Fig. 3. Aging exacerbates chronic-plus-binge-induced oxidative stress.
(A) Young and middle-aged mice were treated with chronic (8wks)-plus-multiple binges as described in Fig. 2. Hepatic levels of HNE adducts and protein nitration were measured by using an ELISA kit. (B) Young and middle-aged mice were treated with chronic (10d)-plus-one binge as described in Fig. 1. Immunohistochemistry for 4-HNE was performed, magnification at 200x. Values represent means ± SEM (n= 5). *P< 0.05, **P<0.01.
