Hypothesis
This study aims to identify the pattern of GST expression during renal embryogenesis and to see if Wilms' tumour shows similar expression to fetal kidney.
Conclusion
The study demonstrated a difference in GST expression between fetal kidney and Wilms' tumour blastema.
Supporting Evidence
- GST pi was the predominant isoenzyme in the fetal human kidney.
- Most cases of Wilms' tumours showed GST pi in both epithelial structures and undifferentiated blastema.
- GST alpha was found in only one case of Wilms' tumour.
Takeaway
The study looked at how certain proteins behave in developing kidneys and a type of childhood cancer, finding that they act differently.
Methodology
The study used immunohistochemistry to assess GST isoenzyme expression in tissue samples from fetal kidneys and Wilms' tumours.
Limitations
The study did not include patients who had received previous radiotherapy or chemotherapy, which may limit the generalizability of the findings.
Participant Demographics
Included 13 kidneys from aborted fetuses to 14 years of age and 15 cases of Wilms' tumour.
