(Submitter supplied) To characterize the effects of IGF 1 on primary breast fibroblasts, we cultured pre-starved primary breast fibroblasts (normal and carcinoma associated) from three patients 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. 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) Substantial evidence implicates IGF-I signaling in the development and progression of breast cancer. To identify transcriptional targets of IGF action in breast cancer cells, we performed gene expression profiling (>22,000 RNA transcripts) of IGF-I-stimulated MCF-7 cells, a well characterized breast cancer cell line that is highly responsive to IGFs. We defined an IGF-I gene signature pattern of hundreds of genes either up-regulated or down-regulated at both 3 and 24 hrs in vitro. more...

Analysis of breast cancer MCF-7 cells stimulated with insulin-like growth factor-I (IGF-I) for 3 or 24 hours. High serum IGF-I levels are associated with an elevated risk of breast cancer. Results provide insight into the role of IGF-1 in the development and progression of breast cancer.

(Submitter supplied) Hypoxia triggers aggressive cancer growth and contributes to chemotherapy resistance. Novel therapeutic strategies aim at targeting hypoxia activated signaling pathways. Tumor hypoxia not only affects neoplastic tumor cells but also the surrounding stroma cells. Therefore, a novel ex vivo model was established, which allows the study of hypoxia effects in fragments of non-small cell lung cancer (NSCLC) with preserved tumor microenvironment and 3D-structure. more...

(Submitter supplied) Purpose: Multiple studies from last decades have shown that the microenvironment of carcinomas plays an important role in the initiation, progression and metastasis of cancer. Our group has previously identified novel cancer stroma gene expression signatures associated with outcome differences in breast cancer by gene expression profiling of two tumors of fibroblasts as surrogates for physiologic stromal expression patterns. more...

(Submitter supplied) Primary tumor growth induces host tissue responses that are believed to support and promote tumor progression. Identification of the molecular characteristics of the tumor microenvironment and elucidation of its crosstalk with tumor cells may therefore be crucial for improving our understanding of the processes implicated in cancer progression, identifying potential therapeutic targets, and uncovering stromal gene expression signatures that may predict clinical outcome. more...

Analysis of stroma associated with prostate and breast invasive tumors. Stromal reaction (tumor-associated tissue remodeling) occurs in various cancers. Results provide insight into whether this stromal response is largely a generic phenomenon or whether it reflects tumor-specific properties.

(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

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...

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) Obesity is thought to contribute to worse disease outcome in breast cancer as a result of increased levels of adipocyte-secreted endocrine factors, insulin, and insulin-like growth factors (IGFs) that accelerate tumor cell proliferation and impair treatment response. We examined the effects of patient obesity on primary breast tumor gene expression, by profiling transcription of a set of tumors for which the patients’ body mass index (BMI) was ascertained. more...

(Submitter supplied) The mechanisms involved in epithelium-stroma interactions remain poorly understood, despite the importance of the microenvironment during tumorigenesis. Here, we studied the role of Ets2 transcrpiton factor in tumor associated fibroblasts in the MMTV-ErbB2 mammary tumor model. Inactivation of Ets2 specifically in fibroblasts using Fsp-cre significantly reduced tumor growth, in contrast to Ets2 inactivation in epithelium in which no differences in tumor growth were observed. more...

(Submitter supplied) Tumor associated fibroblasts are known to play an important role in angiogenesis, however the specific signaling pathways playing an important role in this cross talk remain ill defined. Here, we studied how Ets2 transcrpiton factor signaling in tumor associated fibroblasts effected gene expression in surrounding endothelial cells in the MMTV-PyMT mammary tumor model. Inactivation of Ets2 specifically in fibroblasts using Fsp-cre significantly reduced tumor associated angiogenesis, and was indicated to effect ECM remodeling, cell adhesion and cell chemotaxis processes in neighboring endothelial cells. more...

(Submitter supplied) The ability to predict metastatic potential is of clinical and biological importance. Numerous metastasis/relapse predictors exist for breast cancer patients; however, what is less well established is whether predicting metastasis to specific organs sites is feasible. In this study we sought to determine: 1) the degree to which gene signatures vary across tumors and their metastases, 2) if genomic intrinsic subtypes associate with particular organs of relapse, and 3) if other genomic signatures can predict spread to specific organs. more...
