  • Scientists at a university now study how cells send signals.
  • Cells use networks of proteins to sense their environment.
  • One important protein called mTOR controls different cell tasks.
  • mTOR works as two parts that do different jobs.
  • Many drugs stop both parts of mTOR at the same time.
  • Stopping one part can make cancer cells more resistant to treatment.
  • The new study shows we could block only one part.
  • This idea may help scientists design better cancer drugs in future.
