| Outline of Final Research Achievements |
The expression levels of lncRNA (HOTAIR, Malat1, MEG3 and GAS5) were analyzed in cancer tissue and adjacent normal epithelium of patients with gastrointestinal cancer by real-time PCR. HOTAIR was up-regulated in cancer tissue compared with adjacent normal epithelium in patient with esophageal cancer, gastric cancer and colorectal cancer. However, the expression levels of Malat1, MEG3, GAS5 were not significantly changed between cancer tissue and normal epithelium. There was no significant correlation between the expression of these lncRNAs and patient survival. Then, we tried to analyze the expression of lncRNA in serum of patient with colorectal cacner. However, we could not quantify the expression because the expression levels was too low.
In summary, we could not identify specific lncRNAs as hopeful biomarker or therapeutic target in gastrointestinal cancer.
