Analysis of MUC4 mucin expression in lung carcinoma cells and its immunogenicity

Abstract

MUC4 protein expression was elevated in lung carcinoma tissues because of the increase in its mRNA expression and deglycosylation on its core. This mucin is sufficiently immunogenic to elicit humoral and cellular immunity specific for MUC4 in patients with malignant disease. MUC4 is expected to be useful as a target antigen in immunotherapy for patients with carcinoma of the lung.
