Abstract:
OBJECTIVE To investigate the expression profile of inflammation related genes in laryngeal squamous cell carcinoma by functional gene chip technique and to probe into the role of correlative genes in pathogenesis of the laryngeal squamous cell cancer and in tumor immunity. METHODS The total RNAs were respectively extracted from two pair samples of laryngeal tumor and the normal tissue around the tumor, and then were reversely transcribed to cDNAs, then synthesized to cRNAs. The cRNAs were labeled with the hybridization probes. The probes were then hybridized with four pieces of inflammation related genes chip. It was chemiluminescently detected and the acquired image was analyzed with special software. RESULTS Forty genes were differently expressed in inflammation related gene profile of laryngeal tumor, among which 22 genes were upregulated and 18 genes were down regulated. Thirteen genes were shown differential expression in both chips with 10 upregulated genes and 3 downregulated genes. CONCLUSION The differently expressed genes in inflammation related gene chips will provide clues and theoretical foundation for the investigation of the relationship between tumor and inflammation, and also the immune pathogenesis of laryngeal tumor. Furthermore CCL-7 may have an important role in the occurrence of laryngeal cancer, and the role of immunity of the pathogenesis of laryngeal tumor needs further studied.
