The pathological events initiating diabetic cardiac changes in response to chronic hyperglycemia and hyperinsulinemia remain unclear. Due to the high metabolic activity of the heart, and its sensitivity to acute changes in oxygen and substrate flux, mitochondrial dysfunction has been proposed as...

Eukaryotic cells are characterized by the presence of membrane-bound organelles. Close proximity between organelles has been observed for decades, but only recently we have really started to understand the importance of these contacts for cellular function. These contacts consist of areas of...

Multiple sources suggest that insulin resistance and derangements of cardiac metabolism are among the earliest signs of type-2 diabetes detected in the heart. Unfortunately, limited evidence reflects early changes in cardiac mitochondrial metabolism linked to the development of this disease....

Deregulated TNF signaling with elevated or decreased levels of TNF-induced apoptosis causes numerous inflammatory and cancerous diseases. Thus, there is a clear need to identify cellular proteins that regulate cell fate in the presence of TNF. RNA interference technology provides an excellent...

Background Adipose tissue mitochondria have been implicated as key mediators of systemic metabolism. We have shown that IL-6 activates AMPK, a mediator of mitochondrial biogenesis, in adipose tissue; however, IL-6−/− mice fed a high fat diet have been reported to develop insulin resistance. These...

Impact of conventional fractionated RT to pelvic lymph nodes and dose-escalated hypofractionated RT to prostate gland using IMRT treatment delivery in high-risk prostate cancer
DownloadFall 2009
Prostate cancer is the most common cancer among Canadian men. The standard treatment in high-risk category is radical radiation, with androgen suppression treatment (AST). Significant disease progression is reported despite this approach. Radiation dose escalation has been shown to improve...

Insulin signaling, mitochondrial DNA copy number regulation and aging in Caenorhabditis elegans
DownloadFall 2010
Mitochondrial dysfunction is considered as a key mechanism of aging but little is known about the impact of mitochondrial biogenesis. Mitochondrial DNA (mtDNA) copy number control is an important aspect of mitochondrial biogenesis and is highly regulated in eukaryotic organisms. By studying mtDNA...

Investigating Radiation in Combination with Oncolytic Vaccinia Virus to Improve the Treatment of Glioblastoma
DownloadFall 2023
Glioblastoma (GBM) is a malignant and immune-suppressed brain cancer that remains incurable despite the current standard of care. Radiotherapy is a mainstay of GBM treatment, however invasive cancer cells outside the irradiated field and radioresistance preclude complete eradication of GBM cells....

Investigation of transcriptional and translational regulation of the Neurospora crassa alternative oxidase
DownloadFall 2018
Mitochondria are organelles found in most eukaryotes and supply the cell with the majority of its energy needs in the form of ATP. Most of the proteins needed for mitochondrial function are nuclear encoded. Therefore, mitochondria communicate their functional status to the nucleus, resulting in...
