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: BACKGROUND The most deadly form of cancer is not lung or colon , breast or prostate ; it is any cancer that has become metastatic . Mortality due to metastatic melanoma , one of the most aggressive and deadly cancers , has increased steadily over the last several decades . Unfortunately , the arsenal of chemotherapeutic agents available today is most often unsuccessful at extending and improving the life expectancy of afflicted individuals . We sought to identify an effective and nontoxic agent against metastatic melanoma . METHODOLOGY/PRINCIPAL FINDINGS We chose to study Cloudman S-91 mouse melanoma cells ( sub-clone M3 , CCL53.1 ) because these cells are highly aggressive and metastatic , representing one of the deadliest types of cancer . Melanoma cells also had an experimental advantage because their morphology , which is easily monitored , relates to the physiology of metastatic cells and normal melanocytes . We chose to test methyl sulfone as a chemotherapeutic agent for two reasons . Because of its chemical structure , we speculated a potential anti-cancer activity by targeting microtubules . Equally important , methyl sulfone has a well-established safety profile in humans . Surprisingly , we found that malignant melanoma cells exposed to methyl sulfone demonstrated the loss of phenotypes characteristic of malignant cells , and the reemergence of phenotypes characteristic of healthy melanocytes . Briefly , over time methyl sulfone induced contact inhibition , loss of ability to migrate through an extracellular matrix , loss of anchorage-independent growth , proper wound healing followed by contact inhibition , irreversible senescence followed by arborization with melanosomes in arbors as seen in normal melanocytes . CONCLUSIONS/SIGNIFICANCE Methyl sulfone may have clinical potential as a non-toxic agent effective against metastatic melanoma . Additionally , methyl sulfone has promise as a tool to explore molecular mechanisms of metastatic transformation as well as fundamental processes such as cell migration , contact inhibition , wound healing and cellular senescence .
