Narrator: This is Science Today. A UCLA Jonsson Cancer Center study offers new insight into how green tea extract has potential as an anti-cancer agent. Jian Rao, an associate professor of epidemiology and pathology, says their study focused on bladder cancer cell lines.
Rao: We use a unique model system. These cell lines are both from the same individuals, so they genetically are similar. One can produce tumor the other one cannot. So, when you compare these two cell lines, we can learn quite a bit of biology to study the cancer mechanisms.
Narrator: Rao says the main finding of their study is that green tea extract selectively affects the cancer cells, but not the normal cells.
Rao: Furthermore, we demonstrate that the green tea affects the movement of the cell and also, we show the mechanisms of how that affects the movement of the cells. This is important clinically because more than likely green tea either is used as a drug to prevent cancer or can be used to treat the cancer patient.
