Outline of Final Research Achievements |
In this study, the effect of high fat diet (HFD)-induced obesity and/or diabetes mellitus on liver cancer and tumor-associated macrophages (TAMs) was examined. Model mice for liver cancer were generated by intraperitoneally injecting dimethylnitrosamine (DEN), a chemical carcinogen. HFD treatment increased the number and the size of DEN-induced liver cancers, as well as the number of macrophages inside or outside of the cancers. In macrophage-specific HIF-1a knockout mice (KO), the expression levels of both M1 and M2 activation markers were decreased in macrophages separated from the liver. Interestingly, the number of liver cancers was decreased in the KO mice, although their size was not affected, comparedwithe the wild type mice. These results suggest that TAMs, which were activated in HIF-1a-dependent manor, may promote carcinogenesis in the liver of HFD-fed mice.
