| Outline of Final Research Achievements |
In this study, we investigated the function of TAB182, which is a binding protein of poly(ADP-ribose)polymerase tankyrase, and the involvement of TAB182 dysfunction in the regulation of cancer cells migration and invasion. 1) TAB182 depletion activated the ROCK-LIMK pathway, which is overexpressed in various cancer cells, and enhanced cancer cell migration and invasion. Tankyrase overexpression also activated the ROCK-LIMK pathway without depletion of TAB182. 2) To investigate the involvement of TAB182 expression changes in the clinical cancer setting, we performed tissue microarray-based immunohistochemistry. Among various cancers, TAB182 expression was significantly lower in the area of invasion than that of non-invasion in pancreatic cancer.
