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: We have previously reported that stressed apoptotic tumor cells are more immunogenic in vivo than nonstressed ones . Using confocal microscopy we have confirmed our previous observation that heat-stressed apoptotic 12B1-D1 leukemia cells ( BCR-ABL(+) ) express HSP60 and HSP72 on their surface . To explore how the immune system distinguishes stressed from nonstressed apoptotic tumor cells , we analyzed the responses of dendritic cells to these 2 types of apoptotic cells . We found that nonstressed and heat-stressed apoptotic 12B1-D1 cells were taken up by dendritic cells in a comparable fashion . However , when stressed apoptotic 12B1-D1 cells were coincubated with immature dendritic cells for 24 hours , this resulted in greater up-regulation of costimulatory molecules ( CD40 , CD80 , and CD86 ) on the surface of dendritic cells . Moreover , stressed apoptotic 12B1-D1 cells were more effective in stimulating dendritic cells to secrete interleukin-12 ( IL-12 ) and in enhancing their immunostimulatory functions in mixed leukocyte reactions . Furthermore , we demonstrated that immunization of mice with stressed apoptotic 12B1-D1 cells induced the secretion of T helper-1 ( T(H)1 ) profile of cytokines by spleen cells . Splenocytes from mice immunized with stressed apoptotic cells , but not nonstressed ones , were capable of lysing 12B1-D1 and the parental 12B1 line , but not a B-cell leukemia line , A20 . Our data indicate that stressed apoptotic tumor cells are capable of providing the necessary danger signals , likely through increased surface expression of heat shock proteins ( HSPs ) , resulting in activation/maturation of dendritic cells and , ultimately , the generation of potent antitumor T-cell responses .
