Outline of Final Research Achievements |
In this study, we established coculture assay system using immortalized human esophageal epithelial cells (Het-1A) and human acute monocytic leukemia cells (THP-1)-derived macrophages to study the roles of macrophages in esophageal carcinogenesis. Coculture of Het-1A cells with THP-1-derived macrophages induced Het-1A cell proliferation/migration and phosphorylation of p38 MAP kinase. In addition, IL-6 was significantly increased in coculture supernatants. Finally, positive immunoreactivity for phospho-p38 MAP kinase and IL-6 in neoplastic cells were observed in some cases of esophageal high grade intraepithelial neoplasias.
