|title=Ferulic Acid Suppresses Amyloid [i]β[/i] Production in the Human Lens Epithelial Cell Stimulated with Hydrogen Peroxide.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/28409157
|abstract=It is well known that oxidative stresses induce the production of amyloid [i]β[/i] (A[i]β[/i]) in the brain, lens, and retina, leading to age-related diseases. In the present study, we investigated the effects of ferulic acid on the A[i]β[/i] levels in H O -stimulated human lens epithelial (HLE) SRA 01/04 cells. Three types of A[i]β[/i] peptides (A[i]β[/i] , A[i]β[/i] , and A[i]β[/i] ) were measured by ELISA, and the levels of mRNA for the expressed proteins related to A[i]β[/i] production (APP, [[BACE1]], and PS proteins) and degradation (ADAM10, NEP, and [[ECE1]] proteins) were determined by quantitative real-time RT-PCR. H O  stimulation augmented gene expression of the proteins related to A[i]β[/i] production, resulting in the production of three types of A[i]β[/i] peptides. Treatment with 0.1 [i]μ[/i]M ferulic acid attenuated the augmentations of gene expression and production of the proteins related to the secretion of three types of A[i]β[/i] peptides in the H O -stimulated HLE cells. These results provided evidence of antioxidative functions of ferulic acid for lens epithelial cells.

|title=The role of [[ECE1]] variants in cognitive ability in old age and Alzheimer's disease risk.
|pubmed-url=https://pubmed.ncbi.nlm.nih.gov/22693153
|abstract=The β-amyloid peptide may play a central role in Alzheimer's disease (AD) pathogenesis. We have evaluated variants in seven Aβ-degrading genes (ACE, [[ECE1]], [[ECE2]], [[IDE]], [[MME]], [[PLAU]], and TF) for association with AD risk in the Genetic and Environmental Risk in Alzheimer's Disease Consortium 1 (GERAD1) cohort, and with three cognitive phenotypes in the Lothian Birth Cohort 1936 (LBC1936), using 128 and 121 SNPs, respectively. In GERAD1, we identified a significant association between a four-SNP intragenic [[ECE1]] haplotype and risk of AD in individuals that carried at least one [[APOE]] ε4 allele (P = 0.00035, odds ratio = 1.61). In LBC1936, we identified a significant association between a different two-SNP [[ECE1]] intragenic haplotype and non-verbal reasoning in individuals lacking the [[APOE]] ε4 allele (P = 0.00036, β = -0.19). Both results showed a trend towards significance after permutation (0.05 < P < 0.10). A follow-up cognitive genetic study evaluated the association of [[ECE1]] SNPs in three additional cohorts of non-demented older people. Meta-analysis of the four cohorts identified the significant association (Z < 0.05) of SNPs in the ECE-1b promoter with non-verbal reasoning scores, particularly in individuals lacking the [[APOE]] ε4 allele. Our genetic findings are not wholly consistent. Nonetheless, the AD associated intronic haplotype is linked to the 338A variant of known [[ECE1]]b promoter variant, 338C>A (rs213045). We observed significantly less expression from the 338A variant in two human neuroblastoma cell lines and speculate that this promoter may be subject to tissue-specific regulation.
