Project description:Human melanoma MeWo cells and their respective LM2 metastatic derivatives, generated through in vivo selection, were transcriptomically profiled in the context of miR-199a and miR-1908 gain- and loss-of-function in order to identify putative target genes for these miRNAs, MeWo cells and their respective LM2 metastatic derivatives in the context of miR-199a and miR-1908 gain- and loss-of-function

Project description:To identify the genes targeted by miR-199a-3p in metastatic melanoma cells, we compared global gene expression in miR-199a-3p vs control miR transiently transfected cells by transcriptomic microarrays.
Project description:This SuperSeries is composed of the following subset Series: GSE23904: Gene expression profilling of poorly metastatic MDA cells and highly metastatic LM2 cells. GSE23905: miR-126 over-expression in highly metastatic LM2 breast cancer cells. Refer to individual Series
Project description:Spontaneous cell fusion of MDA-MB-231 bone-metastatic subline Bm (i.e., SCP2) and lung metastatic subline Lm (i.e., LM2) gave rise to hybrid lines BLm-FACS or BLm-DRUG, as well as its single clones (#8, #12, #18). The hybrids acquired the metastasis tropisms from both parental cells. Expression profiles of the parental cells, the hybrids and several previously characterized MDA-MB-231 metastatic derivatives were compared. Hierarchical clustering showed the hybrids assimilated the organ-specific metastasis gene signatures from both parental cells. Keywords: Cell type comparison
Project description:miR-126 were over-expressed using the miR-Vec system in highly metastatic LM2 cells. The LM2 cell line are described in detail in Minn et al. Nature 2005 This approach was used to conduct an unbiased search for specific miR-126 target genes in breast cancer cells.

Project description:Parental MeWo cells sensitive to chemotherapeutic drugs Etoposide, Fotemustine, Vindesine and Cisplatin, as well as their resistant derivatives, were analyzed for expression of potential mediators of resistance using genome-wide expression profiling.
Project description:The LM2 derivative cell line is described in Minn et al. Nature 2005. The LM1a derivative cell line is described in Tavazoie et al. Nature 2008. Tumorigenic-enriched (TE) and lung-metastatic (LM) derivatives and their respective parental populations, from the breast cancer MDA-MB-231 and CN34 cell lines were transcriptomically compared in order to identify candidate regulators of breast cancer tumor re-initiation.
Project description:Spontaneous cell fusion of MDA-MB-231 bone-metastatic subline Bm (i.e., SCP2) and lung metastatic subline Lm (i.e., LM2) gave rise to hybrid lines BLm-FACS or BLm-DRUG, as well as its single clones (#8, #12, #18). The hybrids acquired the metastasis tropisms from both parental cells. Expression profiles of the parental cells, the hybrids and several previously characterized MDA-MB-231 metastatic derivatives were compared. Hierarchical clustering showed the hybrids assimilated the organ-specific metastasis gene signatures from both parental cells. Experiment Overall Design: Twenty-six cell lines were analyzed, including the parental line MDA-MB-231; cell fusion partner lines Bm and Lm; self-fused lines BBm and LLm; hetero-fused lines BLm-FACS, BLM-DRUG and clones BLm-DRUG-8, -12 and -18; strongly bone-metastatic lines 1833, SCP14, SCP20, SCP25 and SCP46; strongly lung-metastatic lines 3481, 4142, 4173, 4175 and 4180; and weakly metastatic lines SCP3, SCP4, SCP6, SCP28, SCP32 and SCP43. Single sample for each line.
