Another miRNAs is miR-544 that was increased in the brain tissues of LOPD patients (Tatura et al., 2016) and can directly bind to 3′UTR of PARK7 mRNA region to suppress PARK7 expression (Jin et al., 2016), however, whether miR-544 is implicated in PD progression remains unknown. The gene discussed is PARK7; the disease is Parkinson disease.
