There was a clear specificity in their co-expression pattern with AGR2: some genes were co-expressed in colon adenocarcinoma, others in breast adenocarcinoma, etc. It should be mentioned that EGFR, CD59 and VEGFA gene expressions were, in contrast, negatively correlated with AGR2 expression in breast adenocarcinomas. The gene discussed is VEGFA; the disease is colon adenocarcinoma.
