ABSTRACT
INTRODUCTION:
2-AAF and DEN are well-known liver toxicants commonly used to stimulate tumors in laboratory animals.AIM:
The aim of this study was to investigate the effect of octreotide on DEN-induced and 2-AAF-supplemented hepatocarcinogenesis in Wistar albino rats. MATERIALS ANDMETHODS:
In this study, 64 Wistar albino rats were divided into 8 groups. DEN (175 mg/kg) initiated and 2-AAF (20 mg/kg) promoted liver carcinogenesis in rats. The tumor growth inhibitor octreotide (300 µg/kg) was used. Rats were sacrificed at the end of experiment and their liver tissues were taken for the study. SOD, GSH-Px, CAT activities, NO and MDA levels were measured spectrophotometrically. Also, Hsp70 and 8-OHdG was measured by the ELISA method.RESULTS:
In group 7, MDA, 8-OHdG, and Hsp70 levels were significantly increased. In addition, SOD, GSH-Px activity was significantly reduced in this group. MDA, 8-OHdG and Hsp70 levels were significantly reduced in Group 8, which received octreotide for treatment.CONCLUSION:
DEN and 2-AAF cause very serious liver damage. Octreotide protects the liver from carcinogenesis, increases the activity of cellular antioxidant enzymes and helps reduce DNA damage. Therefore, octreotide may be an inhibitor in tumor cells and may reduce oxidative stress.Key words
