 | | Tamoxifen is currently the front-line drug to prevent breast cancer, but millions of women do not take it because of its potential to cause hot flashes, mood swings, sleep changes, blood clots and stroke, said Victoria Seewaldt, M.D., lead author of a tamoxifen study published in the November 18, 2004, issue of the journal Oncogene. |
 | | Tamoxifen's side effects are thought to be caused when genes in the nucleus are activated, so using drugs that target only the fast-acting pathway could eliminate unwanted side effects, she said. |
 | | Until now, scientists have believed that tamoxifen entered cells only in one way: by slowly leaking through a breast cell's outer membrane, idling in the cell until tamoxifen encounters an estrogen receptor in the nucleus, binding to it, and activating genes to cause cell-suicide. |
