Figure 2. Analysis of APOE mRNA expression in normal and gastric cancer (GC) tissues from 2 public databases. APOE mRNA levels are significantly lower (P < 0.0001) in normal gastric mucosal than that in gastric cancer tissue samples in the (A) Chen (Normal = 29; Tumor = 83), (B) Cui (Normal = 80; Tumor = 80), (C) Derric (Normal = 31; Tumor = 38), and (D) Wang (Normal = 15; Tumor = 12) Gastric datasets from the Oncomine database; and (E) GSE29272 (Normal = 134; Tumor = 134) and (F) GSE54129 (Normal = 21; Tumor = 111) datasets from the GEO databases.
