Cichoric acid attenuates the toxicity of mesotrione. Effect on in vitro skin cell model.

ABSTRACT

There is an important need to increase knowledge regarding the interactions between environmental contaminants and other compounds. Pesticides are an important group of food contaminants. By contrast, cichoric acid (CA) belongs to the category of desirable food ingredients with antioxidant and cytotoxic effects. The aim of the presented study was to test if CA may constitute a food ingredient, which eliminate stimulatory effect of pesticides on skin cancer cells and toxic effect of herbicides on fibroblasts. Therefore, we conducted cytotoxicity studies of environmentally relevant pesticide concentrations and the mixture of both compounds in melanoma and fibroblasts cells. We studied if CA combined with mesotrione change the oxidative stress parameters and apoptotic activity in treated cells. Obtained results indicate that CA exhibits cytotoxic activity against mesotrione-induced skin cancer development by influencing oxidative stress parameters and apoptosis. On the other hand CA inhibits prooxidative and proapoptotic activity of mesotrione in fibroblasts. Presented methods and obtained results could be a useful tool in the analysis of environmental contaminants toxicity and possible preventive activity of antioxidative plant- origin compounds.
