JOURNAL OF HAZARDOUS MATERIALS 2024; 485:136924. [PMID: 39709808 DOI: 10.1016/j.jhazmat.2024.136924] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/28/2024] [Revised: 12/03/2024] [Accepted: 12/15/2024] [Indexed: 12/24/2024]
Abstract
In this study, a mixed model was applied to the marine medaka to investigate the intergenerational effects of parental exposure to Triphenyltin (TPT) and the subsequent perturbations in parental gut microbiota on the gut microbiota of offspring. In addition, "microgenderome" has been focused on elucidating the different responses of males and females to environmental stress. The results indicated that TPT exhibited androgenic effects and long-term toxicological consequences, influencing the internal steroid hormone levels of the offspring and leading to their abnormal growth and development. Furthermore, the "microgenderome" has been observed in fish, which resulted in sex-specific responses among females and males when exposed to TPT. The effects of parental TPT exposure on offspring also varied by sex; specifically, it disrupted the intestinal microenvironment in female offspring, creating selective pressure on gut microbiota. In contrast, the male gut microbiota exhibited greater sensitivity to environmental perturbations, allowing rapid community interactions to achieve a relatively stable state. These findings suggest that TPT poses significant long-term toxicological effects that warrant further attention and management. Moreover, the identification of the "microgenderome" phenomenon in fish may provide new insights into gut microbiota disruption and its functional implications.

Multigenerational effects of combined exposure of triphenyltin and micro/nanoplastics on marine medaka (Oryzias melastigma): From molecular levels to behavioral response. JOURNAL OF HAZARDOUS MATERIALS 2024; 480:136365. [PMID: 39488982 DOI: 10.1016/j.jhazmat.2024.136365] [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: 08/27/2024] [Revised: 10/26/2024] [Accepted: 10/29/2024] [Indexed: 11/05/2024]
Abstract
In natural environments, micro/nanoplastics (MNP) inevitably coexist with various pollutants, making it essential to examine their combined toxicity and intergenerational effects on marine organisms. This study investigated the combined toxicity and intergenerational effects of exposure to triphenyltin (T), microplastics (M), nanoplastics (N), a combination of microplastics and triphenyltin (MT), and a combination of nanoplastics and triphenyltin (NT) on marine medaka. The results showed that all treatments had adverse and intergenerational effects on marine medaka. Regarding oxidative stress and energy metabolism, smaller sized plastic particles caused more significant damage to the organisms. However, MT inflicted greater gonadal system damage than NT, leading to imbalanced sex hormone levels. Additionally, T induced hyperactivity in fish, whereas MNP tended to induce behavioral depression. Notably, large plastic particles in the F0 generation had a more pronounced impact on depressive behaviors compared to smaller particles. These findings suggest that both individual and combined exposures to TPT and MNP can detrimentally affect marine medaka from the molecular to behavioral levels, posing risks to population sustainability. This study provided a robust theoretical foundation and deeper insights into the ecotoxicological impacts and risk assessments of coexisting pollutants.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2024; 954:176214. [PMID: 39299340 DOI: 10.1016/j.scitotenv.2024.176214] [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: 06/25/2024] [Revised: 09/08/2024] [Accepted: 09/09/2024] [Indexed: 09/22/2024]
Abstract
Human exposure to organotin is common but little is known about the adverse pregnancy outcomes. This study aimed to explore the association between organotin exposure and the risk of non-syndromic cleft lip with or without cleft palate (NSCL/P) and to explore the underlying mechanism. Placental samples (109 NSCL/P cases and 128 controls) were analyzed for 8 organotin concentrations, and subsequent animal experiments were conducted by administering tributyltin (TBT) during critical developmental periods. DNA methylation BeadChip analysis (12 NSCL/P and 12 controls), bisulfite Sequencing analysis (3 NSCL/P and 3 controls mice), and RNA sequencing were performed to explore epigenetic mechanisms. Logistic regression, LASSO regression, support vector machine, random forest, and mediation effect analysis were utilized to identify key genes related to TBT and NSCL/P. Only tributyltin met the detection criteria for further analysis among 8 compounds. The median levels of TBT in cases (8.93 ng/g) were statistically significantly higher than those in controls (5.33 ng/g). Excessive TBT exposure in maternal placenta was associated with an increased risk of NSCL/P (OR = 6.44, 95 % CI, 2.91-14.25) in humans, showing a dose-response relationship (p for trend <0.05). 288 differentially methylated CpG sites in 129 genes were identified between cases and controls. Tributyltin was associated with FGFR2 and SCD hypomethylation, which were identified as potential key genes associated with NSCL/P. Mediation analysis suggested that DNA methylation of FGFR2 and SCD may mediate the impact of TBT on NSCL/P occurrence. TBT exposure during the critical period in mice (GD8.5-GD15.5) can induce progeny NSCL/P. Altered FGFR2 and SCD hypomethylation and gene expression observed in response to TBT exposure in fetal mice. Excessive TBT exposure was associated with increased risks of human NSCL/P. TBT exposure can induce NSCL/P in fetal mice. FGFR2 and SCD were implicated in NSCL/P pathogenesis, potentially mediated by DNA methylation alterations.

Tributyltin-induced oxidative stress causes developmental damage in the cardiovascular system of zebrafish (Danio rerio). ENVIRONMENTAL RESEARCH 2024; 252:118811.

Abstract
Tributyltin (TBT) can be used as an antifouling agent with anticorrosive, antiseptic and antifungal properties and is widely used in wood preservation and ship painting. However, it has recently been found that TBT can be harmful to aquatic organisms. In this study, to gain insight into the effects of TBT with respect to the development of the cardiovascular system in zebrafish embryos, zebrafish embryos were exposed to different concentrations of TBT solutions (0.2 μg/L, 1 μg/L, and 2 μg/L) at 2 h post-fertilization (hpf) TBT exposure resulted in decreased hatchability and heart rate, deformed features such as pericardial edema, yolk sac edema, and spinal curvature in zebrafish embryos, and impaired heart development. Expression of cardiac development-related genes (vmhc, myh6, nkx2.5, tbx5a, gata4, tbx2b, nppa) is dysregulated. Transgenic zebrafish Tg (fli1: EGFP) were used to explore the effects of TBT exposure on vascular development. It was found that TBT exposure could lead to impaired development of intersegmental vessels (ISVs), common cardinal vein (CCV), subintestinal vessels (SIVs) and cerebrovascular. The expression of vascular endothelial growth factor (VEGF) signaling pathway-related genes (flt1, flt4, kdr, vegfa) was downregulated. Biochemical indices showed that ROS and MDA levels were significantly elevated and that SOD and CAT activities were significantly reduced. The expression of key genes for prostacyclin synthesis (pla2, ptgs2a, ptgs2b, ptgis, ptgs1) is abnormal. Therefore, it is possible that oxidative stress induced by TBT exposure leads to the blockage of arachidonic acid (AA) production in zebrafish embryos, which affects prostacyclin synthesis and consequently the normal development of the heart and blood vessels in zebrafish embryos.

Abstract
With the development of agriculture and industry, an increasing number of pollutants are being discharged into the aquatic environment. These pollutants can harm aquatic life. The behavioral characteristics of animals are an external manifestation of their internal mechanisms. Changes in behavior reflect damage and changes in the internal mechanisms. Environmental pollution may lead to behavioral changes not only in the parental generation but also in the offspring that has not been exposed to the pollutants. That is, the intrinsic mechanism that leads to behavioral changes is inheritable. Fish are representative species of aquatic organisms and are commonly used in various research studies. The behavior of fish has also received extensive attention, and the monitoring technology for fish behavior has developed rapidly. This article summarizes the development process of behavior monitoring technology and introduces some of the latest technologies for studying fish behavior. This article also summarizes the intergenerational effects of pollutants on fish behavior, as well as the potential intrinsic and genetic mechanisms that may lead to behavioral changes. This article provides a reference for future relevant neurobehavioral studies.
