microRNAs (miRNAs) regulate diverse cellular functions and signaling pathways via inhibiting the expression of their target genes. Given that miR‐128 mediates mitogen‐activated protein kinase signaling and production of reactive oxygen species and pro‐inflammatory chemokines in various types of cells and tissues, and that miR‐128 is differentially expressed in aged and diseased kidneys, we hypothesized that miR‐128 may play key roles in kidney inflammation. Hence, in this study, we evaluated the biological effects of miR‐128 in normal rat kidney (NRK) cells in vitro . Our results revealed that overexpression of miR‐128 enhanced expression of genes associated with inflammation, pro‐inflammatory cytokines and fibrosis in NRK cells. The recent reports showing that expression of miR‐128 is increased in liver and lung fibrosis, together with the findings in this study, suggest that miR‐128 may be a pro‐fibrotic miRNA that regulates fibrosis in various tissues.
