Altered metabolism has been implicated in the pathogenesis of inflammatory diseases. NADPH oxidase 4 (NOX4), a source of cellular superoxide anions, has multiple biological functions that may be of importance in inflammation and in the pathogenesis of human metabolic diseases, including diabetes. However, the mechanisms by which NOX4-dependent metabolic(More)
BACKGROUND & OBJECTIVES Chromatin structure is the single most important feature that distinguishes a cancer cell from a normal cell histologically. Chromatin remodeling proteins regulate chromatin structure and high mobility group A (HMGA1) proteins are among the most abundant, nonhistone chromatin remodeling proteins found in cancer cells. These proteins(More)
OBJECTIVE Although participatory methods have become increasingly popular, people with lived experience of mental illness and homelessness have been historically excluded from service planning and research. To better plan for meaningful inclusion of consumers, this study examines lessons learned from the People with Lived Experience Caucus in the Toronto(More)
Cellular metabolism can impact cell life or death outcomes. While metabolic dysfunction has been linked to cell death, the mechanisms by which metabolic dysfunction regulates the cell death mode called necroptosis remain unclear. Our study demonstrates that mitochondrial oxidative phosphorylation (OXPHOS) activates programmed necrotic cell death(More)
OBJECTIVES Although uterine cancer is the fourth most common cause for cancer death in women worldwide, the molecular underpinnings of tumor progression remain poorly understood. The High Mobility Group A1 (HMGA1) gene is overexpressed in aggressive cancers and high levels portend adverse outcomes in diverse tumors. We previously reported that Hmga1a(More)
The successful treatment of acute decompensated heart failure continues to evolve with an increasing utilization of nondurable mechanical support devices. Indications for acute support have broadened to include their use as a bridge to recovery or decision (for durable ventricular assist devices [VADs] or heart transplant). Available devices have improved(More)
Daily treatment of rats with the thymothyroid hormone leucogenenol after their immunosuppression with anti-lymphocyte globulins causes the rats to regain their immunocompetency after 7 days of treatment, in contrast to well over a month, which is required for untreated controls. Immunocompetency was mesured by the ability of the rat to respond to the(More)
