Novel technique switches triple-negative breast cancer cells to hormone-receptor positive cells

Within many hormone-receptor positive breast cancers lives a subpopulation of receptor-negative cells – knock down the hormone-receptor positive cells with anti-estrogen drugs and you may inadvertently promote tumor takeover by more dangerous, receptor-negative cells. A study recently published in the Proceedings of the National Academy of Sciences describes how to switch these receptor-negative cells back to a state that can be targeted by existing hormone therapies.
