In contrast, in the rat GB cell line C6, miR-210-3p acts as a tumor suppressor as it inhibits both cell proliferation and migration by negatively regulating the iron–sulfur cluster assembly enzyme (Iscu) gene [89], which makes the miR-210-3p/Iscu axis a potential target for the treatment of this type of glioma. Here, ISCU is linked to central nervous system cancer.
