VCU Brew

VCU Brew is an innovative proposal to create a VCU branded signature beer. The Campus Connectors will present a rationale showing how this proposal will i) potentially generate revenue to benefit VCU scholarships and academic programs, ii) create opportunities for experiential learning by engaging VCU students in product development, branding, labeling, marketing, business, and awareness of responsible drinking, iii) and guide the process of partnering with local breweries to provide practical expertise and stimulate entrepreneurship initiatives that lead to distribution at VCU athletic, community and Alumni events, while increasing ties with the community and national prominence

Sorl1 as an Alzheimer's disease predisposition gene?

Alzheimer's disease (AD) is a neurodegenerative disorder characterized by progressively disabling impairments in memory, cognition, and non-cognitive behavioural symptoms. Sporadic AD is multifactorial and genetically complex. While several monogenic mutations cause early-onset AD and gene alleles have been suggested as AD susceptibility factors, the only extensively validated susceptibility gene for late-onset AD is the apolipoprotein E (APOE) epsilon4 allele. Alleles of the APOE gene do not account for all of the genetic load calculated to be responsible for AD predisposition. Recently, polymorphisms across the neuronal sortilin-related receptor (SORL1) gene were shown to be significantly associated with AD in several cohorts. Here we present the results of our large case-control whole-genome scan at over 500,000 polymorphisms which presents weak evidence for association and potentially narrows the association interval

Insulin-degrading enzyme haplotypes affect insulin levels but not dementia risk

Insulin-degrading enzyme (IDE) polymorphism is hypothesized to regulate insulin levels as well as processes involved in neuronal compromise found in dementia. We examined the association of IDE haplotypes with dementia and insulin levels in a single well-characterized cohort of Japanese-American men born between 1900 and 1919 and followed since 1965. In 1991, a fasting insulin was obtained; dementia cases were ascertained in 1991 and 1994 in a multi-stage procedure, diagnoses were made according to international guidelines. Five single-nucleotide polymorphisms were genotyped and used for haplotype analysis in a sample of 179 Alzheimer's disease cases, 104 vascular dementia cases and 516 controls nested in the total cohort. The global test for the haplotype effect on insulin levels was significant (p < 0.0001), adjusting for age, education, apolipoprotein epsilon4 status and fasting glucose. There was no association of IDE haplotypes with the risk of dementia. This study suggests IDE may be indirectly related to dementia via its regulation of insulin levels, but it is not a major gene for Alzheimer's

The MAPT H1c risk haplotype is associated with increased expression of tau and especially of 4 repeat containing transcripts

Previously we have shown that the H1c haplotype on the background of the H1 clade of haplotypes at the MAPT locus is associated with increased risk for progressive supranuclear palsy (PSP), corticobasal degeneration (CBD) and Alzheimer’s disease (AD). Here we replicated the association with AD in an additional autopsy confirmed series. We show that this haplotype increases both the expression of total MAPT transcript as well as specifically increasing the proportion of 4 microtubule binding repeat containing transcripts. We discuss these findings both in terms of the problems facing the dissection of the etiologies of complex traits and the pathogenesis of the tauopathies

A survey of genetic human cortical gene expression

It is widely assumed that genetic differences in gene expression underpin much of the difference among individuals and many of the quantitative traits of interest to geneticists. Despite this, there has been little work on genetic variability in human gene expression and almost none in the human brain, because tools for assessing this genetic variability have not been available. Now, with whole-genome SNP genotyping arrays and whole-transcriptome expression arrays, such experiments have become feasible. We have carried out whole-genome genotyping and expression analysis on a series of 193 neuropathologically normal human brain samples using the Affymetrix GeneChip Human Mapping 500K Array Set and Illumina HumanRefseq-8 Expression BeadChip platforms. Here we present data showing that 58% of the transcriptome is cortically expressed in at least 5% of our samples and that of these cortically expressed transcripts, 21% have expression profiles that correlate with their genotype. These genetic-expression effects should be useful in determining the underlying biology of associations with common diseases of the human brain and in guiding the analysis of the genomic regions involved in the control of normal gene expression
