The molecular mechanisms underlying the dysregulation of microRNAs (miRs) have been previously documented in breast cancer. miR-198 has been reported to be deregulated in several human cancers. However, the detailed effects of miR-198 on breast cancer progression remain unclear. Using quantitative polymerase chain reaction analysis, we demonstrated in the present study that miR-198 was downregulated in breast cancer tissues and cell lines, and that downregulation of miR-198 was significantly correlated with lymph node metastasis. Functional studies revealed that miR-198 inhibited cell proliferation and migration and promoted cell adhesion in aggressive breast cancer cells in vitro. In addition, we observed that CUB domain-containing protcin 1 ( CDCP1) was a direct target of miR-198, and that knockdown of CDCP1 inhibited cell proliferation and migration, and promoted cell adhesion, which was similar to the effects of overexpression of miR-198. Taken together, we provide evidence to characterize the role of miR-198/CDCP1 interaction in breast cancer, which may be useful in breast cancer therapy.
