Comparison of individuals without the need of dementia (NL = CDR 0), with questionable-mild (CDR 0.5-1) and with moderate to extreme dementia (CDR 2-5) showed higher Barnidipine Epigenetic Reader Domain levels of MDM4, ATM and ATR gene expression in individuals with dementia (F2, 112 = four.037, p = 0.02 (MDM4); F2,112 = four.357, p = 0.015 (ATM) and F2,112 = three.038, p = 0.052 (ATR); see Figure 2). Comparisons of men and women with and with out AD-associated neuropathology also showed higher levels of MDM4 and ATM gene expression as a function of rising neuritic plaque (NP) density (F3,112 = 3.601, p = 0.016 and F3,112 = four.802, p = 0.009, Catalase web respectively) and Braak neuropathological stages (F4,112 = three.042, p = 0.020 and F4,112 = two.816, p = 0.029, respectively). Changes in ATR gene expression as a function of NP density or Braak neuropathological stages weren’t important, but showed nominal increases. These final results suggest that expression of MDM4, ATM and ATR genes is dysregulated in the earliest recognizable stages of AD-dementia. Levels of MDM4 and ATM had been also upregulated early through progression of AD-associated neuropathology and remain elevated throughout the course of AD. Partial correlations of MDM4 and ATM gene expression controlling for Age, pH and PMI demonstrated substantial associations with CDR (r = 0.
