Outline of Final Research Achievements

Repeat RNA, one of the non-coding RNAs which express in pancreatic cancer tissues, is expressed exclusively in the cancerous tissues. Its expression was not detected in the normal pancreas tissues. Thus, we hypothesized that this repeat RNA may be involved in the parthenogenesis of the pancreatic cancer. To clarify this, we constructed onverexpression system of this repeat RNA in culture cells. We observed deregulated chromatin division and impaired repair of the damaged DNA in cells, which may contribute to the malignant phenotype of cancer cells.
