Figure 2.
Aortic ALDH2 mRNA (A) and protein (B) levels of nitrate-tolerant WT, ascorbate-supplemented (Asc-suppl.), ascorbate-deficient (Asc-def.) and bortezomib-treated ascorbate-deficient Gulo(-/-) aortas relative to untreated WT controls. mRNA levels were analysed according to the 2-ΔΔCt method using cyclophilin D as reference gene. ALDH2 protein expression was analysed by immunoblotting and quantified densitometrically with band intensities of samples from untreated WT mice (applied on the same gels) set to 100%. A representative blot is shown as inset. Data are mean values ± SEM of four (A) or 6–9 (B) animals. *P < 0.05 compared with untreated (non-tolerant) WT animals. #P < 0.05 compared with ascorbate-supplemented mice.
