Abstract

A large number of investigations have demonstrated a broad spectrum of pharmacological and therapeutic benefits of grape seed proanthocyanidins (GSP) against oxidative stress and degenerative diseases including cardiovascular dysfunctions, acute and chronic stress, gastrointestinal distress, neurological disorders, pancreatitis, various stages of neoplastic processes and carcinogenesis including detoxification of carcinogenic metabolites. GSP exhibited potent free radical scavenging abilities in both in vitro and in vivo models. GSP exerted significant in vivo protection against structurally diverse drug and chemical-induced hepatotoxicity, cardiotoxicity, neurotoxicity, nephrotoxicity and spleentoxicity. GSP also protected against idarubicin and 4-hydroxyperoxy-cyclophosphamide-induced cytotoxicity toward human normal liver cells. GSP exhibited selective cytotoxicity toward selected human cancer cells, while enhancing the growth and viability of normal cells. GSP exhibited potent modulatory effects of pro-apoptotic and apoptotic regulatory bcl-XL, p53, c-myc, c-JUN, JNK-1 and CD36 genes. Long-term exposure to GSP may serve as a novel chemoprotectant against three stages of DMN-induced liver carcinogenesis and tumorigenesis including initiation, promotion and progression. GSP may selectively protect against oxidative stress, genomic integrity and cell death patterns in vivo. These results demonstrate that GSP may serve as a novel therapeutic intervention against carcinogenesis.
