Tumour Hypoglycaemia and IGFII mRNA Levels
Author Information
Author(s): P.N. Schofield, H. Connor, R.C. Turner, J. Zapf
Primary Institution: University of Oxford
Hypothesis
Is there a relationship between elevated tumour IGFII mRNA levels and reduced plasma somatomedins in patients with tumour hypoglycaemia?
Conclusion
The study found that while IGFII mRNA levels were significantly elevated in the tumour, the corresponding peptide levels in serum and tumour cyst fluid were suppressed.
Supporting Evidence
- IGFII mRNA levels were elevated around 30-fold compared to normal tissue.
- Plasma samples showed suppression of IGF activity post-operation.
- Histology confirmed the presence of a malignant sarcoma.
Takeaway
In a patient with a tumour causing low blood sugar, the tumour had a lot of a specific messenger RNA, but not enough of the protein that usually comes from it.
Methodology
The study involved measuring IGF mRNA levels in tumour tissue and assessing IGF concentrations in serum and tumour cyst fluid.
Limitations
The study is based on a single case, limiting the generalizability of the findings.
Participant Demographics
A 57-year-old female patient with a para-ovarian sarcoma.
