Hypothesis

Is there a relationship between glutathione-s-transferase pi expression and drug resistance in leukaemia patients?

Conclusion

Increased expression of GST pi is observed in various leukaemia types, but its relationship with drug resistance mechanisms is complex and not fully understood.

Supporting Evidence

  • Increased GST pi expression was found in 8 of 9 MDS patients.
  • 12 of 18 AML patients showed elevated GST pi levels.
  • 24 of 32 CLL patients had increased GST pi expression in peripheral blood.

Takeaway

This study looked at how a specific protein, GST pi, behaves in leukaemia patients and found that it can be higher in sick people, but it doesn't always mean they will resist treatment.

Methodology

RNA slot blotting techniques were used to investigate GST pi expression in blood and bone marrow samples from normal subjects and leukaemia patients.

Limitations

The study lacked adequate controls for normal blast cells and could not demonstrate gene amplification of GST pi in patient material.

Participant Demographics

Included 10 normal subjects (4 men, 6 women) aged 23 to 83 years, and patients with MDS, AML, and CLL.
