Abstract Prostate cancer is one of the most common malignant cancers in men. Recent studies have shown that microRNA-21 (miR-21) is overexpressed in various types of cancers including prostate cancer. Studies on glioma, colon cancer cells, hepatocellular cancer cells and breast cancer cells have indicated that miR-21 is involved in tumor growth, invasion and metastasis. However, the roles of miR-21 in prostate cancer are poorly understood. In this study, the effects of miR-21 on prostate cancer cell proliferation, apoptosis, and invasion were examined. In addition, the targets of miR-21 were identified by a reported RISC-coimmunoprecipitation-based biochemical method. Inactivation of miR-21 by antisense oligonucleotides in androgen-independent prostate cancer cell lines DU145 and PC-3 resulted in sensitivity to apoptosis and inhibition of cell motility and invasion, whereas cell proliferation were not affected. We identified myristoylated alanine-rich protein kinase c substrate (MARCKS), which plays key roles in cell motility, as a new target in prostate cancer cells. Our data suggested that miR-21 could promote apoptosis resistance, motility, and invasion in prostate cancer cells and these effects of miR-21 may be partly due to its regulation of PDCD4, TPM1, and MARCKS. Gene therapy using miR-21 inhibition strategy may therefore be useful as a prostate cancer therapy.
