BAX and gastric adenocarcinoma: In line with this, differential expression analysis of the microarray GSE264263 dataset revealed a lower BAX expression level in the gastric adenocarcinoma AGS cell line infected with Helicobacter pylori when compared with uninfected AGS counterparts; in that case, the difference was statistically significant (log2FC = −0.45; padj = 0.0037) (Figure 2).
