CR increases the activities of NADH-AFR reductase and NQO1 in brain PMs during aging. The PM fractions isolated from rat brains (A and C) and SH-SY5Y cells cultured with AL or CR serum (B and D) were used to measure activity and expression levels of NADH-AFR reductase (A and B) and NQO1 (C and D). Open bars, AL; filled bars, CR. Values are the means ± SEM; n = 4 (rat brains) or 6 (SH-SY5Y cells). ∗, P < 0.01 compared with the value for 6-month-old rats; #, P < 0.01 compared with the AL value for the same age group; ⋀, P < 0.01 compared with the value for cells cultured with AL serum.
