Fig 7.
Cytochrome b5 (b5) and b5 reductase (b5R) protein expression in liver microsomes of guinea pigs, measured using immunoblotting. All densitometry readings were normalized to ß-actin as a loading control. (Upper panel): b5 expression was significantly decreased in combined AA and GSH deficient guinea pigs (group 2) compared to anti-oxidant replete guinea pigs (group 1; P = 0.01). (Lower panel): Trend toward reduction in b5R expression in deficient guinea pig liver microsomes (group 2) compared to replete guinea pigs (group 1; P = 0.10).
