【Abstract】 Objective: To investigate the genes differentially expressed in lung cancer and determine some lung cancer associated genes which can be used for diagnosing and treating lung cancer. Methods: cDNA microarray chips containing numerous cDNAs were used to investigate the gene expression pattern of samples of human lung cancer. Results: Three hundred and seventy genes expressed in lung cancer were screened out, comprising 146 known genes, 224 unknown genes, among these genes, up and down regulated genes were 107 and 263, respectively. Conclusion: The analysis of gene expression pattern of tumor based on cDNA microarray can realize high throughput screening of the genes associated with the lung cancer. [更多还原
