Core Tip

Core tip: Review compares the available evidence on the chemopreventive efficacy and probable mechanisms of chemoprevention by selected dietary phytochemicals in experimental systems and clinical trials. All the dietary phytochemicals covered have demonstrated chemopreventive efficacy against carcinogen-induced tumors in rodents at several organ sites. Mechanism of observed chemopreventive action(s) involve phytochemical-mediated redox changes, modulation of enzymes and signaling kinases leading to effects on multiple genes and cell signaling pathways. Clinical trials with these compounds have not demonstrated their chemopreventive efficacy. Probable reasons for observed mismatch between the two systems and areas of current research efforts and recommendations have been presented.
