Herbal plants are enriched with compounds with a wide range of biological activities. Furanodiene is a sesquiterpene isolated from Rhizoma Curcumae. Growing evidence shows furanodiene exhibits diversified activities of hepatoprotection, anti-inflammation, anti-angiogenesis, and anti-tumor. ⋯ Co-incubation induced the typical PARP cleavage or caspase 9 cleavages compared to individual agent. In addition, PPARγ activity inhibition by its antagonist T0070907 did not significantly reverse the enhanced effect of furanodiene and TAM suggesting that anti-cancer properties of combination were PPARγ independent. Our data indicated that furanodiene could enhance the growth inhibitory and pro-apoptotic activity of TAM by inducing cell cycle arrest and cell apoptosis via CDKs-cyclins and mitochondria-caspases-dependent, and PPARγ-independent signaling pathways in breast cancer cells, without contributions to the cytotoxicity of TAM.
