NOS2 and Parkinson disease: Compared with the PD and NC groups, there was a significant decrease in iNOS positive cells in the miR-96 mimic group (P < 0.05), while iNOS positive cells in the miR-96 inhibitor and CACNG5 groups were notably decreased (P < 0.05); there was no obvious difference observed in the miR-96 mimic + CACNG5 group (P > 0.05) (Fig. 5a and b).
