Booth and colleagues say that one cause is the partial blocking of translocator protein sites--sites where ADP is moved into mitochondria for recycling and ATP is moved out of the mitochondria to the cytosol.
Third, contrast nanoparticles for cell imaging will be delivered into the cytosol of mammalian cells through VNB induced cell membrane perforation.

There are numerous hypotheses that attempt to explain the aging process, considering complex physiological alterations in organisms, including: mitochondrial changes, accumulation of aberrant proteins in the cytosol, chemical damage to macromolecules, and somatic mutations.
Orally supplemented catechin (OSC) was previously shown to increase mitochondrial heme and catalase levels in rat heart blood, however, its effect in the cytosol has not been elucidated.
IDE is expressed in almost all tissues and distributed in the cytosol.
cAMP was either assumed to be released and rapidly distributed throughout the cytosol, or cAMP was assumed to be released into a near-membrane compartment in which it rapidly equilibrated and subsequent flux into the cytosol was slow.
This event triggers the release of pro-apoptotic proteins, including cytochrome C, from the mitochondrial intermembrane space to the cytosol where they activate caspases and endonucleases that initiates apoptosis.
When the influenza virus initially infects a cell, and the virus is confined in an endocytic vesicle, the viral proteins HA and M2 use the acidic environment inside the vesicle to fuse the viral lipid envelope with that of the vesicle, and then release the viral genome into the cytosol.
According to previous reports, lactate, formate, ethanol and succinate were formed in the cytosol of anaerobic fungi, and acetate, formate and [H.
Under normal physiological conditions, the cytosol, the nucleus, and the mitochondrial matrix space maintain homeostatic conditions in favor of a highly reducing environment (Cannon and Remington 2008).
