Herceptin drug and breast cancer cell. Molecular model of Herceptin (Trastuzumab),showing the molecule's secondary structure,seen as alpha helices (coils) and beta sheets (arrows). A coloured scanning electron micrograph (SEM) of a breast cancer cell is at lower left (blue). Herceptin binds to HER2 (human epidermal growth factor receptor 2),a receptor that is over-expressed in some breast cancer cells,making them grow faster and more likely to spread. Herceptin blocks HER2,which kills the breast cancer cells. Around a fifth of breast cancers result from cells that over-express HER2,making them viable for Herceptin treatment | |
