Geng et al. observed that the overexpression of miR-124-3p exerted a neuroprotective action in PD by alleviating neuronal injury via dramatically suppressing the activity of STAT3 through directly targeting the 3’UTR of STAT3 mRNA, attenuating MPP iodide-induced apoptosis, neuroinflammation, and oxidative stress [49]. Here, STAT3 is linked to Parkinson disease.
