However, when cancer types were studied independently (namely breast, colorectal, lung and ovarian adenocarcinomas), the same positive correlation between AGR2 and AGR3 expressions and those of epithelial genes was maintained, as well as the negative correlation between AGR2 and AGR3 expressions and those of mesenchymal genes (data not shown). The gene discussed is AGR2; the disease is ovarian adenocarcinoma.
