STAT3 and Parkinson disease: In neurodegenerative diseases, the investigation of why paraquat (PQ) increases the risk of Parkinson’s disease (PD) found that PQ induces the m6A modification of lncRNA CDC5L and lncRNA STAT3, affecting their expression, increasing intracellular ROS production, affecting autophagy-related biological functions, and, ultimately, causing damage to and the death of dopaminergic neurons, leading to the onset of PD [119,120].
