MUTYH Activity Maintains Telomere Stability in Response to Chronic Telomeric 8-Oxoguanine Damage in Cancer Cells

Telomeres are highly susceptible to oxidative DNA damage, particularly 8-oxoguanine (8-oxoG), which is processed by glycosylase-initiated base excision repair (BER). OGG1 removes 8-oxoG opposite C, and MUTYH removes A misinserted opposite 8-oxoG to prevent mutations. While OGG1 h...
