Analysis of RNA-seq data from the TCGA consortium revealed that both the GATA4 and GATA6 transcripts are on average expressed at significantly higher levels in gastric tumors compared to a collection of solid cancer types (Figure 1A), with the exception of hepatocellular carcinoma tumors, in which GATA4 levels were not significantly different compared to gastric tumors (Supplementary Table S1). The gene discussed is GATA4; the disease is gastric neoplasm.
