SNCA and Parkinson disease: For instance, it has been shown that miRNAs (e.g., miR-153 and miR-7) could regulate α-synuclein accumulation that affects the formation of Lewy bodies, the typical characteristic of PD (7); miR-34b and miR-34c could control DJ-1 and Parkin, respectively (8); and lncRNA NaPINK1 can stabilize the expression of PD-susceptibility gene PINK1 in neurons (9).
