Among these is the isothiocyanate class of chemicals present in cruciferous vegetables such as broccoli.\u00a0 Isothiocyanates have been well characterized for their activity in preventing tumor development in carcinogen-challenged animals. However, little is know about how these compounds prevent cancer, and whether they may have other beneficial health effects.<\/p>\n<p>The bioactive nutrient isothiocyanates (ITCs) are chemically reactive compounds whose structure suggests that they could covalently modify potential protein targets. Using a novel proteomics screen, we identified a prevalent protein target of ITC modification in the cell.\u00a0 This protein is implicated in the pathogenesis of a number of inflammatory diseases including rheumatoid arthritis, inflammatory bowel disease and asthma where studies have shown that it is a critical participant in the disease process.\u00a0 As a participant in signal transduction, gene expression, apoptosis and proliferation of target cells, this protein is a provocative molecular target for the isothiocyanates that could explain their chemopreventive activity.\u00a0 In addition, the central role of this protein in inflammatory disease processes may indicate a potential anti-inflammatory benefit for these nutrient compounds.<\/p>\n<p>Using two of the most prevalent isothiocyanates in broccoli, sulforaphane and PEITC, we are working to characterize the importance of this protein target in the phenomenon of cancer chemoprevention.\u00a0 In addition, we are using both in vitro studies and animal models to characterize the potential of these compounds to interfere with inflammatory processes in an intact organism.\u00a0 These studies may define a molecular mechanism for action of cancer chemopreventives and allow the development of alternative approaches for cancer prevention.\u00a0 Moreoever, they may provide additional insights into the well-appreciated epidemiological link between inflammation and cancer risk and define a pharmacological target for intervention in these processes.<\/p>\n<h4>Publications<\/h4>\n<ul>\n<li>\u00a0Villarreal-Calderon R, Lu\u00c3\u00a9vano-Gonz\u00c3\u00a1lez A, Arag\u00c3\u00b3n-Flores M, Zhu H, Yuan Y, Xiang Q, Yan B, Stoll KA,\u00a0<strong>Cross JV<\/strong>, Iczkowski KA, Mackinnon AC: Antral atrophy, intestinal metaplasia, and preneoplastic markers in Mexican children with Helicobacter pylori-positive and Helicobacter pylori-negative gastritis.
