Elucidating The Effects Of Glucose Toxicity On Tauopathy And Aging, Lukas Fluitt

Natural Sciences and Mathematics | Biological Sciences Master's Theses

Diabetes patients are at higher risk of contracting an age-related neurodegenerative disease such as Alzheimer’s disease (AD). However, the mechanisms which link these diseases are poorly understood. We hypothesize that glucose and elevated levels of the glycolysis by product advanced glycation end-products (AGEs), may be involved. AGEs accumulate with age and are elevated in both diabetic and AD patients. Diabetes is a metabolic disorder for which consumption of sugar-rich diets is a major risk factor and is central to etiology in the vast majority of cases.

We show that transgenic C. elegans expressing wild type (WT) human tau fed a …

Determining The Link Between Advanced Glycation Endproducts (Ages), Feeding, And Metabolism, Lauren Wimer

Reactive a-dicarbonyls (a-DC’s), such as methylglyoxal (MGO), are unavoidable metabolites generated during glycolysis that accumulate with age and have been linked with chronic age-related metabolic diseases such as Diabetes Mellitus. Diabetes Mellitus is generally characterized by peripheral neuropathy and sustained hyperglycemia. Chronic hyperglycemia leads to an increase in glycolysis and a downstream increase in reactive a-DC’s. The human body has a natural method of detoxifying these a-DC’s. Glycolytic cells have enzymes which can detoxify a-DC’s, but if overwhelmed, a-DC’s can accumulate and react non-enzymatically with proteins, lipids and DNA to yield a group of molecules called advanced glycation end-products (AGEs). …
