GFAP was significantly up-regulated in AD (Fig. 2E), although a non-significant tendency to up-regulation was also observed in both PD groups (PD M vs. C M: FC: 1.28; P-val: 0.14; PD F vs. C F: FC 1.57; P-val: 0.07) (Additional file 3: Table S3). This evidence concerns the gene GFAP and Parkinson disease.
