| Outline of Final Research Achievements |
In this project, we tried to identify long non-coding RNAs (lncRNA) associated with development of cancer cell and cancer stem cells. Moreover, we also investigated their function and regulation in molecular level. We found that expression of lnc RNA ANRIL, a lncRNA associated with cancerious self-growth, was suppressed by overexpression of activated Ras. In contrast, expression of lncRNA PANDA associated with apoptosis was upregulated. Moreover, we investigated a novel function of PANA in tumor suppression. We found that PANDA promoted stabilization of p53 protein. The result suggested that PANDA may be a tumor suppressor lncRNA.
