A: diagram of the human stomach with general location of fundus and corpus samples. B: MA plot generated by differential gene expression analysis of the RNA sequencing (RNAseq) dataset. Differential gene expression is visualized with the fold change (log2) on the y-axis over the mean of normalized counts. The red dots represent genes with significantly different expression (P < 0.05). C: Venn diagram representing the percent of significantly different gene expression in the fundus or corpus, along with overlapping expression in both regions.
