Annexin A1 protein expression was positively correlated with its gene expression profile; correlation coefficients were r = 0.786, P = 0.007 in esophageal cancer, r = 0.689, P = 0.006 in gastric carcinoma, r = 0.739, P = 0.058 in small intestine carcinoma, and r = 0.470, P = 0.013 in colorectal carcinoma. This evidence concerns the gene ANXA1 and small intestine carcinoma.
