Interestingly, for ALDH1A2 (Figure 4C and 4D), ALDH1A3 (Figure 4E and 4F) and ALDH1L1 (Figure 4I and 4J), high mRNA level was found to be significantly correlated to worsen OS in both gastric intestinal type adenocarcinoma and diffuse gastric adenocarcinoma, with the same trend as in all GC patients. The gene discussed is ALDH1A2; the disease is gastric intestinal type adenocarcinoma.
