Transcriptome analysis of gene expression in MCF-7 cell upon circFAT1(e2) depletion

Project description:In previous study, we found circFAT1(e2) was highly expressed in breast cancer tissues and cell lines. And this factor is also a crucial role in breast cancer genesis and development. So in this study, we knocked down circFAT1(e2) in MCF-7 cells. The viability and metastasis was significantly inhibited with circFAT1(e2) depletion. In order to explore the potential down-stream gene of circFAT1(e2) in breast cancer cells. We extracted the total RNA from circFAT1(e2) knockdown MCF-7 cells and negative control group by using TriZol reagent. Then, toal RNA was subjected to transcriptome sequencing to determine the potential down-stream targets of circFAT1(e2). We expect to reveal the underlied mechanism of the regulatory effect on breast cancer of circFAT1(e2).

Expression data for knockdown of H2ac in E2-treated MCF-7 cell lines

Project description:Estrogens(E2) are important steroid hormones that regulate differentiation, proliferation, and apoptosis in hormone-dependent breast cancer.In order to detect the E2-dependent transcription program associated with the observed cell cycle response, we analyzed the effect of H2ac knockdown on MCF-7 gene expression using microarray. Interestingly, we noticed that 51% of the E2-upregulated genes are down-regulated by depletion of H2ac. The data also show that H2ac regulated E2-dependent genes through E2-induction signaling pathway. MCF-7 cell line was transfected with scrambled or H2ac siRNA in the absence or persence of E2.

Global survey of miRNA microarray of MCF-7 cells with or without estrogen (E2) treatment

Project description:To examine the effect of E2 treatment for the miRNA expression in human MCF-7 cells, MCF-7 cells were treated with or without E2 (100 nM) for 4 hr or 24 hr. Four group experiments; E2 (100 nM) treatment for 4 hr (MCF-7 E2 4h_1, MCF-7 E2 4h_2), vehicle (ethanol) treatment for 4 hr as Mock control (MCF-7 Mock1, MCF-7 Mock2), E2 (100 nM) treatment for 24 hr (MCF-7 E2 24h_1, MCF-7 E2 24h_2, MCF-7 E2 24h_3), vehicle treatment for 24 hr as Mock control (MCF-7 Mock_3, MCF-7 Mock_4, MCF-7 Mock_5).

17beta-estradiol (E2)-regulated gene expression across time in estrogen-dependent and estrogen deprivation-resistant MCF-7-derived breast cancer cell lines.

Project description:A series of MCF-7 variants were previously developed that are either estrogen-dependent for growth (MCF-7:WS8 cells), or resistant to estrogen deprivation and refractory (MCF-7:2A) or sensitive (MCF-7:5C) to E2-induced apoptosis. To identify genes associated with E2-induced apoptosis, estrogen deprivation-resistant/apoptotic-sensitive 5C cells were compared to both estrogen-dependent MCF-7:WS8 and estrogen deprivation/apoptotic-refractory MCF-7:2A cells

Effect of estradiol (E2) exposure and KMT2B knockdown on gene expression in MCF-7 cells

Project description:MCF-7 is an estrogen receptor-positive breast cancer cell line. This experiment is designed to study (1) the effect of estradiol (E2) exposure and (2) lysine methyltransferase 2B (KMT2B) knockdown in MCF-7 cells. Cells were grown for 72 hours prior to treatment with vehicle or 10 nM E2 for 4 and 24 hours. Additionally, to assess the effect of KMT2B knockdown, MCF-7 cells were transfected with KMT2B targeting siRNA or scrambled control siRNA in the absence or presence of E2. RNA were isolated using Trizol and hybridized to Affymetrix GeneChip Human Genome U133 Plus 2.0 array.

Effect of JMJD2B depletion on the ER signaling pathway

Project description:JMJD2B is expressed in a high proportion of human breast tumors, and the expression levels significantly correlate with estrogen receptor (ER) positivity. To assess the effect of JMJD2B depletion on the ER signaling pathway, we performed genome-wide gene expression analysis using the Affymetrix Human Gene 1.0 ST array. RNA was extracted from steroid-depleted control MCF-7 cells (control E2(-)), control MCF-7 cells treated with E2 (control E2(+)), steroid-depleted JMJD2B-depleted MCF-7 cells (siJ2B E2(-)), and JMJD2B-depleted MCF-7 cells treated with E2 (siJ2B E2(+)).
