors exhibited a reduced vascular density, which induced the expression of oxidative stress signaling pathways and increased levels of tissue hypoxia and necrosis. These alterations were paralleled by the suppression of genes involved in chromosomal stability and key effectors of the ATM-dependent/ non-homologous end-joining pathways including phosphorylated-ATM, BRCA1, and RAD51, which resulted in greater DNA double-strand breaks and caspase 3 activation following IR treatment. Conclusions/ Significance: Taken together, these results demonstrate that disruption of TNFα signaling in the host stroma mediates transcriptional and phenotypic changes in tumors which may alter tumor radiosensitivity. These results suggest a critical role for TNFα in the maintenance of tumor-associated vasculature and radioresistance. They also indicate that TNFα signaling blockade in stromal cells may represent a strategy for tumor radiosensitization. To investigate the genes associated with the radiosensitization of B16F1 melanoma tumors in the context of disrupted stromal TNFα signaling, we performed expression profiling of B16F1 tumors grown in syngeneic TNFR 1, 2 -/- and wild-type C57BL/6 mice. Tumors were lysed to collect total RNA, pooled by treatment group according to total RNA level, and analyzed in duplicates with Affymetrix GeneChip® Mouse Genome 430 2.0 Arrays.

Project description:Analysis of bone marrow derived macrophages (BMDM) incubated with dexamethasone&IL4 (Dexa+IL4), B16F1 tumor conditioned medium (cmB16), and B16F1 tumor conditioned medium supplemented with dexamethasone&IL4 (cmB16+dexa+IL4). Results allow detection of genes that require synergistic stimulation of tumor factors and Th2 cytokines.
