| Outline of Final Research Achievements |
Cellular localization and functions of dipeptidase 1 (DPEP1), a marker of colorectal cancer, were investigated in this study. In a HCC56 cell line that expresses DPEP1 at high levels, DPEP1 was found to be localized on plasma membrane domains containing GPI-anchored protein, and at the bottom of microvilli. Suppression of DPEP1 by RNAi experiment did not affect the cell growth, but caused a vulnerability to oxidative stress, suggesting that DPEP1 might be involved in the tolerance of cancer cells against oxidative stress. Therefore, this study proposes a new mechanism involving DPEP1, which could be a target of anticancer drug development.
