title: The antiproliferative activity of saponin-enriched fraction from Bupleurum Kaoi is through Fas-dependent apoptotic pathway in human non-small cell lung cancer A549 cells.
abstract: Bupleuri Radix (Chai-hu in Chinese and Saiko in Japanese) is one of the most important traditional Chinese crude drugs for treating hepatitis malaria and intermittent fever. B. kaoi is one of the Bupleurum spp. families locally found in Taiwan. The effects of saponin-enriched fraction (SEF) from Bupleurum Kaoi in human non-small cell lung cancer A549 cells were investigated in this study. An enhancement in Fas and its two forms of ligands, membrane-bound Fas ligand (mFasL) and soluble Fas ligand (sFasL), was responsible for the apoptotic effect induced by SEF. Taken together, our study suggests that the activity of the Fas/Fas ligand apoptotic system may participate in the antiproliferative activity of SEF in A549 cells.
