초록
In Korea, Rhus verniciflua Stokes is used to purge hardness, alleviate blood stasis, and treat cancer. However, the mechanisms of related anti-cancer activity are not fully understood in human cancer cells. This study investigated the anti-cancer effects and mechanisms of Rhus verniciflua Stokes on MDA-MB-231 human breast cancer cells and found that treatment with a Rhus verniciflua Stokes extract resulted in time- and concentration-responses that indicated growth inhibition of breast cancer cells by induced apoptosis. This was followed by a decrease in mitochondrial membrane potential; the activation of caspase-3, -8, and -9; and the up-regulation of tBid. Caspase-dependent apoptosis was induced through the inhibition of phosphatidylinositol 3-kinase (PI3K) and the Akt signaling pathway. This study provides evidence that Rhus verniciflua Stokes might be useful for the treatment of breast cancer.
Abstract
In Korea, Rhus verniciflua Stokes is used to purge hardness, alleviate blood stasis, and treat cancer.

This was followed by a decrease in mitochondrial membrane potential; the activation of caspase-3, -8, and -9; and the up-regulation of tBid. Caspase-dependent apoptosis was induced through the inhibition of phosphatidylinositol 3-kinase (PI3K) and the Akt signaling pathway. This study provides evidence that Rhus verniciflua Stokes might be useful for the treatment of breast cancer.
