Q: How does AFINITOR work? 

A: Tuberous sclerosis cells typically have changes in their TSC1 or TSC2 genes that make them different from normal cells. These gene changes might cause the cell to make too much of a protein called mammalian target of rapamycin (mTOR). This, in turn, might make the cell grow and divide too quickly, causing a tumor to form. AFINITOR targets mTOR, blocking its effects and thereby reducing the growth of tumor cells. The blocking of mTOR by AFINITOR has been shown to slow the increase in the number of tumor cells and decrease the creation of new blood vessels within the tumor. This was based on data obtained in a laboratory environment as well as studies within living cells.
