Expression of Cdx2 and Claudin-2 in the Multistage Tissue of Gastric Carcinogenesis

In this paper, we investigated Cdx2 and claudin-2 expression in pathological paraffin tissues of sinus ventriculi from gastroscopic biopsy to determine the correlation between the expressions of these 2 genes during gastric carcinogenesis by immunochemical ABC technique. Altogether, we analyzed 108 chronic superficial gastritis, 55 chronic atrophic gastritis, 109 intestinal-type metaplasia, 93 dysplasia and 52 gastric intestinal-type...
