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.

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

Project description:Estrogen receptor alpha (ERα) is a ligand dependent transcription regulator, which contains two transactivation functional domains, AF-1 and AF-2. These activities are regulated differently by the ligands. Specifically, the selective estrogen receptor modulators (SERMs) regulate AF-1 rather than AF-2. It is important to know whether AF-1/AF-2 predominantly regulated genes exist in the tissues for a better understanding of the SERMs functionality. We sought out AF-1 dependent estrogenic genes by using the AF-2 mutated knock-in (KI) mouse model, AF2ERKI. AF2ER is an estrogen-insensitive AF-2 disrupted ERα mutant mouse but unique to this model, AF-1 can be activated by the estrogen-antagonist, fulvestrant (ICI), in vitro and in vivo. The information of ICI-mediated gene expression profile of AF2ERKI could define whether AF-1/AF-2 predominantly regulated genes exist in the tissues.

Project description:Purpose:Our goal was to identify and characterize a new molecular target of Bisphenol A（BPA）in uterine leiomyoma cells to better understand how this compound may affect uterine leiomyomas growth and development. Methods: Primary cultured cell lines of uterine leiomyoma were treated with 0.1% DMSO or 10.0 μmol/L BPA for 48 h before RNA-seq and histone 3 lysine 27 acetylation (H3K27ac) ChIP-seq were performed. Integrative analysis of ChIP-seq and RNA-seq data identifies the key transcription factor (TF)，target gene and signaling pathway. To confirm the expression level of TF and target gene in uterine leiomyomas tissues, we analyzed 10 human uterine leiomyoma tissues and the matched adjacent uterine smooth muscle tissues using western blotting, and 96 paired paraffin-embedded human uterine samples by immunohistochemistry(IHC). The ChIP assay used to confirm the combination between the TF and target gene. In order to verify the functions of key TF, lentivirus was used to knock down the expression level and detect the effects on cell proliferation, cell cycle, and cell tumorigenicity. We further conducted Western blot analysis to confirm the whether the downstream signaling pathway is activated. RESULTS: Integrative Analysis of ChIP-seq and RNA-seq data identifies the key transcription factor XBP1and target gene ITGA2. The qPCR and ChIP- qPCR initially verified the sequencing results. XBP1 and ITGA2 were overexpressed in human uterine leiomyoma tissues. The IHC results confirmed that ITGA2 was significantly correlated with XBP1 expression (R = 0.6708, P < 0.001)， and the ChIP assay showed that XBP1 binds to the the ITGA2 predicted promoter region. BPA promoted uterine leiomyoma cells proliferation both in vitro and in vivo and that XBP1 expression levels modulated the cellular response to this endocrine disruptor. BPA upregulated ITGA2 through XBP1 and activated the downstream PI3K-AKT signaling pathway to promote the proliferation of human uterine leiomyoma cells. CONCLUSION: In conclusion, our current work reveals a novel mechanism by which BPA promotes the proliferation in uterine leiomyoma cells. The XBP1 transcription factor regulates and activates the downstream ITGA2/PI3K/AKT pathway. By defining XBP1 as an important regulatory role of BPA in uterine leiomyoma cell proliferation, they provide new insights into the pathogenesis related to the exposure to BPA and other endocrine disruptors acting similarly, and XBP1 may serve as a candidate molecular target for intervention and treatment of uterine leiomyomas.

Project description:Bisphenol A (BPA), widely used in plastics and resins, raised health concerns for its endocrine-disrupting effects. BPA analogues like bisphenol S (BPS) and bisphenol F (BPF) emerged as alternatives but were found to exhibit similar risks. Despite many countries have implemented BPA regulations, alternatives remain insufficiently regulated Although the safety of BPS and BPF has not been sufficiently verified, they have already been detected in various surrounding environments and human urine, raising serious concerns Bisphenols are expected to have various adverse effects, but research on this is lacking. This study explores the adverse effects of bisphenol mixtures on rats from fetus to young adulthood, analyzing transcriptomes by tissue and gender to identify key genes impacted by bisphenol exposure. Dams were orally administered test substances from gestational day 6 to lactation day 6. F1 pups received the same substances at half the concentration from postnatal day 7 to day 63. The tissues collected from the pups were subjected to transcriptome analysis, and core genes were identified through integrated analysis. The study identifies core genes associated with high-density lipoprotein and hormone secretion. These genes provide insights into the mechanisms through which BPA may cause hormonal imbalances. Furthermore, the study suggests that a complex exposure of BPA, BPS, and BPF can exerts different effects than BPA alone, pronounced effects on the thyroid and reproductive organs, even though individual concentrations were below the no-observed-adverse-effect-level. It highlights the potential cumulative impact of endocrine disrupting chemicals in the body.
