| Outline of Final Research Achievements |
In multicellular organisms, cell-cell communication is essential to maintain organ and tissue homeostasis. It was reported that cell-cell communication via gap junction was attenuated in many types of cancer. To make clear the role of gap junction in anti-cancer effect, we focused on miRNA movement between normal cells and cancer cells via gap junction in this study. We compared miRNA quantities in normal or in cancer cells before/after their communication was established using miRNA microarray method. Some of miRNA were thought to move between normal cells and cancer cells via gap junction. The roles of these miRNA in cell phenotype are under investigation.
