Sun et al. reported that miR-212-5p could attenuate damage and loss of dopaminergic neuron in the mouse model of Parkinson’s disease [67]; Smith and the colleagues reported that miR-132/212 knockout mice have impaired memory while treatment with miR-132 rescues the memory deficits by reducing the phosphorylated tau [24]. This evidence concerns the gene MAPT and Parkinson disease.
