Using a special virus to deliver a genetic tool that blocks ER-α gene activity successfully lowered ER-α levels in liver cancer cells within a day or two.

Using a virus to deliver the genetic tool worked better than other methods, with about 80% of liver cancer cells taking up the treatment successfully.

When using a control that doesn't block ER-α, there was no change in cancer cell growth, invasion, or death compared to normal cells.
