Hypothesis
The study investigates the expression of genes involved in multidrug resistance in various types of leukaemias.
Conclusion
The expression of the mdrl/P-glycoprotein gene is significantly elevated in relapsed leukaemias, indicating a potential mechanism for chemotherapy resistance.
Supporting Evidence
- Significant positive correlations were found for topoisomerase I and histone 3.1 gene expression levels.
- Elevated mdrl/P-glycoprotein expression was observed in relapsed leukaemias.
- Topoisomerase II mRNA levels were variable but often strong in acute leukaemias.
- Chronic lymphocytic leukaemias showed moderate mdrl expression levels.
Takeaway
This study looks at how certain genes behave in leukaemia cells, especially when they come back after treatment, which helps us understand why some treatments don't work.
Methodology
The study used slot-blot and Northern-blot hybridisation experiments to analyze gene expression in leukaemia cell samples.
Limitations
RNA preparation was not possible for some samples due to small sample size.
Participant Demographics
The study included both adult and childhood leukaemia patients.
