Hypothesis

The study investigates the regulatory effects of the tumor-suppressing gene PTEN on the mTOR signaling pathway and its impact on the growth inhibition and apoptosis of K562 cells.

Conclusion

PTEN and rapamycin inhibit mTOR expression, suggesting a potential synergistic effect on leukemia treatment.

Supporting Evidence

  • PTEN gene transfection significantly inhibited K562 cell growth.
  • Rapamycin treatment combined with PTEN transfection led to a higher apoptosis rate in K562 cells.
  • The expression levels of PTEN mRNA increased after transfection.
  • mTOR mRNA levels decreased in K562 cells after PTEN transfection.

Takeaway

Scientists found that a gene called PTEN and a drug called rapamycin can work together to stop cancer cells from growing.

Methodology

K562 cells were transfected with an adenovirus-PTEN vector and treated with rapamycin, followed by measuring cell proliferation and apoptosis.
