Multi‐tissue profiling of RNA and DNA‐methylation signatures of progressive tau neuropathology in tau transgenic mice

Intracellular abnormal aggregation of hyperphosphorylated tau protein is a neuropathological hallmark associated with Alzheimer’s Disease (AD). The insoluble tau aggregates called neurofibrillary tangles lead to microtubule dysfunction and neurodegeneration with AD progression. The TG4510 transgenic mice overexpressing the P301L mutant human tau protein exhibit region‐specific tau inclusions, brain atrophy, and behavioral deficits, thereby serving as a widely used animal model of tauopathy in AD. This study aims to characterize the tissue‐specific transcriptomic and epigenomic signatures of progressive tau pathology in TG4510 mice as well as investigate the correlation of brain and blood expression and epigenomic changes.
