LRRK2 and Parkinson disease: By using the Targetscan tool (http://www.targetscan.org), they found several gene targets of the 3 miRNAs to be closely related to the pathological process of PD, including Parkin RBR E3 ubiquitin protein ligase (miR-19b), LRRK2/PARK8 (miR-19b), and ATP13A2/PARK9 (miR-24 and miR-195) [69].
