Quercetin is an antioxidant flavonoid, found ubiquitously in nature and extensively used in herbal medicines and food additives. This study aimed to investigate the effect of quercetin on diethylnitrosamine-induced preneoplastic lesions, using the medium-term rat liver bioassay. The ?-benzene hexachloride was used as promoter at the doses of 0.1, 1.0, and 10.0 mg/kg against a single dose of diethylnitrosamine (200 mg/kg) in male Sprague-Dawley rats. All the rats were subjected to 70% partial hepatectomy at Week 4. The protective effect of quercetin (5 and 25 mg/kg) was examined against the highest dose of ?-benzene hexachloride (10 mg/kg). A significant increase in the number as well as the mean area of glutathione S-transferase placental form (GST-P) positive foci, p53 positive hepatocytes, and the percentage of apoptotic cells were observed in the diethylnitrosamine-treated group. In the present investigation, both doses of QC (5 and 25 mg/kg) led to a significant decrease in the number as well as the mean area of GST-P positive foci, TUNEL positive apoptotic cells, p53 positive hepatocytes, and restoration of cellular morphology. These results clearly indicate that quercetin inhibits diethylnitrosamine-induced hepatic preneoplastic lesions in medium-term rat liver bioassay.
