MicroRNA (miR)-124: A Promising Therapeutic Gateway for Oncology

SIMPLE SUMMARY: MicroRNA-124 (miR-124) is a small non-coding RNA that regulates gene expression and is abundantly expressed in the brain and immune system. Dysregulated expression of miR-124 is associated with several cancer types, making it a potential therapeutic target in oncology. We demonstrate the potential of miR-124 as a target in various cancer types. ABSTRACT: MicroRNA (miR) are a class of small non-coding RNA that are involved in post-transcriptional gene regulation. Altered expression of miR has been associated with several pathological conditions. MicroRNA-124 (miR-124) is an abundantly expressed miR in the brain as well as the thymus, lymph nodes, bone marrow, and peripheral blood mono-nuclear cells. It plays a key role in the regulation of the host immune system. Emerging studies show that dysregulated expression of miR-124 is a hallmark in several cancer types and it has been attributed to the progression of these malignancies. In this review, we present a comprehensive summary of the role of miR-124 as a promising therapeutic gateway in oncology.
