“…In line with this, some studies showed an increase in the activity in gills of mussels M. galloprovincialis exposed to benzo(a)pyrene (10 lg L À1 ) at seven days (Maria and Bebianno, 2011) or when collected from field areas contaminated with petroleum derivatives (Lima et al, 2007). Moreover, oysters Crassostrea gigas exposed to diesel at 1 mL L À1 and 0.1 mL L À1 showed elevated GST activity in gills (Zanette et al, 2011). Contrarily, in our study, after 48 h exposed to the lowest concentration of B5, the GST activity was decreased in gills when compared to the control group, which could be related to the presence of chemical elements in B5 that might inhibit the enzyme.…”

“…Other than aminotransferases, abundant genes under the term of “transferase activity” are significantly enriched in up-regulated genes, which are mainly comprised of “transferring one-carbon groups”, “transferring acyl groups”, “transferring glycosyl groups”, “transferring phosphorus-containing groups”, suggesting their important roles in response to environmental stress in AW. One of well-studied transferase families is glutathione S-transferase (GST) gene family, which have been confirmed their essential functions in protection against oxidative stress caused by various stress from toxic heavy metal ions [39-41], osmotic imbalance [42], salinity [43] and pH change [44]. GSTs have been even used as biomarkers for environmental pollution and toxins monitoring recently [45,46].…”

BackgroundAmur ide (Leuciscus waleckii) is an economically and ecologically important cyprinid species in Northern Asia. The Dali Nor population living in the soda lake Dali Nor can adapt the extremely high alkalinity, providing us a valuable material to understand the adaptation mechanism against extreme environmental stress in teleost.ResultsIn this study, we generated high-throughput RNA-Seq data from three tissues gill, liver and kidney of L. waleckii living in the soda lake Dali Nor and the fresh water lake Ganggeng Nor, then performed parallel comparisons of three tissues. Our results showed that out of assembled 64,603 transcript contigs, 28,391 contigs had been assigned with a known function, corresponding to 20,371 unique protein accessions. We found 477, 2,761 and 3,376 differentially expressed genes (DEGs) in the gill, kidney, and liver, respectively, of Dali Nor population compared to Ganggeng Nor population with FDR ≤ 0.01and fold-change ≥ 2. Further analysis revealed that well-known functional categories of genes and signaling pathway, which are associated with stress response and extreme environment adaptation, have been significantly enriched, including the functional categories of “response to stimulus”, “transferase activity”, “transporter activity” and “oxidoreductase activity”, and signaling pathways of “mTOR signaling”, “EIF2 signaling”, “superpathway of cholesterol biosynthesis”. We also identified significantly DEGs encoding important modulators on stress adaptation and tolerance, including carbonic anhydrases, heat shock proteins, superoxide dismutase, glutathione S-transferases, aminopeptidase N, and aminotransferases.ConclusionsOverall, this study demonstrated that transcriptome changes in L. waleckii played a role in adaptation to complicated environmental stress in the highly alkalized Dali Nor lake. The results set a foundation for further analyses on alkaline-responsive candidate genes, which help us understand teleost adaptation under extreme environmental stress and ultimately benefit future breeding for alkaline-tolerant fish strains.

“…and ED-17.88 groups at that time. Support for this inference is found in several recent studies (Gan et al, 2016;Liao et al, 2012;Zanette et al, 2011), in which MDA content increased under salinity stress, but low MDA content was observed in fish with a strong antioxidant ability.…”

Fatty acid composition, osmolality, Na ⁺ , K ⁺ ‐ATPase activity, cortisol content and antioxidant status of rainbow trout ( Oncorhynchus mykiss ) in response to various dietary levels of eicosapentaenoic acid and docosahexaenoic acid

This study was conducted to evaluate the effect of dietary eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) levels on the fatty acid composition, salinity tolerance and antioxidant status of rainbow trout (Oncorhynchus mykiss). Four diets were formulated with total EPA and DHA contents of 5. 41, 9.55, 13.97 and 17.88 g/ kg (abbreviated as ED-5.41, ED-9.55, ED-13.97 and ED-17.88 respectively). Rainbow trout (initial weight of 90.61 ± 9.25 g) were fed the experimental diets for 8 weeks to accumulate significant differences in fatty acid composition and subsequently underwent salinity acclimation. Our results indicated that high dietary EPA and DHA significantly improved the EPA and DHA content in fish tissues. The serum osmolality of fish returned to their freshwater values in the ED-9.55, ED-13.97 and ED-17.88 groups. The Na + , K + -ATPase (NKA) activity of fish in the ED-13.97 group changed dramatically to adapt the fish to the hypertonic environment. Moreover, there was no significant difference in the serum cortisol concentration and liver catalase (CAT) activity of fish in the ED-13.97 group during salinity acclimation. The liver superoxide dismutase (SOD) activity in the ED-13.97 group was significantly higher than that in ED-5.41 and ED-9.55 groups at the end of salinity acclimation. The muscle malondialdehyde (MDA) content in the ED-13.97 group was significantly lower than that in the ED-17.88 group before salinity acclimation and significantly lower than the ED-5.41 and ED-17.88 groups on day 7 of acclimation. The results of this study indicate that the rainbow trout in the ED-13.97 group exhibited optimal salinity acclimation performance.
