Research Description
Our laboratory is studying the role of the enzyme cyclooxygenase in the regulation of intestinal epithelial cell growth and transformation. Cyclooxygenase (COX), a key enzyme in the prostaglandin biosynthetic pathway, is transcribed from two distinct genes, COX- I and COX-2. COX-2 is also a member of a family of genes called "immediate early" or "early growth response" genes, and many immediate early genes have been found to be proto-oncogenes like c-fos and c-jun. Likewise, COX-2 is thought to play an important role in the development of intestinal neoplasms.

We have demonstrated that COX-2 expression is markedly increased in 85-90% of human colorectal adenocarcinomas as well as in two rodent models of colorectal carcinogenesis. Interestingly, several epidemiological studies have reported a 40-50% reduction in the risk of developing colorectal cancer in persons who take non-steroidal anti-inflammatory drugs (NSAIDs), such as aspirin, which are classic inhibitors of cyclooxygenase. These results suggest that COX-2 contributes to the development of intestinal tumors, and this hypothesis is supported by the demonstration that mice null for COX-2 have an 86% reduction in tumor multiplicity in a background containing a mutation in the tumor suppressor gene, APC.

Using zebrafish we have found an important role of COX-1 in early kidney development and in vasculogenesis. We are exploring this model to understand the role of eicosanoid signaling in organogenesis and are attempting to develop a fish model of intestinal cancer.

We are continuing to investigate the role that COX is playing in the regulation of epithelial cell growth and tumorigenesis. Recent studies indicate that COX-1, as well as COX-2, are playing an important role in tumorigenesis through effects on cell proliferation as well as angiogenesis and our long term goal is to understand the downstream signaling pathways through which these processes are regulated. We have recently discovered several novel targets for cancer prevention and treatment using this approach. One of these includes the PPARdelta nuclear receptor. We have also found that prostaglandin signaling indirectly activates the EGFR pathway and that targeting both pathways may be much more effective. Pre-clinical studies are underway to determine the potential role of these targets for new cancer treatment options.
