Detection of complement C3 and factor B gene expression in normal colorectal mucosa, adenomas and carcinomas

Abstract excerpt

Local secretion of complement components in the human intestine has been previously reported. However, the cellular source has not been identified. In this study, we demonstrate complement C3 and factor B mRNA expression in the normal colonic mucosa by in situ hybridization analysis. C3 and factor B genes were found to be expressed at high levels in the epithelial cells of the lower parts of the crypts in colonic...
