http://purl.uniprot.org/citations/9060821http://www.w3.org/2000/01/rdf-schema#comment"Dysplastic colon adenomas are thought to arise from growth of clones of APC -/-colonic epithelial cells. Isolated clusters of dysplastic crypts are often observed in patients with familial adenomatous polyposis. These patients have genotype APC +/-, and the clusters of dysplastic crypts (called microadenoma or aberrant crypt foci) are thought to represent an early stage in the expansion of a mutant clone of APC -/-cells. It is thought that the growth of these clusters of mutant crypts results from crypt replication through a process similar to what occurs in the normal crypt cycle. We measured the relative replication rate of mutant crypts by analyzing the size of clusters of mutant crypts in APC +/-individuals and found that mutant APC -/-crypts replicate more rapidly than do normal APC +/-(i.e., nonneoplastic) crypts. In contrast, the replication rate of mutant crypts in Apc +/-mice is not significantly different from that of normal crypts, thus supporting previous findings that aberrant crypt foci do not contribute significantly to the colon adenoma population in adult Apc +/-mice. Intriguingly, we found an effect of Apc heterozygosity on the frequency of branching crypts in young mice."xsd:string
