MGMT Gene Function
O-6-Methylguanine-DNA Methyltransferase
Overview
MGMT directly reverses O6-alkylguanine DNA damage by transferring the alkyl group to itself. Promoter methylation can reduce MGMT expression in glioma, but methylation assays, cut-offs and tumour context must remain attached to any result.
Molecular Mechanism
Detailed mechanism data is not yet available for MGMT.
Key Pathways
- ·Direct DNA-damage reversal

Research Activity
MGMT is an actively studied target: about 40+ clinical trials that mention it are currently recruiting on ClinicalTrials.gov. Trial activity reflects research interest, not proven benefit — designs, endpoints and populations vary widely.

Common Questions About MGMT
What does MGMT do?
MGMT participates in Direct DNA-damage reversal, Alkylation-damage response, Epigenetic gene regulation. MGMT directly reverses O6-alkylguanine DNA damage by transferring the alkyl group to itself. Promoter methylation can reduce MGMT expression in glioma, but methylation assays, cut-offs and tumour context must remain attached to any result.
Why is MGMT relevant to cancer research?
Its reported relevance includes Glioblastoma, Diffuse glioma, Alkylator-treated cancers. The exact alteration, assay and disease context determine what a result can support.
