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: 22Rv1 is a common prostate cancer cell line used in xenograft mouse experiments as well as in vitro cell culture assays to study aspects of prostate cancer tumorigenesis . Recently , this cell line was shown to harbor multiple copies of a gammaretrovirus , called XMRV , integrated in its genome . While the original prostate cancer xenograft CWR22 is free of any retrovirus , subsequently generated cell lines 22Rv1 and CWR-R1 , carry this virus and additionally shed infectious gammaretroviral particles in their supernatant . Although XMRV most likely was generated by recombination events in cell culture this virus has been demonstrated to infect human cells in vitro and 22Rv1 as well as CWR-R1 cells are now considered biosafety 2 reagents . Here , we demonstrate that 22Rv1 cells with reduced retroviral transcription show reduced tumor angiogenesis and increased necrosis of the primary tumor derived from xenografted cells in scid mice when compared to the parental cell line . The presence of XMRV transcripts significantly increases secretion of osteopontin ( OPN ) , CXCL14 , IL13 and TIMP2 in 22Rv1 cells . Furthermore , these data are supported by in vitro cell invasion and differentiation assays . Collectively , our data suggest that the presence of XMRV transcripts at least partially contributes to 22Rv1 characteristics observed in vitro and in vivo with regard to migration , invasion and tumor angiogenesis . We propose that data received with 22Rv1 cells or equivalent cells carrying xenotropic gammaretroviruses should be carefully controlled including other prostate cancer cell lines tested for viral sequences .
