The expression of p53, mgmt and egfr in brain glioma and clinical significance

Abstract

In order to discuss the expression of P53, MGMT (O6-methylguanine-DNA methyltransferase) and EGFR (epidermal growth factor receptor) in brain glioma and their clinical significance, this paper collected clinical features of 40 patients. We observed the expression of P53, MGMT and EGFR in samples using immuohisto-chemistry assay and analyzed their interaction, as well as their relationship to brain glioma. It was found that among 40 cases of brain glioma samples, cases with positive P53 expression accounted for 47.5%, and its expression in high-grade brain glioma was higher than in low-grade brain glioma (P less than 0.05); cases with positive MGMT expression accounted for 37.5%;, and its expression in high-grade glioma and low-grade brain glioma had no statistical significance (P>0.05); cases with positive EGFR expression accounted for 55%, and its expression in high-grade brain glioma was higher than in low-grade brain glioma (P less than 0.05); the expression of P53, MGMT and EGFT were not correlated to age, gender or size of tumor; P53 expression was negatively correlated to MGMT expression (P < 0.05) but positively correlated to EGFR expression (P < 0.05) demonstration that P53, EGFR and MGMT play important roles in the occurrence and development of brain glioma.
