Project Title:
Nutrigenomic effects of Indicaxantin in cell lines: mechanism of action and its influence on gene expression
Nutrigenomics is an emerging science which aims to identify and study the diet molecules having influence on beginning of some diseases and to characterize their possible mechanisms of action. In particular it intends to understand the nutrient-genome interaction, how diet molecules are able to interfere with DNA.
Phytochemicals are biologically active molecules in vegetables and are an highly inhomogeneous cluster of substances with protective effects on human health. Phytochemical Indicaxantin, in particular, is a yellow pigment contained in the mediterranean plant Opunzia ficus indica fruit.
It was recently demonstrated that indicaxantin have antioxidant properties, E vitamin-like and it was also demonstrated that pathogenesis of alcohol-consumption diseases is similar to an inflammatory process (Weise JG et al. 2000). Some phytochemical are able to modulate gene expression of metabolizing enzymes, like CYP2E1 for example, and, Opunzia ficus indica fruit-extract reduces symptoms of acute alcohol consumption (Wiese JG et al. 2004).
Nothing, unfortunately, was reported about cause/effect relation between indicaxantin and expression modulation of xeno-methabilizing genes, so, it could be more interesting to clarify the gene-regulating role of indicaxantin, by the understanding of its mechanism of action.
In conclusion the present project aim to evaluate nutrigenomic properties of indicaxantin in hepatic and non-hepatic cell lines to understand its protective mechanisms, taking also into consideration a role of direct or indirect gene expression regulator.
Results from this project could give the basis for probable future use of indicaxantin in phytotherapy.
