Delivery of drugs and macromolecules to mitochondria.

Abhijit Mukhopadhyay et al.

Advanced drug delivery reviews, 59(8), 729-738 (2007-07-31)

Mitochondria is where the bulk of the cell's ATP is produced. Mutations occur to genes coding for members of the complexes involved in energy production. Some are a result of damages to nuclear coded genes and others to mitochondrial coded

Phylogenetic differences of mammalian basal metabolic rate are not explained by mitochondrial basal proton leak.

E T Polymeropoulos et al.

Proceedings. Biological sciences, 279(1726), 185-193 (2011-06-03)

Metabolic rates of mammals presumably increased during the evolution of endothermy, but molecular and cellular mechanisms underlying basal metabolic rate (BMR) are still not understood. It has been established that mitochondrial basal proton leak contributes significantly to BMR. Comparative studies

Release of mitochondrial glutathione and calcium by a cyclosporin A-sensitive mechanism occurs without large amplitude swelling.

M K Savage et al.

Archives of biochemistry and biophysics, 315(1), 142-152 (1994-11-15)

Treatment of isolated mitochondria with calcium and inorganic phosphate induces inner membrane permeability that is thought to be mediated through a non-selective, calcium-dependent pore. The inner membrane permeability results in the rapid efflux of small matrix solutes such as glutathione

Primary causes of decreased mitochondrial oxygen consumption during metabolic depression in snail cells.

Tammie Bishop et al.

American journal of physiology. Regulatory, integrative and comparative physiology, 282(2), R372-R382 (2002-01-17)

Cells isolated from the hepatopancreas of estivating snails (Helix aspersa) have strongly depressed mitochondrial respiration compared with controls. Mitochondrial respiration was divided into substrate oxidation (which produces the mitochondrial membrane potential) and ATP turnover and proton leak (which consume it).

A new strategy to screen molecular imaging probe uptake in cell culture without radiolabeling using matrix-assisted laser desorption/ionization time-of-flight mass spectrometry.

Zhen Cheng et al.

Journal of nuclear medicine : official publication, Society of Nuclear Medicine, 46(5), 878-886 (2005-05-06)

Numerous new molecular targets for diseases are rapidly being identified and validated in the postgenomic era, urging scientists to explore novel techniques for accelerating molecular probe development. In this study, matrix-assisted laser desorption/ionization time-of-flight mass spectrometry (MALDI-TOF-MS) was investigated as
