We demonstrate that decursin induces apoptosis via regulation of cyclooxygenase-2 (COX-2) and survivin in leukemic KBM-5 cells. By activating an apoptotic machinery, decursin is cytotoxic to KBM-5 cells. In this apoptotic process, decursin can activate caspase family members and triggers PARP cleavage. At the same time, the expression of COX-2 and survivin in the cells is downregulated. Furthermore,...
Isorhamnetin is a flavanoid present in plants of the Polygonaceae family and is also an immediate metabolite of quercetin in mammals. Since the plasma level of isorhamnetin is maintained longer than quercetin, isorhamnetin may be a key metabolite to mediate the anti-tumor effect of quercetin. In the present study, we investigated the apoptotic mechanism of isorhamnetin in Lewis lung cancer (LLC) cells...
