[PMID: 38309369 DOI: 10.1016/j.scitotenv.2024.170543] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 11/24/2023] [Revised: 01/26/2024] [Accepted: 01/27/2024] [Indexed: 02/05/2024]
Abstract
Polychlorinated biphenyls (PCBs) are a class of endocrine-disrupting chemicals (EDCs) widely present in the environment. PCBs have been of concern due to their anti/estrogen-like effects, which make them more toxic to the female reproductive system. However, there is still a lack of systematic reviews on the reproductive toxicity of PCBs in females, so the adverse effects and mechanisms of PCBs on the female reproductive system were summarized in this paper. Our findings showed that PCBs are positively associated with lower pregnancy rate, hormone disruption, miscarriage and various reproductive diseases in women. In animal experiments, PCBs can damage the structure and function of the ovaries, uterus and oviducts. Also, PCBs could produce epigenetic effects and be transferred to the offspring through the maternal placenta, causing development retardation, malformation and death of embryos, and damage to organs of multiple generations. Furthermore, the mechanisms of PCBs-induced female reproductive toxicity mainly include receptor-mediated hormone disorders, oxidative stress, apoptosis, autophagy, and epigenetic modifications. Finally, we also present some directions for future research on the reproductive toxicity of PCBs. This detailed information provided a valuable reference for fully understanding the reproductive toxicity of PCBs.

Abstract
Polychlorinated biphenyls (PCBs) are a group of highly toxic endocrine-disrupting chemicals comprising 209 homologs. PCBs are extensively found in the environment and can induce typical estrogenic and profound, long-lasting effects on animals. In this article, the introduction of PCB residues into the environment and the pathways of PCB enrichment in animals are described. PCBs are widely deposited and eventually accumulate in human tissues and body fluids through biomagnification. PCBs can significantly decrease animal fertility and interfere with endocrine processes, leading to the development of various diseases and even cancer. The effects of PCBs on the reproductive systems of animals can also be passed to their offspring, indicating that PCBs may affect the epigenetic modification process. There is currently no treatment to effectively inhibit the toxicity of PCBs in organisms; therefore, the severity of PCB toxicity needs to be widely recognized.

Effects of 2,3',4,4'5-pentachlorobiphenyl exposure during pregnancy on epigenetic imprinting and maturation of offspring's oocytes in mice. Arch Toxicol 2019; 93:2575-2592. [PMID: 31388691 DOI: 10.1007/s00204-019-02529-z] [Citation(s) in RCA: 14] [Impact Index Per Article: 2.8] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/29/2019] [Accepted: 07/29/2019] [Indexed: 12/21/2022]
Abstract
Polychlorinated biphenyls (PCBs) are a class of organic pollutants that have been widely found in the environment. The chemical 2,3',4,4'5-pentachlorobiphenyl (PCB118) is an important dioxin-like PCB compound with strong toxicity. PCB118 can accumulate in adipose tissue, serum and milk in mammals, and it is highly enriched in the follicular fluid. In this study, pregnant mice were exposed to 0, 20 and 100 μg/kg/day of PCB118 during pregnancy at the fetal primordial germ cell migration stage. The methylation patterns of the imprinted genes H19, Snrpn, Peg3 and Igf2r as well as the expression levels of Dnmt1, 3a, 3b and 3l, Uhrf1, Tet2 and Tet3 in fully grown germinal vesicle oocytes were measured in offspring. The rates of in vitro maturation, in vitro fertilization, oocyte spindle and chromosomal abnormalities were also calculated. The results showed that prenatal exposure to PCB118 altered the DNA methylation status of differentially methylated regions in some imprinted genes, and the expression levels of Dnmt1, 3a, and 3l, Uhrf1 and Tet3 were also changed. In addition, PCB118 disturbed the maturation process of progeny mouse oocytes in a dose-dependent manner. Therefore, attention should be paid to the potential impacts of PCB118-contaminated dietary intake during pregnancy on the offspring's reproductive health.

Abstract
3,3',4,4',5-Polychlorinated biphenyl (PCB126) is a persistent organic environmental pollutant which can affect various biological activities of organisms, such as immunity, neurological function, and reproduction. In our study, we aimed to investigate the effects of PCB126 on granulosa cells (GCs). GCs were collected from ovaries in PMSG-treated mice, after 24 hours culture. GCs were then incubated with 10 pg/mL, 100 pg/mL, and 10 ng/mL of PCB126 for another 24 hours. Following these steps, exposed GCs were collected for further experimentation. Our data showed that the number of GCs in the 10 ng/mL PCB126 decreased. Meanwhile, pyknotic nuclei and condensed chromatin increased, while the apoptotic cells in the 10 ng/mL PCB126 group were significantly increased. Furthermore, the expression of the apoptotic executive protein caspase-3 increased after PCB126 treatment. The expression of Bax, Bcl-2, and Bim related to the mitochondrial apoptosis pathway were also influenced to different degrees. Thus, our data suggested that PCB126 affect the GCs apoptosis, and mitochondrial apoptosis pathway was involved in this process.

Abstract
Persistent organic pollutants (POPs) are ubiquitously distributed among the U.S. population and adversely impact human reproduction. These compounds have been detected in human ovarian follicular fluid (FF), where they directly contact a developing oocyte. As a pilot investigation, we measured 43 polychlorinated biphenyl (PCB) congeners, p,p'-dichlorodiphenyltrichloroethane (DDT), and its persistent metabolite p,p'-dichlorodiphenyldichloroethylene (DDE) in residual FF collected from 32 women undergoing in vitro fertilization (IVF). We identified significant inverse associations between higher levels of PCB congeners and indicators of ovarian reserve (e.g., antral follicle count), follicular response to administered gonadotropins (e.g., peak estradiol, number of oocytes retrieved, endometrial thickness), intermediate IVF endpoints (e.g., oocyte fertilization and embryo quality), and clinical IVF outcomes (e.g., embryo implantation and live birth), after adjusting for body mass index, cigarette smoking, race, and age. Our results suggest that ongoing exposure to POPs impacts IVF and merit confirmation in a larger and more definitive future study.

Abstract
Graphene oxide (GO), owing to its large surface area and abundance of oxygen-containing functional groups, is emerging as a potential adsorbent for polychlorinated biphenyls (PCBs), which accumulate over time and are harmful to both natural ecosystems and human health. However, the effect of GO against PCB-induced toxicity remains largely unexplored. The present study aimed to investigate the protective effect of GO against PCB 52 induced cytotoxic and genotoxic response in mammalian cells at various exposure conditions and clarify the protective role of autophagy. Pretreatment with GO dramatically decreased PCB 52 induced cytotoxicity and CD59 gene mutation in human-hamster hybrid (AL) cells. The toxic response in cells either pretreated with PCB 52 and then treated with GO or concurrently treated with GO and PCB 52 did not differ significantly from the toxic response in the cells treated with PCB 52 alone. Using autophagy inhibitors (3-methyladenine and wortmannin) and inducers (trehalose and rapamycin), we found that genuine autophagy induced by GO was involved in decreasing PCB 52 induced toxicity. These findings suggested that GO has an antagonistic effect against the toxicity of PCB 52 mainly by triggering a genuine autophagic process, which might provide new insights into the potential application of GO in PCB disposal and environmental and health risk assessment.
