## Abstract Immortalized and cancer cells maintain their telomeres by activation of a telomere maintenance mechanism (TMM). In ∼85% of cancers telomerase is activated (TA) but in some tumours, in particular sarcomas, an alternative lengthening of telomeres (ALT) pathway is used. Liposarcomas are th

## Abstract Unlimited proliferative potential is a hallmark of cancer, and can be achieved through the activation of telomere maintenance mechanisms (TMMs). Most tumors activate telomerase, but a significant minority, mainly of mesenchymal origin, uses a recombination‐based, alternative lengthening
## Abstract Two types of telomere maintenance mechanisms (TMMs) have been described in human tumors: telomerase activation and alternative lengthening of telomeres (ALT). Although the vast majority of epithelial tumors rely on telomerase activation, many mesenchymal tumors rely on ALT for telomere
