Incidence and persistence of 8-oxo-7,8-dihydroguanine within a hairpin intermediate exacerbates a toxic oxidation cycle associated with trinucleotide repeat expansion
The repair protein 8-oxo-7,8-dihydroguanine glycosylase (OGG1) initiates base excision repair (BER) in mammalian cells by removing the oxidized base 8-oxo-7,8-dihydroguanine (8-oxoG) from DNA. Interestingly, OGG1 has been implicated in somatic expansion of the trinucleotide repeat (TNR) sequence CAG...
