| Outline of Final Research Achievements |
Macrophages, which differentiated into tumor-associated macrophages in tumor microenvironment, are known to play crucial roles in tumor angiogenesis. However, the specific molecules and markers of these “angiogenesis-supporting macrophages” have not been fully defined. N-myc downstream regulated gene 1 (NDRG1), a gene responsible for a hereditary motor and sensory neuropathy (Lon-Charcot-Marie disease), plays pleiotropic roles in cell proliferation, development, differentiation, and tumorigenesis. We have previously reported that NDRG1 expression levels in cancer cells were closely correlated with tumor angiogenesis. However, how NDRG1 could affect tumor angiogenesis remains unclear. In this study, we asked how NDRG1 could specifically modulate tumor angiogenesis through its differentiation control of macrophage lineage cells by using NDRG1 knock out mice.
