Microarray gene chip analysis and action of yiyiren oil on anti-tumor metastasis reactive gene / 中国组织工程研究

ABSTRACT

BACKGROUND: From yiyiren oil is extracted kanglaite injection that has been extensively used against lung cancer for its function against cancer. It is revealed that kanglaite injection inhibits many strains of cancer cells including LA795 metastatic lung cancer. Genechip is used here for detection of metastasis reactive differentially expressed genes in mice that carry LA795 metastatic lung cancer.OBJECTIVE: To detect the metastasis reactive diferentially expressed genes with genechip technology in metastatic cancer carrying mice that treated with y iyiren oil injection(kanglaite injection).DESIGN: It was a controlled trial with mice as subjects.SETTING: Oncology Department of Xiyuan Hospital Affiliated to China Academy of Traditional Chinese Medicine.MATERIALS: The trial was conducted from February through August 2003. Forty mice were implanted with T739 strain lung adenocarcinoma cells and were randomly and averagely assigned into 2 groups.METHODS: mRNA probe was made from cancer sample of the mice. ScanArray 3000 scanner was used to scan the fluorescence signal in cDNA expression genechip that contained 4096 mouse genes in order to detect the differentially expressed genes.MAIN OUTCOME MEASURES: The differentially expressed genes in the two groups of mice.RESULTS: The mice genes expressed differentially between the kanglaite injection group and control group. After examination being repeated for 3 times, 27 genes presented different expression; 25 genes expression increased in both groups and 2 genes decreased. Among these differentially expressed genes, 12 genes were of the mouse muscle cDNA. It was also observed that 6 genes might be associated with the occurrence and development of tumor.CONCLUSION: Gene expression spectrum genechip is useful in effectively detect the relevent differentially expressed gene induced by kanglaite injection.
