(Submitter supplied) These 95 arrays are the basis for Figure 2 of our manuscript "An interferon-response induced by tumor-stroma interaction in a subset of human breast cancers". Abstract:Background Communication between different cell types is a cardinal feature of multi-cellular organisms and perturbations in these cell-cell interactions are a key feature of cancer. However, little is known about the systematic effects of cell-cell interaction on global gene expression in cancer. more...

(Submitter supplied) These 12 arrays are the basis for Figure 1 of the "An interferon-response induced by tumor-stroma interaction in a subset of human breast cancers" manuscript. Figure 1: Effect of heterotypic interaction between breast cancer cell line MDA-MB231 and CCL-171 fibroblast. Biologically independent replicates of the mono-cultured fibroblast CCL-171, the breast cancer cell line MDA-MB231 and the mixed co-culture of CCL-171 and MDA-MB231 were grown for 48h at low serum conditions and characterized by DNA microarray hybridization. more...

(Submitter supplied) Bone is the most common site of breast cancer metastasis, and this type of metastasis is a main cause of morbidity. Because breast cancer is a heterogeneous disease, the interactions between the cancer cells and the skeletal host cells, such as osteoblasts, might be diverse. Thus far, these tumor-osteoblast interactions have not yet been well characterized using a genomic approach. We hypothesized that gene expression signatures induced by tumor-osteoblast interactions might be of clinical relevance. more...

(Submitter supplied) As a model for investigating changes in gene expression in response to epithelial-osteoblast interactions in bone metastases of breast carcinomas, cells that represented malignant epithelial cell compartments (T47D) and cells that represented skeletal compartments (Normal Human (NH) Osteoblasts) were examined in an in vitro mixed co-culture setting. These two types of cells were co-cultivated for 48 h in a low-serum medium [0.2% fetal bovine serum (FBS)] to allow reciprocal signal exchange with minimal background from undefined molecular signals that are inherent in fetal bovine serum. more...

(Submitter supplied) To characterize the effects of IGF 1 on CCL171 cells, we cultured pre-starved CCL 171 fibroblasts with or without 50ng/ml IGF 1 for 24 h. We then profiled gene expression changes using Human Exonic Evidence Based Oligonucleotide (HEEBO) microarrays. After stimulation, total RNA was extracted and amplified using a modified Eberwine procedure. The amplified RNA was labeled with the fluorescent dye Cy5 and pooled with Cy3 labeled reference RNA, and then the pooled RNA was hybridized onto HEEBO microarrays. more...

(Submitter supplied) Basal-like breast cancers have several well-characterized distinguishing molecular features, but most of these are features of the cancer cells themselves. The unique stromal-epithelial interactions, and more generally, microenvironmental features of basal-like breast cancers, have not been well characterized. To identify characteristic microenvironment features of basal-like breast cancer, we performed cocultures of several basal-like breast cancer cell lines with fibroblasts (reduction mammoplasty-derived fibroblast line; RMF) and compared these to cocultures of luminal breast cancer cell lines with fibroblasts. more...

(Submitter supplied) We established co-cultures of invasive or non-invasive NSCLC cell lines and various types of fibroblasts (FBs) to more precisely characterize the molecular mechanism of tumor-stroma crosstalk in lung cancer Differential expression analysis of the respective mono- and co-cultures revealed an upregulation of NFκB-related genes exclusively in co-cultures with Calu-1. Cytokine Array- and ELISA-based characterization of the “cytokine fingerprints” identified CSF2 (GM-CSF), CXCL1, CXCL6, VEGF, IL6, RANTES and IL8 as being specifically upregulated in various co-cultures

(Submitter supplied) Cancer-associated fibroblasts (CAFs) existing in tumor stroma play a crucial role in tumor progression. Here, we show that stromal fibroblasts near cancer cells are likely to display up-regulated RHBDF2 expression caused by chronic stimulation from pro-inflammatory cytokines. RHBDF2 promotes both the cleavage of type I transforming growth factor (TGF)-b receptor, through tumor necrosis factor α converting enzyme activation, and the motility of CAFs upon stimulation with TGF-b1. more...
