Disruption of mitochondrial fitness in human preadipocytes by fatty acids
(East Carolina University, 2013)
Adipose tissue lies at the core of energy metabolism, by not only releasing and taking up fatty acids (FA) according to the individuals overall surplus or deficit of energy, but also signaling other tissues to regulate ...
EXPLORING DIFFERENCES IN INDIVIDUAL SUSCEPTIBILITY TO LIPOTOXICITY AND THE UNDERLYING MECHANISMS IN THE MITOCHONDRIA OF PRIMARY PREADIPOCYTES
(East Carolina University, 2018-07-17)
Prolonged exposure to fatty acids (FAs), at levels normally seen during fasting, can be cytotoxic in vulnerable cells including preadipocytes. Prior work from our laboratory has shown that FAs cause mitochondrial inner ...
Novel role for thioredoxin reductase-2 in mitochondrial redox adaptations to obesogenic diet and exercise in heart and skeletal muscle
(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 ...
MuRF1 activity is present in cardiac mitochondria and regulates reactive oxygen species production in vivo
(2014-06)
MuRF1 is a previously reported ubiquitin-ligase found in striated muscle that targets troponin I and myosin heavy chain for degradation. While MuRF1 has been reported to interact with mitochondrial substrates in yeast ...
Discovery and investigation of a novel role for mitochondrial prohibitin in mitigating acute heart failure in endotoxic shock
(East Carolina University, 2014)
Sepsis results in more than 200,000 deaths annually and is the 10th leading cause of death in the United States (US). In spite of significant advances in medical care the mortality rate for sepsis has continued to rise. ...
