Transcriptome analysis of bisphenol A (BPA) treated Y79 human retinoblastoma cells

Project description:Purpose: finding differential transcripts usage in environmentally harzardous chemical, bisphenol A (BPA) in human retinal cells Methods: transcriptome analysis by the RNA-seq via mRNA pull-down Results: We found that BPA increases cellular toxicity by the increasing of early apoptotic pathway in Y79 cells. Also, over thounds of retained intron events were detected from the RNA-seq analysis. Conclusions: Bisphenol A (BPA) increases early cytotoxic effects in Y79 cells through the early apoptotic pathway and changes the context of trascript through the splicing regulation mechanisms.

Project description:Retinoblastoma Y79 cell line was treated with scopoletin in vitro and RNA was isolated for microarray experiment to study the changes in the whole gene expression profiling in the Y79 cell line. The study identified 1675 up-regulated genes (>1.0 fold) and 1879 down-regulated genes (<-1 fold) in response to scopoletin treatment

Transcription profiling of mice testicular sertoli cells from transgenic mice harboring a temperature-sensitive simian virus 40 large T-antigen a treated with bisphenol A to investigate the mechanisms by which bisphenol A (BPA) induces cell death

Project description:We performed global scale microarray analysis to identify detailed mechanisms by which bisphenol A (BPA) induce cell death by using an Affymetrix GeneChip system. Testicular Sertoli TTE3 cells used in the present study were derived from transgenic mice harboring a temperature-sensitive simian virus 40 large T-antigen. Cell death accompanying endoplasmic reticulum stress was observed in the cells treated with 0.2 mM BPA. Of the 22,690 probe sets analyzed, approximately 1,300 genes were down- and up-regulated by a factor of 2.0 or greater in the cells treated with BPA. TTE3 cells were treated with BPA for 0, 3, 6, and 12 h. Total RNA samples were prepared from the cells. Gene expression was analyzed by an Affymetrix GeneChip® system with the Mouse Expression Array 430A which was spotted with 22,690 probe sets. Sample preparation for array hybridization was carried out as described in the manufactures instructions.

Whole genome microarray of T lymphoma invasion and metastasis (Tiam1) silenced retinoblastoma Y79 cells

Project description:We hypothesized that Tiam1 is involved in invassiveness of retinoblastoma. The fuctional role of Tiam1 in cell progression and metastasis was tested by siRNA mediated knockdown of Tiam1 in retinoblastoma Y79 cells. The genes de-regulated in response to Tiam1 knockdown was analysed by cDNA microarray in which most of the actin cytoskeleton regulation proteins and apoptotic proteins were de-regulated. our results prove that Tiam1 modulates actin cytoskeleton and cell invasion in retinoblastoma. Retinoblastoma Y79 cells were treated with Tiam1 siRNA for 48hrs and cDNA microarray was performed to analyze the genes regulated by Tiam1 silencing compared to untreated Y79 cells. Experiments were performed in triplicates.

Genome-wide analysis of low dose bisphenol-A (BPA) exposure in human prostate cells

Project description:Endocrine disrupting compounds (EDCs) have the potential to cause adverse effects on wildlife and human health. Two important EDCs are the synthetic estrogen 17a-ethynylestradiol (EE2) and bisphenol A (BPA) both of which are xenoestrogens (XEs) as they bind the estrogen receptor and disrupt estrogen physiology in mammals and other vertebrates. In recent years the influence of XEs on oncogenes, specifically in relation to breast and prostate cancer has been the subject of considerable study. In this study healthy primary human prostate epithelial cells (PrECs) were exposed to environmentally relevant concentrations of BPA (5nM and 25nM BPA) and interrogated using a whole genome microarray. Microarray data were analyzed using the Pipeline for Integrated Microarray Expression and Normalization Toolkit (PIMENTo) that provides (1) data pre-processing, (2) and normalization to remove the technical variability across arrays data, (3) data visualization, (4) background subtraction, (5) quality control, and (6) differential expression (DE) analysis using the Bioconductor package 'limma'. Exposure to 5 and 25nM BPA generated 8,876 and 9,525 differentially expressed (DE) genes respectively in treated PrECs. Exposure to EE2 had the greatest effect on the PrEC transcriptome (2,389 DE genes) and all three exposures shared 7,011 common DE genes. Together, the low and high dose of BPA affected 1,839 genes not shared with the EE2 exposure.

Transcriptome profiling of adult cardiac tissue of control versus overfed female sheep prenatally treated with bisphenol A

Project description:Developmental programming is the concept that environmental factors during fetal growth can alter development, metabolism and physiology of an organism, thus diseases can be programmed by intrauterine influences. The fetal origin of health and disease hypothesis has received strong support from experimental studies in animals including livestock species. Using a sheep model, it has been shown that developmental changes of ewe offspring may be susceptible to maternal pregnancy bisphenol A (BPA) treatment. For example, prenatally BPA treated female offspring tended to have reduced birth weight. In this study we sought to identify gene expression differences in ewe offspring as a result of maternal pregnancy BPA treatment on a control or high-caloried diet. Samples of heart tissues were collected during the second breeding season, allowing us to examine gene expression changes in ewes prenatally treated with BPA and maturing under the different diets.

In vivo effects of short-term treatment with Bisphenol A (BPA) on mice pancreatic islets

Project description:Bisphenol-A (BPA) is one of the most widespread endocrine disrupting chemicals (EDC) used as the base compound in the manufacture of polycarbonate plastics. Although evidence points to consider exposure to BPA as a risk factor for the development of Diabetes, its actions on whole body metabolism and on pancreatic beta cells are still unclear. The aim of this study was to study the in vivo effects of BPA on mice pancreatic islets, particularly on how it could regulate ion channels expression and function. And thus, bringing mechanistic insight into the suggested association between BPA exposure and health disorders. We used microarrays to detail the global profile of gene expression to identified different groups of up and down-regulated genes in the work model, with a special focus on genes related to ion channel-mediated actions of BPA in mice pancreatic β-cells.
