Summary: BPA, a common component of plastics worldwide, has been shown to act as an endocrine disruptor with some hormonal functions. High levels of BPA are related to cardiovascular events and carcinogenesis pathways, and CKD patients have higher serum concentrations of BPA due to impaired renal function. Efforts to reduce BPA levels in these patients include developing BPA-free dialysis filters and other techniques.

Summary: The study reports the dual action of bisphenol compounds on ER alpha and ER beta receptors, with the bisphenol E analogs exhibiting enhanced agonist/antagonist activities due to an electrostatic halogen bond. Bisphenol C (BPC) is found to be a bifunctional ER alpha-agonist and ER beta-antagonist, with high ER alpha activity and inhibitory activity against ER beta. The intensified receptor interaction of BPC is attributed to the presence of an n-pi-pi-n conjugation system mediated through the >C = CCl2 double bond.

Summary: Diabetes, affecting nearly half a billion people worldwide, is linked to dysfunction of beta-cells. Exposure to endocrine-disrupting chemicals, such as bisphenol A (BPA), has been correlated with increased diabetes incidence. This study explores the activation of unfolded protein response (UPR) pathways in beta-cells under BPA treatment and the potential recovery of endoplasmic reticulum (ER) homeostasis. The findings suggest that modulators of UPR, like the chemical chaperone TUDCA, could be used as therapeutic interventions to restore beta-cell function.

Summary: This study reviewed the research on bacterial degradation of bisphenol analogues, finding that bacteria can degrade bisphenol analogues, especially bisphenol A. Sphingomonas, Sphingobium, and Cupriavidus are common degradation strains. The research is important for selecting suitable microorganisms for the bioremediation of bisphenol analogue pollution.

Summary: The study found that BPB and BPAF, analogs of BPA, have adverse effects on uterine health, causing endometrial contraction, decreased epithelial height, and increased gland numbers. Bioinformatics analysis revealed that both BPB and BPAF disrupt the immune landscape of the uterus. Furthermore, eight genes associated with BPB and BPAF exposure were found to be related to uterine corpus endometrial carcinoma (UCEC), and high expression of Srd5a1 was significantly correlated with poor prognosis in patients.

Summary: BPA and its analogues are widely used in plastic synthesis, potentially disrupting the hormonal structure of living organisms. Reports on BPA levels in air are limited, mainly due to anthropogenic activities. China reported the highest outdoor air levels of BPA near a low-tech e-waste recycling site, and indoor dust also revealed bisphenol analogues used in BPA-free products.

Summary: The study shows that both bisphenol A and its alternative bisphenol S can cause endocrine disrupting and genotoxic effects in brown trout, indicating two different mechanisms of damage underlying the activities of bisphenol A and bisphenol S. Bisphenol A primarily increases micronuclei frequency in fish erythrocytes, while bisphenol S may cause damage through other mechanisms.

Summary: Bisphenol A, a common endocrine disruptor found in daily products, is linked to obesity and diabetes due to its ability to mimic natural estrogen. This compound can stimulate adipocyte hypertrophy and alter the endocrine system. Despite some countries implementing policies, there is a lack of international agreement on the regulation of Bisphenol A exposure.

Summary: A robust method was developed to accurately and quickly detect bisphenol A and 13 analogs in soil. The method was applied to 29 soil samples from 21 provinces in China, revealing 12 bisphenols with notably high concentrations, particularly bisphenol P which was at least ten times higher than in other environmental matrices. The results indicate hot spots of bisphenol pollution in soil, calling for further investigations.

Summary: This study investigates the potential effects and mechanisms of bisphenol S (BPS) exposure on human colon mucosal epithelial cells. The results show that BPS exposure increases the production of pro-inflammatory cytokines, destroys the tight junctions of the cells, and affects neurotransmitters. These findings suggest that BPS exposure may disrupt the balance of the gut-brain axis, leading to inflammatory cytokine production and tight junction destruction.

Summary: Higher maternal bisphenol S urine concentrations, especially in the first trimester, seem to be associated with larger fetal head circumference, higher weight, and a lower risk of being small size for gestational age at birth. Other bisphenols were not consistently associated with fetal growth outcomes.

Summary: Bisphenol A (BPA), a common chemical used in plastic production, has emerged as a serious environmental concern due to its potential toxicity to plants. This study aimed to investigate the mechanism of BPA-induced root cells by examining the effects of BPA on the ultrastructure and function of soybean plant root tip cells. Changes in plant root cell tissues after BPA exposure were observed, and the accumulation of BPA in different plant parts was analyzed. The findings provide insight into how BPA can alter plant root growth.

Summary: In this study, metabolomics was used to investigate the metabolic response of sea cucumber exposed to BPAF, a type of bisphenol analogue. The results showed changes in lipid metabolism, glycerophospholipid metabolism, and amino acid synthesis following BPAF treatment. Sea cucumbers upregulated glycerophospholipid metabolism to repair intestinal cellular homeostasis destruction. Six metabolites were identified as potential biomarkers for BPAF exposure. This study provides theoretical support for assessing the risk of bisphenol analogues on economically important echinoderms such as A. japonicus.

Summary: The study investigated the effects of BPS and BPF on insulin secretion and ion channel activity in pancreatic beta-cells using WT and BERKO mice. Results showed that both compounds enhance insulin release by affecting ion channel activity, with the involvement of the ER beta pathway. Molecular dynamics simulations indicated differences in ER beta ligand-binding domain among different bisphenols and PaPE-1.

Summary: Cadmium (Cd) exposure in adulthood is associated with nonalcoholic fatty liver disease (NAFLD). This study reveals that developmental Cd exposure may also play a significant role in the programming of NAFLD. The Imprinted Gene Network (IGN) and its regulator Zac1 are identified as key factors in the programming of NAFLD during Cd exposure.

Summary: In this study, serum PFAS concentrations were determined for 31 dogs and 32 horses in Gray's Creek NC. PFAS were detected in every sample, with higher concentrations found in dogs compared to horses. The study suggests that long-term PFAS exposures may affect the renal and hepatic health of domestic animals.

This study evaluated the exposure of American alligators in the Cape Fear River to PFAS and found an association between increased PFAS exposure, disrupted immune functions, and autoimmune-like pathology in the alligator population.

Summary: PFAS are a class of synthetic organic chemicals that are chemically stable, persistent in the environment, and have been globally contaminating built and natural environments. Studies show that PFAS accumulate in the brain of humans and wildlife, potentially causing neurotoxic effects, especially with exposures during development. There is limited research on short-chain PFAS, and most studies focus on high dose exposures to single PFAS congeners rather than chronic low-dose mixtures, highlighting the need for further analysis on the neurodevelopmental effects of environmentally relevant concentrations and complex mixtures of PFAS.

Summary: The concept of key characteristics (KCs) has been developed to identify carcinogenic hazards and has now been applied to identify cardiovascular (CV) toxicants. This study identified 12 KCs of CV toxicants, divided into those affecting cardiac tissue, the vascular system, or both. These KCs can be used to identify potential CV toxicants and evaluate CV toxicity in a more comprehensive and standardized manner.
