Apc(+/Min) mice when crossed with Ink4a/arf-/-mice, exhibited increased angiogenesis of colorectal tumors suggesting that dysregulation of Cdk4 (due to loss of Ink4a-mediated suppression) may contribute to enhanced angiogenesis. To demonstrate a direct role for Cdk4 in angiogenesis, we crossed mice that have an activated Cdk4, Cdk4(R24C/R24C) mice, with Apc(+/Min) mice and examined levels of angiogenesis in intestinal tumors formed. Our results show an increase in the percentage of highly vascularized tumors in Cdk4(R24C/R24C):Apc(Min/+) and Cdk4(+/R24C):Apc(Min/+) mice compared to Cdk4(+/+):Apc(Min/+) mice. In addition immunohistochemical analysis showed an increase in CD-31 staining localized to endothelial cells of Cdk4(R24C/R24C):Apc(Min/+) mouse tumors, supporting the hypothesis of increased vasculature in these tumors. Further analysis showed an increase in the expression of the E2F1 target proteins Vegf-b and Cyclin A in Cdk4(R24C/R24C):Apc(+/Min) intestinal tumors. Together these data suggest that the dysregulated Cdk4 gene plays an important role in angiogenesis during intestinal tumor formation and may in part act via increasing E2F1 target proteins. This is the first report to show that Cdk4 has a direct role in angiogenesis in vivo and may be an important drug target to reduce or prevent angiogenesis during intestinal tumor formation."xsd:string |
