ABSTRACT
OBJECTIVE@#To study the relationship of the expressions of p53 and mdm2 in leukoplakia cancer.@*METHODS@#RT-PCR was used to detect the mRNA of p53, mdm2 in patients with leukoplakia cancer. The frequencies of p53, mdm2 in peripheral blood were detected by flow cytometric analysis.@*RESULTS@#The expression of p53mRNA in normal oral mucosa, simple oral leukoplakia, no-simple oral leukoplakia and leukoplakia cancer were 7.7%, 27.3%,33.3%, 56.8%, respectively. The frequencies of p53 in normal oral mucosa, simple oral leukoplakia, no-simple oral leukoplakia and leukoplakia cancer were (0.3±0.1)%, (1.6±0.9)%, (1.9±1.1)%, (3.4±1.8)%. The expression of mdm2 mRNA in normal oral mucosa, simple oral leukoplakia, no-simple oral leukoplakia and leukoplakia cancer were 0.0%, 6.8%, 11.1%, 37.8%, respectively. The frequencies of mdm2 in normal oral mucosa, simple oral leukoplakia, no-simple oral leukoplakia and leukoplakia cancer were (0.1±0.1)%, (0.8±0.6)%, (1.2±0.8)%, (1.2±0.8)%. There was a positively correlation between p53 mRNA and mdm2 mRNA.@*CONCLUSIONS@#The positive rate of p53 and mdm2 cells in the peripheral blood increases in patients with leukoplakia cancer tissue and has positive correlation with the severity of leukoplakia cancer.
