Green Tea Extract and Cancer Inhibition

Scientists from UCLA (Los Angeles, California) used gel electrophoresis followed by liquid chromatography–mass spectrometry (LC–MS) to analyze proteins extracted from lung cancer cells that had been incubated for 24 h with a green tea extract. Their efforts were directed at identifying increases or decreases in the abundance of several proteins following the treatment. The proteins were involved in functions such as calcium binding, cell cycle regulation, metabolism, detoxification, gene regulation, and cytoskeletal motility.
