Research Abstract

micro RNAs (miRNAs) regulate many genes and therefore their expression abnormality cause various diseases including cancer. Previously, we identified some miRNAs that might be related with prostate cancer progression. In this study, we found that miR-30d expression in cancer cells and tissues is higher than in normal prostate cells and tissues. Further, miR-30d expression was associated with recurrence free survival ratio. Therefore miR-30d might be a prognosis factor for prostate cancer recurrence. We identified that SOCS1 was one of the targets for miR-30d. SOCS1 regulation by miR-30 was related with prostate cancer progression.
