Outline of Final Research Achievements |
We determined the microRNA expresssion profiles in normal pnacreas tissues, PanIN tissues, and pancreatic carcinoma tissues. We found taht miR125b is increasing proportionally to the pancreatic carcinogenetic steps. In addition, miR125b trasnlocated into the nucleus when culturing the cells in three dimension and we found Galectin 3 binds to the miR125b, which may be involved in the translocation of this microRNA.Furthermore, miR125b in thenucleus was involved in the splicing of mRNAs dependeing on the sequences. These findings may be related with the pancreatic carcinogenesis by a novel pathway.
