Liu J, Zhang L, Xu F, Zhang P, Song Y. Chronic administration of triclosan leads to liver fibrosis through hepcidin-ferroportin axis-mediated iron overload. J Environ Sci (China) 2024; 137:144-154. [PMID: 37980003 DOI: 10.1016/j.jes.2023.02.004] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/02/2022] [Revised: 02/01/2023] [Accepted: 02/03/2023] [Indexed: 11/20/2023]
Abstract
Triclosan (TCS) has been manufactured as an antibacterial compound for half a century. Currently, it is widely used in various personal care products; however, its potential adverse effects raise a lot of attention. Here, we create a long-term oral administration mouse model and identify the corresponding hepatotoxicity of TCS. We discover that daily intragastric administration of 10 mg/kg TCS to mice for 12 weeks results in severe hepatic fibrosis. Further study displays that hepatic iron increased 18%, 23% and 29% upon oral TCS treatment for 4, 8 and 12 weeks, respectively. Accompanied by hepatic iron variation, splenic and duodenal iron are increased, which indicates systemic iron disorder. Not only excessive iron accumulated in the liver, abnormal hepatic malondialdehyde, prostaglandin synthase 2 and glutathione peroxidase 4 are pointed to ferroptosis. Additional study uncovers that hepcidin expression increases 7%, 10%, 4% in serum and 2.4-, 4.8-, and 2.3-fold on transcriptional levels upon TCS exposure for 4, 8 and 12 weeks, individually. Taken together, the mice in the TCS-treated group show disordered systemic iron homeostasis via the upregulated hepatic hepcidin-ferroportin axis. Meanwhile, both hepatic iron overload (systemic level) and hepatocyte ferroptosis (cellular level) are accused of TCS-induced liver fibrosis. Ferriprox®, an iron scavenger, significantly ameliorates TCS-induced liver fibrosis. In summary, this study confirms the impact of TCS on liver fibrosis; a critical signal pathway is also displayed. The significance of the current study is to prompt us to reevaluate the "pros and cons" of TCS applications.

CHEMOSPHERE 2023; 344:140373. [PMID: 37806324 DOI: 10.1016/j.chemosphere.2023.140373] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/21/2023] [Revised: 09/30/2023] [Accepted: 10/04/2023] [Indexed: 10/10/2023]
Abstract
The increasing use of chemicals and their release into aquatic ecosystems are harming aquatic biota. Despite extensive ecotoxicological research, many environmental pollutants' ecological effects are still unknown. This study examined the spatial avoidance, behavioural and biochemical impacts of ibuprofen, irgarol, and terbuthylazine on the early life stages of zebrafish (Danio rerio) under a range of ecologically relevant concentrations (0-500 μg/L). Embryos were exposed following the OECD guideline "fish embryo toxicity test" complemented with biochemical assessment of AChE activity and behavioural analyses (swimming activity) using the video tracking system Zebrabox. Moreover, spatial avoidance was assessed by exposing 120 hpf-old larvae of D. rerio to a gradient of each chemical, by using the heterogeneous multi-habitat assay system (HeMHAS). The results obtained revealed that the 3 compounds delayed hatching at concentrations of 50 and 500 μg/L for both ibuprofen and irgarol and 500 μg/L for terbuthylazine. Moreover, all chemicals elicited a dose-dependent depression of movement (swimming distance) with LOEC values of 5, 500 and 50 μg/L for ibuprofen, irgarol and terbuthylazine, respectively. Zebrafish larvae avoided the three chemicals studied, with 4 h-AC50 values for ibuprofen, irgarol, and terbuthylazine of 64.32, 79.86, and 131.04 μg/L, respectively. The results of the HeMHAS assay suggest that larvae may early on avoid (just after 4 h of exposure) concentrations of the three chemicals that may later induce, apical and biochemical effects. Findings from this study make clear some advantages of using HeMHAS in ecotoxicology as it is: ecologically relevant (by simulating a chemically heterogeneous environmental scenario), sensitive (the perception of chemicals and the avoidance can occur at concentrations lower than those producing lethal or sublethal effects) and more humane and refined approach (organisms are not mandatorily exposed to concentrations that can produce individual toxicity).

Abstract
Xenobiotic Triclosan (TCS) is of great concern because of its existence in a variety of personal, household and healthcare products and continuous discharge in water worldwide. Excessive use of TCS-containing sanitizers and antiseptic products during the COVID-19 pandemic further increased its content in aquatic ecosystems. The present study deals with the cyto-genotoxic effects and biochemical alterations in the hatchlings of Labeo rohita on exposure to environmentally relevant concentrations of TCS. Three-days-old hatchlings were exposed to tap water, acetone (solvent control) and 4 environmentally relevant concentrations (6.3, 12.6, 25.2 and 60 µg/L) of TCS for 14 days and kept for a recovery period of 10 days. The significant concentration-dependent decline in cell viability but increase in micronucleated cells, nucleo-cellular abnormalities (NCAs) and DNA damage parameters like tail length, tail moment, olive tail moment and percent of tail DNA after exposure persisted till the end of recovery period. Glucose, triglycerides, cholesterol, total protein, albumin, total bilirubin, uric acid and urea (except for an increase at 60 µg/L) showed significant (p ≤ 0.05) concentration-dependent decrease after 14 days of exposure. The same trend (except for triglycerides, albumin and total bilirubin) continued till 10 days post exposure. In comparison to control, transaminases (alanine and aspartate aminotransferases) increased (p ≤ 0.05) after exposure as well as the recovery period, while a decline in alkaline phosphatase after exposure was followed by a significant increase during the recovery period. The results show that the environmentally relevant concentrations of TCS cause deleterious effects on the hatchlings of L. rohita.

Abstract
The evaluation of toxic effects in stressful environmental conditions can be determined through the imbalance between exogenous factors (environmental contaminants) and enzymatic and non-enzymatic defenses in biological systems. The use of fish for the identification of alterations in biochemical biomarkers provides a comprehensive vision of the effects that pharmaceutical products cause in the aquatic ecosystem, as they are organisms with high sensitivity to contaminants, filtering capacity, and potential for environmental toxicology studies. A wide range of pharmaceuticals can stimulate or alter a variety of biochemical mechanisms, such as oxidative damage to membrane lipids, proteins, and changes in antioxidant enzymes. This review includes a summary of knowledge of the last 20 years, in the understanding of the different biochemical biomarkers generated by exposure to pharmaceuticals in fish, which include different categories of pharmaceutical products: NSAIDs, analgesics, antibiotics, anticonvulsants, antidepressants, hormones, lipid regulators and mixtures. This review serves as a tool in the design of studies for the evaluation of the effects of pharmaceutical products, taking into account the most useful biomarkers, type of matrix, enzyme alterations, all taking the pharmaceutical group of interest.

Abstract
In the current study, Triclosan (TCS, a commonly used antimicrobial agent) induced alterations in biochemical parameters and gene expression were recorded in the larvae of Labeo rohita after 96 h exposure and 10 days recovery period to find out health status biomarkers. 96 h exposure to 0.06, 0.067 and 0.097 mg/L TCS significantly declined the levels of glucose, triglycerides, urea and uric acid and activity of alkaline phosphatase (ALP), glutamic oxaloacetic transaminase (GOT) and glutamic pyruvic transaminase (GPT). There was a non-significant decline in the levels of cholesterol and total protein but albumin and total bilirubin showed no change. After 10 days of recovery period, trend was opposite for glucose, urea and ALP only. Decline in the expression of trypsin and pancreatic amylase and elevation in creatine kinase during exposure to TCS showed a reverse trend after recovery period. However, concentration dependent elevation of chymotrypsin persisted till the end of recovery period. Principal Component Analysis (PCA) showed association of total protein, ALP, GOT, creatine kinase and pancreatic amylase with PC1 after exposure as well as recovery period. Therefore, these can be considered as important biomolecules for identification of health status of TCS stressed fish.
