Concurrent increase of oxidative DNA damage and lipid peroxidation together with mitochondrial DNA mutation in human lung tissues during aging--smoking enhances oxidative stress on the aged tissues.

abstract：:Oxidation of [2,3-14C]succinate carbons in the mitochondrial Krebs cycle was used as a probe to investigate the effects of insulin, epinephrine, glucagon, and 2,4-dinitrophenol (2,4-DNP) on isolated rat hepatocytes. Epinephrine, glucagon, and 2,4-DNP had a far greater stimulatory effect on 14CO2 formation from [2,3-14...
