MGMT Methylation Analysis

MGMT Promoter Methylation In Glioblastoma

Glioblastoma is the most common form of primary brain cancer in adults, with a median survival rate of 12-15 months. Although nearly all glioblastomas recur, initial treatments may keep the tumor controlled for months or even years. MGMT promoter methylation has been shown to be associated with improved outcomes in glioblastoma patients, especially after treatment with alkylating chemotherapy. To quantify CpG methylation within the MGMT gene promoter, researchers used bisulfite modification of tumor DNA and real-time PCR. Therefore, our MGMT methylation tests can help guide clinicians with treatment decisions.

MGMT Methylation Panel Available as Kits or Services

Select the full panel, one assay or design a combination of assays in the format that matches your project.

O6-methylguanine-DNA methyltransferase, known as MGMT, repairs damaged guanine nucleotides by transferring the methyl at O6 site of guanine to its cysteine residues, thus avoiding cell death, gene mutation and tumorigenesis caused by alkylating agents.

Clinical Significance

In the treatment of glioblastoma multiforme, methylation of the O6-methylguanine DNA methyltransferase (MGMT) promoter has emerged as a major prognostic predictor. Methylation (or hypermethylation) of the MGMT gene promoter inhibits or inactivates the MGMT enzyme’s normal DNA-repair function, making tumors more vulnerable to radiotherapy or alkylating agent-based therapy. MGMT methylation has been reported in other tumors including lung, lymphoma, and colorectal and alkylating agents and/or radiation therapy may be considered in these cases.

MGMT Gene Methylation and Response to Alkylating Agents

Human, MGMT – Assay ID: ASY470-FS1

Human, MGMT - ASY470 Assay - EpigenDx

Gene methylation is a DNA-based gene expression regulation method. Methylation levels in gene promoter regions can be aberrant or elevated in cancer (hypermethylated). This epigenetic change to DNA prevents the gene from performing its function, resulting in the protein encoded by the gene not being created or being produced at a low level.

O6-methylguanine-DNA methyltransferase (MGMT) is an important DNA repair enzyme in a healthy person. During the progression of cancer, this gene’s activity or function is usually lost. When the MGMT gene or function is lost, an individual is more vulnerable to DNA damage and tumor growth. However, once the cancer has progressed, the presence or absence of MGMT activity is no longer a factor.
