Project description:Neurosphere cultures prepared from E14.5 mouse cerebral cortex at passage 3 were treated for 4 hours with 100 nM dexamethasone We used microarrays to detail the global program of dexamethasone regulated gene expression in embryonic neural progenitor/stem cells. Cerebral cortex was isolated from E14.5 mouse fetuses and cultured as neurospheres for 3 passages prior to treatment with 100 nM dexamethasone or ethanol vehicle for 4 hours.

Project description:The objective of this study was to determine the extent to which paracrine action of 17-beta-estradiol on ER+ mouse astrocytes, affect gene expression of MDA231-derived brain trophic 231BR cells. Microarray analysis was performed in triplicate samples from 231BR cells treated with vehicle (OH), 10nM Estradiol (E2), alone or in combination with mouse astrocytes. 231BR-EGFP cells were sorted after 24h co-culture.

Project description:Complex autoimmune diseases are sexually dimorphic. An interplay between predisposing genetics and sex-related factors likely determines the sex discrepancy in the immune response, but conclusive evidence regarding the underlying molecular mechanisms is lacking. Using forward genetics, we positionally identified a polymorphic estrogen receptor binding site that regulates CD2 expression, leading to female-specific differences in mouse models of T cell-dependent autoimmunity. Female mice with reduced CD2 levels displayed a diminished T cell activation and autoimmune T cell response. Mechanistically, CD2 affected LAG-3 expression. Our findings help to explain the sexual dimorphism in human autoimmunity, as CD2 associated with rheumatoid arthritis and its regulation through 17-β-estradiol was conserved in human T cells. Hormonal regulation of CD2 has implications for CD2-targeted therapy. Indeed, anti-CD2 treatment more potently affected female mice. In conclusion, our results demonstrate the relevance of sex-genotype interactions and deliver strong evidence for CD2 as a sex-sensitive predisposing factor in autoimmunity.

Project description:We have previously demonstrated that endoxifen is the most important tamoxifen metabolite responsible for eliciting the anti-estrogenic effects of this drug in breast cancer cells expressing estrogen receptor-alpha. However, the relevance of estrogen receptor-beta in mediating endoxifen action has yet to be explored. Therefore, the goals of this study were to determine the differences in the global gene expression profiles elicited by estradiol treatment and endoxifen between parental MCF7 breast cancer cells (expressing estrogen receptor alpha only) and MCF7 cells stably expressing estrogen receptor beta. Total RNA was isolated from parental or estrogen-receptor beta expressing MCF7 cells following 24 hour treatments with either ethanol vehicle, 1nM 17-beta-estradiol or 1nM estradiol plus 40nM endoxifen. All studies were conducted in biological replicates of 2.

Project description:Human estrogen-responsive breast cancer cell line MCF-7 wt were used to produce stable clones expressing ER-beta tagged with TAP-tag respectively at the C-term and at the N-term (Ct-ER-beta and Nt-ER-beta) as previously described. MCF7 wt and beta clone cells were cultured in steroid-free medium for 5 days and then were treated with 10nM of 17-beta-estradiol, or vehicle (ETOH). RNA was extracted after 2h, 4h and 8h of stimulation with 17-ß-estradiol 10 nM (+E2) or ethanol vehicle . Total RNA extracted by Ct-ER-beta and Nt-ER-beta cells were pooled (TAP-ER-beta). For mRNA expression profiling, 500 ng total RNA were reverse transcribed and used for synthesis of cDNA and biotinylated cRNA. Finally cRNA were hybridized for 18 hours on Illumina HumanHT-12 v3.0 BeadChips and after scanning, data analysis was performed.

Project description:Studies of gene expression profiles using the whole genome wide microarray analysis in SUM149PT cells (ER-, p53mut) and SUM190PT cells (ER-, p53mut) when treated with 5 or 7.5 uM CG-1521 alone and in combination with 10 nM 17beta-estradiol. Comparisons between each treatment group provides evidence for the dysregulation of genes associated with the spindle assembly checkpoint. Three independent experiments were carried out in SUM149PT and SUM190PT cells, which were treated with vehicle (ethanol/DMSO), 10nM 17beta-estradiol, 5 or 7.5 uM CG-1521, and the combination of 17 beta-estradiol and CG-1521. Total RNA was extracted from cell lysates using QIAGEN RNeasy mini kit after 48h of treatment.

Project description:Background: Prenatal exposure to air pollutants is associated with increased risk for neurodevelopmental and neurodegenerative disorders. However, few studies have identified transcriptional changes related to air pollutant exposure. Methods: RNA sequencing was used to examine transcriptomic changes in blood and cerebral cortex of three male and three female mouse neonates prenatally exposed to traffic-related nano-sized particulate matter (nPM) compared to three male and three female mouse neonates prenatally exposed to control filter air. Results: We identified 19 nPM-associated differentially expressed genes (nPM-DEGs) in blood and 124 nPM-DEGs in cerebral cortex. The cerebral cortex transcriptional responses to nPM suggested neuroinflammation involvement, including CREB1, BDNF, and IFN γ genes. Both blood and brain tissues showed nPM transcriptional changes related to DNA damage, oxidative stress, and immune responses. Three blood nPM-DEGs showed a canonical correlation of 0.98 with 14 nPM-DEGS in the cerebral cortex, suggesting a convergence of gene expression changes in blood and cerebral cortex. Exploratory sex-stratified analyses suggested a higher number of nPM-DEGs in female cerebral cortex than male cerebral cortex. The sex-stratified analyses identified 2 nPM-DEGs (Rgl2 and Gm37534) shared between blood and cerebral cortex in a sex-dependent manner. Conclusions: Our findings suggest that prenatal nPM exposure induces transcriptional changes in the cerebral cortex, some of which are also observed in blood. Further research is needed to replicate nPM-induced transcriptional changes with additional biologically relevant time points for brain development.

Project description:Five ovariectomized (OVX) Brown Norway rats (Charles Rivers Laboratories, Wilmington, DE, USA) weighing 200-250 g received 10 µL of 17β-estradiol (E2) eye drops once daily in both eyes for three weeks [20]. The eye drops contained 0.1% (w/v) E2 in saline vehicle containing 20% (w/v) 2-hydroxypropyl-β-cyclodextrin. Five OVX control rats received 10 µL of this vehicle as eye drops for the same dosing regimen and duration. After 24 h of the last treatment, the animals were euthanized by CO2 overexposure, and their eyes were immediately enucleated followed by the isolation of the retina. The tissue samples were rinsed with saline and, then, blotted dry for preparation to label-free shotgun proteomic analyses. All procedures involving animals were reviewed and approved by the Institutional Animal Care and Use Committee at the University of North Texas Health Science Center before the initiation of the studies (approval number: 2018-0028).
