MicroRNA-874 (miR-874), a novel cancer-associated microRNA (miRNA), has been
reported to play a suppressive role in multiple malignancies. However, its
function in cell migration and invasion in hepatocellular carcinoma (HCC) and the
mechanisms responsible remain unclear. Here, we found miR-874 to be significantly
downregulated in HCC tissues and cell lines. Moreover, this decreased expression
strongly correlated with clinical stage and lymph node metastasis. Accordingly,
ectopic expression of miR-874 in HCC cells markedly inhibited their migration,
invasion, and epithelial-mesenchymal transition (EMT). Concerning the underlying
mechanism, SRY (sex-determining region Y) -box 12 (SOX12) was identified as a
direct target of miR-874, and its expression was found to be inversely correlated
with that of this miRNA in HCC cells. Importantly, SOX12 knockdown had an
inhibitory effect on HCC cells similar to that caused by miR-874 overexpression,
whereas SOX12 overexpression in these cells negated the suppressive effects of
miR-874 on migration, invasion, and EMT. Overall, these findings demonstrate that
miR-874 inhibits metastasis and EMT in HCC by targeting SOX12, suggesting that
this miRNA may constitute a promising therapeutic target for this disease.
