Abstract
Abstract Squamous cell cancers are the most common type of epithelially derived human cancers and arise from a number of diverse sites. They share a number of common genetic alterations and environmental exposures. Employing oral and esophageal cancers as prototypes, we have developed three-dimensional (3D) or organoptypic models that represent a form of human tissue engineering (Genes and Development 2007; Journal of Clinical Investigation 2008). These approaches underscore the combinatorial roles of EGFR signaling and p53 mutation in fostering tumor cell migration and invasion in the microenvironment. Microarray analyses reveal specific effectors in the adhesion family of genes that might be exploited as biomarkers for detection and targets for new therapeutics. We have also generated genetically engineered mouse models that reveal the effects of cyclin D1 overexpression in concert with p53 loss, as well as the role of p120-catenin loss in the initiation and progression of cancer.
