Objective To explore the expression of tumor necrosis factor (TNF) mRNA, TNF and TNFR in the gallbladder mucosa which developed from hyperplasia, dysplasia to carcinoma, and to further discuss the relationship between TNF and pathogenesis of gallbladder carcinoma.Methods In situ hybridization and immunohistochemistry were used to determine TNF mRNA, TNF protein and TNFR protein expression in hyperplasia, dysplasia and carcinoma of gallbladder. Results ①No one of 20 cases of gallbladder hyperplasia was found to express TNF mRNA, while 4 of 20 (20%) cases of dysplasia and 18 of 20 (90%) cases of carcinoma were found to express TNF mRNA (P
