LncRNA H19 diminishes dopaminergic neuron loss by mediating microRNA-301b-3p in Parkinson's disease via the HPRT1-mediated Wnt/β-catenin signaling pathway.
Jiang J, Piao X, Hu S, Gao J, Bao M
Overexpressing the long non-coding RNA H19 protects dopaminergic neurons in a mouse model of Parkinson's disease by activating the Wnt/beta-catenin signaling pathway. This protective effect occurs because H19 binds to microRNA-301b-3p, which prevents the suppression of HPRT1 and allows for increased expression of key neuronal genes like Nurr-1.
- H19 overexpression reduces dopaminergic neuron loss in Parkinson's disease mouse models.
- The mechanism involves H19 binding to miR-301b-3p to regulate HPRT1 levels.
- HPRT1 activation triggers the Wnt/beta-catenin pathway to support neuronal survival.
