Colorectal Cancer Microarray Research Welcome to the Princeton University Gene Expression Project, a study in the lab of Dr. Daniel Notterman using microarrays to elucidate the molecular mechanisms of colorectal cancer. Several genes relevant to the pathogenesis of adenomas and carcinomas of the colon have been identified. Software will soon be available on this site to analyze expression data of your own. The site is optimized for frames users, but can be accessed with a frames incapable browser. Follow one of the links below to begin.
