Pioglitazone, Neet Family Proteins, And Galactose Modulation Of Liver Cell Bioenergetics, David F. Grimm
Undergraduate Honors Theses
MitoNEET was discovered through interactions with a labeled and photoactive derivative of pioglitazone (pio), a drug used to increase peripheral insulin sensitivity. Its unique coordination of a [2Fe-2S] cluster by three cysteine residues (Cys-72, Cys-74, and Cys-83) and one histidine (His-87) gives this cluster both stability and the ability to be donated to acceptor proteins. These qualities allow mitoNEET to participate in a diversity of biological functions. Functions of mitoNEET and the consequences of pioglitazone (pio) treatment in human hepatocellular carcinoma (HepG2) cells cultured in glucose or galactose-based medium were examined by respiration and proliferation studies. Pio treatment decreased complex …

Mitoneet: Reduction In Insulin Resistance Through Ameliorated Oxidative Stress?, Nicolas A. Ferry
Undergraduate Honors Theses
MitoNEET is a mitochondrial iron-sulfur protein with poorly-understood functions. Proposed functions of mitoNEET include regulating of oxidative capacity, reactive oxygen homeostasis, and other possible roles. Investigating the interactions of mitoNEET with other proteins might help identify functional roles of this protein. MitoNEET was discovered in 2004 to identify physiological targets of pioglitazone hydrochloride, a drug that is commonly used to treat type-2 diabetes. Type-2 diabetes is a metabolic disease and, although the exact pathology is complex, the role of the mitochondrion in cellular energy production and glucose oxidation indicates that this organelle has a role in type-2 diabetes. Because of …
