Outline of Final Research Achievements

It has been reported that p116Rip has an ability to interact with cytoskeletal molecules such as myosin, actin, and myosin phosphatase, suggesting that p116Rip affects cell motility. However, the role of p116Rip has not been investigated well. In this study, we focused on the actin which binding to asbestos in vitro and on the role of p116Rip interacting with actin. We investigated the localization of p116Rip in lung tissues in patients with asbestos exposure and clarified the co-localization of p116Rip with EMT markers such as vimentin, β-catenin, and α-smooth muscle actin. The results suggested that p116Rip has an interaction with EMT markers and plays a role of asbestos-induced carcinogenesis.
