Highly expressed genes in rapidly proliferating tumor cells as new targets for colorectal cancer treatment

Abstract

Purpose: The clinical management of colorectal cancer patients has significantly improved because of the identification of novel therapeutic targets such as EGFR and VEGF. Because rapid tumor proliferation is associated with poor patient prognosis, here we characterized the transcriptional signature of rapidly proliferating colorectal cancer cells in an attempt to identify novel candidate therapeutic targets. Experimental Design: The doubling time of 52 colorectal cancer cell lines was determined and genome-wide expression profiling of a subset of these lines was assessed by microarray analysis. We then investigated the potential of genes highly expressed in cancer cells with faster growth a..
