Abstract:
Objective: To study the relationship of the expressions of new apoptosis-related gene (PDCD)5 and p53 in oral normal mucosa, oral leukoplakia and oral squamous cell carcinoma. Methods: The expressions of PDCD5 and p53 were observed separately in 17 samples of oral normal mucosa, 60 of oral leukoplakia, and 30 of oral squamous cell carcinoma by Immunohistochemical means. Results: PDCD5 positive rate in oral normal mucosa was 88.2%, in oral leukoplakia was 63.3%, and in oral squamous cell carcinoma was 30%. P53 positive rate in oral normal mucosa was 0, in oral leukoplakia was (31.7%), and in oral squamous cell carcinoma was 60%. There was a negative relationship between (PDCD5) SII and P53 SII in every lesion. Conclusion: It suggests that both PDCD5 and p53 could be used as molecular markers of carcinogenesis for oral epithelium.
