The primary research objective of this laboratory is to determine the mechanism of action and chemotherapeutic potential of novel agents that are derived from natural sources (plants, animals, and minerals). We are currently interested in examining the activity of cannabinoids and bioflavonoids.

Cannabinoids are a class of compounds that bind to and activate the prototypic cannabinoid receptors, CB1 and CB2.The cannabinoids are derived from plant material [phytocannabinoids, e.g. Δ9-tetrahydrocannabinol (Δ9THC)], animals [endocannabinoids, e.g. arachidonoyl ethanolamide (AEA)], or are synthesized (e.g. WIN55,212-2). Our specific goal is to examine the chemotherapeutic activity of the endocannabinoid, AEA. We have determined that AEA and its metabolic product, 15deoxy,Δ12,14PGJ2-EA, selectively induce death in tumorigenic keratinocytes while causing little harm to non-tumor keratinocytes. Current research in our laboratory is focused on detailing the mechanism of action and determining the in vivo activity of these agents using experimental techniques in the fields of molecular biology, chemistry, pharmacokinetics, and tumor biology.

Another objective of our research is to understand the molecular events involved in apigenin-mediated prevention of skin cancer. Apigenin is a bioflavonoid that is present in fruits, leafy green vegetables and teas. Several studies demonstrate that apigenin inhibits tumorigenesis in various organ systems. COX-2 is an enzyme that promotes tumor growth and is overexpressed in cancers including colon, prostate, breast, lung and skin. Our studies suggest that apigenin prevents skin tumorigenesis by inhibiting cyclooxygenase-2 (COX-2). Research in our laboratory seeks to examine the role of COX-2 and other cellular proteins in the in vitro and in vivo antitumor activity of apigenin.
