Consistent with the in vitro findings, administration of curcumol alone had negligible effects on the burdened tumors until high dosage (50 mg kg−1), whereas co‐treatment with curcumol and TRAIL induced drastic anticancer effects in dose‐dependent manners (Figure 2A), as indicated by tumor grow curve (Figure 2B) and tumor weights (Figure 2C). The gene discussed is TNFSF10; the disease is neoplasm.
