1 Anticancer drug bortezomib increases interleukin-8 expression in human monocytes. Bortezomib C-X-C motif chemokine ligand 8 Homo sapiens
2 Since monocytes and macrophages are major producers of IL-8, the goal of this study was to test the hypothesis that BZ increases the IL-8 expression in human monocytes and macrophages. Bortezomib C-X-C motif chemokine ligand 8 Homo sapiens
3 Since monocytes and macrophages are major producers of IL-8, the goal of this study was to test the hypothesis that BZ increases the IL-8 expression in human monocytes and macrophages. Bortezomib C-X-C motif chemokine ligand 8 Homo sapiens
4 Here, we show that BZ dramatically increases the IL-8 expression in lipopolysaccharide (LPS)-stimulated U937 macrophages as well as in unstimulated U937 monocytes and peripheral blood mononuclear cells, while it inhibits expression of IL-6, IL-1 and tumor necrosis factor-alpha. Bortezomib C-X-C motif chemokine ligand 8 Homo sapiens
5 In addition, our results show that the underlying mechanisms involve p38 mitogen-activated protein kinase, which is required for the BZ-induced IL-8 expression. Bortezomib C-X-C motif chemokine ligand 8 Homo sapiens
6 Together, these data suggest that the BZ-increased IL-8 expression in monocytes and macrophages may represent one of the mechanisms responsible for the BZ resistance and indicate that targeting the p38-mediated IL-8 expression could enhance the BZ effectiveness in cancer treatment. Bortezomib C-X-C motif chemokine ligand 8 Homo sapiens
7 Together, these data suggest that the BZ-increased IL-8 expression in monocytes and macrophages may represent one of the mechanisms responsible for the BZ resistance and indicate that targeting the p38-mediated IL-8 expression could enhance the BZ effectiveness in cancer treatment. Bortezomib C-X-C motif chemokine ligand 8 Homo sapiens
8 Together, these data suggest that the BZ-increased IL-8 expression in monocytes and macrophages may represent one of the mechanisms responsible for the BZ resistance and indicate that targeting the p38-mediated IL-8 expression could enhance the BZ effectiveness in cancer treatment.
