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: OBJECTIVE As we previously demonstrated , the inhibitory effect of iodine on thyroid cell growth is mediated by iodolactones , especially 6-iodo-5-hydroxy-eicosatrienoic acid ( delta-iodolactone ) . In this communication we compare the effect of iodide , molecular iodine and delta-iodolactone on growth inhibition and apoptosis on three human thyroid carcinoma cell lines ( B-CPAP cells , FTC-133 cells and 8505C cells ) as well as on human breast cancer cells ( MCF 7 ) . METHODS Thyroid carcinoma cells were cultured in Dulbecco's modified Eagle's medium ( DMEM ) and MCF 7 cells in Rowswell Park Memorial Institute ( RPMI ) culture medium , both containing 10% ( v/v ) Fetal Calf Serum ( FCS ) , until they were confluent . Around 2000 cells were then distributed in 12-well plates and grown for 48 h in either DMEM ( thyroid cancer cells ) or in RPMI medium ( MCF 7 cells ) both containing 5% FCS . Thereafter , different concentrations of iodide , iodine or delta-iodolactone were added for 24 h . Growth rate was estimated by cell counting in a Coulter Counter adapted for epithelial cells . Apoptosis was determined by a mitochondrial potential assay . RESULTS The growth rate of B-CPAP cells was unaffected by iodide , but was reduced by high concentreations of molecular iodine ( 100 and 500 microM ) . However , delta-iodolactone significantly reduced cell proliferation already with low concentrations ( 5 microM and 10 microM ) and further in a dose-dependent manner up to 82% . FTC-133 and 8505C cells were unaffected by iodide , iodine or delta-iodolactone . In contrast , in MCF 7 cells , molecular iodine ( 100 microM ) inhibited growth from 100% to 83% but delta-iodolactone ( 1 , 5 and 10 microM ) dose-dependently decreased growth rate from 100% to 82% and 62% , respectively . The inhibition of growth was through apoptosis , and not necrosis , as the amount of apoptotic cells corresponded to the growth inhibition . CONCLUSION delta-Iotaodolactone seems to be the main iodocompound which can inhibit growth and induce apoptosis in B-CPAP cells as well as in MCF 7 breast cancer cells .
