MicroRNA-143 inhibits proliferation and migration of prostate cancer cells.

Background: Prostate cancer (PC) is one of the most prevalent types of malignancies in males. Here, we replaced the miRNA-143 in PC cells by using a vector-based miRNA-143 transfection approach.Materials and methods: The miRNA-143 vector was transfected into the cells and qRT-PCR was applied to assess the expression of target genes in PC3 cells. Also, the MTT, scratch wound-healing, and DAPI staining assays were done to assess the proliferation, migration, and apoptosis of the cells, respectively.Results: The findings of the qRT-PCR determined the enhanced expression of miRNA-143 and other cancer-associated genes. The MTT and wound-healing assays revealed the proliferation and migration reduction in the transfected cells in comparison to control cells that contain an empty vector.Conclusion: The miRNA-143 has a significant impact on cell growth and migration during PC metastasis, and it may be a promising candidate for molecular therapies of PC.
