Abstract
Tumor development consists of several separate, but closely linked, stages: tumor initiation, promotion, and progression. This long and complex process provides opportunities for intervention both in preventing cancer initiation and in treating the neoplasm during its premalignant stages. Resveratrol, a polyphenolic compound found in many plant species, including grapes, peanuts, and various herbs, has recently been investigated intensely for its cancer chemopreventive property. The present work is an overview of the chemopreventive mechanisms of resveratrol in antiโinitiation, antiโpromotion, and antiโprogression. These, together with the low toxicity of resveratrol, suggest promise for novel chemopreventive agents. However, the low bioavailability and rapid clearance of resveratrol from the circulation require the design of new resveratrolโlike chemopreventive agents, the structural modifications and the structureโactivity relationship of which are also discussed in this review.

Experimental studies have demonstrated that carcinogenesis is a multistep process in which inappropriate proliferation of cells is a critical determinant. Polyamines support sustained growth and are highly regulated in all cells. The rate limiting enzyme for this pathway is ornithine decarboxylase (
Here we develop a rapid, cell-based, functional assay to screen and identify naturally occurring or synthetic chemicals with chemopreventive activity. We constructed a reporter gene that consists of the geneencoding green fluorescent protein (GFP) under the transcriptional control of the thymidine k
Cancer chemoprevention is concerned with the development of drugs or diet supplements that will avert the onset or stop the progression of the intraepithelial neoplasia which precedes invasive cancer. Two basic processes underlie the onset and development of intraepithelial neoplasia. First is genom
