Looking beyond the standard genome-wide association study: Biologically-motivated methodological approaches to discover novel genetic variants associated with complex human traits and disease
DownloadFall 2018
The standard approach for testing associations between common single nucleotide genetic variants (referred to as single nucleotide polymorphisms or SNPs) and disease entails testing disease associations for each SNP in the genome individually. This “hypothesis-free” approach has identified...

Malignant gliomas (MG) are the most common and aggressive brain cancers. FABP7 is an intracellular lipid trafficking molecule whose expression correlates with reduced MG patient survival. FABP7 has been shown to increase the migratory behaviour of MG cells. Moreover, the migratory behaviour of...

MicroRNA Buffering and Altered Variance of Gene Expression in Response to Salmonella Infection
Download2014
Plastow, G. S., Bao, H., Kommadath, A., Guan, L. L., Tuggle, C. K., Stothard, P.
One potential role of miRNAs is to buffer variation in gene expression, although conflicting results have been reported. To investigate the buffering role of miRNAs in response to Salmonella infection in pigs, we sequenced miRNA and mRNA in whole blood from 15 pig samples before and after...

If all cells in a multicellular organism contain exactly the same genetic information, the question arises of how tissue types with distinct gene expression profiles are formed and maintained over the life of the organism. These different temporal and spatial gene expression patterns are thought...

Glioblastoma (GBM), classified as WHO grade IV astrocytoma, is the most common and lethal adult primary brain tumour. Despite recent advances in treatment, GBM prognosis remains largely unchanged with most patients succumbing to the disease within ~15 months of diagnosis. This dismal outcome can...

Malignant glioma (MG), comprised of grade III (anaplastic astrocytoma) and grade IV (glioblastoma) astrocytoma, is the most common adult brain tumour, with an incidence of ~4 in 100 000 people. Despite aggressive treatment with surgery, radiation, and chemotherapy, survival remains dismal, with...

Study of calcineurin interaction with inhibitor-1 and natural products. Towards novel calcineurin inhibitors
DownloadSpring 2012
Calcineurin (CaN) is an eukaryotic Ser/Thr protein phosphatase that plays an important role in lymphocyte activation. Inhibition of CaN leads to immune system suppression, a necessary procedure in organ transplantation. However, use of CaN inhibitors results in toxic side effects. The search for...

Early mammalian development cannot progress without targeted temporal and spatial expression of genes. Changing the accessibility of DNA to transcriptional machinery is one critical way gene expression is controlled. This process, known as chromatin remodeling, is vital for formation of the...

Transcriptional regulation of von Willebrand Factor gene in response to hypoxia and in cancer cells
DownloadFall 2016
Von Willebrand Factor (VWF) is a pro-coagulant, glycosylated protein that is exclusively expressed in endothelial cells and megakaryocytes. An acute phase protein, VWF is upregulated or released from activated or injured endothelial cells. In addition, it is a carrier for factor VIII that...
