We measured ACE-2 activity by fluorogenic peptide substrate assay in mid-frontal cortex (Brodmann area 9) in a cohort of AD (n = 90) and age-matched non-demented controls (n = 59) for which we have previous data on ACE-1 activity, amyloid β (Aβ) level and tau pathology, as well as known ACE1 (rs1799752) indel polymorphism, apolipoprotein E (APOE) genotype, and cerebral amyloid angiopathy severity scores.
In a case-control study including 376 late-onset AD patients and 444 control subjects, we showed a statistically significant effect on the risk of AD of tw</span>o variants (rs4343 and rs1799752) and of the haplotype ATI (rs4343/rs4291/rs1799752) in subjects aged 73 years and above.
In a case-control study including 376 late-onset AD patients and 444 control subjects, we showed a statistically significant effect on the risk of AD of two variants (rs4343 and rs1799752) and of the haplotype ATI (rs4343/rs4291/rs1799752) in subjects aged 73 years and above.
Other variants, such as SNPs rs4291A>T located -240bp from the initiation codon, and rs4343G>A encoding a silent mutation in exon 16, were inconsistently associated with the risk of AD.
The purpose of this study was to examine the impact of two polymorphisms (rs4291A>T and rs4343G>A) in the ACE gene on the risk of Alzheimer's disease (AD), using a population-based cohort of 9294 subjects selected from the electoral rolls of three French cities (the Three-City Study).
Other variants, such as SNPs rs4291A>T located -240bp from the initiation codon, and rs4343G>A encoding a silent mutation in exon 16, were inconsistently associated with the risk of AD.
After adjustment for confounding variables, the risk of developing AD was similar whatever the genotype (rs4291 AT vs TT: OR=0.90, p=0.65; AA vs TT: OR=1.05, p= 0.84; rs4343 GA vs GG: OR=1.15, p= 0.48; AA vs GG: OR=1.25, p= 0.37).

To investigate the possible relationship between genetic risk factors and depression in AD, we assessed genetic polymorphisms reported to be associated with depression (MAOA VNTR, ACE 288bp Insertion/ Deletion, 5HTTLPR, COMT Val158Met, BDNF Val66Met, TPH1 A218C, HTR2A T102C, P2RX7 Q460R, FKBP5 rs1360780 and CRHR1 rs242941) in a cross-sectional study on 246 AD patients with or without clinically significant major depressive disorder (MDD) according to DSM-IV.
