Definitions for "Hormone receptors"
Hormone receptors are proteins residing within the cell which specifically bind to the appropriate hormone. This hormone receptor complex subsequently stimulates the cell to undergo a physiological function such as cell division. In women with breast cancer, these receptors are present in approximately 50% of all women and are powerful prognostic indicators of survival and response to hormone (or antihormonal) therapy.
Special molecules on cells that interpret the signal being sent by hormones.
molecules that carry hormones into the cell nucleus. Hormone receptors are present in both normal breast cells and cancerous breast cells.
