Investigating the genomic and biochemical effects of dalapon on antioxidant systems in zebrafish, .

This research explored the effects of dalapon exposure on the expression of various genes, including , , , , , , , , , , , , , , and , along with the activities of related antioxidant enzymes (AEs), such as CAT, SOD, GPX, G6PD, GST, and GR in zebrafish. Kidney and liver tissues were analyzed to assess oxidative stress levels. Results indicated that both the concentration of dalapon (25 and 50 ppm) and the duration of exposure had a significant effect on AE activities and gene expression.

Genomic organization and transcription of superoxide dismutase genes (, , and ) and response to diazinon toxicity in platyfish () by using SOD enzyme activity.

The aim of this study is to determine the effects of 50% of 96 h LC (5.25 ppm) diazinon on the expression of superoxide dismutase (SOD) enzyme genes (, , and ) and SOD enzyme activity at the end of 24, 48, 72, and 96 h in platyfish liver and gill tissues. To this end, we determined the tissue-specific distribution of , , and genes and performed analyses in platyfish ().

Fatty acid-binding protein genes in gilthead seabream: molecular cloning and nutritional regulation under low water temperatures.

The molecular characteristics and tissue disruption of 10 fatty acid-binding protein (fabp) genes in gilthead seabream (Sparus aurata) were investigated, and their expression levels were found in the fish fed diets with different vegetable oil (VO) sources, which may explore the potential function of fabp genes in S. aurata. For this purpose, the open reading frames of fabp genes involved in the transport and ß-oxidation of fatty acids (FA) were molecularly cloned and characterized.

Molecular cloning and characterization of Cu-Zn superoxide dismutase () gene in brown trout and its expression in response to acute aquaculture stressors.

Aquaculture species are often exposed to acute stressors such as low water levels and handling during routine aquaculture procedures. This might result in oxidative stress by the increased reactive oxygen species (ROS)' production (, superoxide anion). The harmful effects of ROS are eliminated by a defense system, referred antioxidant defense system (ADS).

Identification and Characterization of Carnitine Palmitoyltransferase 1 () Genes in Nile Tilapia, .

Four genes (, and ) were identified in the Nile tilapia genome. Two transmembrane helix domains (TMH) were identified for Cpt 1α1a, Cpt 1α2a, and Cpt 1β, while Cpt 1α2b had only one TMH domain. Evidence was found of conserved gene synteny between genes from Nile tilapia and the genes of zebrafish and human.

Divergent spatial regulation of duplicated fatty acid-binding protein (fabp) genes in rainbow trout (Oncorhynchus mykiss).

The increased use of plant oil as a dietary supplement with the resultant high dietary lipid loads challenges the lipid transport, metabolism and storage mechanisms in economically important aquaculture species, such as rainbow trout. Fatty acid-binding proteins (Fabp), ubiquitous in tissues highly active in fatty acid metabolism, participate in lipid uptake and transport, and overall lipid homeostasis. In the present study, searches of nucleotide sequence databases identified mRNA transcripts coded by 14 different fatty acid-binding protein (fabp) genes in rainbow trout (Oncorhynchus mykiss), which include the complete minimal suite of seven distinct fabp genes (fabp1, 2, 3, 6, 7, 10 and 11) discovered thus far in teleost fishes.

Alterations in fatty acids of polar lipids in Salmo trutta on long-term exposure to a glyphosate-based herbicide (Roundup).

Abstract: In present study, the effects of sublethal doses (10 and 20 mg L(-1)) of Roundup on fatty acid pattern in muscle and liver of brown trout were investigated. For this purpose, fish were held in experiment tanks for 1 month. While total MUFA wasn't influenced, the highest total SFA and total n-6 PUFA were determined in group 10 mg L(-1) and the lowest values were determined in control group and group 20 mg L(-1) in muscle, respectively.

Goose fat, a promising nutrient for fish feeding, activates antioxidant enzymes in rainbow trout, Oncorhynchus mykiss.

The objective of this experiment was to test effects of different dietary lipids in rainbow trout feeding on the activity and expression of antioxidant enzymes, superoxide dismutase (SOD), glutathione peroxidase (GPx) and glutathione S-transferase (GST). Four iso-nitrogenous and iso-lipidic casein-gelatin based experimental diets were formulated. The sources of dietary lipids were cod liver oil (CO, rich in polyunsaturated fatty acids), goose fat (GF, rich in saturated fatty acids and monounsaturated fatty acids), soybean oil (SO, rich in linoleic acid), and a blend of CO, GF and SO.

Metabolic responses to prolonged starvation, food restriction, and refeeding in the brown trout, Salmo trutta: oxidative stress and antioxidant defenses.

The effects of long-term starvation and food restriction (49 days), followed by refeeding (21 days) have been studied with respect to antioxidant defense in the liver and gills (branchial tissues) of the brown trout, Salmo trutta. Malondialdehyde levels in both tissues increased in parallel with starvation and food restriction and these values did not return to normal after the refeeding period. The activities of superoxide dismutase (SOD), catalase (CAT), glutathione peroxidase (GPx), and glutathione reductase (GR) in liver and gills increased during the 49 days of starvation, but glucose-6-phosphate dehydrogenase (G6PD) activities decreased.
