| Outline of Final Research Achievements |
This study aims to find useful low-molecular compounds by screening natural products having effects on intracellular signals that control the development and recurrence of cancer. In particular, screening studies were carried out targeting several intracellular signals that have essential roles of treatment-resistance of cancer cells and acquiring pluripotency of stem cells. As a result, we have isolated many useful active compounds that have inhibitory effects on Wnt and Hedgehog signal pathways, and also obtained natural products having TRAIL resistance overcoming activity. Using several active compounds thus isolated, we investigated their effects on the expression of various proteins and mRNA involved in cancer progression, the influence of inducing apoptosis or cell viability. We have also elucidated the target molecules with respect to the remarkable active compound, fuligocandin B, which has TRAIL-overcoming activity obtained from a myxomycete species.
