We measured MAPT promoter methylation in a brain tissue cohort of early-onset Alzheimer's disease (EOAD) with defined causative mutations in the PSEN1 gene (Normal = 10, PSEN1 AD = 10), and idiopathic late-onset Alzheimer's disease (Normal = 12, LOAD = 12).
Identification of the key molecules involved in chronic copper exposure-aggravated memory impairment in transgenic mice of Alzheimer's disease using proteomic analysis.
The Swedish mutation (K595N/M596L) of amyloid precursor protein (APP-swe) has been known to increase abnormal cleavage of cellular APP by Beta-secretase (BACE), which causes tau protein hyperphosphorylation and early-onset Alzheimer's disease (AD).
MAPT exons 1, 2 and 9-13 were sequenced in 59 patients with FTLD, and MAPT haplotypes were analysed in these patients, 122 patients with early onset Alzheimer's disease (eoAD) and 198 healthy controls.
With AT100, the amount of tau detected in FTDP-17 was 54% (P < 0.001) of that detected in EOAD, but no tau was detected in sporadic FTLD with Pick bodies using this particular antibody.
