Possible Protective Potency of Argun Nut (Medemia argun - An Ancient Egyptian Palm) against Hepatocellular Carcinoma in Rats.

Abstract

IntroductionHepatocellular carcinoma (HCC) is one of the most common cancers worldwide. Medemia argun (MA) fruits have been found to possess proanthocyanidins (PACs), having antioxidant activity. Methods: Intraperitoneal (IP) diethyl nitrosamine (DENA; 200 mg/kg, once) and carbon tetra chloride (CCl4, 3 ml/kg/week, subcutaneously, for 6 weeks) induced HCC in rats. Animals groups: Group I; received vehicle (control). Group II; received MA seed extract, 100 mg/kg (twice/week) for 12 weeks, IP. Group III; received carcinogenic agents only. Group IV; received MA for two weeks before administration of DENA/CCl4 till the end of the experiment. The total period of the experiment was three months. Results: DENA and CCl4 induced HCC, elevated serum alpha-fetoprotein (AFP), liver size, weight, tissue lymphocytic infiltration, nuclear/cytoplasmic ratio, collagen fiber and polysaccharide deposition, cellular proliferation, excessive pro-apoptotic caspase-3 accumulation, disrupted apoptosis. MA prior to DENA/CCl4, significantly protected liver against cancer progression, indicated by serum enzymes, antioxidant markers(glutathione, nitric oxide, and depressed malondialdehyde contents) in the MA-pretreated group, compared to the HCC one, without apparent useful action on superoxide dismutase activity, enhanced apoptosis in liver, through increased casapase-3 expression. The HCC group showed decreased antioxidant defense and BAX/Bcl-2 ratio. Conclusions: This study assumes that MA has a chemo-preventive effect against hepatocarcinogenesis.
