Farnesol alleviates diethyl nitrosamine induced inflammation and protects experimental rat hepatocellular carcinoma.

Abstract

Hepatocellular carcinoma is a well-known internal malignancy with increased worldwide mortality. The increased progression rate is closely associated with chronic liver diseases such as cirrhosis. Chemical carcinogens cause tumor advocacy over free radical metabolites to causes numerous biochemical and molecular changes that bring oxidative stress. In addition, inflammatory cells and its growth factor promotes the progression of liver cancer through deregulates the numerous cellular signaling pathways involved in normal cellular proliferation. Plant derived phytochemicals have a better complimentary potency to defend against a wide array of free radical mediated diseases such as cancer. More recently, we have evaluated the anticancer effect of Farnesol against DEN induced hepatocellular carcinoma in male wistar albino rats. However, the possible mechanism in which Farnesol attributes its anticancer effect against DEN induced liver cancer remains unknown. Hence in the present study, an attempt has been made to reduce the oxidative stress by appraise the antioxidant effect by Farnesol in DEN induced hepatocellular carcinoma. Elevated oxidative stress markers with concomitant decreased cellular antioxidants levels were observed in DEN induced hepatic tissues. Further, proliferating nuclei with increased proliferating cell nucleolar antigen (PCNA) and inflammatory mediator expression were observed in DEN induced rats. Oral supplementation of Farnesol to DEN induced rats significantly decrease the oxidative stress markers and increase the cellular antioxidant status. Moreover, Farnesol treatment decreases the argyrophilic nuclear organizer region and PCNA along with decreased expression of inflammatory mediators suggest that Farnesol treatment restores DEN induced hepatic abnormalities and protects liver from cancer progression.
