MIR186 is a microRNA that has been identified as down-regulated in human prostate cancer (PCa) specimens, particularly in metastatic patients [PMC8431208]. Recent research has suggested that MIR186 acts as a metastasis suppressor in PCa [PMC8431208]. Furthermore, MIR186 has been found to play a tumor suppressive role in PCa by inhibiting tumorigenesis and metastasis, with its expression level being inversely correlated with clinical grade and pathological grading [PMC5078081]. Additionally, low expression of MIR186 has been associated with poor patient survival [PMC5078081]. Correlation analyses have revealed a positive correlation between miR25 and IL-12, while no significant correlations were found between miR21 and IL-21 or MIR186 and IL-12 [PMC9013931]. The role of the long non-coding RNA (lncRNA) PVT1 in regulating the expression of MIR186 has been demonstrated using lncRNA PVT1 silenced cholangiocarcinoma (CCA) cell lines [PMC8286192]. Overall, these findings highlight the importance of MIR186 as a potential therapeutic target for PCa due to its involvement in metastasis suppression and tumor suppression.

Annotation confidence High
Do you think this miRNA is real?
This miRNA sequence is predicted based on homology to a verified miRNA from mouse. Expression of this miRNA was also verified in a human osteoblast sarcoma cell line [1]. The mature sequence shown here represents the most commonly cloned form from large-scale cloning studies [2].
