Hypothesis
The ret oncogene may play a role in the proliferation of neural crest cells.
Conclusion
The study found that a retroperitoneal tumor diagnosed as neuroblastoma developed in a transgenic mouse carrying the ret oncogene.
Supporting Evidence
- A retroperitoneal tumor developed in one of the 17 MT/ret transgenic founder mice.
- The tumor consisted of undifferentiated neuroblasts and differentiated ganglion cells.
- Expression of the ret transgene was observed at high levels in RNA from the tumor.
Takeaway
Scientists created special mice with a gene that might cause cancer, and one of them got a tumor called neuroblastoma.
Methodology
Transgenic mice were produced carrying a hybrid gene, and tumors were analyzed histologically and through various molecular techniques.
Limitations
The study only reports on one tumor from a small number of transgenic mice.
Participant Demographics
Transgenic mice, specifically 17 founder mice were studied.
