MitoNEET is a protein that was identified as a drug target for diabetes, but its cellular function as well as its role in diabetes remains elusive. Protein pull-down experiments identified glutamate dehydrogenase 1 (GDH1) as a potential binding partner. GDH1 is a key metabolic enzyme with emerging roles in insulin regulation. MitoNEET forms a covalent complex with GDH1 through disulfide bond formation and acts as an activator. Proteomic analysis identified the specific cysteine residues that participate in the disulfide bond. This is the first report that effectively links mitoNEET to activation of the insulin regulator GDH1.

Honors Scholar Theses
Implantable glucose sensors for Diabetes management should possess several attributes such as linearity, sensitivity, selectivity, long life time and should elicit no negative tissue response. Based on this, the UConn implantable glucose sensor team has developed a 5-layer sensor architecture that simultaneously affords the aforementioned requirements. However, the large scale production of these 5-layer sensors is inhibited by the lack of high sensor-to-sensor reproducibility. Herein, we investigate the origin of sensor-to-sensor irreproducibility and develop methodologies for large-scale fabrication of these devices.
Iapp Aggregation And Cellular Toxicity Are Inhibited By 1,2,3,4,6-Penta-O-Galloyl-Β-D-Glucose, Edward Bruno, Catalina Pereira, Karla P. Roman, Marisa Takiguchi, Pei-Yu Kao, Luiza A. Nogaj, David A. Moffet

The polyphenol, 1,2,3,4,6-penta-O-galloyl-β-D-glucose (PGG) has been found to exhibit a host of positive pharmacologic activities, including anti-cancer and anti-diabetic. Little is known about the mode of action of PGG in yielding these positive activities. We show here that PGG is a potent inhibitor of IAPP (islet amyloid polypeptide, amylin) aggregation. Preventing the initial aggregation event of IAPP is one strategy for slowing, and possibly preventing, the toxic effects of IAPP oligomeric intermediates. Equal molar ratios of PGG to IAPP substantially reduced the ability of IAPP to bind thioflavin T. Atomic force microscopy revealed that PGG prevented amyloid-based fiber formation under …

Alzheimer’s disease (AD) is the most common form of dementia, accounting for 50 to 80 percent of all dementia cases. This neurodegenerative disease leads to neuronal death and tissue loss in the brain, resulting in the slow deterioration of memory, thinking skills, and eventually even the ability perform daily tasks. While it is not a normal part of aging, AD is mostly diagnosed in people over the age of 65; thus, the main risk factor for Alzheimer’s disease is increased age, though it is most likely other additional factors also contribute (Heese & Akatsu, 2006). Neuropathological hallmarks of AD include …

[First paragraph] For most with diabetes, physical activity has a blood glucose lowering effect (1). Hypoglycemia (i.e., blood glucose < 65 mg/dL) resulting from exercise is a concern, particularly for insulin users (2).
