Stuart JA, Bourque BM, de Souza-Pinto NC, Bohr VA: No evidence of mitochondrial respiratory dysfunction in OGG1-null mice deficient in removal of 8-oxodeoxyguanine from mitochondrial DNA. Free Radic Biol Med. 2005 Mar 15;38(6):737-45.
Mice null for oxoguanine DNA glycosylase (OGG1) are deficient in 8-oxodG removal and accumulate 8-oxodG in mtDNA to levels 20-fold higher than in wild-type mice (N.C. No differences were detected in maximal (chemically uncoupled) respiration rates, ADP phosphorylating respiration rates, or nonphosphorylating rates with glutamate/malate or with succinate/rotenone. |
