| Outline of Final Research Achievements |
Drug induced lung injury and acute exacerbation of idiopathic interstitial pneumonia are more frequent among Japanese people than people in other countries. The pathology of these disease is diffuse alveolar damage (DAD), and common genetic factors are assumed. We had accumulated Japanese patients with DAD. Mucin 4 (MUC4) was identified as a candidate gene, by carrying out the exome analysis about these patients and comparing with Caucasian, Chinese and healthy Japanese. Genetic polymorphisms of MUC4 among the patients with DAD and healthy subjects were analyzed, and cloned to prepare an expression vector for every genetic polymorphism of MUC4. Furthermore, primary culture cells of the bronchial epithelium were established form the resected lungs for lung cancer and the like, in order to reveal functional differences of the bronchial epithelial cells between patients with DAD and healthy subjects.
