Figure 1. Green tea for the chemoprevention of hepatocellular carcinoma.
Gamma-hydroxy-1,N2-propanodeoxyguanosine (γ-OHPdG), a mutagenic lipid peroxidation-induced DNA adduct correlates with hepatocellular carcinoma (HCC) incidence in experimental murine models of HCC. Theaphenon E administration reduced the HCC tumor burden and γ-OHPdG levels, suggesting that the chemopreventive effect of green tea might be mediated by Theaphenon E by decreasing γ-OHPdG in liver DNA and consequent DNA mutations
