Description
Elf5 expression in mammary progenitor cells regulates a cell fate decision that establishes the alveolar cell lineage. In luminal breast cancer cells, increased Elf5 expression suppressed estrogen receptor and FoxA1 expression and was implicated in the acquisition of resistance to the cytostatic effects of antiestrogen therapy. We show that in the PyMT model of luminal breast cancer, increased Elf5 expression drives lung metastasis by recruiting myeloid-derived suppressor cells, and that this activity overcomes the epithelializing influence of Elf5. Breast cancer expression signatures identify a similar process in humans, and increased Elf5 immunohistochemical staining predicts poor prognosis in the luminal A subgroup. Thus Elf5 may promote escape from hormonal therapy and drive metastasis in luminal breast cancer.

Description
Microarray analysis of mRNARNA was prepared from ESCs (CGR8 and CJ7), MEFs, and iPSCs with a PureLink RNA Mini Kit (Life Technologies). Initial sample quality control was performed with a Nanodrop 8000 (Thermo Scientific). RNA samples with an optical density (OD) 260/280 ratio and an OD 260/230 ratio of 1.8 or higher were used. Samples with an RNA Integrity Number of 7.5 or greater measured with a LabChip Caliper GX (Perkin Elmer) were applied to an Illumina TotalPrep-96 RNA Amplification Kit (Life Technologies) to generate biotinylated and amplified RNA. With this kit, 300 ng of total RNA was first processed in a reverse transcription reaction. The cDNA then underwent second-strand synthesis and cleanup to serve as a template for in vitro transcription, which generated biotinylated antisense RNA copies of each mRNA. Samples went through another round of quality control with the Nanodrop 8000 and were applied to Illumina MouseWG-6 v2.0 Beadchips (#BD-201-0202). After overnight hybridization, the Beadchips were washed, stained, and scanned using an Illumina iScan Beadarray Reader. The obtained data were analyzed with an Illumina Genome Studio.

Description
Branching morphogenesis in lung development is regulate by growth factor signaling. Wnt signaling is one of the important singnaling pathway that is required for progenitor maintainance. In the presence of CHIR99021, an agonist for the beta-catenin pathway of Wnt signaling, specific group of genes are upregulated in cultured lung epithelium.

Description
"Omics" technologies have been developed to understand the whole complex microbial systems; however, most omics studies reported so far were utilized to analyze the living matters of single-species. To understand the cell-cell interaction in the gut microbial complex, we selected to examine the interaction of Escherichia coli O157:H7 (O157) and Bifidobacterium longum (BL), known as a pathogenic and a commensal bacteria, as a first step for understanding the whole gut microbial complex. We have developed a novel time-lapse 2D-NMR metabolic profiling system in order to measure the extracellular metabolites, which are considered a key factor to understand the bacterial crosstalk. Furthermore, in combination with transcriptome and proteome analysis, we found that the relationship between BL and O157 could be partially regarded as the producer and the consumer of nutrients, especially in the case of serine and aspartate metabolism. These findings suggest that our novel profiling systems could be a powerful tool toward understanding crosstalk of the whole microbial complex such as the gut, industrial bioreactors or environmental microbial communities.
