Additionally, miRNA-34a, miRNA 122, and miRNA 132 inhibit Sirt1; regulation of miRNA-34a and miR132 was reported for AD, while miRNA132 was reported for PD in the literature [73,74,75], which potentially corroborates the involvement of SIRT1 in both AD and PD. This evidence concerns the gene SIRT1 and Parkinson disease.
