Abstract
Objective: To investigate the expression of K-ras in human laryngeal squamous cell carcinoma cell lines (Hep-2) and its significance for establishing a solid foundation for further study of the relationship between human laryngeal squamous cell carcinoma and K-ras gene point mutations. Methods: The expression of K-ras in human laryngeal squamous cell carcinoma cell lines (Hep-2) and human pancreatic carcinoma cell lines (MIAPaCa-2) was detected by using RT-PCR. Results: The expression of K-ras mRNA in Hep-2 and MIAPaCa-2 was strong and positive. Conclusion: The expression of K-ras mRNA in human laryngeal squamous cell carcinoma cell lines (Hep-2) is positive. Development of laryngeal carcinoma might be related to the activation of K-ras gene point mutation.
