... Bisphenol A (BPA) has been shown to induce liver fibrosis in rodents. Therefore, this study examined the protective effect of a triple combination of curcumin (Cur), N-acetyl cysteine (NAC) and propolis (Prp) extract against BPA-induced hepatic fibrosis.100 Wistar male rats were equally assigned into 10 groups; one group was designated as control. 10 rats were gavaged with BPA (50 mg/kg/day) for 8 ...
... Bisphenol A (BPA) (2,2,-bis (hydroxyphenyl) propane), a well-known endocrine disruptor (ED), is the exogenous chemical that mimic the natural endogenous hormone like oestrogen. Due to its extensive exposure to humans, BPA is considered to be a major toxicological agent for general population. Environmental exposure of BPA results in adverse health outcomes including bone loss. BPA disturbs the bon ...
... The frequency of estrogen receptor alpha (ERα)-positive breast cancers and their metastatic progression is prevalent in females globally. Aberrant interaction of estrogen-like endocrine-disrupting chemicals (EDCs) is highly implicated in breast carcinogenesis. Studies have shown that single or acute exposures of weak EDCs such as bisphenol A (BPA) may not have a substantial pro-carcinogenic/metast ...

Abstract:
... AIMS: Bisphenol A (BPA), a major component of epoxy resins used in protective coatings, is a known endocrine-disrupting chemical. BPA has the ability of binding to estrogen receptors. In the current paper, we examine the direct effects of bisphenol A on in vitro osteoclast and osteoblast culture systems. MAIN METHODS: We evaluated the effects of BPA on osteoclast formation using bone marrow-derive ...
... Bisphenol A (BPA) can act as pathogenic agent on mammalian cells. However, whether BPA induces colonic epithelial cell damage remains unexplored. We used HCT116 cells as a model to investigate the negative effect of BPA on human colon cancer cells and explore the potential mechanism. Our results suggest that BPA decreased viability of HCT116 cells. BPA also caused serious oxidative damage to the c ...
... Nowadays, endocrine disrupting chemical pollution has become one of the major concerns due to the potential role of these chemicals in provoking endocrine disorders especially type 2 diabetes. As a widespread endocrine disrupting chemical, Bisphenol A, with modest estrogenic activity can exert its detrimental effects in the different organs involved in type 2 diabetes such as pancreas, liver, adip ...
... Mesenchymal stem cells (MSCs) are found in all adult mesenchymal tissues. They play a role in the maintenance of tissue homeostasis and repair by allowing renewal of the cellular stock. MSCs can be isolated from both human and animal sources. These cells are important in regenerative medicine and cell therapy, thus adipose tissue is a rich and promising source of these cells. Adipose-derived stem ...

... Bisphenol (BP)-A exposure can impair glucose and lipid metabolism. However, it is unclear whether this endocrine disruptor (ED) modulates these processes in postmenopause, a period with organic changes that increase the risk for metabolic diseases. Herein, we evaluated the effects of BPA exposure on adiposity, glucose homeostasis and hepatic steatosis in ovariectomized (OVX) mice fed on a high-fat ...
... Bisphenol A (BPA), an endocrine disruptor used in industrial applications, has been detected in both placenta and milk. We studied the effects of BPA exposure during pregnancy and lactation on body composition, palatable food intake, biochemical, hormonal and behavioral profiles of young and adult Wistar rat offspring.Female rats were divided into: control, BPA10 (10 μg/kg/day) and BPA50 (50 μg/kg ...
... Phytoestrogens and xenoestrogens act as agonists/antagonists in bone formation and differentiation. Strong bones are depending of the ability of osteoblasts to form new tissue and to mineralize the newly formed tissue. Dysfunctional or loss of mineralization leads to weak bone and increased fracture risk. In this study, we reported the effect of different types of phytoestrogens (daidzein, geniste ...
... Obesogens are a type of endocrine-disrupting chemicals (EDCs) that disrupt the human endocrine system, resulting in obesity and metabolic disease. Several obesogens, including bisphenol A, tolylfluanid, and some pesticides, have been identified and studied previously; however, the underlying molecular mechanisms by which obesogens interfere with adipogenesis and induce insulin resistance in adipoc ...
... Fluorene-9-bisphenol (BHPF), as a substitute for bisphenol A, is used in many industries in daily life. Many studies have clarified its effects as an endocrine disruptor on organisms, but its effect on lipid metabolism of zebrafish larvae is not clear. Patients with non-alcoholic fatty liver disease (NAFLD) are more susceptible to external pollutants. It is not clear how BHPF perturbs lipid metabo ...
... Hormone receptors are the main markers applied for prognosis of breast cancer subtypes. Among modulators, exogenous chemical agents known as endocrine disruptors interact with certain receptors, triggering molecular pathways or increasing their expression. Bisphenol A (BPA), a xenoestrogen, interacts with several hormone receptors. Thus, our aim was to characterize the hormone receptor status in t ...
... Methylsulfonylmethane (MSM), is an organosulfur compound, has many health benefits. Bisphenol-A (BPA) and γ-radiation (R) are two risky environmental contaminants that human beings are exposed to in everyday life. This work aims at unveiling the modulatory role of MSM in combating BPA and R co-exposure induced neurodegenerative disorder (Alzheimer's (AD)-mimic neurotoxicity).Female rats were rando ...

Abstract:
... Endocrine disruption due to environmental chemical contaminants is a global human health issue. The aim of present study was to investigate the structural binding aspects of possible interference of commonly detected environmental contaminants on thyroid function.Three compounds, 4-tert-octylphenol (4-tert-OP), 4-nonylphenol (4-NP), and 4-methyl-2,4-bis(4-hydroxypentyl)pent-1-ene (MBP) were subjec ...
... Environmental pollutants such as plastic-component substances (phthalates and bisphenol A) that coexist in natural ecosystems have been linked to an increase in the occurrence of human health hazards, particularly cardiovascular health. This study was designed to investigate single and combined cardio-toxic effects of dibutyl phthalate and bisphenol-A and the possible interventional role of rutin. ...
... Bisphenol A, one of the industrial chemicals used in plastics and in the coating of dishes and medical equipment, behaves as an endocrine disruptor in the human body. Bisphenol A can bind directly to several types of nuclear receptors, including steroid and xenobiotic receptor (SXR). SXR plays an important role in bone metabolism through the activation of osteoblasts in vitro, but SXR protein loca ...
