Improvement of Analytical Conditions of Mineral Caco-2 Cell Uptake Assays
2004
Caco-2 cell mineral uptake assays are used to estimate the bioavailability of minerals from foods. The uptake of minerals by Caco-2 cells can be affected by several factors – particularly the conditions of the in vitro digestion process and the growth conditions of the cell culture. Therefore, a standardisation of the assays conditions is required to obtain reproducible results. This work determined the effect of enzyme demineralisation, the inactivation of the proteolytic activity of the digest and the replacement of distilled-deionised water by cell culture degree water. Treatment with Chelex-100 resin was applied to remove calcium, iron and zinc from pepsin and pancreatin-bile salts. Th…
Meta-analysis of 74,046 individuals identifies 11 new susceptibility loci for Alzheimer's disease
2013
Eleven susceptibility loci for late-onset Alzheimer's disease (LOAD) were identified by previous studies; however, a large portion of the genetic risk for this disease remains unexplained. We conducted a large, two-stage meta-analysis of genome-wide association studies (GWAS) in individuals of European ancestry. In stage 1, we used genotyped and imputed data (7,055,881 SNPs) to perform meta-analysis on 4 previously published GWAS data sets consisting of 17,008 Alzheimer's disease cases and 37,154 controls. In stage 2, 11,632 SNPs were genotyped and tested for association in an independent set of 8,572 Alzheimer's disease cases and 11,312 controls. In addition to the APOE locu…
