The alterations induced in dendritic cells (DCs) in the cancer microenvironment have not been extensively explored. We found that the tumor-associated factor TGF-β may selectively upregulate the expression of miR-27a via the SP1 transcription factor. Importantly, miR-27a altered the activity of NF-κB and MAPKs (mitogen-activated protein kinases) p38, JNK (c-Jun N-terminal kinases) and ERK (extracellular signal-regulated kinase 1/2). It influences the production of proinflammatory cytokines by targeting TAB3, p38 MAPK, MAP2K4 and MAP2K7. As a consequence, miR-27a hampered the DC-mediated differentiation of Th1 and Th17 cells in vitro and in vivo, but it promoted the DC-mediated accumulation of Tr1 (CD4(+)IL-10(+)) and Treg (CD4(+)CD25(+)Foxp3(+)) cells in vivo. The repeated infusion of miR-27a-engineered DCs into tumor tissues accelerated tumor growth, indicating that miR-27a is a potential target for tumor immunotherapy.Genes and Immunity advance online publication, 4 October 2012; doi:10.1038/gene.2012.45.
