Exploring temporal and sex-linked dysregulation in Alzheimer disease phosphoproteome.

ABSTRACT: This study aims to characterize dysregulation of phosphorylation for the 5XFAD mouse model of Alzheimer disease (AD). Employing global phosphoproteome measurements, we analyze temporal (3, 6, and 9 months) and sex-dependent effects on mouse hippocampus tissue to unveil molecular signatures associated with AD initiation and progression. Our findings reveal consistent phosphorylation of known AD biomarkers APOE and GFAP in 5XFAD mice, alongside candidates BIG3, CLCN6, and STX7, suggesting their potential as biomarkers for AD pathology. In addition, we identify PDK1 as a significantly dysregulated kinase at 9 months in females, and the regulation of gap junction activity as a key pathway associated with Alzheimer disease across all time points.
