Gata6 is overexpressed in a variety of cancers, including pancreato‐biliary cancers (Kwei et al, 2008), colon cancers (Shureiqi et al, 2007; Tsuji et al, 2014), esophageal adenocarcinomas (Lin et al, 2012), breast cancers (Song et al, 2015), and adrenal tumors (Vuorenoja et al, 2007). This evidence concerns the gene GATA6 and esophageal adenocarcinoma.
