چکیده

Basic Violet 14, Direct Red 28 and Acid Red 26 are classified as carcinogenic dyes in the European textile ecology standard, despite insufficient toxicity data. In this study, the toxicity of these dyes was assessed in a zebrafish model, and the underlying toxic mechanisms were investigated. Basic Violet 14 and Direct Red 28 showed acute toxicity with a LC50 value at 60.63 and 476.84 µg ml(-1) , respectively, whereas the LC50 of Acid Red 26 was between 2500 and 2800 µg ml(-1) . Treatment with Basic Violet 14, Direct Red 28 and Acid Red 26 resulted in common developmental abnormalities including delayed yolk sac absorption and swimming bladder deflation. Hepatotoxicity was observed in zebrafish treated with Basic Violet 14, and cardiovascular toxicity was found in zebrafish treated with Acid Red 26 at concentrations higher than 2500 µg ml(-1) . Basic Violet 14 also caused significant up-regulation of GCLC gene expression in a dose-dependent manner whereas Acid Red 26 induced significant up-regulation of NKX2.5 and down-regulation of GATA4 at a high concentration in a dose-dependent manner. These results suggest that Basic Violet 14, Direct Red 28 and Acid Red 26 induce developmental and organ-specific toxicity, and oxidative stress may play a role in the hepatotoxicity of Basic Violet 14, the suppressed GATA4 expression may have a relation to the cardiovascular toxicity of Acid Red 26.

Effect of lighting conditions on zebrafish growth and development.

In the underwater environment, the properties of light (intensity and spectrum) change rapidly with depth and water quality. In this article, we have described how and to what extent lighting conditions can influence the development, growth, and survival of zebrafish. Fertilized eggs and the corresponding larvae were exposed to different visible light wavelengths (violet, blue, green, yellow, r...

The Anti-melanogenesis Activities of Some Selected Red Macroalgae from Northern Coasts of the Persian Gulf

Tyrosinase is a key enzyme in melanin production. Therefore, tyrosinase inhibitors are used in cosmetic and medicinal industries to prevent or treat overproduction of melanin such as melasma, solar lentigo and post inflammatory melanoderma. Due to safety of natural whitening agents, in the present study, in-vitro anti-tyrosinase and in-vivo anti-melanogenesis activities of some selected red mac...

Bioaccumulation of Synthetic Dyes by Candida tropicalis Growing in Sugarcane Bagasse Extract Medium

Bioaccumulation of synthetic dyes viz. Acid Blue 93, Direct Red 28 and Basic Violet 3 by the environmental yeast isolate, Candida tropicalis growing in aqueous extract of sugarcane bagasse medium was studied in a batch system as a function of initial pH and dye concentrations. The optimum pH value for bioaccumulation was found to be 3.0 for Acid Blue 93 and Direct Red 28 and 5.0 for Basic Viole...

Identification of the first Transgenic Aquatic Animal in Iran by PCR-Based Method and Protein Analysis

In the recent years, there is evidence of training a red type of zebrafish which differs from wild-type in body color. There is not any document how it reaches to the ornamental fish farms of Iran but at first, it was a doubt it belongs to a morphotype or genetic modification (GM). First of all, a set primer was designed to validate zebrafish species. Mitochondrial 16srDNA was selected and ampl...
