Naktide Targeted To Adipocytes Ameliorates Western Diet Induced Obesity, Rebecca D. Pratt
Theses, Dissertations and Capstones
Obesity has become a worldwide epidemic and is a major risk factor for metabolic syndrome. It is believed that cellular oxidant stress plays a key role in both the development and maintenance of obesity as well as its associated comorbidities such as diabetes, cardiovascular disease, and nonalcoholic steatohepatitis (NASH). We have previously reported that systemic administration of pNaKtide, which targets the Na/K-ATPase oxidant amplification loop was able to decrease oxidative stress and adiposity in mice fed a high fat and fructose supplemented western diet (WD). As adipocytes are believed to play an active role in the development of obesity and …

Inhibition Of Elongation Factor 1a-1 Activity And Hepatic Lipotoxicity, Alexandra Margaret Anne Hetherington
Electronic Thesis and Dissertation Repository
Elongation factor 1A-1 (eEF1A-1) was previously identified as a mediator of fatty acid-induced cell death (lipotoxicity) downstream of endoplasmic reticulum (ER) stress. Furthermore, inhibition of the peptide elongation activity of eEF1A-1 with the cyclic depsipeptide didemnin B (DB) diminishes ER stress and lipotoxicity in cultured hepatocytes. Since ER stress is involved in nonalcoholic fatty liver disease (NAFLD), it was hypothesized that administration of DB to obese mice with NAFLD would reduce hepatic lipotoxicity. Treatment with DB for one week improved several parameters associated with hepatic lipotoxicity and modestly decreased food intake without evidence of illness. Liver triglycerides and protein markers …
