Effect of ALDH2 functional disturbance on the expression of antioxidant genes. RNA extracted from all human samples was examined to determine the expression level of several antioxidant genes. Expression of NRF2 (a, b) and PRDX1 (c, d) was significantly higher in ALDH2/ALDH2 than in the ALDH2/ALDH2*2 heterozygous samples. HMOX-1 expression showed a similar trend but the differences were non-significant (e, f)
