Interestingly, mice treated with ALDH2 siRNA alone also exhibited significantly retarded tumor progression (p < 0.01, Student's t‐test; Figure 5P,R,S; Figure S4F,G, Supporting Information), and improved overall survival (p < 0.001, Student's t‐test; Figure 5S), compared with the control group. The gene discussed is ALDH2; the disease is neoplasm.
