mitochondria play key roles in many cell functions including energy production, fatty acid metabolism, pyrimidine biosynthesis, calcium homeostasis, and aging. they also regulate crucial signaling cascades such as apoptosis and oxidative stress. the proteome is often used to investigate the functional correlations on protein levels. based upon the human, genome there is estimated 2000 to 2500 a...

aim : the aim of this study was to evaluate and compare three available methods for mitochondrial isolation from a human cell line to predict the best method for each probable application.   background : organelle isolation is gaining importance in experimental laboratory settings. mitochondrial dysfunction may affect tumorgenesis process. there are some evidences that transplantation of health...

The ultrastructure, function, and physical and chemical properties of mitochondria have become important issues in scientific research. Current mitochondrial isolation methods mainly rely on the physical and chemical properties of mitochondria. Our team presents a fast and reliable new isolation method based on magnetic nanoparticles binding with ...

Objective(s): Arsenic, a toxic metal in drinking water and butyric acid (BA) is a free fatty acid found in many foods. These two can induce oxidative stress in some tissues. The present study investigated the protective effect of metformin against toxicity induced by Arsenic (As) and BA in isolated mice liver mitochondria and pancreatic islets. Materials and Methods: In this study, liver mitoch...

Damaged mitochondria can be selectively eliminated by mitophagy. Although two gene products mutated in Parkinson's disease, PINK1, and Parkin have been found to play a central role in triggering mitophagy in mammals, how the pre-autophagosomal isolation membrane selectively and accurately engulfs damaged mitochondria remains unclear. In this study, we demonstrate that TBC1D15, a mitochondrial R...

Proteomic profiling of mitochondria has the potential to provide insights into mitochondrial functions associated with aging, various metabolic states, and diseases such as cancer, diabetes, and cardiovascular disease [1]. Rapid and reproducible isolation of intact mitochondria is crucial for efficient enrichment and subsequent proteomic analysis of low-abundance mitochondrial proteins [2]. Her...

For an adequate evaluation of mitochondria from diseased hearts, basic characteristics of isolation, storage, media, ultrastructure and type of assay were first determined using mitochondria from normal animals. A proteinase procedure yielded mitochondria from small laboratory animals, with low respiratory control and marked permeability changes. The isolation medium yielding the most stable mi...
