Project description:Bisphenol-A (BPA) is an environmentally ubiquitous estrogen-like endocrine-disrupting compound. Exposure toBPAin utero hasbeen linked tofemale reproductive disorders, including endometrial hyperplasiaandbreast cancer. Estrogens are an etiological factor in many of these conditions. We sought to determine whether in utero exposure to BPA altered the globalCpGmethylation pattern of the uterine genome, subsequent gene expression, and estrogen response.Pregnantmicewere exposed to an environmentally relevant dose of BPAorDMSOcontrol.Uterine DNAand RNAwere examined by usingmethylatedDNAimmunoprecipitationmethylation microarray, expression microarray, and quantitative PCR. In utero BPA exposure altered the global CpG methylation profile of the uterine genome and subsequent gene expression. The effect on gene expression was not apparent until sexual maturation, which suggested that estrogen response was the primary alteration. Indeed, prenatal BPA exposure preferentially altered adult estrogen-responsive gene expression. Changes in estrogen response were accompanied by altered methylation that preferentially affected estrogen receptor-a (ERa)–binding genes. The majority of genes that demonstrated both altered expression and ERa binding had decreased methylation. BPA selectively altered the normal developmental programming of estrogen-responsive genes via modification of the genes that bind ERa. Gene– environment interactions driven by early life xenoestrogen exposure likely contributes to increased risk of estrogenrelateddisease in adults.—Jorgensen, E. M.,Alderman,M.H., III,Taylor, H. S.

Project description:Bisphenol-A (BPA) is an environmentally ubiquitous estrogen-like endocrine-disrupting compound. Exposure toBPAin utero hasbeen linked to female reproductive disorders, including endometrial hyperplasia and breast cancer. Estrogens are an etiological factor in many of these conditions. We sought to determine whether in utero exposure to BPA altered the global CpG methylation pattern of the uterine genome, subsequent gene expression, and estrogen response. Pregnant mice were exposed to an environmentally relevant dose of BPA or DMSO control. Uterine DNA and RNA were examined by using methylated DNA immunoprecipitation methylation microarray, expression microarray, and quantitative PCR. In utero BPA exposure altered the global CpG methylation profile of the uterine genome and subsequent gene expression.

Project description:Bisphenol A is an environmental xenoestrogen commonly known as an endocrine disruptor. We previously reported BPA-treated human primary prostate epithelial cell derived prostaspheres had larger size, exhibited clonogenicity, and showed increase in stem cell marker expression. Results reveal the molecular basis of BPA action in human prostate stem-progenitor cells.

We previously reported BPA-treated human primary prostate epithelial cell derived prostaspheres had larger size, exhibited clonogenicity, and showed increase in stem cell marker expression. Results reveal the molecular basis of BPA action in human prostate stem-progenitor cells. Human primary prostate epithelial cells from three disease-free Caucasian donors formed prostaspheres from single stem-like cells in matrigel cultures and were treated with 0.1 nM estradiol-17β (E2), 10 nM (B10), 200 nM (B200), and 1000 nM bisphenol A (BPA) for 7 days. The vehicle-treated prostaspheres were used as 'untreated controls'.

Project description:Bisphenol-A is a widespread endocrine disruptor chemical. In utero or perinatal exposure to bisphenol-A (BPA), leads to impaired glucose metabolism during adulthood. To investigate the consequences of the exposure to bisphenol-A during development in pancreatic beta-cell growth We used microarrays to determine gene expression changes resulting from exposure to bisphenol-A during pregnancy in pancreatic islets of the male offspring at postnatal day 30.

Project description:Plasticizers with estrogenic activity, such as bisphenol A (BPA), have been reported to have potential adverse health effects in humans, especially in fetal and infant stages. Due to mounting evidence and public pressure BPA is being phased out by the plastics manufacturing industry and is being replaced by other bisphenol variants in “BPA-free” products. We have compared estrogenic activity of 7 bisphenol analogues (BPA; bisphenol S, BPS; bisphenol F, BPF; bisphenol AP, BPAP; bisphenol AF, BPAF; bisphenol Z, BPZ; bisphenol B, BPB) in human breast cancer cell lines. We used microarrays to detail the alterations in gene expression profiles associated with MCF-7 cell line exposure to bisphenol A analogues
