Outline of Final Research Achievements |
To elucidate the roles of the tumor associated macrophages (TAMs) in the esophageal squamous cell carcinomas (ESCCs), up-regulated genes in the TAM-like cells through the differentiation of macrophages derived from peripheral blood monocytes by the treatment of conditioned media of ESCC cells were extracted by cDNA microarray analysis. An adhesion molecule NCAM modulated the FGF2 signaling and promoted survival and motility of TAM-like cells by associating with FGFR1. A chemokine CXCL8 induced the migration and invasion of ESCC cells through binding with its receptors CXCR1 and/or CXCR2. CSF3 was up-regulated in the immortalized esophageal squamous epithelial cell Het-1A when co-cultured with TAM-like cells. Recombinant CSF3 promoted the migration of Het-1A and induced the phospharylation of GSK3α/β and β-catenin suggesting the contribution in the early stage of the esophageal carcinogenesis.
