Project description:RNAseq transcriptomic analysis of MCF10A-CT, MC26 and M1B26 cell lines. MCF10A cells are human not transformed mammary stem-like cells that do not form colonies in soft-agar assay and do not engraft in immunocompromised mice. MC26 are MCF10A derivatives that were submitted to long-term culture in presence of human recombinant BMP2 and IL6 for several weeks until colony formation in soft-agar was detected. M1B26 are MCF10A derivatives that were sorted for high expression of the BMPR1b BMP receptor prior to BMP2 and IL6 treatment and expanded from several soft-agar colonies. M1B26 are more transformed than MC26 based on the frequency of soft-agar colonies forming cells and on the ability to engraft in mice. As a control, MCF10A-CT were kept in culture for similar length of time than MC26 and M1B26 but without BMP2 and IL6 and do not generate soft-agar colonies or engraft in mice. This study aims to document the transcriptomic changes associated with early transformation events mediated by abnormal exposure to BMP2 and inflammatory signal.
Project description:Overexpression in IL6 in MCF10A vs. WT, MCF10A.ErbB2* with/without shRNA targeting STAT3 Overexpression in IL6 in MCF10A vs. WT, MCF10A.ErbB* with/without shSTAT3, duplicates, two STAT3 shRNAs
Project description:To investegate how IL6 regulates human monocyte transcriptional profiles, we stimulated primary human monocytes in vitro with IL6 and IL6R.
