Abstract:
Objective To investigate the differentially expressed genes of primary esophageal squamous cell carci-noma and of normal esophageal mucosa. Methods LCM-GMA-cDNA microarray was used to detect the mRNA from both the primary carcinoma and the corresponding esophageal epithelium in 15 cases of human esophageal squamous cell carcinoma (ESCC). After high-stringent washing, the cDNA microarray was scanned for the fluores-cent signals. Results Among the 886 target genes, 34 genes had significant difference in Ⅰ / Ⅱ and Ⅲ/Ⅳ group. Cell cycle regulators possibly promoting the growth of tumor cells were highly expressed in the early stages of ESCC, whereas adhesion molecules and extracellular matrix-related molecules possibly promoting invasiveness increased in the later stages. Conclusion More than one gene contributed to esophageal cancer. The profiles of gene expression will bring us chance to understanding the molecular mechanism of tumor progression and to support clinical treat-ment.
