Gene expression profiling in MCF-7 cells exposed to blackcurrant extract.

ABSTRACT: Blackcurrants (Ribes nigrum L., Grossulariaceae) have a high content of anthocyanin polyphenols and these have been shown to have beneficial effects on health, owing to their antioxidant and anti-carcinogenic properties. This study analyzed the constituents of blackcurrant extract (BCE) and investigated its potential phytoestrogenic effects using a breast cancer cell line (MCF-7) overexpressing the estrogen receptor (ER) Î±. Microarray and ingenuity pathway analysis showed that BCE activated upstream genes such as ERÎ± and transforming growth factor beta 1, and upregulated the expression of many genes downstream of ERÎ±. MCF-7 cells were seeded in culture dish and maintain to confluent. Then medium replace with phenol-red-serum-free DMEM medium with or without BCE (50Î¼g/ml). After the cells were incubated for 24 h at 37 Â°C 5% CO2.

Gene expression signatures in uteri from nuclear and membrane effects of Estradiol on Estrogen receptor ERÎ±

Project description:To further study gene expression regulated by 17b-estradiol in uteri, we have employed whole gene microarray profiling to identify genes specifically regulated by the Estrogen receptor ERÎ± localized either at the plasma membrane or in the nucleus. Two mice models have been used, the mice named ERa-AF2Â° (named AF2_KO and on C57BL6/J background) in which 7 aminoacids have been deleted in the AF2 domain and the mice C451A-ERa (named MISS_KO and on C57BL6/N background) mutated for the C451 into Ala on ERa. Control littermates were used for each mutant mice respectively name AF2_WT or MISS_WT. 17b-estradiol induced gene expression in uteri from ovariectomized mice was measured after 6 hours exposure to 0 (PLB) and 8Âµg/kg of 17b-estradiol (E2) injected subcutaneously in castor oil.

Effect of cajanin stilbene acid and its synthetic derivatives on MCF-7 breast cancer cells

Project description:Cajanin stilbene acid (CSA) was previously shown to induce cytotoxicity against cancer cells. We have employed microarray gene expression profiling to identify deregulated genes in MCF-7 breast cancer cells upon treatment with CSA and its synthetic derivatives (CSA6, CSA9, CSA19). TGM2 gene encoding transglutaminase 2 was commonly deregulated after treatment with all four CSA compounds. All compounds revealed strong effects on cell cycle progression and DNA damage response. Promoter motif analysis of the deregulated genes further supported the microarray results emphasizing the relevance of transcription factors regulating cell cycle and proliferation, MYC being among the most pronounced ones. Interestingly, cellular movement was among the top five affected cellular functions after treatment with the four derivatives. Gene expression profiling study with Whole Human Genome RNA chips (8M-CM-^W60K Agilent) was performed in MCF-7 breast cancer cells upon treatment with CSA and its synthetic derivatives (CSA6, CSA9, CSA19). Twelve chips were used; control (x2), CSA (x2), control (x2), CSA6 (x2), CSA9 (x2), CSA19 (x2). MCF-7 cells were treated with the compounds (IC50 concentrations) for 72 hours or left untreated (DMSO control). Two independent experiments were performed for each treatment.

The gene expression change of RNF31 depletion in MCF-7 cells

Project description:RNF31 is atypical E3 ligase, which is highly expressed in human breast cancers. In order to understand the effect of RNF31 depletion effect in breast cancers, we knocked down the expression of RNF31 in MCF-7 cells. We aim to find the significantly changed pathways and cell biology behavior. 100uM RNF31 siRNA was applied to transfect the MCF-7 cells, while 100uM siControl was used as the control. Cells were cultured in DMEM red medium with 10% of FBS. Seventy two hours of post transfection, the total RNA was extracted to perform RNA expression analysis.

RNA-seq of the human breast cancer ERÎ±-suppressed MCF-7(MCF-7/SP10+) cells and of their internal control MCF-7 (MCF-7/C) cells

Project description:Estrogens receptor a (ERÎ±) is essential for breast tumors,since about seventy percent of breast cancers are detected as ERÎ± positive.Recent studies suggest that ERÎ± is related with the epithelial cell morphology. Recently, it has demonstrated that the suppression of ERÎ± induced epithelial-mesenchymal transition (EMT) in the MCF-7 breast cacner cells. Interestingly, the loss of ERa resulted in strong differences on the gene expression profile of a variety of genes. Therefore, the aim of the RNA-seq is to elucidate the effect of the silencing of ERÎ± on the mRNA levels of a larger variety of genes, thus revealing possible target genes which may be implicated on the aggressive phenotype and behavior of the ERÎ±-suppresed MCF-7/SP10+ breast cancer cells. For this reason total RNA from both MCF-7/SP10+ cells and of their internal control MCF-7/C cells was extracted in 3 biological replicates and 3 technical replicates.

Generation of neural progenitor cells by chemical cocktails and hypoxia

Project description:Neural progenitor cells (NPCs) can be induced from somatic cells by defined factors. Here we report that NPCs can be generated from mouse embryonic fibroblasts by a chemical cocktail, namely VCR (V, VPA, an inhibitor of HDACs; C, CHIR99021, an inhibitor of GSK-3 kinases and R, Repsox, an inhibitor of TGF-β pathways), under a physiological hypoxic condition. These chemical-induced NPCs (ciNPCs) resemble mouse brain-derived NPCs regarding their proliferative and self-renewing abilities, gene expression profiles, and multipotency for different neuroectodermal lineages in vitro and in vivo. Further experiments reveal that alternative cocktails with inhibitors of histone deacetylation, glycogen synthase kinase, and TGF-β pathways show similar efficacies for ciNPC induction. Moreover, ciNPCs can also be induced from mouse tail-tip fibroblasts and human urinary cells with the same chemical cocktail VCR. Thus our study demonstrates that lineage-specific conversion of somatic cells to NPCs could be achieved by chemical cocktails without introducing exogenous factors. To access the exact identity of ciNPCs, we extracted mRNA from mouse brain-derived NPCs (as control NPCs), MEFs, ciNPCs at passage 5 and passage 13 and compared the global gene expression patterns of these cells by microarray analysis.
