Melanoma differentiation associated gene 7/Interleukin-24 (MDA-7/IL-24) is a secreted cytokine which acts as a tumor suppressor. It is capable of selectively killing cancer cells, regardless of anatomic origin, while sparing normal cells. miRNAs are master regulators of gene expression that can play two roles in cancer: tumor-suppression and oncogenesis. We identified a number of miRNAs that are regulated by MDA-7/IL-24 using a PCR plate array containing probes for miRNAs known to play a role in prostate cancer. We independently validated the array with qRT-PCR to identify three miRNAs which are downregulated by MDA-7/IL-24 treatment in DU145, PC3, and PC3ML prostate …
