Hypothesis
The study aims to assess the expression of the p21 oncoprotein in normal and malignant laryngeal tissues.
Conclusion
Overexpression of p21 protein is associated with a malignant phenotype in laryngeal cancer.
Supporting Evidence
- Varying p21 levels were found in normal mucosa and primary laryngeal cancers.
- Higher levels of p21 were found in neoplastic than in normal laryngeal tissue.
- Most of the tumour cells were immunostained for p21.
Takeaway
This study looked at a protein called p21 in throat cancer and found that higher levels of this protein are linked to cancer.
Methodology
Western blotting analysis was performed on tissue samples from normal laryngeal mucosa and primary laryngeal cancers.
Limitations
The study does not allow for evaluation of the prognostic role of p21 expression due to the small number of cases.
