ER Stress in PD. UPR markers were determined in post-mortem human brain samples from SNpc, Hippocampus and Cortex of sporadic PD patients and controls. The levels of GRP78 and ATF4 were determined in: (A) SNpc; (B) Hippocampus and (C) Cortex brain tissue homogenates. (D). Densitometric analysis of the levels of GRP78 and ATF4. The blots were re-probed for α-tubulin to confirm equal protein loading Values are mean ± SEM (n = 5, **p < 0.01 and ***p < 0.001, versus SNpc control subjects; ##p < 0.01, versus hippocampus control subjects). Full length blots are presented in the Supplementary Information.
