Expression of human mucous proteinase inhibitor in respiratory tract: a study by in situ hybridizationI Van Seuningen, JP Audie, B Gosselin, JJ Lafitte and M Davril Unite 377 INSERM, l'Hopital Calmette, Lille, France. Human mucous proteinase inhibitor (MPI) is present in bronchial secretions, where it participates in the protection of lung structures against degradation by leukocyte elastase. The protein has been localized by immunohistochemical studies and immunogold labeling essentially in the serous cells of the submucosal glands and also in the surface epithelial cells of central and peripheral airways. However, until now no gene expression study has been performed at the tissue level. In this study, in situ hybridization was used to precisely study MPI mRNA expression in bronchial tissue sections with a specific radiolabeled oligonucleotide probe. By light microscopy, MPI gene expression was localized exclusively in the serous and seromucinous acini of the submucosal glands of large airways. The MPI gene was expressed in submucosal glands of normal and carcinomatous tissue sections, whereas it was not expressed in bronchial and bronchiolar surface epithelia.
