Fig. 1From: Epithelial CD80 promotes immune surveillance of colonic preneoplastic lesions and its expression is increased by oxidative stress through STAT3 in colon cancer cellsCD80 expression in human colonic epithelial cells. Flow cytometry was performed for surface expression of CD80 (a) and HLAabc (b) on freshly isolated colon epithelial cytokeratin+ (CK+) cells from human mucosa specimens. Median values are shown. (c) An independent study in the NCBI GEO database showed a significant upregulation of CD80 expression (mRNA) in CEC from dysplastic mucosa vs normal or neoplastic mucosa. *P < 0.05 ** P < 0.01 by Mann Whitney u testBack to article page
