Abstract

Ginger has been proposed as quite a promising candidate for cancer prevention. The purpose of this study was to assess the chemo-preventive effects of ginger. Furthermore, this study investigated the possible mechanisms of a standardized extract drawn from the rhizomes of ginger against diethylnitrosamine (DEN)-induced liver cancer in Wistar rats. The chemo-preventive effects of ginger at doses of 75 mg/kg, 150 mg/kg and 300 mg/kg per day were determined using a liver cancer model which was induced by DEN (Ali et al., 2008) and 2-acetylaminofluorene (2-AAF) in rats. Ginger attenuated carcinogenic changes after 22 weeks of cancer induction by decreasing the quantity and occurrences of hepatic dyschromatic nodules and positive focal areas as well as decreasing the amount of placental glutathione S-transferase (GST) in the livers of DEN/2-AAF-treated rats. Moreover, in rats, ginger counteracts DEN-influenced oxidative stress and decreases myeloperoxidase, malondialdehyde and protein carbonyl concentrations in the liver. This was determined by observing the restoration of superoxide dismutase, catalase, GST and glutathione. Immunohistochemical bleaching in rat livers showed that ginger prevented the increase in cell-positive numbers for Ki-67, cyclooxygenase-2 and nuclear factor kappa B p65. Ginger also inhibited the number of positive cells in DEN/2-AAF-treated rats for TUNEL, M30 and caspase-3 liver tissues. This research shows that ginger has an important chemo-preventative impact on liver cancer by inhibiting the growth of cells and inducing apoptosis. By reducing oxidative and inflammatory damage, ginger protects rat liver against cancer.
