Effect of curcumin on the embryotoxic effect of ethanol in a zebrafish model

Curcumin, a natural polyphenol found in the turmeric plant, has been shown to have anti-inflammatory and antioxidant properties. It has been widely studied for its potential protective effect against various health conditions, including ethanol-induced malformation. Ethanol exposure during pregnancy can lead to various developmental abnormalities, known as fetal alcohol syndrome (FAS) and fetal alcohol spectrum disorders (FASD). Due to the high prevalence of FASD and FAS and no effective treatment, it is essential to develop preventive strategies. Recent studies have investigated the potential protective effect of curcumin against ethanol-induced malformation in animal models. This study aimed to examine whether curcumin can reduce the toxic effects of ethanol in zebrafish embryos. The present study showed that pure curcumin applied together with 1.5 % ethanol (v/v) did not lead to a protective effect on ethanol-induced malformations such as disturbances of body length and width or pericardia oedema in growing zebrafish embryos. Moreover, curcumin extract showed a pro-oxidant effect in the Fenton reaction in the presence of ethanol.
