Project description:Transcriptional profiling of human MCF-7 breast cancer cells comparing MCF-7 cells treated with control medium (DMEM/F12 + 0,5% BSA) with MCF-7 cells treated with conditioned medium of cancer-associated adipose tissue (CMCAAT) obtained from 2 breast cancer patients. Goal was to determine the effects of CMCAAT treatment on global MCF-7 gene expression.

Project description:Paracrine signals relayed between heterogenous cell types through small and large extracellular vesicles promote cancer cell growth, invasion and metastasis. Microplasts, also called as cytoplasts or cytokineplasts are large extracellular vesicles (0.5-11µm diameter) originating from migratory cells. Microplasts are known to be associated with invasive phenotypes of cancer cells and promote metastasis. Treatment with macrophage conditioned medium induces significant shedding of microplasts from MCF-7 breast adenocarcinoma cells. To characterise microplasts and to study their potential role in intercellular communication in cancer, we isolated microplasts derived from macrophage conditioned medium treated MCF-7 cells and investigated their protein cargo through LC-MSMS.

Project description:To investigate whether conditioned medium (CM) from cancer cell culture impacts dynamic changes of the transcriptome in myotubes differentiated from hMuSC, we ran RNA sequencing from differentiated hMuSC that were treated by multiple breast cancer cell lines-conditioned medium. Among 14208 readable mRNAs, MCF-7 CM treatment induced significant changes in 2680 genes, MB-468 CM caused significant changes in 2674 genes, and SKBR-3 CM resulted in significant changes in 1823 genes in myotubes from differentiated hMuSC, compared to control group, respectively. Among them, 961 genes had significant upregulation or downregulation presented in differentiated myotubes over all 3 breast cancer cell lines CMs

Project description:We treated nine lines of breast cancer cells with conditioned medium derived from NAF and CAF to study the paracrine interaction beetween stroma and tumor. Gene expression profiles for breast cancer cell lines are reported after 72h of treatment with conditioned medium derived from NAF and CAF or with control media.

Project description:Here, we report a transcriptomics analysis on MCF-7 breast cancer cells exposed to adipocyte conditioned medium (CM) and focus on the functional relevance that CM-affected pathways and processes and related biomarkers may have in breast cancer response to obesity.

Project description:The subpopulations of mesenchymal stem cells isolated from breast adipose tissue which display migrated towards conditioned media from MDA-MB231 cell line were expanded for miRNA analysis. The tumor microenvironment (TM) is known to promote tumor growth and progression. Ubiquitously distributed tissue resident stem cells (MSCs) elicit regenerative properties. In addition, they are capable of homing to sites of inflammation, injury, and tumor. Considering the tumor tropic property of MSCs, the interaction between the breast cancer (BC) microenvironment and breast resident adipose tissue derived MSCs (ASCs) merits further investigations. Initial data indicate that a subset of ASCs derived from breast adipose tissue (B-ASCs) display a high affinity towards the conditioned media (CM) from two breast cancer cell lines, MDA-MB231 (MDA-CM) and MCF7 (MCF-CM). Profiling secreted cytokines of these CMs identified significant expression of angiogenin, GM-CSF, and IL-6. While the expression of GRO-M-NM-1, MCP-1, RANTES, and IL-1M-NM-1 is more pronounced in MDA-CM, MCF-CM contains higher amounts of IGFBP2, TRAIL, and ErbB3. Gene expression profiling suggests that despite the distinct differences, both migratory subset of B-ASCs towards MDA-CM and MCF-CM display perturbed expression of genes like KISS1, TNSF1, IL18 and MMP2, which could be associated with a defensive role of B-ASCs. In addition, the BC microenvironment alters microRNA (miRNA) expressions in B-ASCs. in this study the migratory cells were evaluated for miRNA expression versus non-migratory counterparts. as controls unexposed parental cell lines (2) were used on the same hybridization chip in which one labeled Hy3 and other labeled Hy5. The ratio of the control parental cells was used as base nanalysis of miRNA expression in MSCs. we also include another control in this study, the migratory subpopulations of MSCs which display migratory potentials against protein gradient (M5) were analyzed for miRNA expression versus non-migratory counterparts (NM-5). using this control facilitate identification of those miRNA responsive to tumor CM. the data analysis confirm that altered gene and miRNA profiles resulted from exposure of MCF-CM and MDA-CM on B-ASCs are similar to those observed in B-ASCs isolated from breast adipose tissue of BC patients. Analysis the signaling between the B-ASCs and TM may help in understanding the possible role of B-ASCs in stasis, progression, or regression of the BC. The microRNA expression of migratory subpopulations were compared to parental populations of MSCs.

Project description:The disturbance of adipose tissue in obesity highly correlates with cancer progression. To investigate the impacts of obesity on triple-negative breast cancer (TNBC), we performed an in vitro system culturing TNBC cells with human white adipocytes-conditioned medium (hAd-CM). The gene expression profiling between each condition was then assessed by RNA-seq.

Project description:A major development in the study of obesity is the recognition that the condition is characterised by chronic mild inflammation. Within adipose tissue, this involves the infiltration of macrophages, as well as the direct inflammatory response of the adipocytes and pre-adipocytes. This study has used Agilent whole-genome microarrays to examine the effects of macrophage-conditioned medium on the global inflammatory response of human pre-adipocytes. Human pre-adipocytes (SGBS cells) were treated with macrophage (U937 cells) conditioned medium for 24 h. Control pre-adipocytes were treated with unconditioned medium (control) or RPMI-1640 media alone to control for differences in media used to culture the U937 cells. There were 5 biological replicates per group.
