Another anti-cancer activity of apigenin has been was shown in breast cancer cells. Apigenin was found to effectively induce
apoptotic cell death and overproduction of reactive oxygen species in breast
cancer cells, MCF-7 cells, in the article recently published in Scanning
journal.
Apigenin induced MCF-7 cell apoptosis-associated reactive oxygen species.
Abstract of the article
Apigenin is a flavonoid, which has been proved to possess
effective anti-cancer bioactivities against variety of cell lines. However,
little is known about its effect on the cell-surface and the interaction
between cell-surface and the reacting drug.
In this study, human breast cancer
line (MCF-7) was selected to be as a cell model to investigate the effects of
apigenin on cell growth, proliferation, apoptosis, cellular morphology, etc.
MTT assay showed that the growth inhibition induced by apigenin was in a
dose-dependent manner when treated with different concentrations of apigenin
while had little cytotoxic effects on human normal cells (MCF-10A).
Fluorescence-based flow cytometry was used to detect cellular apoptosis and ROS
production.
The results showed that 80 µM apigenin could effectively
induce apoptosis and overproduction of ROS in MCF-7 cells. Here, atomic force
microscopy (AFM) was utilized to detect the shapes and membrane structures of
MCF-7 cells at cellular or subcellular level.
The results showed that the control MCF-7 cells presented
typical elongated-spindle shapes with abundant pseudopodia, while after treated
with apigenin, the cells shrunk and became round, the pseudopodia diminished.
Moreover, the images of ultrastructure indicated that the cell membrane was
composed of nanoparticles of 49 nm, but with the treated concentrations of
apigenin increasing, the sizes of membrane particles significantly increased to
400 nm.
These results can improve our understanding of apigenin,
which can be potentially developed as a new agent for treatment of cancers.
