A critical serine phosphorylation site at amino acid 37 that ordinarily targets ß-catenin for degradation has been mutated (10) . Fig. 1D. Citation illustrates a linear dose response to the effects of ß-cateninS37A. The peak response was observed when 1.25 µg of expression vector was cotransfected with 0.75 µg of reporter vector, resulting in a >30-fold stimulation of VEGF promoter activity. In independent studies, HeLa cells were treated with 25 mM LiCl, an inhibitor of GSK-3ß kinase activity. GSK-3ß is a negative regulator of Wnt signaling, and inhibiting GSK-3ß with LiCl resulted in a 2.2-fold increase in VEGF promoter activity. Collectively, these findings indicate that activation of Wnt signaling up-regulates VEGF expression in colonic neoplasia.
