The notable findings in PD datasets are briefly presented as follows: (a) increased expression levels in PD SN (Fig. 3a, within GSE26927: ATG3, LAMP2 and RUBCN; within GSE7621 and GSE43490: LAMP2 and RUBCN), (b) decreased expression levels in PD SN (Fig. 3a, within GSE26927: MAP1LC3 and PINK1; also note decreased expression of PINK1 within the dataset GSE7621) and (c) increased expression levels in PD LC (Fig. 3a, in GSE43490: LAMP2). Here, PINK1 is linked to Parkinson disease.
