| Outline of Final Research Achievements |
This study has been carried out with the aim of elucidating the mechanisms how tumor microenvironments are developed during tumor progression. We have revealed that a subpopulation of glioma cells induces macrophages expressing iron-recycling genes under the iron-deficient stress, which suggests that stress response by tumor cells plays important roles in the development of tumor microenvironments. We also found that the induction of macrophages is potentially mediated by the epigenetic upregulation of CCL2 and GMCSF genes in tumor cells. Our findings could help establish new strategies for cancer therapy targeting microenvironments.
