[PMID: 38672907 PMCID: PMC11048948 DOI: 10.3390/foods13081235] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/27/2024] [Revised: 04/12/2024] [Accepted: 04/16/2024] [Indexed: 04/28/2024] Open
Abstract
Anthropogenic activities lead to the spread of chemicals and biological materials, including plastic waste, toxic metals, and pharmaceuticals, of which the impact on the Mediterranean Sea is of high concern. In this context, the EU Interreg Italy-Albania-Montenegro Project "ADRINET (Adriatic Network for Marine Ecosystem) _244" (2018-2020) arises. It aims to carry out biomonitoring campaigns in the main commercial interest of fish and cephalopod species, such as Sparus aurata, Dicentrarchus labrax, Sepia spp., and Loligo spp. sampled in three different subregions of the Mediterranean Sea. The presence of the main environmental contaminants, such as cadmium, microplastics, and antibiotics was investigated in these seafood samples. Contamination by cadmium and antibiotics in the seafood investigated in our study was negligible. However, a high value of microplastics was detected in the stomach and gut of Sparus aurata and Dicentrarchus labrax. Overall, even though the presence of microplastics needs to be investigated by further studies, the results confirmed that the environmental conditions of the three bays investigated by the ADRINET project partners (Italy, Albania, Montenegro) are positive and not affected by intensive anthropogenic activity.

MARINE POLLUTION BULLETIN 2024; 201:116284. [PMID: 38522335 DOI: 10.1016/j.marpolbul.2024.116284] [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: 12/21/2023] [Revised: 03/19/2024] [Accepted: 03/19/2024] [Indexed: 03/26/2024]
Abstract
Antioxidant responses of juvenile sole exposed to seawater acidification (SA) and Cd were investigated. SA increased lipid peroxidation (LPO) in the fish, independent of Cd concentrations. Cd at medium and high levels inflated LPO under no or moderate SA conditions. This effect was absent under high SA levels, due to SA effect exceeding and obscuring Cd effect. SA and Cd collaborated to provoke LPO, with SOD and CAT being stimulated to defend against oxidative stress, while those related to GSH redox cycle were inhibited under SA exposure. Responses of GSH-related antioxidants to Cd impact varied contingent on their interactions with SA. This defensive strategy was insufficient to protect fish from increased LPO. Antioxidants responded more sensitively to SA than Cd exposure. GSH, GR, SOD and CAT are sensitive biomarkers for SA conditions. The findings offer insights into assessing fish's antioxidant defense strategy under Cd and SA circumstances in natural habitats.

Abstract
Heavy metal pollution has significant impacts on aquatic fauna and flora. It accumulates in marine organisms, both plants and animals, which are then consumed by humans. This can lead to various health problems, such as organ damage and the development of cancer. Additionally, this pollution causes biological magnification, where the toxicity concentration gradually increases as aquatic organisms continuously accumulate metals. This process results in apoptotic mechanisms, antioxidant defence, and inflammation, which are reflected at the gene expression level. However, there is limited research on specific heavy metals and their effects on fish organs. The concentration of metal contamination and accumulation in different tropical environments is a concern due to their toxicity to living organisms. Therefore, this review focuses on determining the influences of metals on fish and their effects on specific organs, including DNA alterations.

Lange A, Segner H. The Role of Glutathione and Sulfhydryl Groups in Cadmium Uptake by Cultures of the Rainbow Trout RTG-2 Cell Line. Cells 2023; 12:2720.

Abstract
The aim of this study is to investigate the role of cellular sulfhydryl and glutathione (GSH) status in cellular cadmium (Cd) accumulation using cultures of the rainbow trout cell line RTG-2. In a first set of experiments, the time course of Cd accumulation in RTG-2 cells exposed to a non-cytotoxic CdCl2 concentration (25 μM) was determined, as were the associated changes in the cellular sulfhydryl status. The cellular levels of total GSH, oxidized glutathione (GSSG), and cysteine were determined with fluorometric high-performance liquid chromatography (HPLC), and the intracellular Cd concentrations were determined with inductively coupled plasma mass spectrometry (ICP-MS). The Cd uptake during the first 24 h of exposure was linear before it approached a plateau at 48 h. The metal accumulation did not cause an alteration in cellular GSH, GSSG, or cysteine levels. In a second set of experiments, we examined whether the cellular sulfhydryl status modulates Cd accumulation. To this end, the following approaches were used: (a) untreated RTG-2 cells as controls, and (b) RTG-2 cells that were either depleted of GSH through pre-exposure to 1 mM L-buthionine-SR-sulfoximine (BSO), an inhibitor of glutathione synthesis, or the cellular sulfhydryl groups were blocked through treatment with 2.5 μM N-ethylmaleimide (NEM). Compared to the control cells, the cells depleted of intracellular GSH showed a 25% reduction in Cd accumulation. Likewise, the Cd accumulation was reduced by 25% in the RTG-2 cells with blocked sulfhydryl groups. However, the 25% decrease in cellular Cd accumulation in the sulfhydryl-manipulated cells was statistically not significantly different from the Cd accumulation in the control cells. The findings of this study suggest that the intracellular sulfhydryl and GSH status, in contrast to their importance for Cd toxicodynamics, is of limited importance for the toxicokinetics of Cd in fish cells.

ECOTOXICOLOGY AND ENVIRONMENTAL SAFETY 2023; 267:115672.

Abstract
This experiment aimed to investigate the protective effects of berberine on copper-induced liver and gill toxicities in freshwater grouper (Acrossocheilus fasciatus). Fish (initial weight 1.56 ± 0.10 g) were randomly distributed into 12 tanks (80 L, 20 fish per tank) and divided into four experimental groups: The control group, exposed to 0.02 mg/L Cu2+ (Cu group), exposed to 0.02 mg/L Cu2+ and fed 100 mg/kg berberine (BBR100 group), and exposed to 0.02 mg/L Cu2+ and fed 400 mg/kg berberine (BBR400 group). After a 30-day experiment, the results showed that berberine significantly increased the activities of catalase and glutathione peroxidase in the liver, gills, and serum inhibited by Cu2+ exposure (P < 0.05). Berberine inclusion significantly decreased the activities of lysozyme and acid phosphatase, as well as the content of immunoglobulin M compared to the Cu group (P < 0.05). Berberine significantly suppressed the expression of the proinflammatory cytokines interleukin-1β, interleukin-6 signaling transducer, and NLR family pyrin domain containing 3 in the liver and gills induced by Cu2+ exposure while downregulating the expression of the anti-inflammatory cytokine transforming growth factor β1. Additionally, berberine significantly reduced the activities of the liver injury markers alanine transaminase and aspartate transaminase, the levels of total cholesterol and triglyceride in serum, as well as alleviated the histopathological damage in the liver and gills caused by Cu2+ exposure. In summary, berberine enhanced antioxidant capacity, mitigated inflammation, and exerted significant protective effects on liver and gill damage in freshwater grouper under Cu2+ exposure.

Toxic effects of combined exposure to cadmium and nitrate on intestinal morphology, immune response, and microbiota in juvenile Japanese flounder (Paralichthys olivaceus). AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2023; 264:106704. [PMID: 37813047 DOI: 10.1016/j.aquatox.2023.106704] [Citation(s) in RCA: 2] [Impact Index Per Article: 2.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 08/09/2023] [Revised: 09/21/2023] [Accepted: 09/23/2023] [Indexed: 10/11/2023]
Abstract
Cadmium (Cd2+) and nitrate (NO3-) are important environmental pollutants in the offshore marine ecological environment. However, limited research has explored their combined effects, particularly regarding their impact on the microbiota and intestinal health of marine fish. In this study, juvenile Japanese flounders (P. olivaceus) were immersed in seawater samples with different combinations of Cd2+ (0, 0.2, and 2 mg/L) and NO3- (0 and 80 mg/L NO3N) for 30 days to explore their toxic impacts on intestinal morphology, tight junction (TJ) barrier, immune response, and microbiota. Our results showed that Cd2+ or NO3- exposure alone led to histopathological damage of the gut, while their co-exposure aggravated intestinal damage. Moreover, co-exposure substantially decreased TJ-related gene expression, including occludin, claudin-10, and ZO-2, suggesting increased TJ permeability in the gut. Regarding the immune response, we observed upregulated expression of immune-related markers such as HSP40, IL-1β, TNF-α, and MT, suggesting the onset of intestinal inflammation. Furthermore, Cd2+ and NO3- exposure led to changes in intestinal microflora, characterized by decreased the abundance of Sediminibacterium and NS3a_marine_group while increasing the prevalence of pathogens or opportunistic pathogens such as Ralstonia, Proteus, and Staphylococcus. This alteration in microbiota composition increased network complexity and α-diversity, ultimately causing dysbiosis in the fish gut. Additionally, combined exposure resulted in metabolic disorders that affected the predicted functions of the intestinal microbiota. Overall, our study demonstrates that Cd2+-NO3- co-exposure amplifies the deleterious effects compared to single exposure. These findings enhance our understanding of the ecological risks posed by Cd2+-NO3- co-exposure in marine ecosystems.
