In vitro transcriptomic analyses reveal pathway perturbations, estrogenic activities, and potencies of data-poor BPA alternative chemicals

Project description:Since initial regulatory action in 2010 in Canada, bisphenol A (BPA) has been progressively replaced by structurally related alternative chemicals. Unfortunately, many of these chemicals are data-poor, limiting toxicological risk assessment. We used high-throughput transcriptomics to evaluate potential hazards and compare potencies of BPA and 15 BPA alternative chemicals in cultured breast cancer cells. MCF-7 cells were exposed to BPA and 15 alternative chemicals (0.0005 – 100 µM) for 48 hrs. TempO-Seq sequencing (BioSpyder Inc.) was used to examine general toxicological effects and estrogen receptor alpha (ERα)-associated transcriptional changes. Benchmark concentration (BMC) analysis was conducted to identify two global transcriptomic points of departure (tPODs): (a) the lowest pathway median gene BMC and (b) the 25th lowest rank-ordered gene BMC. ERα activation was evaluated using a published transcriptomic biomarker and an ERα-specific tPOD was derived. Genes fitting BMC models were subjected to upstream regulator and canonical pathway analysis in Ingenuity Pathway Analysis. Biomarker analysis identified BPA and eight alternative chemicals as ERα active. Global and ERα tPODs produced highly similar potency rankings with BPAF as the most potent chemical tested, followed by BPA, BPC, 4,4’-BPF, BPAP, BPS, BADGE, 2,4’-BPF, Pergafast201®, D-8, 2,4’-BPS, TGSA, and BPS-MAE. Further, BPA and transcriptionally active alternative chemicals enriched similar gene sets associated with increased cell division and cancer-related processes. These data provide support for future read-across applications of transcriptomic profiling for risk assessment of data-poor chemicals and suggest that several BPA alternative chemicals may cause hazards at similar concentrations to BPA.

Exposure to environmental chemicals alters human mammary gland morphogenesis and proteome

Project description:Environmental chemicals such as bisphenol A (BPA) are thought to contribute to carcinogenesis through their endocrine-disrupting effects. However BPA replacement chemicals are structurally similar, and little data exist describing their effects on the human body and environment. We established non-malignant human mammary organoid cultures to investigate the effects of BPA replacement chemicals on organoid morphology and protein abundance. At low-nanomolar doses, replacement chemicals, in particular BPS, induced branching and disrupted the organized mammary organoid architecture. BPS exposure likely alters mammary cell-type proportions and induces branching of predominately myoepithelial cells. Treatment with different replacement chemicals resulted in distinct proteomic changes. BPS exposure induced Cdc42-interacting protein 4 (CIP4), a protein known to support invadopodia formation and mesenchymal phenotypes. Our study provides evidence that replacement bisphenols have pro-tumorigenic effects on mammary morphology and the proteome, highlighting the necessity of comprehensive studies to evaluate the potential harm of replacement chemicals.

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.

Transcription profiling of C. elegans exposed to BPA, DEHP and NP - ecotoxicogenomic analysis

Project description:Gene expression analysis was conducted on the wildtype Caenorhabditis elegans exposed to bisphenol A (BPA), di(2-ethylhexyl) phthalate (DEHP) and nonylphenol (NP) using whole genome microarray. The microarray study was conducted in an ecotoxicological context, by investigating the response of global gene expression with that of classical toxicological endpoints, such as, mortality, growth, reproduction and development. Results provide insight into global transcription response of C.elegans to these endocrine disrupting chemicals exposure and also contribute to enhance the potential of C.elegans microarray in ecotoxicology (ecotoxicogenomics). key word : ecotoxicogenomics Experiment Overall Design: Young adults of wildtype C.elegans from age-synchronized population were exposed to NP, DEHP and BPA at the concentrations equivalent to 1/100 of 24h LC50 of each chemical, for 24 h and RNA extraction and hybridization were subsequently conducted using C.elegans Genome array (Affymetrix).

Toxicogenomic analysis of the effects of BDE-47/209, TBBPA/S, TCBPA on early neural development, with human embryonic stem cells

Project description:Flame retardants are detected globally in the environment, and pose great risks to human health. The potential effects of these chemicals on the development of nervous system have raise public concerns. In this study, to explore the toxicity profiles of these chemicals in the early developmental stage of human nervous system, we induced neural ectoderm from human embryonic stem cells in the presence of individual or mixture of BDE-47, BDE-209, TBBPA, TBBPS, TCBPA. By analyzing the whole transcriptional changes in the samples treated with 1 μΜ of each chemical, we identified a set of neural development relative biological processes that response to these chemicals. Genes involved in the GO terms relative to neural development were further confirmed by qRT-PCR assay, with samples treated with various concentrations (10 nM, 100 nM, 1 μΜ, 5 μΜ) of these chemicals. We found out that axon guidance and synaptogenesis may be the major target of these chemicals. In addition, these flame retardants may dysregulate the WNT and AHR signaling pathways. BDE-209 showed similar toxicity with BDE-47, whereas TBBPS and TCBPA may not be safe alternatives to TBBPA.
