Li H, Wang XR, Hu YF, Xiong YW, Zhu HL, Huang YC, Wang H. Advances in immunology of male reproductive toxicity induced by common environmental pollutants. ENVIRONMENT INTERNATIONAL 2024; 190:108898. [PMID: 39047547 DOI: 10.1016/j.envint.2024.108898] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 04/28/2024] [Revised: 06/25/2024] [Accepted: 07/18/2024] [Indexed: 07/27/2024]
Abstract
Humans are exposed to an ever-increasing number of environmental toxicants, some of which have gradually been identified as major risk factors for male reproductive health, even associated with male infertility. Male infertility is usually due to the reproductive system damage, which may be influenced by the exposure to contaminants such as heavy metals, plasticizers, along with genetics and lifestyle. Testicular immune microenvironment (TIM) is important in maintaining normal physiological functions of the testis, whether disturbed TIM after exposure to environmental toxicants could induce reproductive toxicity remains to be explored. Therefore, the current review aims to contribute to the further understanding of exposure and male infertility by characterizing environmental exposures and the effect on TIM. We first summarized the male reproductive toxicity phenotypes induced by common environmental pollutants. Contaminants including heavy metals and plastic additives and fine particulate matter (PM2.5), have been repetitively associated with male infertility, whereas emerging contaminants such as perfluoroalkyl substances and micro(nano)plastics have also been found to disrupt TIM and lead to male reproductive toxicity. We further reviewed the importance of TIM and its homeostasis in maintaining the normal physiological functions of the testis. Most importantly, we discussed the advances in immunology of male reproductive toxicity induced by metals and metalloids, plastic additives, persistent organic pollutants (POPs), micro(nano)plastic and PM2.5 to suggest the importance of reproductive immunotoxicology in the future study of environmental toxicants, but also contribute to the development of effective prevention and treatment strategies for mitigating adverse effects of environmental pollutants on human health.

JOURNAL OF HAZARDOUS MATERIALS 2024; 461:132597. [PMID: 37804762 DOI: 10.1016/j.jhazmat.2023.132597] [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: 07/04/2023] [Revised: 09/15/2023] [Accepted: 09/19/2023] [Indexed: 10/09/2023]
Abstract
Novel brominated flame retardants are widely used in electronics, textiles, furniture, and other products; they can enter the human body through ingestion and respiration and cause harm to the human body, and have been proven to have potential biological toxicity and accumulation effects. 1,2-bis(2,4,6-tribromophenoxy) ethane (BTBPE) is a widely used novel brominated flame retardant; however, there is a lack of research on its mechanism of toxicity, particularly that of intestinal toxicity. Currently, studies on the functionality of iroquois homeobox 3 (IRX3) are extremely limited. In our study, BTBPE was administered to Sprague-Dawley (SD) rats and rat small intestinal crypt epithelial cells (IEC6 cells) in vivo and in vitro, respectively, and hematoxylin and eosin (HE), immunohistochemical, Alcian blue-periodic acid-Schiff (AB-PAS), CCK8, acridine orange/ethidium bromide (AO/EB), fluorescent probes, qPCR, western blotting, and immunofluorescence analyses were performed. To explore the damage mechanism of BTBPE, we used siRNA to silence IRX3 and iNOs-IN-1 (yeast extract-peptone-wheat; YPW) to inhibit nitric oxide synthase 2 (NOS2). The results showed that BTBPE exposure caused inflammation and necroptosis in the jejunum and ileum, as well as destruction of the tight junctions and mucus layer. Moreover, BTBPE activated the IRX3/NOS2 axis both in vivo and in vitro. Silencing IRX3 or inhibiting NOS2 inhibits necroptosis and restores tight junctions in IEC6 cells. In conclusion, our study found that in the jejunum, ileum, and IEC6 cells, BTBPE exposure caused necroptosis and tight junction destruction by activating the IRX3/NOS2 axis. Blocking the IRX3/NOS2 axis can effectively inhibit necroptosis and restore tight junction. In addition, BTBPE exposure caused inflammation and loss of the mucous layer in the jejunum and ileum. Our study is the first to explore the mechanism of intestinal damage caused by BTBPE exposure and to discover new biological functions regulated by the IRX3/NOS2 axis, providing new research directions for necroptosis and tight junctions.

Abstract
Excessive alcohol consumption leads to serious liver injury. Necroptosis is a programmed cell death form, which has been confirmed to be involved in alcoholic liver injury. However, the exact mechanism remains still unclear. In this study, we found that ethanol caused hepatocytes necroptosis by activating receptor-interacting serine/threonine-protein kinase 1 and 3 (RIPK1 and RIPK3). Meanwhile, autophagy was activated in ethanol-treated hepatocytes. Accumulative studies have demonstrated a possible link between autophagy and necroptosis. Microtubule-associated protein 1 light chain 3 (LC3), an autophagy marker protein, is essential for autophagosome biogenesis/maturation. But little attention has been paid to its functional role. In this study, we explored whether LC3 was involved in ethanol-induced necroptosis. The data showed that LC3 interacted with RIPK1 and RIPK3 in ethanol-treated AML12 cells and mice liver by co-immunoprecipitation (co-IP) and colocalization assay. Ethanol-induced necrosome formation and subsequent necroptosis were alleviated in hepatocytes by knockdown of LC3 or autophagy inhibitor 3-methyladenine (3-MA). These results demonstrated that LC3 accumulation facilitated the formation of necrosome by LC3-RIPK1 and LC3-RIPK3 interactions, eventually caused hepatocytes necroptosis after acute ethanol exposure. Our current research could potentially offer a new understanding of the intricate mechanisms involved in the development of acute alcoholic liver injury.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2023; 902:166074.

Abstract
Superfluous molybdenum (Mo) and cadmium (Cd) in the environment are detrimental to organisms through their accumulation. The NF-κB/TNF-α axis plays a vital part in regulating necroptosis and apoptosis. However, the impacts of Mo and/or Cd on myocardium injury in ducks and the function of NF-κB/TNF-α axis are not clear in the process. In this research, ducks exposed to different dosages of Mo and/or Cd were applied as the study object. The findings substantiated that the accumulation of Mo and/or Cd caused elements imbalance and necroptosis in myocardial tissue. As p-NF-κB/TNF-α expression up-regulated, RIPK1/RIPK3/p-MLKL expression significantly increased in all treatment groups, while the expression of c-caspase-8/3 markedly decreased. Moreover, apoptosis rate obviously decreased in Cd treated groups and clearly elevated in Mo group. Mitochondria-mediated apoptosis was activated by excessive Mo and inhibited by Mo + Cd, but Cd exposure alone had little effect on it. Collectively, our research confirmed that Mo and/or Cd evoked necroptosis via NF-κB/TNF-α axis, and decreased death receptor-mediated apoptosis in duck myocardium, the impacts of Mo and/or Cd on mitochondrial-mediated apoptosis were different. These results are significant for studying toxicology of Mo and/or Cd and preserving the ecosystem.

Abstract
This study aimed to determine the potential protective effects of chrysin (CHR) on experimental cadmium (Cd)-induced lung toxicity in rats. To this end, rats were divided into five groups; Control, CHR, Cd, Cd + CHR25, Cd + CHR50. In the study, rats were treated with CHR (oral gavage, 25 mg/kg and 50 mg/kg) 30 min after giving Cd (oral gavage, 25 mg/kg) for 7 consecutive days. The effects of Cd and CHR treatments on oxidative stress, inflammatory response, ER stress, apoptosis and tissue damage in rat lung tissues were determined by biochemical and histological methods. Our results revealed that CHR therapy for Cd-administered rats could significantly reduce MDA levels in lung tissue while significantly increasing the activity of antioxidant enzymes (SOD, CAT, GPx) and GSH levels. CHR agent exerted antiinflammatory effect by lowering elevated levels of NF-κB, IL-1β IL-6, TNF-α, RAGE and NRLP3 in Cd-induced lung tissue. Moreover CHR down-regulated Cd-induced ER stress markers (PERK, IRE1, ATF6, CHOP, and GRP78) and apoptosis markers (Caspase-3, Bax) lung tissue. CHR up-regulated the Bcl-2 gene, an anti-apoptotic marker. Besides, CHR attenuated the side effects caused by Cd by modulating histopathological changes such as hemorrhage, inflammatory cell infiltration, thickening of the alveolar wall and collagen increase. Immunohistochemically, NF-κB and Caspase-3 expressions were intense in the Cd group, while these expressions were decreased in the Cd + CHR groups. These results suggest that CHR exhibits protective effects against Cd-induced lung toxicity in rats by ameliorating oxidative stress, inflammation, apoptosis, endoplasmic reticulum stress and histological changes.

Abstract
The impacts of environmental PM 2.5 on public health have become a major concern all over the world. Many studies have shown that PM 2.5 still poses a threat to public health even at very low levels. Physical or chemical reactions occur between primary particles and other components in the environment, which changes the properties of primary particles. Such newly formed particles with changed properties are called secondary particles. Ozone-oxidized black carbon (oBC) is a key part of PM 2.5 and a representative secondary particle. Macrophages extracellular traps (METs) is a means for macrophages to capture and destroy invading pathogens, thereby exercising innate immunity. Necroptosis is a kind of programmed cell death, which is accompanied by the destruction of membrane integrity, thus inducing inflammatory reaction. However, there is no research on the crosstalk mechanism between necroptosis and MET after oBC exposure. In our study, AO/EB staining, SYTOX Green staining, fluorescent probe, qPCR, Western blot, and immunofluorescence were applied. This experiment found that under normal physiological conditions, when macrophages receive external stimuli (such as pathogens; in our experiment: phorbol 12-myristate 13-acetate (PMA)), they will form METs, capture and kill pathogens, thus exerting innate immune function. However, exposure to oBC can cause necroptosis in macrophages, accompanied by increased levels of reactive oxygen species (ROS) and cytosolic calcium ions, as well as the expression disorder of inflammatory factors and chemokines, and prevent the formation of METs, lose the function of capturing and killing pathogens, and weaken the innate immune function. Notably, inhibition of necroptosis restored the formation of METs, indicating that necroptosis inhibited the formation of METs. This study was the first to explore the crosstalk mechanism between necroptosis and METs after oBC exposure.

Notably, inhibition of necroptosis restored the formation of METs, indicating that necroptosis inhibits the formation of METs. Our experiment will enrich the understanding of the mechanism of macrophage injury caused by BC exposure, provide a new direction for studying harmful atmospheric particle toxicity, and propose new therapeutic insights for diseases caused by atmospheric particulate matter. This study is the first to explore the crosstalk mechanism between necroptosis and METs after BC exposure.

A Novel Defined PANoptosis-Related miRNA Signature for Predicting the Prognosis and Immune Characteristics in Clear Cell Renal Cell Carcinoma: A miRNA Signature for the Prognosis of ccRCC.

Abstract
Clear cell renal cell carcinoma (ccRCC) is one of the most prevalent cancers, and PANoptosis is a distinct, inflammatory-programmed cell death regulated by the PANoptosome. The essential regulators of cancer occurrence and progression are microRNAs (miRNAs). However, the potential function of PANoptosis-related microRNAs (PRMs) in ccRCC remains obscure. This study retrieved ccRCC samples from The Cancer Genome Atlas database and three Gene Expression Omnibus datasets. PRMs were recognized based on previous reports in the scientific literature. Regression analyses were used to identify the prognosis PRMs and construct a PANoptosis-related miRNA prognostic signature based on the risk score. We discovered that high-risk patients had poorer survival prognoses and were significantly linked to high-grade and advanced-stage tumors, using a variety of R software packages and web analysis tools. Furthermore, we demonstrated that the low-risk group had significant changes in their metabolic pathways. In contrast, the high-risk group was characterized by high immune cell infiltration, immune checkpoint expression, and low half-maximum inhibition concentration (IC50) values of chemotherapeutic agents. This suggests that high-risk patients may benefit more from immunotherapy and chemotherapy. In conclusion, we constructed a PANoptosis-related microRNA signature and revealed its potential significance in clinicopathological features and tumor immunity, thereby providing new precise treatment strategies.

Abstract
1,4-Naphthoquinone-coated BC (1,4 NQ-BC) is an important component of PM2.5 and a representative secondary particle. However, there is no research on the crosstalk mechanism between necroptosis and macrophage extracellular traps (METs) after 1,4 NQ-BC exposure. In this study, we treated RAW264.7 cells with 50, 100, and 200 mg/L 1,4 NQ-BC for 24 h, with 10 μM necrostatin-1 for 24 h, and with 2.5 μM phorbol 12-myristate 13-acetate (PMA) for 3 h. Our experiment revealed that under normal physiological conditions, when macrophages receive external stimuli (such as pathogens; in this experiment, PMA), they will form METs and capture and kill pathogens, thus exerting innate immune function. However, exposure to 1,4 NQ-BC can cause necroptosis in macrophages, accompanied by increased levels of reactive oxygen species (ROS) and cytosolic calcium ions, as well as the expression disorder of inflammatory factors and chemokines, prevent the formation of METs, lead to loss of the function of capturing and killing pathogens, and weaken the innate immune function. Notably, inhibition of necroptosis restored the formation of METs, indicating that necroptosis inhibited the formation of METs. Our study was the first to explore the crosstalk mechanism between necroptosis and METs. This experiment will enrich the mechanism of macrophage injury caused by 1,4 NQ-BC exposure.

Abstract
Di-(2-Ethylhexyl) phthalate (DEHP) and microplastics (MPs) have released widespread residues to the environment and possess the ability to cause damage to humans and animals. However, there are still gaps in the study of damage to neurons caused by DEHP and MPs in mice cerebra and whether they have combined toxic effects. To investigate the underlying mechanism of action, mice were fed 200 mg/kg DEHP and 10 mg/L MPs in vivo. In vitro, NS20Y (CBNumber: CB15474825) cells were treated with 25 μM DEHP and 775 mg/L MPs. Next, qRT-PCR and western blot analysis were performed to evaluate PI3K/AKT pathway genes, mitochondrial dynamics-related genes, apoptosis-related genes, and GSK-3β and its associated genes, mRNA, and protein expression. To determine pathological changes in the mice cerebra, hematoxylin and eosin (H&E) staining, transmission electron microscopy, and TUNEL staining were employed. To determine the levels of reactive oxygen species (ROS) and apoptosis cells in vitro, ROS staining, acridine orange/ethidium bromide (AO/EB) staining, and flow cytometry were performed. Our results demonstrated that DEHP and MPs caused changes in mitochondrial function, and GSK-3β and its associated gene expression in mice through the PI3K/AKT pathway, which eventually led to apoptosis of neurons. Moreover, our findings showed that DEHP and MPs have a combined toxic effect on mice cerebra. Our findings facilitate the understanding of the neurotoxic effects of DEHP and MPs on neurons in the cerebra of mice and help identify the important role of maintaining normal mitochondrial function in protecting cerebrum health.
