Project description:The current study analyzed the altered expression profiles of genes that are responsible for fluvastatin-induced breast cancer cell death in MCF-7 cells (ER+ve luminal breast cancer cells). Some of these altered gene expressions were further inter connceted to various pathways which may eventually be recognised as drug targets/ biomarkers in statin-sensitve breast cancer patients. To understand the differential gene expression profile in fluvastatin treated (24 h) malignant breast cancer cells with untreated malignant breast cancer cells.
Project description:The current study analyzed the altered expression profiles of genes that are responsible for fluvastatin-induced breast cancer cell death in MDA-MB-231 cells (ER-ve basal breast cancer cells). Some of these altered gene expressions were further inter connceted to various pathways which may eventually be recognised as drug targets/ biomarkers in statin-sensitve breast cancer patients. To understand the differential gene expression profile in fluvastatin treated (24 h) malignant breast cancer cells with untreated malignant breast cancer cells.

Project description:The current study analyzed the metadherin (MTDH)-mediated altered gene expression profiles in ER positive MCF-7 cells. Some of these altered gene expressions were further inter connected to various pathways which may eventually be recognized as drug targets or biomarkers in those breast cancers where MTDH plays a role in cancer progression/metastasis. To understand the global differential gene expression profile in MTDH-wild type and a newly identified MTDH-isoform knock down in malignant breast cancer cells. This data was compared to untreated breast cancer cells.
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:Microarray analysis of microRNAs differences between MCF-7 and MCF-7/ADR cells.Sample 1- Human breast cancer cell MCF-7,which exibits ER and PR expression, belongs to non-triple negative breast cancer cell with epithelial morphology and character.Sample 2-human breast cancer cell MCF-7/ADR,derived from MCF-7 and cultured with 1 ug/ml adriamycin for at least one year and pocesses adriamycin-resistance with mesenchymal morphology and character. We used microarrays to detail the global programme of microRNA expression between two distinct classes of breast cancer cells.

Project description:Fluvastatin mediated global transcriptional alterations in estrogen positive and negative human breast cancer cells
Project description:To explore the molecular mechanisms and signal pathways induced by restoring tumor suppressor gene HIC-1 on breast cancer cells. We have employed whole genome microarray expression profiling as a discovery platform to identify the differential genes induced by HIC-1 gene activation. Small activating RNA (saRNA) that targeted promoter region was used, and MCF-7 breast cancer cell line was selected as cell model. After 96h for saRNA transfection, the cells were collected and the whole genome expression profiles were analyzed. Three independent experiments were repeated for different groups. With the treshold of p<0.01 and fold change >=2 or <-2, there were 1375 differential expression genes, which are related to cell cycle, apoptosis, cell migration, cell invasion and cell proliferation. SaRNA induced gene expression in human breast cancer cell MCF-7 was measured at 96 hours after transfection by 50 nM saRNA. Three independent experiments were performed for experimental group and control group.
