Comprehensive Analysis of MGMT Promoter Methylation: Correlation with MGMT Expression and Clinical Response in GBM
O⁶-methylguanine DNA-methyltransferase (MGMT) promoter methylation has been identified as a potential prognostic marker for glioblastoma patients. The relationship between the exact site of promoter methylation and its effect on gene silencing, and the patient's subsequent response to therapy, is still being defined. The aim of this study was to comprehensively characterize cytosine-guanine (Cp...
متن کاملCorrelation of MGMT promoter methylation status with gene and protein expression levels in glioblastoma
OBJECTIVES 1) To correlate the methylation status of the O6-methylguanine-DNA-methyltransferase (MGMT) promoter to its gene and protein expression levels in glioblastoma and 2) to determine the most reliable method for using MGMT to predict the response to adjuvant therapy in patients with glioblastoma. BACKGROUND The MGMT gene is epigenetically silenced by promoter hypermethylation in glioma...
متن کاملMethylation status of MGMT gene promoter in meningiomas.
Meningiomas are usually cured by surgical resection. However, approximately 10% are characterized by more aggressive clinical behavior and higher risk of recurrence. Typically, recurrent meningiomas require further surgical resection followed, in some cases, by radiotherapy. To date, no chemotherapeutic agent has proven to be effective in either preventing or treating recurrence. The alkylating...
متن کاملCorrelation of ER, PR, HER- 2 and P53 Immunoreactions with Clinico-Pathological Features in Breast Cancer
Background and Objectives: The most prevalent malignancy among women is known to be breast cancer (BC). Several factors contribute to determining tumor prognosis and treatment strategies. In this study, the frequency and relevance of these factors are discussed. Materials and Methods: This cross-sectional study was carried out on 214 patients with BC, who referred to the Cancer Institute of...
متن کاملCorrelation of O6-methylguanine methyltransferase (MGMT) promoter methylation with clinical outcomes in glioblastoma and clinical strategies to modulate MGMT activity.
Resistance to alkylating agents via direct DNA repair by O(6)-methylguanine methyltransferase (MGMT) remains a significant barrier to the successful treatment of patients with malignant glioma. The relative expression of MGMT in the tumor may determine response to alkylating agents, and epigenetic silencing of the MGMT gene by promoter methylation plays an important role in regulating MGMT expr...
