Gene expression profiling in T-47D breast cancer cells following inducible expression of estrogen receptor beta

ABSTRACT: T-47D breast cancer cells were stably transfected with a tet-off inducible construct encoding estrogen receptor beta. Microarray experiments were carried out at multiple time points 1-30 hours following treatment with estradiol and under induction and non-induction conditions. Keywords: Inducible expression of ERbeta

RNA-seq of T-47D cells treated with 17-beta-estradiol and/or APOBEC3B-targeting siRNA

Project description:Apolipoprotein B mRNA-editing enzyme catalytic polypeptide-like 3 (APOBEC3B, A3B) is a key molecular driver inducing mutations in multiple human cancer. A3B belongs to the APOBEC3 enzyme family, which consists seven closely related DNA deaminases that catalyse cytosine-to-uracil (C>U) editing of single-stranded DNA (ssDNA). Here, we used RNA-seq technology to study the effect of A3B knockdown on the effect of estradiol induction in T-47D cells.

Expression data for tet-on inducible mouse p53 stable line in H1299 cells

Project description:In order to identify novel genes regulated by p53, stable line containing tet-on inducible p53 construct was generated and used for gene expression analysis. Tet-on p53 inducible stable line was induced by doxycyclin for 24 hours before total RNA was extracted for array analysis.

Estrogen-regulated gene expression in human osteosarcoma cells stably transfected with estrogen receptor alpha or beta

Project description:Estrogens exert many important effects in bone, a tissue that contains both estrogen receptors alpha and beta (ERalpha and ERbeta). To compare the actions of these receptors, we generated U2OS human osteosarcoma cells stably expressing ERalpha or ERbeta, at levels comparable to those in osteoblasts, and we characterized their response to estradiol (E2) over time using Affymetrix GeneChip microarrays to determine the expression of approximately 12,000 genes, followed by quantitative PCR verification of the regulation of selected genes. Of the ca. 100 regulated genes we identified, some were stimulated by E2 equally through ERalpha and ERbeta, whereas others were selectively stimulated via ERalpha or ERbeta. The E2-regulated genes showed three distinct temporal patterns of expression over the 48 h time course studied. Of the functional categories of the E2-regulated genes, most numerous were those encoding cytokines and factors associated with immune response, signal transduction, and cell migration and cytoskeleton regulation, indicating that E2 can exert effects on multiple pathways in these osteoblast-like cell lines. Of note, E2 up-regulated several genes associated with cell motility selectively via ERbeta, in keeping with the selective E2 enhancement of the motility of ERbeta-containing cells. On genes regulated equally by E2 via ERalpha or ERbeta, the phytoestrogen genistein preferentially stimulated gene expression via ERbeta. These studies indicate both common as well as distinct target genes for these two ERs, and identify many novel genes not previously known to be under estrogen regulation. Keywords: other

Selective estrogen receptor-beta agonists repress transcription of proinflammatory

Project description:In addition to their role in the development and function of the reproductive system, estrogens have significant anti-inflammatory properties. Although both estrogen receptors (ERs) can mediate anti-inflammatory actions, ERbeta is a more desirable therapeutic target because ERalpha mediates the proliferative effects of estrogens on the mammary gland and uterus. In fact, selective ERbeta agonists have beneficial effects in preclinical models involving inflammation without causing growth-promoting effects on the uterus or mammary gland. However, their mechanism of action is unclear. The purpose of this study was to use microarray analysis to determine whether ERbeta-selective compounds produce their anti-inflammatory effects by repressing transcription of proinflammatory genes. We identified 49 genes that were activated by TNF-alpha in human osteosarcoma U2OS cells expressing ERbeta. Estradiol treatment significantly reduced the activation by TNF-alpha on 18 genes via ERbeta or ERalpha. Most repressed genes were inflammatory genes, such as TNF-alpha, IL-6, and CSF2. Three ERbeta-selective compounds, ERB-041, WAY-202196, and WAY-214156, repressed the expression of these and other inflammatory genes. ERB-041 was the most ERbeta-selective compound, whereas WAY-202196 and WAY-214156 were the most potent. The ERbeta-selective compounds repressed inflammatory genes by recruiting the coactivator, SRC-2. ERB-041 also repressed cytokine genes in PBMCs, demonstrating that ERbeta-selective estrogens have anti-inflammatory properties in immune cells. Our study suggests that the anti-inflammatory effects of ERB-041 and other ERbeta-selective estrogens in animal models are due to transcriptional repression of proinflammatory genes. These compounds might represent a new class of drugs to treat inflammatory disorders. Keywords: estrogen receptor, gene regulation, TNF

TET-Mediated DNA Demethylation is Required for Inducible Vasculogenic Reprogramming of the Skin

Project description:Tissue nanotransfection (TNT) based topical electrophoretic delivery of Etv2, Foxc2, and Fli1 (EFF) plasmids achieve induced vasculogenesis (iV) in the skin by inducing vasculogenic fibroblasts (VF). scRNA-seq analysis revealed TET-dependent gain of VF in dermal fibroblasts in response to EFF. Emergence of VF required TET-dependent demethylation of fibroblast-borne endothelial genes in vivo. Fibroblast-specific inducible overexpression of EFF in TARGATT mice caused induction of TET1/2/3, followed by transition of fibroblast to VF in vivo. TET induction was associated with elevated 5-hmC abundance in VF. TET-dependent demethylation of fibroblast-borne endothelial genes caused the formation of VF and rescued perfusion in diabetic ischemic limbs. TNTEFF rescued perfusion and closure of diabetic wounds. TET enzymes, suppressed in diabetics, play a pivotal role in causing endogenous EFF-induced VF state change of skin fibroblasts. TNT delivery of EFF transcription factors upregulate TET expression. This work is the first to recognize the significance of TET in the inducible formation of blood vessels to rescue diabetic ischemic tissue.

Histone variants and modification in T-47D cells

Project description:To investigate the impact of histone variants and modification on gene regulation, we report high-throughput profiles of six histone markers, H2A.Z, H3K4me2, H3K9me3, H3K27me3, H3K27ac, and H3K36me3, by ChIP-Seq in T-47D breast cancer cells.
