| MicroRNAs are characterized as small, single-stranded, non-coding RNA molecules that bind to their target
mRNA to prevent protein synthesis. MicroRNAs regulate various normal processes; however, they are aberrantly
regulated in many cancers. They control the expression of various genes, including cancer-related genes. This
causes microRNAs to be considered as a good target for further investigations for designing novel therapeutic
strategies.
Since miR124 is known for some time already, it has a tumor-suppressing role in various cancers. Numerous
studies indicate its definite roles in malignant processes such as epithelial-to-mesenchymal transition, cell cycle
arrest, metastasis, cancer stem cell formation and induction of apoptosis. However, some studies have indicated
a dual role for miR-124 in oncogenic processes like autophagy and multi-drug resistance. In this article, we will
review recent researches on the biological functions and clinical implications of miR-124. Subsequently, we will
discuss future perspectives in terms of the roles of this miRNA in cancers. |
