Identifying a Prognostic Test in Follicular Lymphoma Using a Tissue Microarray and Immunohistochemistry
(2008-07-08)Follicular lymphoma (FL) is an attractive model for discovering biomarkers and elucidating mechanisms of tumour progression. We hypothesized that alterations in the expression of proteins with known roles in cancer biology ... -
Identifying the Molecular Mechanism of TAZ-Induced Lung Tumorigenesis
(2014-09-17)The transcriptional co-activator with PDZ-binding domain (TAZ) is a transcriptional co-activator and downstream component of the tumor suppressor Hippo pathway that plays critical roles in organ size control, stem cell ... -
An immune modulatory role for the fes proto-oncogene
(2015-07-21)The Fes protein tyrosine kinase is abundantly expressed in phagocytic immune cells, including tumor associated macrophages. Fes knockout mice (fes-/-) display enhanced sensitivity to LPS, and this was shown to be associated ... -
Impact of Androgen Deprivation Therapy on the Gastrointestinal Microbiota of Prostate Cancer Patients
Background: Prostate Cancer (PCa) is one of the leading causes of cancer in men. Androgen deprivation therapy (ADT), the standard of care for advanced PCa, has been associated with developing the metabolic syndrome. The ... -
In Vitro Characterization of the Function of ABCA1: Effects of Naturally Occurring Mutations
(2010-02-12)The ATP-binding cassette (ABC) transporter, ABCA1, plays a pivotal role in reverse cholesterol transport, which is the elimination of excess sterols from peripheral cells and their transport to the liver for elimination. ... -
The Influence of Sequence Variation on von Willebrand Factor Biosynthesis, Proteolytic Processing and Clearance
(2012-08-07)Von Willebrand factor (VWF) promotes platelet adhesion and aggregation at sites of vascular damage. This function is directly related to the multimer size of VWF. The VWF-specific metalloprotease ADAMTS13 decreases VWF ... -
Integrating Phospholipid and Cyclic Nucleotide Signaling: Roles of Phosphodiesterases as Enzymes and Tethers
(2011-06-28)Cells of the cardiovascular system translate incoming extracellular signals from hormones and drugs through binding of cell surface receptors, and activation of intracellular signaling cascades allowing modulation of ... -
Investigating the Genetic Basis of Type 3 of Von Willebrand Disease (VWD)
(2013-10-18)von Willebrand Disease (VWD) is the most common inherited bleeding disorder in humans, resulting from quantitative or qualitative deficiencies of von Willebrand factor (VWF). Type 3 VWD is the rarest and most severe form ... -
Investigating the relationship between the RET receptor, Cbl and ARHGEF7 in downregulation of RET
(2008-07-15)The RET proto-oncogene encodes a receptor tyrosine kinase (RTK), with two major isoforms, RET9 and RET51, which differ in their C-termini, and therefore recruit different signaling complexes. RET plays an important role ... -
Investigating the Role of cAMP-Signaling in the Regulation of Vascular Endothelial Cell Adaptive Responses to Fluid Shear Stress
(2016-05-11)The circulating blood exerts a force on the vascular endothelium, termed fluid shear stress (FSS), which directly impacts numerous vascular endothelial cell (VEC) functions. For example, high rates of linear and undisturbed ... -
Investigating the role of PDE4D7 in vascular smooth muscle cell migration
(2015-08-31)Inhibiting the maladaptive migration of vascular smooth muscle cells (VSMCs) in injured blood vessels can help to reduce the development of intimal lesions in vascular diseases such as atherosclerosis and restenosis. Cyclic ... -
Investigating the role of von Willebrand factor (VWF) in angiogenesis
Gastrointestinal bleeding from angiodysplasia can be a debilitating problem for patients with defective or deficient von Willebrand factor (VWF). Studies have pointed to a regulatory role for VWF in vessel formation however, ... -
Investigation of Private Well Water Quality in Southeastern Ontario Using Geographic Information Systems and Molecular Microbial Source Tracking Tools
(2014-06-02)In Canada, as in many other affluent nations, private well water consumers remain at risk for gastrointestinal (GI) illness due to fecal contamination of groundwater. There have been numerous documented outbreaks of GI ... -
Investigations into the Plasma Membrane Trafficking of Multidrug Resistance Protein 4 (ABCC4/MRP4)
(2015-09-10)Multidrug resistance protein 4 (MRP4) is a member of subfamily C of the ATP-binding cassette superfamily of membrane transport proteins. In polarized cells, MRP4 localizes to the apical or basolateral plasma membrane ... -
Itch E3 ubiquitin ligase regulates LATS1 tumour suppressor stability
(2011-04-27)The Large Tumor Suppressor 1 (LATS1) is a serine/threonine kinase and tumor suppressor found down-regulated in a broad spectrum of human cancers. It is a central player of the emerging Hippo-LATS tumour suppressor pathway, ... -
Kinome-wide CRISPR-Cas9 screen to identify kinases involved in Taxol resistance in breast cancer
(2016-08-31)Breast cancer is the most frequently diagnosed cancer in women, accounting for over 25% of cancer diagnoses and 13% of cancer-related deaths in Canadian women. There are many types of therapies for treatment or management ... -
The Mammary Epithelial Cell-Specific Role of Peroxisome Proliferator-Activated Receptor (PPAR)γ in DMBA-Mediated Breast Tumourigenesis
(2008-09-04)Breast cancer is the most commonly diagnosed cancer, and the second leading cause of cancer-related deaths, among women world-wide. Improved understanding of breast tumourigenesis may facilitate the development of more ... -
The Mammary Epithelial Contribution Of PPARγ In Breast Tumourigenesis
(2014-08-06)Previous studies with peroxisome proliferator-activated receptor (PPAR)γ heterozygous mice suggest PPARγ normally suppresses 7,12-dimethylbenz[a]anthracene (DMBA)-induced breast tumour progression, but the mechanisms and ... -
