Oligodendrocyte lineage gene 1 (Olig1) plays a key role in hypoxic-ischemic brain damage and myelin repair. miRNA-9 is involved in the occurrence of many related neurological disorders. Bioinformatics analysis demonstrated that miRNA-9 complementarily, but incompletely, bound oligodendrocyte lineage gene 1, but whether miRNA-9 regulates oligodendrocyte lineage gene 1 remains poorly understood. Dr. Lijun Yang and co-workers from Beijing Friendship Hospital, Capital Medical University in China prepared whole brain slices from a rat model of oxygen-glucose deprivation and explored dynamic expression pattern of Olig1 during hypoxic-ischemic brain damage and after miRNA-9 transfection. Results from their study showed that miRNA-9 possibly negatively regulated oligodendrocyte lineage gene 1 in brain tissues during hypoxic-ischemic brain damage. The relevant study has been reported in the Neural Regeneration Research.
