DYRK1A and Parkinson disease: Finally, a recent report identified miR-204-5p as a marker overexpressed in the serum of patients with Parkinson’s disease and proposed from data analyses that overexpression of this miR positively regulates DYRK1A mRNA expression, leading to the death of dopaminergic cells via DYRK1A-mediated ER stress and apoptotic signaling cascade [33].
