The task is to decide the Hallmarks of Cancer (HOC) taxonomy of the article based on its abstract. The input is an abstract text. There are 10 topics you will need to decide whether the article is related to. Topics: sustaining proliferative signaling, evading growth suppressors, resisting cell death, enabling replicative immortality, inducing angiogenesis, activating invasion and metastasis, genomic instability and mutation, tumor promoting inflammation, cellular energetics, avoiding immune destruction. The output should be topics from the above 10 topics, that are related to the input article. Please note one article can be related to multiple topics. Output format: provide a semicolon-separated list of relevant topics.

    INPUT: Telomerase is a ribonucleoprotein enzyme that functions to maintain telomeres , the terminal DNA that protects chromosomal integrity , regulating cellular replicative life span . Telomerase is not expressed in most normal human somatic cells but is active in stabilizing telomeres of certain self-renewing cell populations and most malignant cells , making the enzyme an appealing target for anticancer therapy . We describe here a novel cross-species approach to telomerase inhibition . Ectopic expression of the human telomerase catalytic reverse transcriptase component in murine cells inhibited endogenous murine telomerase activity . Using this approach , telomerase inhibition in immortal murine fibroblasts resulted in critical telomere shortening , leading to slowed proliferation , abnormal morphology , altered cell cycle , and telomere dysfunction with cytogenetic instability , followed by apoptotic cell death . Subpopulations of two telomerase-inhibited clones escaped widespread apoptosis , showing proliferative recovery in culture despite persistently inhibited telomerase activity with progressive telomere shortening and dysfunction . This study , by targeting immortal murine cells for telomerase inhibition , demonstrates the importance of telomerase to murine cell immortalization and telomere maintenance . Moreover , the murine model used here should prove useful in further evaluating telomerase inhibition as an anticancer therapy .
    OUTPUT:
