Project description:To examine the effects of recombinant granulin on human mammary stromal fibroblasts, we cultured normal human mammary fibroblasts in the presence of recombinant human granulin (1ug/ml) or PBS every 24h for 6 days. We cultured normal human mammary fibroblasts in the presence human granulin (1ug/ml) or PBS control every 24h for 6 days. The analysis showen are for 3 control (control) and 3 granulin-treated (PGRN) fibrobast cultures.

Project description:To examine the effects of recombinant granulin on human mammary stromal fibroblasts, we cultured immortalized GFP+ normal human mammary fibroblasts in the presence of recombinant human granulin (1ug/ml) or PBS every 24h for 6 days. To generate GRN-independent CAFs, we injected immortalized GFP+ human mammary fibroblasts, MCF7Ras human breast carcinoma cells, and 20% Matrigel subcutaneously into nude mice. Tumors were allowed to form for a period of 45 days. GFP+ fibroblasts were isolated from tumors by mincing the tumors, dissociating, and culturing in the presence of 1 ug/ml puromycin for ~3-4 weeks. CAF purity was confirmed by ensuring that 100% of the population was GFP-positive.

Project description:Columnar cell hyperplasia (CCH) is the first histologically identifiable lesion in the breast with premalignant potential. Altered miRNA expression in the stroma surrounding CCH compared to normal tissue was discovered. The effect of upregulation of one specific miRNA was investigated by gene expression array in human mammary fibroblasts as well as in epithelial CCH cells coculterd with miR-132 oversexpressing human mammary fibroblasts. We used microarrays to detail the effects of miR-132 in human mammary fibroblasts and identified multiple altered genes and gene pathways both in the fibroblasts and in cocultured human mammary epithelial CCH cells.

Project description:Breast cancer is still the most common type of cancer in women; an important role in carcinogenesis is actually attributed to cancer-associated fibroblasts. In this study we investigated whether it is possible to assess the functional state of cancer-associated fibroblasts through tumor tissue proteome profiling. Tissue proteomics was performed on tumor-central, tumor-near and tumor-distant biopsy sections from breast adenocarcinoma patients, which allowed us to identify 2074 proteins. Data were interpreted referring to reference proteome profiles generated from primary human mammary fibroblasts comprising 4095 proteins. These cells were analyzed in quiescent cell state, as well as after in vitro treatment with TGFβ or IL-1β, stimulating wound healing or inflammatory processes, respectively. Representative for cancer cells, we investigated the mammary carcinoma cell line ZR-75-1, identifying 5212 proteins. Comparison of tissue proteomics data with all those reference profiles revealed predominance of cancer cell-derived proteins within the tumor and fibroblast-derived proteins in the tumor-distant tissue sections. Remarkably, proteins characteristic for acute inflammation were hardly identified in the tissue samples. In contrast, several proteins found by us to be induced by TGFβ in mammary fibroblasts, including fibulin-5, SLC2A1 and MUC18, were positively identified in all tissue samples, with relatively higher abundance in tumor neighboring tissue sections. These findings indicate a predominance of cancer-associated fibroblasts with wound healing activities localized around tumors.

Project description:The mouse mammary gland undergoes severe morphological changes during each pregnancy cycle. These are controlled by epithelial as well as stromal factors, including fibroblasts. This project aimed to identify factors that are expressed in mammary fibroblasts during early pregnancy (day3) when the first morphological changes become microscopically visible.

Project description:The secretome of cancer and stromal cells generates a microenvironment which contributes to tumour cell invasion and angiogenesis. Here, we compare the secretome of human mammary normal fibroblasts and cancer-associated fibroblasts (CAF). We discover that the chloride intracellular channel protein 3 (CLIC3) is an abundant component of the CAF secretome. Secreted CLIC3 promotes invasive behaviour of endothelial cells to drive angiogenesis and increases invasiveness of cancer cells both in vivo and in 3D cell culture models, and this requires active transglutaminse-2 (TGM2). CLIC3 acts as a glutathione-dependent oxidoreductase which reduces TGM2 and regulate TGM2 binding to its cofactors. Finally, CLIC3 is secreted also by cancer cells, is abundant in the stromal and tumour compartments of aggressive ovarian cancers, and its levels correlate with poor clinical outcome. This work reveals an unprecedented invasive mechanism whereby the secretion of a glutathione-dependent oxidoreductase drives angiogenesis and cancer progression by promoting TGM2-dependent invasion.
