OBJECTIVE: Long non-coding RNA DUXAP10 plays a significant role in the tumorigenesis and development of human cancer. The present study was performed to investigate the role of DUXAP10 in biological functions and underlying molecular mechanisms of prostate cancer cells.
MATERIALS AND METHODS: First, the quantitative reverse transcription-polymerase chain reaction (qRT-PCR) was used to detect the expression of DUXAP10 in human prostate cancer cell lines 22RV1, PC3, and DU145. Subsequently, small interfering RNAs (siRNAs) targeting at DUXAP10 mRNA were used to downregulate DUXAP10 expression. Then, the biological functions of DUXAP10 in prostate cancer cells, proliferation, migration, and apoptosis were studied by the 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT) assay, colony-formation assay, cell cycle analysis, transwell migration assay, wound healing assay, and cell apoptosis assay, respectively. Finally, qRT-PCR analysis and Western blot assay were used to investigate the molecular mechanisms of DUXAP10 underlying the progression of prostate cancer.
RESULTS: Results showed that the expression of DUXAP10 was higher in PC3 and DU145 cell lines than that in the 22RV1 cell line. Additionally, the knockdown of DUXAP10 could remarkably inhibit the proliferation, migration, and induce apoptosis of prostate cancer cells, and significantly increase the number of G0/G1 cells in PC3 and DU145 cell lines. Moreover, DUXAP10 could promote the development of prostate cancer by regulating the process of epithelial-mesenchymal transition (EMT).
CONCLUSIONS: The findings of this study suggested that the down-regulation of DUXAP10 expression suppressed the progression of prostate cancer by inhibiting cell proliferation, migration and promote cell apoptosis.
