Antioxidant and immune gene expression in zebra fish (Danio rerio)
Authors
Abstract:
Iodine is the main ingredient produced by the thyroid hormone, which playa a central role in the metabolism and the immune system. The present study aims to evaluate the effects of feeding Artemia fransiscana enriched with potassium iodide on antioxidant and immune gene expression in zebra fish (Danio rerio). Zebra larvae with an average weight of 2±0.01 mg were randomly distributed into 4 treatments with 3 replicates. The treatments were larvae fed 0.2, 0.5 and 1 mg/L potassium iodide enriched Artemia for 2 months. Result showed that potassium iodide significantly (P≤0.05) increased antioxidant and immune gene expression in zebra fish and the intensity of changes followed a dose- dependent manner. The 1 mg/L potassium iodide treated fish showed the highest gene expression in all studied genes. Due to changes in the expression of immune and antioxidant related genes, it appeared that potassium iodide could improve immune and antioxidant function in zebrafish.

Effect of TiO2 nanoparticles on the acute toxicity of Ag nanoparticles in zebra fish (Danio rerio)
The potential entry of nanomaterials into the water ecosystems increased following their increasing use. In addition to the direct effects of nanomaterials on aquatic organisms, they also affect the toxicity of other pollutants on aquatic organisms. This study assessed the presence of titanium dioxide nanoparticles (nTiO2) in water on acute toxicity of silver nanoparticles (AgNPs) on zebra fish...

Formalin is an effective solution for surface and equipment disinfection and also for several aquaculture industry challenge. Since various aquatics have different sensitivity to this substance, determination of a precise concentration for cultured fish is important. Because of diversity in aquarium fish species, this topic more highlights. In this study, the method of The Organisation for Econ...

The aim of the present study was to evaluate the effects of different levels of prebiotic on growth performance and non-specific immune parameters of zebra fish. Four hundred and twenty fish (mean weight 45 ± 0.1 mg) were supplied, randomly stocked in aquaria assigned to four treatments repeated in triplicates and fed with experimental diets contain 0, 0.5, 1 and 2% prebiotic for 8 weeks. At th...

Arsenic, an important environmental contaminant, is present in the aquatic environment as a result of geogenic and anthropogenic processes (Gonzaliz et al., 2006; Singh and Banerjee, 2008) and it has been reported as one of the most alarming chemical (ATSDR, 2002). In the environment, arsenic is present in different forms and the toxicity depends upon its chemical form and oxidation states (Agu...

The protein sequence of insulin of zebra fish is obtained from UniProt. Due to lack of their structure, structure prediction is necessary, because the structure of protein plays an important role in their function. Our work is based on the production of two protein structure, from the same sequence, by computational approach and finally validates these generated structures. In this work two dif...

The need of aquarists for proper and safe disinfection of fish with Chloramine-T (CL-T) necessitates toxico/pathologic examinations. This study assays toxicity level of CL-T and histopathologic changes of gills, liver, kidney and brain of treated zebrafish (Danio rerio). Groups of 10 Zebrafish were treated with 0 (control), 5, 10, 15, 30, 50,100 and 200 mg/L of CL– T. Mortality was recorded a...
