Matrine, as a natural alkaloid isolated from the traditional herb medicine sophora flavescens, has been proved to possess excellent biological activities, including anticancer effects. Now, this research aims to assess the anticancer activities and the mechanism of matrine against esophageal cancer cells, we investigated the proliferative inhibition, apoptosis induction, as well as the underlying mechanism of matrine on esophageal cancer KYSE-150 cells. It was found that matrine could suppress KYSE-150 cell proliferation and significantly mediate cell apoptosis in a dose-dependent relation by increasing intracellular reactive oxygen species level and triggering mitochondrial membrane potential disruption. More precise mechanism studies demonstrated that matrine could up-regulate the expression of Bax proteins and down-regulate the expression of Bcl-2 proteins, as well as the activation about caspase-3, 8 and 9 in KYSE-150 cells. The morphological analysis of KYSE-150 cells exhibited that matrine could destroy the F-actin and nuclei structures and induce morphological damage with increased surface height distribution and roughness of cell membrane. These results not only demonstrated the potential anticancer activity mechanism of matrine at nanoscale, but also provide preliminary guidance for the treatment of esophageal cancer using matrine.
