Table 1. ALDH2 protein production in the oesophagus of Aldh2 ^+/+ and Aldh2 ^–/– mice treated with or without ethanol drinking.

Groups	ALDH2 level
Groups	Negative	Positive
Aldh2^+/+ mice
Water	10	0
Ethanol	4	6
Aldh2^–/– mice
Water	10	0
Ethanol	10	0

We defined positive of ALDH2 protein levels when more than 50% of the cells were stained with anti-ALDH2 antibody in the basal and parabasal layers of the oesophageal epithelium. Ethanol drinking induced ALDH2 in the oesophageal epithelium in 6 out of 10 Aldh2^+/+ mice, whereas there was no induction in the water group of Aldh2^+/+ mice (p = 0.011 by Fisher’s exact test).
