Hypothesis
DNA replication-initiation proteins are useful biomarkers for early detection and diagnosis of squamous cell carcinoma (SCC) of the tongue.
Conclusion
The study found that mRNA levels of certain DNA replication-initiation proteins are higher in malignant lesions compared to precancerous conditions, indicating their potential as biomarkers for early detection of SCC.
Supporting Evidence
- The expression levels of CDC6, CDT1, MCM2, and CDC45 were significantly higher in malignant SCC than in mild precancerous dysplasia.
- A strong association was found between CDC6 and CDT1, and between MCM2 and CDC45 expression.
- MCM2 and CDC45 showed higher accuracy for distinguishing dysplasia from SCC compared to CDC6 and CDT1.
Takeaway
Scientists looked at special proteins in tongue tissue to see if they can help find cancer early. They found that higher levels of these proteins mean a higher chance of cancer.
Methodology
The study analyzed mRNA expression of CDC6, CDT1, MCM2, and CDC45 in tongue tissues using quantitative real-time PCR.
