Breast cancer cells reexpressing estrogen receptor alpha response to 17beta-estradiol

Analysis of the response of estrogen receptor (ER) negative MDA-MB-231 breast cancer cells infected with full-length ER alpha adenoviral constructs to treatment with 17beta-estradiol (E2). Results provide insight into the anti-proliferative effect of E2 on breast cancer cells reexpressing ER.

Anti-prolif. effect of E2 in breast cancer cells that re-exp. ERalpha is mediated by aberr. regulat. of cell cycle genes

(Submitter supplied) Gene expression changes caused by estrogen treatment of breast cancer cells that re-express ERalpha was investigated by infecting ER-negative MDA-MB-231 breast cancer cells for 24 h with recombinant adenovirus encoding full-length human ERalpha (Ad-ERalpha) or control vector (Ad-LacZ), and treating them with 0·01% ethanol (vehicle control) or 10-8 M 17beta-estradiol (E2). After 48 h of treatment, total RNA was isolated and used for transcript profiling on Affymetrix GeneChips. more...

Estrogen regulation and physiopathologic significance of alternative promoters in breast cancer

(Submitter supplied) Alternative promoters (APs) occur in >30% protein-coding genes and contribute to proteome diversity. However, large-scale analyses of AP regulation are lacking, and little is known about their potential physiopathologic significance. To better understand the transcriptomic impact of estrogens, which play a major role in breast cancer, we analyzed gene and AP regulation by estradiol in MCF7 cells using pan-genomic exon arrays. more...

Novel Estrogen Receptor-{alpha} Binding Sites and Estradiol Target Genes Identified by ChIP Cloning in Breast Cancer.

(Submitter supplied) Estrogen receptor-{alpha} (ER{alpha}) and its ligand estradiol play critical roles in breast cancer growth and are important therapeutic targets for this disease. Using chromatin immunoprecipitation (ChIP)-on-chip, ligand-bound ER{alpha} was recently found to function as a master transcriptional regulator via binding to many cis-acting sites genome-wide. Here, we used an alternative technology (ChIP cloning) and identified 94 ER{alpha} target loci in breast cancer cells. more...

Analysis of estrogen receptor (ER) alpha positive MCF-7 breast cancer cells overexpressing constitutively active Raf-1, constitutively active MEK, constitutively active c-erbB-2, or ligand-activatable EGFR. Results indicate that increased MAPK activation results in loss of ER-alpha expression.

Estrogen effects on MCF-7 breast cancer cells co-expressing ERa and ERb

(Submitter supplied) Two subtypes of the estrogen receptor, ERalpha and ERbeta, mediate the actions of estrogens, and the majority of human breast tumors contain both ERalpha and ERbeta. To examine the possible interactions and modulatory effects of ERbeta on ERalpha activity, we have used adenoviral gene delivery to produce human breast cancer (MCF-7) cells expressing ERbeta, along with their endogenous ERalpha. We have examined the effects of ERβ expression on genome-wide gene expression by Affymetrix GeneChip microarrays. more...

Gene Regulation by Estrogen Signaling and DNA Methylation in MCF7 Breast Cancer Cells

(Submitter supplied) Estrogen signaling and epigenetic modifications, in particular DNA methylation, are involved in regulation of gene expression in breast cancers. Here we investigated a potential regulatory cross-talk between these two pathways by identifying their common target genes and exploring potential underlying molecular mechanisms in human MCF7 breast cancer cells. Principal Findings: Gene expression profiling revealed that the expression of approximately 150 genes was influenced by both 17β-estradiol (E2) and a hypomethylating agent 5-aza-2’-deoxycytidine (DAC). more...

An estrogen-dependent model of breast cancer created by transformation of normal human mammary epithelial cells

(Submitter supplied) This study was performed to check that ESR1 and BMI1 are biologically active after lentiviral transduction of primary human mammary epithelial cells (HMECs) with lentiviral vectors expressing ESR1 and BMI1 from the human PGK promoter. ESR1 targets like PGR, PRLR and GREB1, but not TFF1 and XBP1, were induced by estradiol in the ESR1-expressing cells. BMI1 targets like BMI1, NEFL and CCND2 were repressed in the BMI1-expressing cells. more...

Overlapping and distinct functions between ERα and ERβ homodimers and corresponding transcriptomes in the same cellular context

(Submitter supplied) The two estrogen receptors, ERα and ERβ function as ligand-inducible transcription factors. Most in vitro studies have reported that ERα drives breast cancer growth whereas ERβ, if expressed, suppresses growth. To dissect function and gene expression profile regulated by ERα or ERβ, respectively, we generated a novel cell model expressing only ERβ, by applying CRISPR-cas9 to delete ERα in MCF7 cells with stable Tet-Off-inducible ERβ expression. more...

Genomic analyses of breast cancer cells: 17β-hydroxysteroid dehydrogenase type 1 induces transcriptional changes in estradiol-dependent and independent manners

(Submitter supplied) 17β-HSD1 expression modulates T47D transcript profile in in steroid-deprived medium. The enzyme specifically regulates apoptosis and cancer-related genes in T47D cells cultured in steroid-deprived medium. Genes that primarily involved in Cell cycle progression, such as the Cyclin A2 gene, CCNA2, are generally down-regulated whereas most genes involved in apoptosis and cell death, such as the proapoptotic gene XAF1 and FGF12, are on the contrary up-regulated by 17β-HSD1 knockdown, and 21% of the modulated genes belong to this latter functional category. more...

Time-course effect of estradiol and estradiol-BSA on early gene expression in SKBR3 cells

(Submitter supplied) Estrogens have been reported to activate several processes via membrane binding to either classic estrogen receptors (ERs) or GPR30. We have used either estradiol or BSA-conjugated estradiol in order to initiate membrane-initiated actions and ICI 172,780 (ICI) or G15 to explore ER- and GPR30-related transcription. Our results show that the majority of G15-inhibited transcription is depending on ERs, as it is also inhibited by ICI. more...
