A hidden weakness in deadly cancers could lead to powerful new treatments
A UCLA study has identified a hidden Achilles' heel in aggressive small cell cancers that have resisted new treatments for decades. Scientists found that tumors lacking the RB gene become critically dependent on the protein E2F3 for survival. Blocking E2F3 shut down tumor growth in laboratory models, and existing FDA-approved drugs may be able to exploit this vulnerability. The discovery could pave the way for faster development of more effective therapies.
