Hypothesis
Are the proto-oncogenes c-met and c-kit expressed in small cell lung cancer (SCLC) cell lines and xenografts?
Conclusion
The study found that c-met and c-kit are frequently expressed in SCLC, suggesting they may play important roles in the disease.
Supporting Evidence
- 22 out of 25 SCLC tumours expressed c-met mRNA.
- Coexpression of c-met and c-kit mRNA was found in 20 tumours.
- SCF mRNA was expressed in 19 of the examined tumours.
Takeaway
This study looked at cancer cells from patients and found that two important genes, c-met and c-kit, are often turned on in these cells, which might help them grow.
Methodology
The expression of c-met and c-kit mRNA and protein was examined in 25 SCLC cell lines and xenografts using Northern blotting and Western blotting.
Limitations
The study only examined a limited number of SCLC tumours and may not represent all cases.
Participant Demographics
The study included 25 SCLC tumours established from 20 patients.
