As compared with the PD and NC groups, the miR-96 mimic group had increased mRNA and protein expression of iNOS (P < 0.05), the miR-96 inhibitor and CACNG5 groups had decreased mRNA and protein expression of iNOS (P < 0.05), while the mRNA and protein expression of iNOS had an insignificant alteration in the miR-96 mimic + CACNG5 group (P > 0.05) (Fig. 5d, e and f). This evidence concerns the gene NOS2 and Parkinson disease.
