Outline of Final Research Achievements |
In this study, we identified daunorubicin and rebecamycin as novel claudin modulators, which can enhance tight junction (TJ) barrier function in intestinal cells. Daunorubicin and rebeccamycin stimulate ATM and ATR kinases in the nucleus, resulting in activation of the downstream molecule, Chk1. Activated Chk1 increases claudin-5 expression, and the product of claudin-5 transitions to TJ following enhanced TJ-barrier. Furthermore, we constituted claudin-2 reporter system, and identified novel claudin-2 modulators from chemical library. In the future, we will investigate therapeutic effect of multiple claudin modulators for an inflammatory bowel disease.
