“…Lysozyme is used as an immunity index. When the external environment changes rapidly, the stress occurring in the body suppresses immune function, which activates lysozyme (Wang et al 2008). The current results are in agreement with those of Cheng et al (2009) and Shin et al (2010b), who found that lysozyme activity decreased in olive flounder and orange-spotted grouper, Epinephelus coioides, exposed to hypoosmotic and low-temperature conditions, respectively.…”

We studied oxidative stress in cinnamon clownfish exposed to hypoosmotic (35 psu 0 17.5 psu and 17.5 psu with prolactin (PRL)) and low temperature (288C 0 248C and 208C) conditions by measuring the expression and activity of Cu/Zn-superoxide dismutase (Cu/Zn-SOD), catalase (CAT), and glutathione peroxidase (GPX). The expression and activity of the antioxidant enzymes were significantly higher after the fish were exposed to 248C, 208C, and 17.5 psu, and expression was repressed by PRL treatment. Furthermore, we measured H 2 O 2 and lipid peroxidation levels and found that they were significantly higher after exposure to the hypoosmotic and low-temperature environments. Additionally, we investigated changes in plasma AST and ALT levels after exposure to low temperature and hypoosmotic stress. These levels increased upon exposure of the clownfish to 248C, 208C, and 17.5 psu, but the levels of these parameters decreased in the 17.5 psu with PRL treatment during a salinity change. The results indicate that hypoosmotic and low-temperature conditions induce oxidative stress in cinnamon clownfish and that the parameters tested in this study may be indices of oxidative stress in the cinnamon clownfish.

“…The importance of GST for cell defense during osmotic stress has been demonstrated in several marine invertebrates, e.g., in bivalve species of the Veneridae family (Carregosa et al, 2014). Other antioxidant proteins also were involved in overcoming salinity and hypoxic stress: superoxide-anion dismutase and catalase in holothuria Apostichopus japonicus (Wang et al, 2008); catalase, thioredoxin peroxidase and glutathione peroxidase in snails Haliotis discus discus (De Zoysa et al, 2010); a diverse set of antioxidant enzymes in mussels M. galloprovincialis and M. trossulus (Lockwood and Somero, 2011). We detected up-regulation of GST in L. saxatilis in this study, while thioredoxin peroxidase was regulated in the same species during acute salinity stress (Muraeva et al, 2016).…”

“…Based on the mean value of 9 (3 x 3) samplings, the expression of i-type lysozyme gene in C. hongkongensis increased through day 3 and then fell rapidly to almost 0 by day 5 at 34℃, which may be due to induce energy balance disequilibrium in C. hongkongensis. At the same time, high temperature could also cause oxidative stress and increase excessive production and accumulation of reactive oxygen species (ROS) [31], resulting in immunity reduction, cell damage, mutation, and even death [15], [32], [33]. Additionally, immune enzyme's structural stability could be affected by temperature in such a way that high temperature could change the protein's spatial structure by disintegrating the maintaining bonds and resulting in thermal denaturation [34].…”

Abstract:An experiment was conducted to analyze thei-type lysozyme cDNA cloned from oyster (Crassostrea hongkongensis) and study the effect of temperature on the gene expression in an indoor, controlled constant-temperature environment. The cDNA was 634 bp with a 420-bp open reading frame, encoding 139 amino acids. A new conserved amino acid sequence, HNGGPRGC, was found in the protein sequence of the i-type lysozyme from C. hongkongensis. Real-time quantitative PCR (RTQ-PCR) was used to assess the expression of the i-type lysozyme gene in the digestive gland, smooth muscle, gills, mantle and labial palps of C. hongkongensis. The expression was the highest in the digestive gland and the lowest in the muscle. A thermal stress experiment was performed to study the effect of temperature on the expression of the i-type lysozyme gene. The expression was stable when water temperature ranged from 20 0 C to 25 0 C. The level of expression tended to decrease at 6 0 C or 13 0 C. A conclusion was drawed that the variations in temperature affect i-type lysozyme gene and immune function of C. hongkongensis.
