A microRNA regulon that mediates endothelial recruitment and metastasis by cancer cells.

Png Kim J KJ Halberg Nils N Yoshida Mitsukuni M Tavazoie Sohail F SF

Nature 20111214 7380

Metastatic progression of cancer is a complex and clinically daunting process. We previously identified a set of human microRNAs (miRNAs) that robustly suppress breast cancer metastasis to lung and bone and which display expression levels that predict human metastasis. Although these findings revealed miRNAs as suppressors of cell-autonomous metastatic phenotypes, the roles of non-coding RNAs in non-cell-autonomous cancer progression processes remain unknown. Here we reveal that endogenous miR-1 ...[more]

Tumorigenic-enriched (TE) and lung-metastatic (LM) derivatives and parental populations from the breast cancer MDA-MB-231 and CN34 cell lines

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.

Human breast cancer LM2 cell lines: control vs. MTDH knockdown

Project description:Transcriptional profiling of human breast cancer cell line LM2, a subline of MDA-MB-231 highly metastatic to lung when injected to nude mice, to identify the genes that are regulated after the metastasis gene metadherin is knocked down. Keywords: Genetic modification Empty pSuper vector control cells were compared to the cells transfected with the MTDH knockdown shRNA construct. Two cultured conditions were studied: the LM2 cancer cells were cultured alone or on top of a monolayer of human lung endothelial HMVEC-L cells. Three arrays for each sample.
