PINK1 and Parkinson disease: miR-21 and miR-106b were shown to be involved in the regulation of phosphatase and tensin homolog (PTEN), a protein implicated in the development of Parkinson’s disease (PD) through activation of two genes involved in neural protection from oxidative stress, PTEN-induced putative kinase (PINK1), and parkinson disease 7 (PARK7, also known as DJ-1) [80].
