The effect of bisphenol A on human prostaspheres derived from primary prostate epithelial cells

ABSTRACT: 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. 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'.

BPA impacts on HEK 293 cells

Project description:Bisphenol A (BPA) is an environmental endocrine disruptor which has been detected in almost all human bodies. Many studies have implied that BPA exposure is harmful to human health. Previous studies mainly focused on BPA effects on ER-positive cells. Genome-wide impact of BPA on gene regulation in ER-negative cells is unclear. In the present study, we performed RNA-seq to characterize BPA-induced gene regulation on ER-negative HEK 293 cells.

The m6A methyltransferase METTL3 participate in the attenuated effect of BPA on learning and memory in rat

Project description:Bisphenol A (BPA), a widely used endocrine disruptor, has been implicated in cognitive impairment via epigenetic machinery. N6-methyladenosine (m6A) has recently emerged as a new epigenetic factor that negatively influencing cognition, but the role of m6A in BPA induced cognitive deficits has not been explored yet.Here, m6A sequencing in total RNA of neurons after BPA exposure was performed and compare.

Maternal exposure to bisphenol-A during pregnancy increases pancreatic beta-cell growth during early life in male mice offspring

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.

Sox9 mediated differential gene expression was assessed in prostaspheres derived from urogenital sinus epithelial cells

Project description:Prostate cancer is one of the most common malignancies and the second leading cause of death from cancer in men. The molecular mechanisms driving prostate carcinogenesis are complex; with several lines of evidence suggesting that the re-expression of conserved developmental programs play a key role. Through conditional gene targeting and organ grafting, we describe conserved roles for the transcription factor Sox9 in the initiation of both prostate organogenesis and prostate carcinogenesis in murine models. Abrogation of Sox9 expression prior to the initiation of androgen signaling blocks the initiation of prostate development. Similarly, Sox9 deletion in two genetic models of prostate cancer (TRAMP and Hi-Myc) blocks cancer initiation. Expression profiling of Sox9-null prostate epithelial cells reveals that the role of Sox9 in the initiation of prostate development may relate to its regulation of multiple cytokeratins and/or calcium-related proteins. Due to its essential role in cancer initiation, manipulation of Sox9 targets in at-risk men may prove useful in the chemoprevention of prostate cancer. Sox9 differential gene expression in prostaspheres derived from the urogenital sinus epithelium was assessed by tow-colors direct comparisons of labeled moieties. Hybridizations were performed on the Agilent (Santa Clara, CA) Whole Mouse Genome DNA microarray (mgug4122a). Sox9 targets were assessed in murine prostate epithelial cells with targeted deletion.

Preferential Epigenetic Programming of Estrogen Response after in utero xenoestrogen (bisphenol-A) exposure [NimbleGen]

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.

Effects of Korean red ginseng against the influence of bisphenol A on ovariectomized mouse liver and uterus

Project description:Bisphenol A (BPA), known as an endocrine disruptor, is widely used in the world. BPA is reported to cause inflammation-related diseases. Although efforts to identify the effects of BPA are ongoing, the impact of BPA on postmenopausal women is not well known. Korean red ginseng (KRG) has been used safely in human for a long time for the treatment of diverse diseases. KRG has been reported of its mitigating effect on menopausal symptoms and suppress adipose inflammation. Here, we investigate the protective effect of orally administered KRG on the impacts of BPA in the liver and uterus of menopausal mouse model.

Preferential Epigenetic Programming of Estrogen Response after in utero xenoestrogen (bisphenol-A) exposure [Illumina]

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:In this study we compared the global transcriptomic response of human ovarian cells to zeralenone (ZEA; mycotoxin) and bisphenol A (BPA; plastic additive) with the effect of physiological estradiol (E2). For this purpose we applied the PEO1 human ovarian cell line that was treated with 10 nM ZEA, 100 nM BPA and 10 nM E2. Transcriptomic profile was compared by mRNA sequencing (Illumina NextSeq 500).
