Summary: This study demonstrates that co-exposure to BPA and gamma-ray in mice can induce DNA damage in fetal germ cells, leading to a decrease in germ cell abundance and impact testicular function. Additionally, exposure to gamma-ray alone significantly alters adult steroidogenesis, affecting courtship behavior. The findings highlight the importance of considering physical agents as endocrine disruptors and the need for reevaluation of risk management and regulatory decisions.

Summary: Bisphenol A (BPA), an endocrine disrupting chemical (EDC), is believed to be involved in the pathogenesis of various diseases, including immune-mediated disorders, type-2 diabetes mellitus, cardiovascular diseases, and cancer. This review aims to analyze the mechanism of action of BPA, with a specific focus on mesenchymal stromal/stem cells (MSCs) and adipogenesis. The uses of BPA in dental, orthopedic, and industrial fields will be assessed, as well as the impact on different pathological or physiological conditions and related molecular pathways.

Summary: The aim of this study was to determine the toxicity of bisphenol A (BPA) and its derivatives on various organisms. The results showed that BPA, BPS, and BPF exhibited high toxicity on bacteria, reaching concentrations of 0.018-0.031 mg/L. These compounds also showed genotoxicity and cytotoxicity effects on human cells, as well as phytotoxicity effects on plants. The findings suggest that BPA and its derivatives have a negative impact on living organisms through apoptosis and genotoxic mechanisms.

Summary: This study investigated the impact of a probiotic mixture on BPA-induced effects on reproduction in zebrafish. The results demonstrated that in fish exposed to the combination of BPA and probiotic, most transcripts were closer to control or probiotic-treated levels, suggesting the potential of the probiotic mixture to counteract BPA toxicity.

Summary: This study aimed to investigate the impact of intrauterine exposure to DEHP on the hypothalamic-pituitary-thyroid (HPT) axis function programming of the offspring animals during adulthood. The results showed that DEHP exposure decreased TSH levels and reduced the gene expression and protein content of thyroid-related genes in female offspring rats. In male offspring rats, DEHP exposure increased TSH expression and levels. These findings suggest that DEHP exposure disrupts the HPT axis function and increases the susceptibility of the offspring animals to develop thyroid dysfunctions during adulthood.

Summary: Ovarian cells have the ability to metabolize bisphenols, such as BPA and BPS, into their respective sulfo-conjugates, with sulfation being the main metabolic route. The persistence of BPA residues is higher than that of BPS in theca cells, and only theca explants can deconjugate inactive BPA-glucuronide and BPS-glucuronide back into their biologically active forms. These findings raise concerns about the direct release of bisphenols in the ovary and highlight the importance of studying the biotransformation of bisphenols in different ovarian cells for risk assessment.

Summary: Puberty is a complex process that involves a delicate balance of neuroendocrine mechanisms and hormones to achieve psychophysical maturity and reproductive capacity. The onset of puberty is triggered by interactions between the hypothalamus, pituitary gland, and gonads, with significant variations between genders and individuals, as well as possible pathological variations such as precocious and delayed puberty.

Summary: This study in the adult Korean population found that the direction of associations between exposure to phthalates, BPA, and parabens and obesity and diabetes mellitus varied depending on the method used to adjust urinary dilution. It highlights the importance of choosing an appropriate adjustment method when studying the associations between these chemical exposures and health outcomes. Further research in other populations is needed to confirm these findings.

Summary: The neuroendocrine control of reproduction is regulated by the pulsatile release of GnRH by hypothalamic neurons. BaP, a pollutant, can disrupt endocrine function and affect gonadal function and gamete maturation. This study found that BaP alters the phenotype and function of GnRH neurons by interfering with KISS1R signaling and GnRH secretion, highlighting its importance in the central neuroendocrine control of reproduction.

Summary: Bisphenol A (BPA) and phthalates, as endocrine-disrupting chemicals, are widely distributed in the environment and can affect cellular proliferation, tissue development, and various physiological processes through interference with hormone synthesis and action. Exposure to these compounds is inevitable and unintentional for humans and living organisms, potentially leading to a wide range of chronic diseases later in life. Monitoring of EDC levels and their impact on human health is crucial for the general population and the healthcare system.

Summary: The majority of human embryo culture media assessed contained bisphenol S, while no release of bisphenols by plastic consumables was detected under routine conditions. Further studies are needed to investigate a greater number of ART media to identify less potentially harmful ones in terms of bisphenol content.

Summary: This study analyzed the effects of BPA and BPS on steroidogenesis in ovine granulosa cells in vitro and compared the effects of GPER agonist and antagonist. The results showed that both BPA and BPS affected progesterone secretion, while only BPS affected estradiol secretion. RNA-seq analysis revealed that BPA mainly disrupted the expression of genes involved in metabolism and transcription, while BPS mainly impaired cellular communication. These findings are important for further investigations on the temporal changes of these genes and the biological processes involved.

Summary: Estrogens play a role in promoting the function of cholinergic neurons and have an impact on cognitive function. This study found that ovariectomy reduces the expression of cholinergic synaptic proteins in the entorhinal cortex, and this reduction can be prevented by estradiol replacement. Ovariectomy also impairs the cholinergic modulation of excitatory transmission in the entorhinal cortex, which may be related to the changes in cholinergic proteins.

Summary: Bilirubin is a byproduct of heme metabolism, and Ugt1a1 is the enzyme responsible for its elimination. Dysfunctional Ugt1a1 can lead to the accumulation of unconjugated bilirubin in the brain, causing neuronal damage and death. Understanding alternative bilirubin detoxification mechanisms is crucial for developing new therapeutic strategies. Activation of alternative clearance pathways can partially improve hyperbilirubinemic conditions in the absence of Ugt1a1.

Summary: Increasing evidence suggests that mitochondrial dysfunction and aberrant release of mitochondrial reactive oxygen species (ROS) play crucial roles in early synaptic perturbations and neuropathology that drive memory deficits in Alzheimer's disease (AD). Solubilized human amyloid beta peptide 1-42 (hA beta(1-42)) causes rapid alterations at glutamatergic synapses in the entorhinal cortex (EC) through the activation of both GluN2A- and GluN2B-containing NMDA receptors. This study reveals that hA beta(1-42) disrupts mitochondrial respiratory functions and increases ROS in the entorhinal cortex, leading to synaptic dysfunctions that may contribute to early AD-related neuropathology.
