Polyphenols in nutritions and their effect on DNA
Osorio, Juan ; Černayová, Diana (oponent) ; Brázda, Václav (vedoucí práce)
Epidemiological studies have shown the effect of plant-derived food consumption in the prevention of a wide range of diseases. The natural antioxidants present in these foods, among which polyphenols are very relevant, may be responsible for this health-promoting activity. The aim of this bachelor thesis is to submit evidence in the interaction of certain polyphenols with the genetic material through different signaling mechanisms, especially regarding the stabilization of the non-canonical DNA structure G-quadruplex and therefore point out the most selective substance to inhibit biochemical processes. Furthermore, the thesis includes detailed information that might help understand how polyphenol compounds can be attached to the DNA through epigenetic mechanisms and G4 structures, and which factors may affect the efficiency of these. Different experiments, by biological and experimental repetition, were used to corroborate the interaction between the compounds and DNA.
