Gene Expression Analysis of Human Endometrial Endothelial Cells Exposed to Bisphenol A

ABSTRACT: The endocrine disrupting chemical bisphenol A (BPA) can affect reproductive organs, tissues and cells in several species. Treatment of human endometrial endothelial cells (HEECs) with 50 µM BPA decreased their proliferation compared with the control. Microarray analyses revealed that BPA affected biological processes such as the cell cycle, cell division, and cytoskeleton organization, confirming the results of the proliferation assay. Expression of three of the most differentially expressed genes identified in the microarray analysis was verified by real-time quantitative reverse transcription polymerase chain reaction in five HEEC cultures obtained from women in the proliferative phase and in five cultures obtained from women in the secretory phase of the menstrual cycle after treatment with BPA. The present study supports our previous findings of decreased proliferation and increased cell death in response to BPA, and may offer important clues to the mechanisms of action of BPA. Keywords: Exposure analysis

Gene Expression Analysis of Human Endometrial Endothelial Cells Exposed to Bisphenol A

Project description:The endocrine disrupting chemical bisphenol A (BPA) can affect reproductive organs, tissues and cells in several species. Treatment of human endometrial endothelial cells (HEECs) with 50 ÂµM BPA decreased their proliferation compared with the control. Microarray analyses revealed that BPA affected biological processes such as the cell cycle, cell division, and cytoskeleton organization, confirming the results of the proliferation assay. Expression of three of the most differentially expressed genes identified in the microarray analysis was verified by real-time quantitative reverse transcription polymerase chain reaction in five HEEC cultures obtained from women in the proliferative phase and in five cultures obtained from women in the secretory phase of the menstrual cycle after treatment with BPA. The present study supports our previous findings of decreased proliferation and increased cell death in response to BPA, and may offer important clues to the mechanisms of action of BPA. Keywords: Exposure analysis Two-condition experiments, BPA-exposed vs. control HEEC. Biological replicates: 5 HEEC cultures, independently grown, exposed and harvested. One replicate per array. Dye-swaps for exposed and reference samples between replicates.

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.

Genome-wide expression analysis of autologous eutopic and ectopic endometrium from fertile Indian women with endometriosis

Project description:Whole genome expression analyses of autologous, paired eutopic and ectopic endometrial samples obtained during proliferative and secretory phases of menstrual cycles from eighteen (n=18) fertile women suffering from confirmed stage 3 (moderate) and stage 4 (severe) ovarian endometriosis were performed using whole human genome oligo microarray Agilent paltform (Cat. No. G4112F). In the present study, genome-wide expression analysis of autologous, paired eutopic and ectopic endometrial samples obtained during proliferative (n=13) and secretory (n=5) phases of menstrual cycle from fertile women (n=18) suffering from moderate (stage 3; n=8) or severe (stage 4; n=10) endometrioma was performed by using Agilent single color oligo microarray platform (G4112, 4X44K). Thus eighteen (18) eutopic (shown as EU) and eighteen (18) ectopic (shown as EC) samples from eighteen (18) subjects with confirmed menstrual phase (proliferative and secretory) and severity stages (stage 3 and stage 4) were studied.

Bisphenol B and bisphenol AF exposure enhances uterine diseases risks in mouse

Project description:Bisphenol A (BPA) analogs, bisphenol B (BPB) and bisphenol AF (BPAF) have been widely detected in the environment and human products with increasing frequency. However, uterine health risks caused by BPBBisphenol A (BPA) analogs, bisphenol B (BPB) and bisphenol AF (BPAF) have been widely detected in the environment and human products with increasing frequency. However, uterine health risks caused by BPB and BPAF exposure need to be further elucidated. The study aimed to explore whether BPB or BPAF exposure will induce adverse outcomes in uterus. We then performed gene expression profiling using data obtained from mouse uterus exposed to BPB and BPAF at 28 days.

Biological significance of CDYL in endometrial receptivity

Project description:Impaired endometrial receptivity is one of the major causes of recurrent implantation failure (RIF), and the underlying molecular mechanism has not been fully elucidated. We demonstrated that Chromodomain Y like (CDYL) was highly expressed in the endometrium at mid-secretory phase during the normal menstrual cycles. However, the expression of CDYL was down-regulated in the endometrial tissues obtained from women with RIF, consistently with the protein level of LIF, which is the marker of endometrial receptivity. Knockdown of CDYL significantly decreased the cell migration of human endometrial Ishikawa cells and primary endometrial cells. Genomic analyses revealed that CDYL gene silencing resulted in decreased expression of many genes associated with cytoskeleton and migration regulation.

Consequences of perinatal bisphenol A exposure in a mouse model of multiple sclerosis

Project description:Multiple sclerosis (MS) is a complex disease influenced by genetic and environmental contributing factors. Endocrine disrupting compounds (EDCs) such as bisphenol A (BPA) affect gene expression and hormone-regulated systems throughout the body. We investigated the effects of BPA on Theiler’s-virus induced demyelination (TVID), a mouse model of MS. Perinatal BPA exposure, combined with viral infection, resulted in a decreased level of viral antibodies, accelerated the onset of TVID symptoms, increased inflammation in both the spinal cord and digestive tract, and amplified immune-related gene expression changes induced by viral infection. These results demonstrate the effect of BPA on the trajectory of TVID, and illustrate how multiple factors collectively influence autoimmune disease. For microarray: 7 samples

Zebrafish toxicogenomics and phenotypic analyses reveal molecular insights into bisphenol-A (BPA) early-life exposure toxicity.

Project description:In this study, developing zebrafish were exposed to 500-4500 Âµg/L BPA for 7 days from 3 hours post-fertilization for a microarray experiment to obtain molecular insights into BPA early-life exposure toxicity. We analyzed a total of 18 arrays; five biological replicate arrays for zebrafish treated with 500 Âµg/L BPA, four biological replicate arrays for zebrafish treated with 1500 Âµg/L BPA, four biological replicate arrays for zebrafish treated with 4500 Âµg/L BPA against 5 biological replicate arrays for control fish. A common reference sample was used for both treated and control samples.

Plasma microRNA profiles in women with and without endometriosis at different menstrual cycle phases

Project description:The objectives of the study: 1. Does the phase of the menstrual cycle alter microRNA (miRNA) plasma profiles in healthy women of reproductive age and in women with endometriosis? 2. Does this alter prospects for development of a miRNA-based diagnostic test for endometriosis? Prospectively recruited asymptomatic control women and women with surgically diagnosed endometriosis (n = 8 in each group) were included. Each patient provided blood samples in the early proliferative, late proliferative and mid luteal phases of the menstrual cycle (n = 47 total plasma samples). The cycle phase was verified by hormonal profile. RNA was extracted from each sample and expression of microRNAs was assessed using TaqMan Low Density Human miRNA arrays.
