Thrombospondin-1 gene expression affects survival and tumor spectrum of p53-deficient mice.

Abstract excerpt

In vitro and in vivo data indicate that thrombospondin-1 (TSP1) inhibits tumor progression in several ways including direct effects on cellular growth and apoptosis in the stromal compartment. To evaluate the importance of TSP1 for the progression of naturally arising tumors in vivo, we have crossed TSP1-deficient mice with p53-deficient mice. In p53-null mice, the absence of TSP1 decreases survival from 160 +/-...
