Description
E-cadherin (E-cad) mediates cell-cell adhesion and has been proposed to suppress both invasion and metastasis. However, invasive ductal cancers retain E-cad expression in the primary tumor, circulating tumor cells, and distant metastases. We recently demonstrated that cancer cell clusters are efficient metastatic seeds. Since clusters organize through cell-cell adhesion, we tested the requirement for E-cad in genetically engineered mouse models of luminal and basal breast cancer. Loss of E-cad increased invasion and dissemination in 3D culture and in the mammary gland. However, E-cad loss also reduced cancer cell proliferation, survival, tumor cell seeding, and metastatic outgrowth in the lungs. At the transcript level, loss of E-cad was associated with increased apoptosis. Consistent with these results, inhibition of apoptosis partially rescued the metastatic phenotype of E-cad null cancer cells. We therefore propose that E-cad is an invasion suppressor, survival factor, and metastasis promoter in invasive ductal cancers. Overall design: Differential gene expression analysis between organoids isolated from adeno-Cre transduced MMTV-PyMT E-cad+/+ (r = 4 biological replicates) and adeno-Cre transduced MMTV-PyMT E-cadfl/fl (r = 5 biological replicates)

Description
The tyrosine kinase receptors HER2 and HER3 play an important role in breast cancer. The HER2/HER3 heterodimer is a critical oncogenic unit associated with reduced relapse-free and decreased overall survival. We provide gene expression profile of the mammary epithelial cells MCF10A expressing HER2, HER3 or HER2/HER3 and grown in three-dimensional cultures for 15 days in the presence of heregulin, a known HER3-ligand that stabilizes and activates the HER2/HER3 heterodimer.

Description
The Epidermal Growth Factor Receptor 2 (ERBB2 or HER2) is amplified and overexpressed in approximately 20% of invasive breast cancers and is associated with metastasis and poor prognosis. Here we describe the role of a constitutively active splice variant of HER2 (Delta-HER2) in human mammary epithelial cells. Overexpression of Delta-HER2 in human mammary cells decreased apoptosis and increased proliferation and expression of epithelial-to-mesenchymal markers. It also induced invasion in three-dimensional cultures and promoted tumorigenicity and metastasis in vivo. In contrast, similar overexpression of wild-type HER2 failed to evoke the same effects. Unbiased protein-tyrosine phosphorylation profiling revealed a significant increase in phosphorylation of several key signaling proteins upon Delta-HER2 expression, some of which not previously shown to belong to the HER2 pathway. In addition, microarray analysis revealed the expression of a set of genes specifically associated with Delta-HER2 expression. We found those genes to be highly expressed in ER-negative, high grade and metastatic primary breast tumors. Altogether, these results provide new insights into the function of a tumorigenic splice variant of HER2 and the signaling cascade deriving from its activity

Description
Obesity has emerged as a formidable health crisis due to its association with metabolic risk factors such as diabetes, dyslipidaemia and hypertension. Recent work has demonstrated the multifaceted roles of lncRNAs in regulating mouse adipose development, but its implication in human adipocytes remain largely unknown at least partially due to the lack of a comprehensive lncRNA catalog, particularly those specifically expressed in brown adipose tissue (BAT). In this study, we performed deep RNA-seq on adult subcutaneous, omental and fetal brown adipose tissues to de novo construct a catalog of 3,149 adipose active lncRNAs of which 1,351 are specifically detected in BAT. We further identified 318 lncRNAs conserved between human and mouse which, compared with non-conserved ones, are more broadly expressed in multiple cell types. One of these, lnc-dPRDM16, is transcribed divergently from Prdm16, tightly correlated with Prdm16 (R = 0.7) in both mouse and human, and co-expressed (R = 0.7) with protein-coding genes enriched in lipid and fatty acid catabolic processes. Loss of function of lnc-dPRDM16 led to a down-regulation of Prdm16 and an obvious reduction of adipogenesis in brown adipocyte culture. Together, our work has provided a comprehensive human adipose catalog built from diverse fat types, which when applied to our roadmap, identifies lnc-dPRDM16 as a promising modulator of adipose development for future clinical research. Overall design: Transcriptome profiling of BAT, OME and SUB samples
