Abstract
Hepatocellular carcinoma (HCC) is one of the ten most commonly diagnosed cancers. Doxorubicin is an antibiotic used in cancer treatment protocols that has several side effects. L-Arginine is a non-essential amino acid that is used as immune system activation and antitumor drugs. Therefore, the current study was designed to compare using doxorubicin, L-arginine, or their combination as a prophylactic agent against hepatic carcinoma induced by hepatocellular carcinoma cells (HepG2) injection in mice. The mice were divided into five groups: normal mice and mice that received HepG2, doxorubicin and HepG2, L-arginine and HepG2, and doxorubicin, L-Arginine, and HepG2, respectively. Liver function test as, aspartate transaminase (AST) and alanine transaminase (ALT), and alpha-fetoprotein (AFP), caspase 3, interleukin 6 (IL-6), tumor necrotic factor (TNF), lipid peroxidation (NDA), and some antioxidant parameters were determined. A significant increase in AST and ALT, α-fetoprotein, TNF-α, and cytokines IL6 and MDA and a significant decrease in the serum caspase and liver catalase were determined in HepG2-injected mice. Moreover, some large hyperchromatic heptocytes were observed and the percentage of the positive area/field of HepPar-1, the most specific HCC marker, was 9.56%. Interestingly, mice that received doxorubicin, L-arginine, or their combination showed an improvement in some of the previous parameters. The improvement was more prominent with L-arginine administration.
