General Description of O-Methylguanine-DNA-Methyltransferase .
O(6)-methylguanine-DNA-methyltransferase (MGMT) is a 22 kDa human DNA repair protein that removes O(6)-alkylguanine DNA adducts. MGMT acts as a suicide acceptor protein repairing the DNA by accepting alkyl groups and consequently inactivating itself. This antibody stains all mantle zone lymphocytes and 50% of germinal center lymphocytes. Basaloid epithelial cells of tonsil squamous mucosa are also stained positive with this antibody.

O-Methylguanine-DNA-Methyltransferase Information for Pathologists


O6-methylguanine-DNA methyltransferase, a DNA repair enzyme at 10q26. Removes DNA alkylation adducts from mutagenic O(6)-methylguanine, which both:. Repairs damaged DNA and protects normal cells from carcinogens, and. Contributes to drug resistance of gliomas to alkylating agents by protecting tumor cells from alkylating agents such as temozolomide. MGMT promoter hypermethylation and epigenetic silencing often occur as early events in carcinogenesis.

Notable Clinical Features:

General. Polymorphisms in MGMT gene may be cancer risk factor (Tumour Biol 2013;34:3227). CNS, diffuse glioma and glioblastoma:. Methylation of promoter region of MGMT is associated with favorable outcome in glioblastoma patients undergoing chemotherapy with alkylating agents (median survival 22 months with versus 13 months without methylated promoter) (Onco Targets Ther 2013;6:1363). Methylation may not have favorable outcome in glioblastoma patients >50 years of age (Mod Pathol 2013;26:922), although recommended to consider use of temozolamide in elderly regardless of MGMT status (Clin Neurol Neurosurg 2013;115:1375, PLoS One 2013;8:e74242).

Common Uses By Pathologists:

Methylation status may be useful to oncologists planning treatment . Microscopic (histologic) images Images hosted on other servers:. Missing Image. Hepatocellular carcinoma with HIV (fig A / B).
