Short Telomeres Initiate Telomere Recombination in Primary and Tumor Cells

Abstract excerpt

Human tumors that lack telomerase maintain telomeres by alternative lengthening mechanisms. Tumors can also form in telomerase-deficient mice; however, the genetic mechanism responsible for tumor growth without telomerase is unknown. In yeast, several different recombination pathways maintain telomeres in the absence of telomerase-some result in telomere maintenance with minimal effects on telomere length. To...
