Reid CH, Patrick PH, Rytwinski T, Taylor JJ, Willmore WG, Reesor B, Cooke SJ. An updated review of cold shock and cold stress in fish. JOURNAL OF FISH BIOLOGY 2022; 100:1102-1137. [PMID: 35285021 DOI: 10.1111/jfb.15037] [Citation(s) in RCA: 19] [Impact Index Per Article: 9.5] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 10/13/2021] [Revised: 01/23/2022] [Accepted: 03/07/2022] [Indexed: 06/14/2023]
Abstract
Temperature is critical in regulating virtually all biological functions in fish. Low temperature stress (cold shock/stress) is an often-overlooked challenge that many fish face as a result of both natural events and anthropogenic activities. In this study, we present an updated review of the cold shock literature based on a comprehensive literature search, following an initial review on the subject by M.R. Donaldson and colleagues, published in a 2008 volume of this journal. We focus on how knowledge on cold shock and fish has evolved over the past decade, describing advances in the understanding of the generalized stress response in fish under cold stress, what metrics may be used to quantify cold stress and what knowledge gaps remain to be addressed in future research. We also describe the relevance of cold shock as it pertains to environmental managers, policymakers and industry professionals, including practical applications of cold shock. Although substantial progress has been made in addressing some of the knowledge gaps identified a decade ago, other topics (e.g., population-level effects and interactions between primary, secondary and tertiary stress responses) have received little or no attention despite their significance to fish biology and thermal stress. Approaches using combinations of primary, secondary and tertiary stress responses are crucial as a research priority to better understand the mechanisms underlying cold shock responses, from short-term physiological changes to individual- and population-level effects, thereby providing researchers with better means of quantifying cold shock in laboratory and field settings.

Exposure of Drosophila melanogaster to Mancozeb Induces Oxidative Damage and Modulates Nrf2 and HSP70/83. OXIDATIVE MEDICINE AND CELLULAR LONGEVITY 2018; 2018:5456928. [PMID: 30116484 PMCID: PMC6079323 DOI: 10.1155/2018/5456928] [Citation(s) in RCA: 18] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 02/21/2018] [Revised: 05/09/2018] [Accepted: 05/31/2018] [Indexed: 12/21/2022]
Abstract
Mancozeb (MZ), a manganese- and zinc-containing ethylene-bis-dithiocarbamate, is a broad-spectrum fungicide. Harmful effects of this fungicide have been reported in nontarget organisms via a not fully understood mechanism. Drosophila melanogaster has provided remarkable contributions for toxicological studies. This work was aimed at evaluating the biochemical targets and implication of oxidative stress in MZ-mediated toxicity in drosophilas. Exposure of flies for fifteen days to MZ at 5 and 10 mg/mL through the diet impaired locomotor performance and induced fly mortality. In parallel, it caused lipid peroxidation and reactive oxygen species (ROS) formation and Mn overload. MZ inhibited superoxide dismutase and inducted catalase and glutathione S-transferase activities. Nitric oxide and reduced glutathione levels were significantly decreased by MZ. Heat shock proteins (HSP70 and HSP83) and Nrf2 mRNA levels were significantly augmented in MZ-exposed flies. Our study reinforced the use of Drosophila melanogaster as a reliable model for the study of biochemical targets of pesticides, and based on our data, MZ induced oxidative damage and Mn accumulation in a concentration-dependent manner. An adaptative cellular state was inducted by the lower concentration of pesticide, possibly contributing to the slighter damage observed.

Abstract
The mitigating potential of Melissa officinale (MO) (Lamiaceae) against arsenite (As3+)-induced oxidative stress, cytogenotoxicity, and expression of stress genes in fish, Channa punctatus (Bloch), teleost, was explored. After confirming the composition of MO extract, caffeic acid (0.96%), hesperidin (1.73%), naringenin (7.70%), lutenolin (3.29%), kaempferol (11.46%) and hesperetin (6.24%), by HPLC-PDA analysis, the experiment was set up in six groups (G1-G6), each containing 10 specimens. Blood, muscle, gills and liver tissues of control and treated fishes were excised at an interval of 24 till 96 h. Ameliorative potential of MO was confirmed by satisfactory restoration of altered activities of malondialdehyde, hydrogen peroxide, superoxide dismutase, catalase, glutathione peroxidise, glutathione reductase, reduced glutathione and ascorbate peroxidase in G4, G5 and G6, co-exposed with 96 h-LC50/10 As3+ with MO. A significant (p < 0.05) recovery in the frequencies of cytogenotoxic markers, micronuclei, disintegrated nucleus and echinocytes, which were expressed significantly (p < 0.05) in G3 exposed to sub-lethal concentration of ATO alone, was recorded in fish groups (G4, G5 and G6) together treated with 96 h-LC50/10 of ATO and 2, 4 and 8 ppm of MO, respectively. Moreover, the expression of Hsp70 gene was downregulated (2.29-fold); whereas, Hsp27 gene was upregulated (1.16-fold) in G6, the group co-exposed with 96 h-LC50/10 As3+ with 8 ppm of MO in comparison with G3 (3.11-fold for Hsp70; 0.51-fold for Hsp27) after 96 h of exposure period. Thus, it can be inferred that the MO at its tested concentration can be effectively used to mitigate As3+ generated toxicities in C. punctatus.

Abstract
The great albino northern snakehead Channa argus is habitual to only the Sichuan Jialing Rivers System in China, making its introduction difficult to other riverine systems. Here, we characterized heat shock protein 90 (AcaHSP90) and probed its molecular responses toward the environmental stressors that C. argus can face during its introduction and breeding in the other southern latitudes of China. To serve the purpose, cDNA encoding of AcaHSP90 were cloned and characterized in albino C. argus. The cDNA was 2752bps that contained an open reading frame (ORF), encoding a 726-amino-acid polypeptide of 83.35kDa (theoretical isoelectric point [pI]: 4.89). Genomic DNA analysis showed that the AcaHSP90 gene consisted of 7 introns, five conserved amino acid blocks and other motifs or domains. The AcaHSP90 structure was highly similar with the other known HSP90s except those identified in the bacteria. The expression profiles of AcaHSP90 gene in albino C. argus were also investigated after experimentally exposed to different temperature stresses (8.5, 26 and 37°C) and infected with Edwardsiella tarda (strain NO. DL1476) at different time intervals (0, 6, 12, 24, 36, 48, 72h). In addition, the AcaHSP90 expression in different tissues of albino C. argus were also analyzed. The quantitative real-time PCR and western blot analysis revealed tissue-specific AcaHSP90 expressions in control group, and expressions were significantly stimulated in the brain, heart, kidney, liver, muscle and spleen after the heat shock (37°C), while showed no significant difference after the cold treatment (8.5°C). The mRNA levels of AcaHSP90 were also significantly upregulated in the spleen and muscle at 12h and in the kidney at 12 and 48h post pathogen injections. In a nut shell, these novel results showed tissue-specific responses of AcaHSP90 and indicated that this heat shock protein might also be sensitive to pathogen infection, but closely related to the thermal resistance in albino C. argus.

Abstract
DNA methylation, a well-studied epigenetic mark, is important for gene regulation in adulthood and for development. Using genetic and epigenetic approaches, the present study aimed at evaluating the effects of heat stress and copper exposure during zebrafish early embryogenesis when patterns of DNA methylation are being established, a process called reprogramming. Embryos were exposed to 325 μg Cu/L from fertilization (<1 h post fertilization - hpf) to 4 hpf at either 26.5 °C or 34 °C, followed by incubation in clean water at 26.5 °C till 96 hpf. Significant increased mortality rates and delayed hatching were observed following exposure to combined high temperature and Cu. Secondly, both stressors, alone or in combination, significantly upregulated the expression of de novo DNA methyltransferase genes (dnmt3) along with no differences in global cytosine methylation level. Finally, Cu exposure significantly increased the expression of metallothionein (mt2) and heat shock protein (hsp70), the latter being also increased following exposure to high temperature. These results highlighted the sensitivity of early embryogenesis and more precisely of the reprogramming period to environmental challenges, in a realistic situation of combined stressors.

Abstract
Arsenic trioxide (As2O3), a kind of pentavalent arsenic, has recently been linked to disrupted immune function. Heat shock proteins (Hsps), a group of highly conserved proteins, are rapidly synthesised when living organisms are exposed to various stress conditions. The objective of this study is to determine the effects of As2O3 on the expression level of Hsps (Hsp90, Hsp70, Hsp60, Hsp40 and Hsp27) in the immune organs (spleen, thymus and bursa of Fabricius (BF)) of chickens. A total of 72 1-day-old male Hy-line chickens were randomly divided into four groups, including the low-As group (L group), middle-As group (M group), high-As group (H group) and control group (C group). Immune organs were collected, and levels of Hsp messenger RNA (mRNA) and protein were examined on days 30, 60 and 90. The results showed that the levels of Hsp mRNA (Hsp90, Hsp70, Hsp60, Hsp40 and Hsp27) and protein (Hsp70 and Hsp60) expression were significantly increased (p < 0.05 or p < 0.01) in the As2O3 treatment groups compared with the corresponding control groups. Taken together, these results suggest that As2O3 influences the level of Hsps in immune organs.

Abstract
The knowledge about the direct effects of heavy metals on fish leucocytes is still limited. We investigate the in vitro effects of heavy metals (Cd, Hg, Pb or As) on oxidative stress, viability and innate immune parameters of head-kidney leucocytes (HKLs) from European sea bass (Dicentrarchus labrax). Production of free oxygen radicals was induced by Cd, Hg and As, mainly after 30 min of exposure. Cd and Hg promoted both apoptosis and necrosis cell death while Pb and As did only apoptosis, in all cases in a concentration-dependent manner. Moreover, expression of genes related to oxidative stress and apoptosis was significantly induced by Hg and Pb but down-regulated by As. In addition, the expression of the metallothionein A gene was up-regulated by Cd and Pb exposure though this transcript, as well as the heat shock protein 70, was down-regulated by Hg. Cd, methylmercury (MeHg) and As reduced the phagocytic ability, whereas Hg and Pb increased it. Interestingly, all the heavy metals decreased the phagocytic capacity (the number of ingested particles per cell). Leucocyte respiratory burst changed depending on the metal exposure, usually in a time- and dose-manner. Interestingly, the expression of immune-related genes was slightly affected by Cd, MeHg, As or Pb being Hg the form producing the greatest alterations, which included down-regulation of immunoglobulin M and hepcidin, as well as the up-regulation of interleukin-1 beta mRNA levels. This study provides an in vitro approach for elucidating the heavy metals toxicity, and particularly the immunotoxicity, in fish leucocytes.

Abstract
The genotoxic effects of a mixture of 13 volatile organic compounds (VOCs) on total DNA profiles and the expression of heat shock proteins (HSPs) HSP26, HSP60, HSP70, and HSP83 in fruit fly tissues were examined. Drosophila melanogaster Oregon R(+), reared under controlled conditions on artificial diets, was treated with 13 VOCs commonly found in water at concentrations of 10, 20, 50, and 75 ppb for 1 and 5 days. Band changes were clearly detected in random amplified polymorphic DNA assay, especially at the 50- and 75-ppb exposure levels, for both treatment periods. In addition, there were clear differences in the band profiles of the treated and untreated flies with changes in the band intensity and the loss/appearance of bands. Although the genomic template stability (GTS) exhibited irregular changes at the first day, significant decreases in GTS were observed after 5 days of VOC application. The lowest GTS value (27.77 ± 1.96 %) was detected at the 75-ppb level after 5 days of the treatment. Quantitative real-time polymerase chain reaction analysis showed a significant increase in the relative expression of HSP26 and HSP60 after 1 and 5 days of the treatment, respectively. The expression of HSP70 increased significantly at all treatment concentrations and times. However, the greatest increase in expression level of HSP70 (4.2-fold) occurred at 20 ppb after 5 days of the treatment. HSP83 was the least affected by exposure to the VOCs. We conclude that trace levels of a mixture of VOCs can exert genotoxic effects on both total DNA and HSP levels in Drosophila.

Abstract
The immunotoxic effects of heavy metals on blood leukocytes of sea bass (Dicentrarchus labrax) were examined. The cells, separated by a discontinuous Percoll-gradients, were exposed in vitro to various sublethal concentrations of cadmium and copper (10(-7)M, 10(-5)M, and 10(-3)M) and their immunotoxic effect was then evaluated by measuring neutral red uptake, MTT assay, DNA fragmentation and Hsp70 gene expression. First of all, we demonstrated that the cells treated in vitro could incorporate Cd and Cu. A relationship between heavy metal exposure and dose-time-dependent alterations in responses of leukocytes from blood was found for both metals, but copper was more immunotoxic than cadmium in all assays performed. A significant reduction in the cells׳ ability to uptake neutral red and viability by MTT assay was recorded, indicating that both cadmium and copper could change the membrane permeability, inducing cellular apoptosis when the concentration of metals reached 10(-3)M. The apoptotic effect may also explain the high level of cytotoxicity found when the leukocytes were exposed to higher concentration of metals. These results demonstrated that toxic effect of copper and cadmium affect on the mechanisms of cell-mediated immunity reducing the immune defences of the organism.

Abstract
Heat shock protein 90 (HSP90) is a highly conserved molecular chaperone important in the maturation of a broad spectrum of proteins. In order to evaluate the effect of copper (Cu(2+)) and cadmium (Cd(2+)) on the expression of HSP90 from Tanichthys albonubes (designated TaHSP90), the full-length complementary DNA (cDNA) of TaHSP90 was cloned using reverse transcription PCR and rapid amplification of cDNA ends (RACE) techniques. A 2,687-bp sequence was sequenced and consisted of an open reading frame (ORF) of 2,181 bp encoding a polypeptide of 727 amino acids with five HSP90 family signatures. Homologous analysis revealed that TaHSP90 gene shared high similarity with other known HSP90 genes and belonged to HSP90β subtype. Fluorescent real-time quantitative PCR was used to examine the expression pattern of TaHSP90β mRNA in different tissues (liver, muscle, gill, fin, eye, ovary, intestine and brain), and the result indicated that TaHSP90β was widely expressed in all examined tissues at different levels. Sensitivity of TaHSP90β to copper and cadmium was examined by exposing fish to different concentrations of Cu(2+) (0, 13.50 and 27.00 μg/L) and Cd(2+) (0, 1.15, 2.31 mg/L) for 24, 48, 72 and 96 h, respectively. The copper treatment induced TaHSP90β expression slight increase only at 24 and 48 h, while cadmium treatment caused slight down-regulation of TaHSP90β only 72 and 96 h. Our data suggest that the cloning and expression analysis of T. albonubes HSP90β gene provided useful molecular information of T. albonubes responses in stress conditions and potential ways to monitor the chronic stressors in T. albonubes culture environments.

Abstract
Exposure to EMFs (electromagnetic fields) results in a number of important biological changes, including modification of genetic expression. We have investigated the effect of 60 Hz sinusoidal EMFs at a magnetic flux density of 80 μT on the expression of the luciferase gene contained in a plasmid labelled as pEMF (EMF plasmid). This gene construct contains the specific sequences for the induction of hsp70 (heat-shock protein 70) expression by EMFs, as well as the reporter for the luciferase gene. The pEMF vector was electrotransferred into quadriceps muscles of BALB/c mice that were later exposed to EMFs. Increased luciferase expression was observed in mice exposed to EMFs 2 h daily for 7 days compared with controls (P<0.05). These data along with other reports in the literature suggest that EMFs can have far-reaching effects on the genome.

Abstract
The influence of the following heavy metals, copper (Cu), zinc (Zn), cadmium (Cd) and lead (Pb), on haemocytes of the house fly Musca domestica L. was studied under laboratory conditions. House fly larvae were exposed to low or high, semi-lethal concentrations of metals. These particular metals were selected because they are present in polluted environments in Poland. In addition, we studied expression of the stress proteins HSP70 and HSP72 in haemocytes collected from larvae that had been exposed to heavy metal. The obtained results showed changes in haemocytes morphology and phagocytotic plasticity in the experimental flies in comparison to control. The number of prohaemocytes, regarded as stem cells, increased, while granulocytes, responsible for phagocytosis, decreased. However, we have not detected any clear changes in expression of HSP70 or HSP72 in flies treated with low or high concentrations of the heavy metals.

Krause M, Rodrigues-Krause JDC. Extracellular heat shock proteins (eHSP70) in exercise: Possible targets outside the immune system and their role for neurodegenerative disorders treatment. Med Hypotheses 2010; 76:286-90. [PMID: 21071151 DOI: 10.1016/j.mehy.2010.10.025] [Citation(s) in RCA: 35] [Impact Index Per Article: 2.5] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/27/2010] [Revised: 10/12/2010] [Accepted: 10/13/2010] [Indexed: 11/18/2022]
Abstract
The intracellular heat shock protein 70kDa (iHSP70) is a universal marker of stress protein whose expression is induced by different cell stressors, such as heat, metabolite deprivation, redox imbalances and also during physical exercise. The activation of the iHSP70 is sine qua non for the promotion of tissue repair, since the expression of this chaperone confers cytoprotection and also exerts anti-inflammatory effects. On the other hand, exercise also induces the appearance of HSP70 in the extracellular medium (eHSP70) but, so far, the eHSP70 function has been mainly attributed to the activation of the immune system, seeming to perform an opposite function from the iHSP70. Since a moderate intensity exercise bout induces a general anti-inflammatory response even in the presence of an elevated eHSP70, this protein could carry out other functions rather than immune activation. Because exercise generates heat and metabolic challenges (especially on glucose metabolism) we suggests that the motoneurons, a very active (possibly one of the most stressed cells during exercise) and also very sensitive cells to heat and glucose metabolism imbalances, could be the major sites for the eHSP70 function. Due to the importance of the iHSP70 for repair and stress adaptation, this protein must be present in abundance on the site of stress and, because of its intrinsic inability response to stress [low heat shock factor 1 (HSF-1) activation] and the structure of the motoneurons (very long cells), the iHSP70, produced on the very far nucleus, is not appropriately transported through the axon to the axon terminal, were it is required. Then, during the exercise, the released eHSP70 can be internalized by the motoneurons and act as intracellular chaperons, protecting this cell against oxidative damage, protein denaturation and many others. Since a decreased iHSP70 expression capacity is associated with neurodegeneration diseases (such as Parkinson, polyglutamine, Amyotrophic lateral sclerosis, Alzheimer's, Huntington's and many others), the understanding of the physiological function of the extracellular HSP70 could be helpful on the treatment of neurodegenerative and other neuronal diseases. Besides that, it could explain some of the beneficial effects of the pharmacological HSP70 activators and also the beneficial effects of the exercise among neuronal cells during neurodegenerative-inducing diseases.
