The Effects Of Resistance Exercise Training On Insulin Resistance Development In Female Rodents With Type 1 Diabetes, Mitchell James Sammut
The Effects Of Resistance Exercise Training On Insulin Resistance Development In Female Rodents With Type 1 Diabetes, Mitchell James Sammut
Electronic Thesis and Dissertation Repository
The etiology of insulin resistance (IR) development in type 1 diabetes mellitus (T1DM) remains unclear; however, impaired skeletal muscle metabolism may play a role. While IR development has been established in male T1DM rodents, female rodents have yet to be examined in this context. Resistance exercise training (RT) has been shown to improve IR and is associated with a lower risk of hypoglycemia onset in T1DM compared to aerobic exercise. Additionally, the molecular mechanisms mediating RT-induced improvements in insulin sensitivity remain unclear. Therefore, the purpose of this study was to investigate the effects of RT on IR development in female …

Characterization And Modulatory Influence Of Pyruvate Kinase Muscle Isoforms 1 And 2 Within The Murine Pluripotent Continuum, Joshua G. Dierolf
Electronic Thesis and Dissertation Repository
Mouse embryonic stem cells (mESCs) and mouse epiblast stem cells (mEpiSCs) represent opposite ends of a pluripotency continuum, respectively referred to as naïve and primed pluripotent states. A third, recently discovered intermediate state has been described as the ‘formative state’. Metabolism has been traditionally regarded as a by-product of cell fate; however, recent evidence now supports metabolism as promoting stem cell fate. Pyruvate kinase muscle isoforms 1 and 2 (PKM1 and PKM2) catalyze the final, rate limiting step of glycolysis generating adenosine triphosphate (ATP) and pyruvate; however, the precise role(s) of these isozymes in naïve, formative, and primed pluripotency is …
