When the levodopa was injected in order to cause dyskinesia, the Areg knocked down group showed an inhibited Areg protein expression (p = 0.0058, t = 7.082, df = 3 Figure 8B,C) and consequently a significant decrease in total AIMs score is relative to the scramble injected group (Figure 8D,E). Here, AREG is linked to Dyskinesia.
