Abstract excerpt
Elimination of both alleles of the gene that encodes the cyclin kinase inhibitor p21(WAF1/cip1) increases the frequency and size of intestinal tumors in Apc1638+/- mice that inherit a mutant allele of the Apc gene, and intermediate effects are seen if a single p21 allele is inactivated. The increased tumor formation is associated with altered cell maturation in the intestinal mucosa of the p21-deficient...
