Most malignancies displayed weak cytoplasmic positivity. Malignant melanoma testicular, prostate, colorectal and liver cancers showed moderate cytoplasmic immunoreactivity in some cases. Malignant glioma and lymphoma were mostly negative.
The Escherichia coli AlkB protein protects against the cytotoxicity of methylating agents by repair of the specific DNA lesions generated in single-stranded DNA. ALKBH2 (MIM 610602) and ALKBH3 are E. coli AlkB homologs that catalyze the removal of 1-methyladenine and 3-methylcytosine (Duncan et al., 2002 [PubMed 12486230]).[supplied by OMIM, Mar 2008]
