Hypoxia-driven alterations in the B16 melanoma cell transcriptome account for a higher metastatic potential

ABSTRACT: Hypoxia-driven alterations in the B16 melanoma cell transcriptome account for a higher metastatic potential: evidence for a role of Ero1L We analyzed transcriptomic adaptations to hypoxia/reoxygenation in B16 melanoma cells. By Ero1L over- and down-expression in vivo, we identified this ER oxidase as an actor of tumor growth and metastasis take.

Expression data from mouse B16-F10 cells exposed to hypoxic conditions in vitro.

Project description:Analysis of gene expression profile of B16-F10 murine melanoma cells exposed to hypoxic conditions (1% oxygen) or hypoxia mimicry (cobalt chloride) for 24 hours. Gene expression profiles were analyzed using MG-U74Av2 oligonucleotide microarrays. Data analysis revealed 2541 probesets (FDR<5%) for 1% oxygen experiment and 364 probesets (FDR<5%) for cobalt chloride, that showed differences in expression levels. Analysis of hypoxia-regulated genes (1% O2) by stringent Family-Wise Error Rate estimation indicated 454 significantly changed transcripts (p<0.05). The most upregulated genes were Lgals3, Selenbp1, Nppb (more than ten-fold increase). Both hypoxia and hypoxia-mimicry induced HIF-1 regulated genes. However, unsupervised analysis (Singular Value Decomposition) revealed distinct differences between gene expression induced by these two experimental conditions. We investigated transcriptional activity of B16-F10 murine melanoma cells cultured for 24h under hypoxic (nominal 1% oxygen; 9 experimental samples and 6 controls) and hypoxia-mimicking conditions (cobalt chloride, 100 M-NM-<M or 200 M-NM-<M, 2 samples each and 2 controls).

B16 versus B16B1

Project description:Analysis of gene expression patterns in cancer improved the understanding the mechanisms underlying the process of metastatic progression. Recent studies have attributed an important role to B-1 cells, a subset of B lymphocytes, in melanoma progression. It was already demonstrated that in vitro interaction between B16 melanoma cells and B-1 lymphocytes induced increase in metastatic potential of B16 lineage. In this study we used a microarray approach to assess gene expression profile in B16 melanoma cells after contacting B-1 lymphocytes (B16B1).

Gene Expression patterns in mouse B16-OVA melanoma tumors

Project description:This laboratory focuses on selectin mediated recruitment during adoptive immunotherapy for metastatic cancer. This study seeks to determine changes in the expression levels of Fucosyltransferases, Selectins, and cytokines in normal and inflamed mouse skin, melanoma tumor tissue of different sizes, and tumor cells grown in culture. Since the ability to treat the tumor effectively is directly related to the size of the tumor, differences in glyco-expression patterns may be of interest. In this study, five groups were hybridized and analyzed using the GLYCOv2 array. Each group was analyzed in triplicate. The groups were: Normal mouse skin, normal mouse skin inflamed by treatment with Oxazolone, B16-OVA melanoma tissue from 6 day tumors, B16-OVA melanoma tissue from 11 day tumors, and B16-OVA grown in cell culture.
