Extensive Telomere Erosion in the Initiation of Colorectal Adenomas and Its Association With Chromosomal Instability

Abstract

Telomere length distributions observed in colorectal polyps reflect the telomere length composition of the normal originating cells from which clonal growth was initiated. Originating cells containing both short telomeres and APC mutations may give rise to polyps that exhibit short telomeres and are prone to telomere dysfunction, driving genomic instability and progression to malignancy.
