Outline of Final Research Achievements

Search for stem cells modulators has been done using screening system of natural resources extracts library. Bioactive natural products which bind on Hes1 (bHLH factor), GLI1 (Hedgehog signaling transcriptional factor) and NICD (Notch signaling transcriptional factor ) were efficiently found by using “target protein oriented natural products isolation (TPO-NAPI)”. In addition, bioactivity fractionation using cell-based reporter assay gave Notch signal inhibitors such as uscharin.
