IUBMB Life 50:279-89. 2000..This remarkable array of systems for defense; damage removal, replacement, and repair; adaptation; growth modulation; and apoptosis make it possible for us to enjoy life in an oxygen-rich environment...
Protein oxidation and 20S proteasome-dependent proteolysis in mammalian cellsR Shringarpure
Ethel Percy Andrus Gerontology Center and Division of Molecular Biology, University of Southern California, Los Angeles 90089-0191, USA
Cell Mol Life Sci 58:1442-50. 2001..Interestingly, it appears that the 20S 'core' proteasome conducts the recognition and elimination of oxidized proteins in an ATP-independent and ubiquitin-independent pathway...
Degradation of oxidized proteins by the 20S proteasomeK J Davies
Ethel Percy Andrus Gerontology Center, and Division of Molecular Biology, University of Southern California, Los Angeles 90089 0191, USA
Biochimie 83:301-10. 2001..Since these products of severe oxidative stress inhibit the 20S proteasome, they cause a vicious cycle of progressively worsening accumulation of cytotoxic protein oxidation products...

Arch Biochem Biophys 389:254-63. 2001..Third, proteasome glutathiolation seems to be a previously unknown mechanism of proteasome regulation in vivo...
Impairment of lon-induced protection against the accumulation of oxidized proteins in senescent wi-38 fibroblastsJenny K Ngo
Ethel Percy Andrus Gerontology Center, University of Southern California, Los Angeles, CA 90089 0191, USA
J Gerontol A Biol Sci Med Sci 66:1178-85. 2011..These senescent changes are similar to the effects of Lon silencing in young cells. We suggest that loss of Lon stress inducibility is part of a pattern of diminishing stress adaptability that predisposes cells to senescence...
Do RCAN1 proteins link chronic stress with neurodegeneration?Gennady Ermak
Ethel Percy Andrus Gerontology Center, Davis School of Gerontology, University of Southern California, 3715 McClintock Ave, Los Angeles, CA 90089 0191, USA
FASEB J 25:3306-11. 2011..Both inhibition of calcineurin and induction of GSK-3β contribute to accumulation of phosphorylated tau, formation of neurofibrillary tangles, and eventual neurodegeneration...
