Hypothesis
What genes are down-regulated during lung cancer progression?
Conclusion
The study identified several genes that are differentially expressed during lung cancer progression, confirming some previously known results.
Supporting Evidence
- The study used cDNA arrays to analyze gene expression in lung cancer patients.
- 14 genes were identified as differentially regulated between stage 1 and stage 2 NSCLC.
- Quantitative RT-PCR confirmed the differential expression of 8 out of 14 genes analyzed.
Takeaway
Researchers looked at patients with early-stage lung cancer to find out which genes are less active as the cancer grows. They found some important genes that change in expression.
Methodology
cDNA array experiments and quantitative RT-PCR were used to analyze gene expression in lung cancer patients.
Potential Biases
Patients who did not survive beyond 60 days after surgery were excluded to avoid bias from peri-operative death.
Limitations
Not all differences found by the array were reproducible with quantitative RT-PCR, indicating potential methodological limitations.
