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: The vast majority of breast cancers are carcinomas that arise from mammary epithelial cells ( MECs ) . One of the key early events in tumorigenic transformation is the ability of cells to overcome replicative senescence . However , the precise genetic changes that are responsible for this event in MECs is largely unknown . Here , we report that Bmi-1 , originally identified as a c-Myc cooperating oncoprotein , can bypass senescence , extend the replicative life span , and immortalize MECs . Furthermore , Bmi-1 was overexpressed in immortal MECs and several breast cancer cell lines . Overexpression of Bmi-1 in MECs led to activation of human telomerase reverse transcriptase ( hTERT ) transcription and induction of telomerase activity . Telomerase induction by Bmi-1 was an early event in the extension of the replicative life span and immortalization . Bmi-1 was not overexpressed in hTERT-immortalized MECs , suggesting that Bmi-1 functions upstream of hTERT . Although , c-Myc has been reported to induce telomerase in MECs , Bmi-1 appeared to act independently of c-Myc binding sequences in the hTERT promoter . Deletion analysis of the Bmi-1 protein suggested that the RING finger , as well as a conserved helix-turn-helix-turn domain , were required for its ability to induce telomerase and immortalize MECs . These data suggest that Bmi-1 regulates telomerase expression in MECs and plays a role in the development of human breast cancer .
    OUTPUT:
