Telomerase activity is associated with an increase in DNA methylation at the proximal subtelomere and a reduction in telomeric transcription
7 Jan 2009
Abstract excerpt
Tumours and immortalized cells avoid telomere attrition by using either the ribonucleoprotein enzyme telomerase or a recombination-based alternative lengthening of telomeres (ALT) mechanism. Available evidence from mice suggests that the epigenetic state of the telomere may influence the mechanism of telomere maintenance, but this has not been directly tested in human cancer. Here we investigated cytosine...
