33, 1334–1346. Analyses of GWAS AD genes have highlighted a significant overrepresentation of genes found in common disease pathways such as inflammation and endocytosis (Bertram et al., 2007; Jones et al., 2010), resulting in GWAS AD genes being grouped together based on their similar functions (Rosenthal et al., 2014). (2014) observed that CLU variants influence brain activity in an additive manner in the presence of APOE E4 genotype, resulting in a reduction of temporal lobe brain activity in young, healthy individuals. Ventricular enlargement occurs in normal aging, but Alzheimer's disease (AD) leads to larger ventricular volumes (Carmichael et al., 2007a) and faster expansion rates (Carmichael et al., 2007b). However, increased clusterin levels are also found in non-proteotoxic neurological diseases, including schizophrenia, Rett syndrome and hypoxia-ischaemia, all of which share at least some underlying pathogenic processes with those found in AD, clearly indicating that the role of secreted clusterin in AD may be more complex than just that of a chaperone. This interaction is also observed in the induced prostate cancer cell line, MLLTet-sClu, where the same dose of doxycycline that was enough to induce clusterin synthesis, increases Akt and Bad phosphorylation, and reduces cytochrome C release, thus promoting cell survival (Ammar and Closset, 2008).

C., Tseng, C. J., and Sheu, G. T. (2009). The ADNI MRI protocol was selected in a data-driven manner after considerable deliberation by a group of experts in the field (Jack et al., 2008). Maps in Figures 1 and ​and22 were corrected for multiple comparisons using a false discovery rate (FDR) of 5% (q value = 0.05). (2002). Genet.

Sulfated glycoprotein-2 expression increases in rodent brain after transient global ischemia. However, the seminal work on this line of research only demonstrated that exogenous expression of a low-abundance transcript lacking exon 2 led to cytosolic localization of a GFP-fusion protein, which was also found in the nuclei of apoptotic cells (Leskov et al., 2003). The methods for surface-based image analysis have been detailed previously (Thompson et al., 2004; Ballmaier et al., 2008; Roussotte et al., 2012). (1998).
