The “Goldilocks Zone� from a redox perspective—Adaptive vs. deleterious responses to oxidative stress in striated muscle
Alleman, Rick J.; Katunga, Lalage Adalaide; Nelson, Margaret A. M.; Brown, David A.; Anderson, Ethan (2014-09)Consequences of oxidative stress may be beneficial or detrimental in physiological systems. An organ system's position on the “hormetic curve” is governed by the source and temporality of reactive oxygen species (ROS) ... -
EXPLORING THE ROLE OF ELEVATED LIPID PEROXIDATION AND GLUTATHIONE PEROXIDASE 4 IN METABOLIC SYNDROME AND CARDIAC REMODELING IN OBESITY
Katunga, Lalage Adalaide (5/16/2016)Cardiovascular disease continues to be a leading cause of global mortality. Metabolic perturbations including obesity, hyperlipidemia and type II diabetes arising from a western style diet and a more sedentary lifestyle ... -
Monoamine Oxidase is a Major Determinant of Redox Balance in Human Atrial Myocardium and is Associated With Postoperative Atrial Fibrillation
Anderson, Ethan; Efird, Jimmy T.; Davies, Stephen W.; O'Neal, Wesley T.; Darden, Timothy M.; Thayne, Kathleen A.; Katunga, Lalage Adalaide; Kindell, Linda C.; Ferguson, T. Bruce; Anderson, Curtis A.; Chitwood, W. Randolph; Koutlas, Theodore C.; Williams, J. Mark; Rodriguez, Evelio; Kypson, Alan P. (2014-02)BACKGROUND: Onset of postoperative atrial fibrillation (POAF) is a common and costly complication of heart surgery despite major improvements in surgical technique and quality of patient care. The etiology of POAF, and ... -
Novel role for thioredoxin reductase-2 in mitochondrial redox adaptations to obesogenic diet and exercise in heart and skeletal muscle
Fisher-Wellman, Kelsey H.; Mattox, Taylor A.; Thayne, Kathleen; Katunga, Lalage Adalaide; La Favor, Justin D.; Neufer, P. Darrell; Hickner, Robert C.; Wingard, Christopher J.; Anderson, Ethan (2013)Increased fatty acid availability and oxidative stress are physiological consequences of exercise (Ex) and a high-fat, high-sugar (HFHS) diet. Despite these similarities, the global effects of Ex are beneficial, whereas ... -
Obesity in a model of haploinsufficiency uncovers a causal role for lipid-derived aldehydes in human metabolic disease and cardiomyopathy
Katunga, Lalage Adalaide; Gudimella, Preeti; Efird, Jimmy T.; Abernathy, Scott; Mattox, Taylor A.; Beatty, Cherese; Darden, Timothy M.; Thayne, Kathleen A.; Alwair, Hazaim; Kypson, Alan P.; Virag, Jitka A. I.; Anderson, Ethan (2015-04)Lipid peroxides and their reactive aldehyde derivatives (LPPs) have been linked to obesity-related pathologies, but whether they have a causal role has remained unclear. Glutathione peroxidase 4 (GPx4) is a selenoenzyme ... -
Potential for Improved Glycemic Control with Dietary in Patients with Insulin Resistance and Pre-Diabetes
Efird, Jimmy T.; Choi, Yuk Ming; Davies, Stephen W.; Mehra, Sanjay; Anderson, Ethan; Katunga, Lalage Adalaide (2014-02)Bitter Melon (Momordica charantia) is a widely used traditional remedy for hyperglycemia. While the medicinal properties of this plant have been studied extensively using in vitro and animal models, the clinical efficacy ... -
Smoking and dietary inadequacy among Inuvialuit women of child bearing age in the Northwest Territories, Canada
Kolahdooz, Fariba; Mathe, Nonsikelelo; Katunga, Lalage Adalaide; Beck, Lindsay; Sheehy, Tony; Corriveau, Andre; Sharma, Sangita (2013)Objective The prevalence of smoking in Aboriginal Canadians is higher than non-Aboriginal Canadians, a behavior that also tends to alter dietary patterns. Compared with the general Canadian population, maternal smoking ...
