Bortezomib (BZ) is the first clinically approved proteasome inhibitor that has shown remarkable anticancer activity in patients with hematological malignancies. However, many patients relapse and develop resistance; yet, the molecular mechanisms of BZ resistance are not fully understood. We have recently shown that in solid tumors, BZ unexpectedly increases expression of the pro-inflammatory and pro-angiogenic chemokine interleukin-8 (IL-8), while it inhibits expression of other NFκB-regulated genes. 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. 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-α. 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. 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.
