TFRC and Parkinson disease: In contrast, TFRC protein level was found to be significantly associated with PMI in AD (TFRC in AD vs. PMI: Slope: -1.074, p-value = 0.0174, R-squared = 0.07609; Supplementary Figure S3E) but not in the CN (TFRC in CN vs. PMI: Slope: 0.3298, p-value = 0.7782, R-squared = 0.005451; Supplementary Figure S3D) and PD (TFRC in PD vs. PMI: Slope: -0.9503, p-value = 0.3753, R-squared = 0.03156; Supplementary Figure S3F) patient groups.
