LRRK2 and Parkinson disease: These gene targets, which include ATP13A2/PARK9 (targeted by miR-24 and miR-195), LRRK2/PARK8 (targeted by miR-19b), and Parkin RBR E3 ubiquitin protein ligase (PARK2; targeted by miR-19b), are strongly correlated with various neurodegenerative processes, neuronal apoptosis, and regeneration that underlie PD [92].
