| 値 | Copper is one of the essential micronutrients, and copper-containing enzymes contribute to crucial functions in the body. Lysyl oxidase is a copper-containing enzyme that remodels the extracellular matrix by cross-linking collagen and elastin. The overexpression of lysyl oxidase was recently shown to promote tumor metastasis. M2-like macrophages were also found to significantly accumulate in the tumor microenvironment, and correlated with a poor patient’s outcome. We speculate that M2-like macrophages promote tumor progression via lysyl oxidase expression. Epigenetics, a mitotically heritable change in gene expression without any change in DNA sequencing, is also associated with tumor progression. However, the relationship between lysyl oxidase expression in M2-like macrophages and epigenetics remains unclear. Lysyl oxidase expression was significantly induced in human leukemic THP-1 cell-derived M2-like macrophages. Furthermore, the level of histone H3 tri-methylation at lysine 27 was decreased, and a pre-treatment with a H3K27 demethylase inhibitor notably suppressed lysyl oxidase expression in M2-like macrophages. Lysyl oxidase derived from M2-like macrophages also enhanced breast cancer cell migration, and this was suppressed by a H3K27 demethylase inhibitor. The present results suggest the mechanism of lysyl oxidase expression in M2-like macrophages as an aspect of epigenetics, particularly histone methylation. | |||||
