PARK7 and Parkinson disease: Candidate targets of miR-29s include: oxidative stress sensor PARK7 (DJ-1), Parkin substrate GPR37, targets related to apoptotic processes Puma, Bim, Bak, Bcl2, IGF1 and AKT1, microglial phagocytosis-related CDC42, and the epigenetic molecules DNMT3A, DNMT3B and HDAC4. miR-29a, and miR-29c were recently found to be downregulated in the same patients with idiopathic rapid eye movement behavior disorder after they were diagnosed with PD and dementia with Lewy bodies35.
