AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2021; 233:105771. [PMID: 33578303 DOI: 10.1016/j.aquatox.2021.105771] [Citation(s) in RCA: 10] [Impact Index Per Article: 3.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 09/21/2020] [Revised: 01/24/2021] [Accepted: 02/01/2021] [Indexed: 06/12/2023]
Abstract
Present study aims to investigate interaction of molecular chaperons (heat shock protein 70, heat shock protein 90) with transcriptional factors (nuclear factor kappa B/nuclear factor E2-related factor 2/Kelch-like ECH-associated protein 1) to evaluate their role during metal induced stress in fish hepatocytes. Adult Puntius ticto were exposed to lead nitrate at 0 mg/l (control), 1/50th (0.04 mg/l) and 1/20th (0.12 mg/l) of LC50 for 30 days and sacrificed to collect liver tissues. Activity of selected liver enzymes, antioxidants and metallothionein were analyzed. Levels of heat shock protein 70, heat shock protein 90, nuclear factor kappa B, nuclear factor E2-related factor 2 and Kelch-like ECH-associated protein 1 were also measured. Liver enzymes showed a significant increase (p < 0.05) in both Pb exposed groups indicating that the liver might be at risk of damage. Increased level of lipid peroxidation due to metal stress was marked by significant increase (p < 0.05) in malondialdehyde level in fish exposed to the higher Pb concentration compared to control (+ 13.7 %). Significant increase (p < 0.05) in gluthathione reductase (+ 35 %, + 39.2 %), glutathione s-transferase (+ 22.4 %, + 50.4 %) activities and decrease in reduced glutathione level (- 6.75 %, - 12.25 %) in fish exposed to both lower and higher Pb concentration compared to control also indicated metal induced oxidative damage in fish liver. Super oxide dismutase and catalase activities increased significantly (p < 0.05) during exposure to lower Pb concentration, while decreased significantly (p < 0.05) during exposure to higher Pb concentration compared to those in control. Significant (P < 0.05) increase (+ 52.63 %, + 89.47 %) in metallothionein in Pb exposed groups confirmed its role in detoxification process of the metal. Heat shock protein 70 and heat shock protein 90 expression levels increased significantly (p < 0.05) during metal exposure indicating their role as modulator of stress-induced antioxidant protein remodelling. A positive correlation between nuclear factor kappa B/nuclear factor E2-related factor 2/Kelch-like ECH-associated protein 1 with gluthathione regulatory enzymes (gluthathione reductase and glutathione s-transferase) was noted. Current study effectively illuminates the critical role of different factors (heat shock proteins/nuclear factor kappa B/nuclear factor E2-related factor 2/Kelch-like ECH-associated protein 1) to influence the expression and synthesis of antioxidants and other functional enzymes in lead-exposed fish liver.

THE SCIENCE OF THE TOTAL ENVIRONMENT 2017; 584-585:813-827. [PMID: 28159302 DOI: 10.1016/j.scitotenv.2017.01.125] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/15/2016] [Revised: 01/17/2017] [Accepted: 01/18/2017] [Indexed: 06/06/2023]
Abstract
UNLABELLED A 2D-DIGE/MS approach was used to assess protein abundance differences in the red swamp crayfish Procambarus clarkii from polluted aquatic ecosystems of Doñana National Park and surrounding areas with different pollution loads. Procambarus clarkii accumulated metals in the digestive glands and gills reflecting sediment concentrations. We first stated that, probably related to elements accumulation, pollution increased oxidative damage in P. clarkii tissues, as shown by the thiol oxidation status of proteins and MDA levels. In these animals, the altered redox status might be responsible for the deregulated abundance of proteins involved in cellular responses to oxidative stress including protein folding, mitochondrial imbalance and inflammatory processes. Interestingly, polluted P. clarkii crayfish also displayed a metabolic shift to enhanced aerobic glycolysis, most likely aimed at generating ATP and reduction equivalents in an oxidative stress situation that alters mitochondrial integrity. The deregulated proteins define the physiological processes affected by pollutants in DNP and its surrounding areas and may help us to unravel the molecular mechanisms underlying the toxicity of environmental pollutants. In addition, these proteins might be used as exposure biomarkers in environmental risk assessment. The results obtained might be extrapolated to many other locations all over the world and have the added value of providing information about the molecular responses of this environmentally and economically interesting animal. SIGNIFICANCE Metal content in digestive gland and gills of P. clarkii crayfish reflects their contents in sediments at sites of Doñana National Park and its surroundings. Accumulation of essential and toxic transition metals is paralleled by clear signs of oxidative stress to lipids and proteins and by significant deregulation of many proteins involved in protein folding, mitochondrial respiratory imbalance and inflammatory response. These results indicate that P. clarkii is an excellent bioindicator to be used in aquatic ecosystems quality monitoring. Additionally, results evidence that the anthropogenic activities carried out around Doñana National Park represent an extremely serious threat to this unique Biosphere Reserve and pose a risk to the environment and their inhabitants health. The identified deregulated proteins provide information about the metabolic pathways and/or physiological processes affected by pollutant-elicited oxidative stress, may also be useful as biomarkers of environmental pollution and have the added value of providing information about the molecular responses of this environmentally and economically interesting animal.

Abstract
Ucides cordatus (Linnaeus, 1763) is a hypo-hyper-regulating mangrove crab possessing gills for respiratory and osmoregulatory processes, separated in anterior and posterior sections. They also have hepatopancreas, which is responsible for digestion and absorption of nutrients and detoxification of toxic metals. Each of these organs has specific cells that are important for in vitro studies in cell biology, ion and toxic metals transport. In order to study and characterize cells from gills and hepatopancreas, both were separated using a Sucrose Gradient (SG) from 10 to 40% and cells in each gradient were characterized using the vital mitochondrial dye DASPEI (2-(4-dimethylaminostyryl)-N- ethylpyridinium iodide) and Trichrome Mallory's stain. Both in 20 and 40% SG for gill cells and 30% SG for hepatopancreatic cells, a greater number of cells were colored with DASPEI, indicating a larger number of mitochondria in these cells. It is concluded that the gill cells present in 20% and 40% SG are Thin cells, responsible for respiratory processes and Ionocytes responsible for ion transport, respectively. For hepatopancreatic cells, the 30% SG is composed of Fibrillar cells that possess larger number of membrane ion and nutrient transporters. Moreover, the transport of toxic metal cadmium (Cd) by isolated hepatopancreatic cells was performed as a way of following cell physiological integrity after cell separation and to study differences in transport among the cells. All hepatopancreatic cells were able to transport Cd. These findings are the first step for further work on isolated cells of these important exchange epithelia of crabs, using a simple separation method and to further develop successful in vitro cell culture in crabs.

Abstract
The bivalve Mizuhopecten yessoensis has been greatly impacted by marine pollutants in northern China. To elucidate the toxicological mechanism of copper exposure on the immune system, we investigated differentially expressed genes (DEGs) and transcript abundance in M. yessoensis gill tissue using the deep-sequencing platform Illumina HiSeq™ 2000. In total, 1312 and 2237 genes were identified as significantly up- or down-regulated, respectively. In addition, significant enrichment analysis identified 9 GO terms and 38 pathways involved in the response to copper exposure. The analysis of immune-related transcripts revealed a complex repertoire of innate recognition receptors, including toll-like receptors, NOD-like receptors and RIG-like receptors. Downstream pathway effectors, such as apoptotic, lysosomal and C-type lectin transcripts, were also analyzed. These results will provide a resource for subsequent gene expression studies regarding heavy metal exposure and the identification of copper-sensitive biomarkers to monitor the aquaculture of M. yessoensis.

Abstract
Mass staining of decapod females carrying eggs, with subsequent identification of hatched larvae in the environment, is a research tool with great potential for field ecologists wishing to track the movements of larvae. For this to be achieved, however, numerous requirements must be met. These include adequate dye solubility, short staining time, dye penetration through different tissues, dye retention within the organism, absence of toxic and behavioral effects, low visibility to predators of stained larvae, no loss of staining owing to preservatives and low cost. The dye, neutral red, appears to meet most of these requirements. This dye was used in aliquots of 0.7 g/770 ml seawater applied to the females of Norway lobster (Nephrops norvegicus) and European lobster (Homarus gammarus) for 10 min. This procedure stained lobster eggs and embryos so that hatched larvae could be distinguished easily by fluorescence microscopy from larvae that hatched from unstained eggs. Stained larvae that were preserved in 4% formaldehyde in seawater were still stained after 1 year. Larvae should not come in contact with ethanol, because it extracts the dye rapidly.

Kamunde C, MacPhail R. Subcellular interactions of dietary cadmium, copper and zinc in rainbow trout (Oncorhynchus mykiss). AQUATIC TOXICOLOGY (AMSTERDAM, NETHERLANDS) 2011; 105:518-527.

Abstract
Interactions of Cu, Cd and Zn were studied at the subcellular level in juvenile rainbow trout (Oncorhynchus mykiss) fed diets containing (μg/g) 500 Cu, 1000 Zn and 500 Cd singly and as a ternary mixture for 28 days. Livers were harvested and submitted to differential centrifugation to isolate components of metabolically active metal pool (MAP: heat-denaturable proteins (HDP), organelles, nuclei) and metabolically detoxified metal pool (MDP: heat stable proteins (HSP), NaOH-resistant granules). Results indicated that Cd accumulation was enhanced in all the subcellular compartments, albeit at different time points, in fish exposed to the metals mixture relative to those exposed to Cd alone, whereas Cu alone exposure increased Cd partitioning. Exposure to the metals mixture reduced (HDP) and enhanced (HSP, nuclei and granules) Cu accumulation while exposure to Zn alone enhanced Cu concentration in all the fractions analyzed without altering proportional distribution in MAP and MDP. Although subcellular Zn accumulation was less pronounced than that of either Cu or Cd, concentrations of Zn were enhanced in HDP, nuclei and granules from fish exposed to the metals mixture relative to those exposed to Zn alone. Cadmium alone exposure mobilized Zn and Cu from the nuclei and increased Zn accumulation in organelles and Cu in granules, while Cu alone exposure stimulated Zn accumulation in HSP, HDP and organelles. Interestingly, Cd alone exposure increased the partitioning of the three metals in MDP indicative of enhanced detoxification. Generally the accumulated metals were predominantly metabolically active: Cd, 67-83%; Cu, 68-79% and Zn, 60-76%. Taken together these results show both competitive and cooperative interactions dependent on the subcellular fraction, metal, exposure duration and relative metal exposure concentrations. Competitive interactions likely result from ionic mimicry with the metals displacing each other from common binding sites, whereas cooperative interactions suggest increased abundance of metal binding sites and/or existence of metal-specific non-interacting binding sites in some of the fractions. Moreover, the changes in subcellular distribution of the biometals Cu and Zn due to Cd exposure together with the shifts of the metals between MAP and MDP observed may have toxicological consequences.
