Abstract: Cobalt-porphyrin (Co-P) complexes for use as anti-obesity agents, and compositions and methods related thereto. The Co-P complexes exhibit reduced redox activity compared to cobalt mesoporphyrin (Co-MP) and cobalt protoporphyrin (Co-PP), which alleviates the deleterious effects associated with administration of Co-P associated with oxidative stress, particularly in the context of injection site toxicity.

Abstract: The invention provides methods for screening for agents that modulate mitochondrial function and in particular mitochondrial regulation of intracellular calcium. The methods may be used to detect agents that bind to a mitochondrial calcium uniporter and may also detect inhibitors or uncouplers of mitochondrial respiration. Agents identified using the screens provided herein have application in the prevention and treatment of a variety of diseases associated with abnormal mitochondrial function.
Abstract: Compositions and methods are provided for identifying agents that alter mitochondrial membrane permeability transition. The screening methods generally detect agents that alter the interaction between the mitochondrial adenine nucleotide translocator and cyclophilin D. Such agents may be used, for example, in the treatment of a variety of conditions associated with altered mitochondrial function.

Abstract: A computer implemented glucose utilization defect (GUD) risk assessment system and method screens individuals for GUD risk based upon their mitochondrial DNA sequence. A data input receives sample data, which is compared by a deviation determiner against the standard mitochondrial DNA reference to generate a binary output sequence containing difference positions indicating deviations between the sample data and the standard reference. A deviation analyzer then assesses GUD risk by analyzing the binary sequence output with respect to ranges of mitochondrial DNA positions as identified by pre-screen ranges stored in a pre-screen ranges database and GUD ranges stored in a GUD ranges database. The GUD ranges found in the GUD database are further determined by a reference string analysis method or a branch point analysis method performed by the GUD risk assessment system and method.
Abstract: Compositions and methods based on determination of single nucleotide polymorphisms in mtDNA or homoplasmic mtDNA mutations are provided that are useful for detecting the presence or risk of diseases, determining the haplogroup of an individual, and establishing genetic relationships between individuals for genealogical and forensic purposes.
Abstract: The present invention relates to improved diagnostic methods for early detection of a risk for developing type 2 diabetes mellitus in humans, and screening assays for therapeutic agents useful in the treatment of type 2 diabetes mellitus, by comparing the levels of one or more indicators of altered mitochondrial function. Indicators of altered mitochondrial function include enzymes such as mitochondrial enzymes and ATP biosynthesis factors. Other indicators of altered mitochondrial function include mitochondrial mass, mitochondrial number and mitochondrial DNA content, cellular responses to elevated intracellular calcium and to apoptogens, and free radical production. Methods of treating, and of stratifying, human patients as such methods relate to disclosed indicators of altered mitchondrial function are also provided.
