We also observed that ALDH2 is expressed at high level by almost all seven analyzed cancer types except for skin cancer (Fig. 8a-h), whereas the expressions of ALDH3A1 and ALDH3A2 are higher in lung, pancreatic, and esophagus cancer (Fig. 8b, g–h). The gene discussed is ALDH3A2; the disease is esophageal cancer.
