Two new, powerful small molecules may be able to kill cancers that other therapies can't

Scientists have identified and developed two potent small molecules that appear to suppress tumor growth in multiple cancers even when other treatments cease to work, possibly due to the development of drug resistance. Called CS1 and CS2, these cancer inhibitor compounds are part of a protein known as ''fat mass and obesity-associated protein.'' This FTO protein plays a critical role in cancer development and progression, primarily because it regulates cancer stem cells and immune evasion.
