Doctoral Dissertations

The main purpose of this study was to investigate the possible mechanism(s) of L-carnitine-mediated modulation of AFB₁-DNA adducts formation. The first part of the study investigated the effect of increased doses of carnitine on AFB₁ binding to macromolecules, AFB₁ uptake, activity of glutathione S-transferase (GST), and total glutathione concentrations in freshly isolated hepatocytes. Carnitine dose was significantly correlated with the formation of AFB₁-DNA adduct ( r = -0.68;p = 0.0002 ), AFB₁-protein adduct (r = 0.58;p = 0.017), but not AFB₁-RNA adduct (r = 0.14;p = 0.604). …
