We evaluated the effect of expressing the cell cycle regulator cdk2ap1 in epithelial or stromal cell compartments to reduce SCC growth in vitro and in vivo. Cell autonomous and/or non-cell autonomous expression of cdk2ap1 reduced tumor growth and invasion and altered cell cycle, adhesion, invasion, angiogenesis, and apoptotic gene expression, as assessed by several in vitro phenotype assays, quantitative real time PCR, and in vivo molecular imaging using a novel three-way xenograft animal model. Our findings suggest that the interactions between cancer cells and fibroblasts that promote abnormal growth can be minimized by expressing cdk2ap1, supporting a novel concept by which tumor/growth suppressor genes can impact tumorigenesis phenotypes from non-cell autonomous interactions within the tumor microenvironment.
