Project description:Comprehensive analysis of coding and non -coding transcriptome using ribo-depleted total RNA-seq and poly A selected RNA-seq of MCF-7 cells grown in hypoxia and normoxia. Breast cancer cell line (MCF-7) is cultured in normoxic condition (21% O2) and hypoxic condition (1%O2) for 24 hours. Expression of HIF-1alpha and/or HIF-2alpha subunits was suppressed using siRNAs in hypoxic MCF-7 cells. Total RNA was isolated from both hypoxia and normoxia conditions were subjected for ribosomal depleted stand specific RNA-seq and poly A selected RNA-seq

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:Annexin 1 (ANXA1), an endogenous anti-inflammatory protein which modulates cellular processes such as proliferation, differentiation and apoptosis has been implicated in cancer initiation and progression. ANXA1 was previously shown to be regulated by hsa-miR-196a and promoted cell proliferation and anchorarge-dependent growth and suppressed apoptosis. However, whether ANXA1 itself regulates miRNA expression is unknown. Therefore, in this study, we investigated the regulation of miRNA by ANXA1 in breast cancer cells. Using microarray technology, 12 miRNAs were found to be significantly and consistently downregulated in MCF-7 cells (MCF-V5) overexpressing ANXA1 overexpressing MCF-7 cells (MCF-V5). Hsa-miR-26b* and hsa-miR-562 were chosen for further investigation.The data suggest that miR-26b* and miR-562 may play a role in ANXA1-induced migration and possibly angiogenesis by targeting NFKB and point towards a potential therapeutic target for breast cancer. Breast cancer MCF-7 cells (MCF-V5) overexpressing ANXA1 were cultured for RNA extraction and hybridization on Affymetrix miRNA microarrays. These were compared against the control, which were MCF-7 cells (MCF-EV) carrying an empty expression vector. Expression analyses were carried out in triplicates

Project description:To clarify transcriptional target genes of GLI1 in human mammary epithelial cells and breast cancer cells, primary culture cells of human mammary epithelium HMEC and breast cancer cell line MCF-7 were lentivirally transduced by either GLI1 or its control LacZ. Their RNA samples were served for expression analysis using AGILENT human 8x60K cDNA microarray.

Project description:Identifying PDEF regulated genes may shed light on the mechanism by which PDEF may induce breast cancer progression. To that purpose, we have used the MCF-7 human breast tumor cell line model to identify PDEF induced genes. Briefly, PDEF expression was down regulated by shRNA in MCF-7 cells and RNA probes from PDEF-down regulated and control MCF-7 cells were used to screen the Affymetrics HG-U133A Gene Chips. This analysis found 62 genes that were induced 2-fold or higher by PDEF. Further analysis of 3 of these genes namely S100A7, CEACAM6 and B7-H4 in primary breast tumors showed CEACAM6 as a frequently elevated and co-exressed gene with PDEF in these tumors. We previously reported a role for PDEF (prostate derived Ets transcription factor) in breast tumor progression and its association with poor clinical outcome in ER+ breast cancer. To gain further insights into PDEF action in breast cancer, we down regulated PDEF expression by shRNA in MCF-7 human breast tumor cell line, and screened the HG-U133A human gene chips with probes from PDEF down-regulated and control MCF-7 cells. This analysis identified CEACAM6 as one of the genes induced by PDEF. Further analysis of CEACAM6 expression in relation to PDEF in 93 ER+ primary breast tumors showed largely concordant expression of these molecules. To our knowledge, our findings of CEACAM6 as a PDEF induced gene and their elevated co-expression in breast cancer have not been described before. Data from one replicate experiment is included as a representative example of the data obtained. HG-U133A gene chip pairs were screeened with biotinylated RNA probes from PDEF-down regulated MCF-7 cells (experimental) or from control MCF-7 cells.
