Mouse Ogg1 encodes OGG1, a DNA glycosylase that initiates base excision repair by recognizing and excising 8-oxoguanine lesions generated by reactive oxygen species. This activity prevents mutagenic G:C→T:A transversions and preserves genome stability during replication and transcription. OGG1 functions within oxidative stress response networks and coordinates with downstream BER enzymes to restore DNA integrity. Altered OGG1 activity has been linked to increased oxidative DNA damage burden and is frequently studied in contexts such as inflammation, metabolic stress, neurodegeneration, and carcinogenesis models.
OGG1 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Ogg1 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Ogg1. When directed to adjacent sites on opposite DNA strands, the two nickases generate offset single-strand nicks that together produce a staggered double-strand break, requiring coordinated on-target activity from both guides. The resulting DNA break is resolved by endogenous cellular repair pathways, most commonly through non-homologous end joining (NHEJ), leading to insertions or deletions that disrupt Ogg1 function. By requiring dual sgRNA engagement at the target locus, the double nicking approach enhances editing specificity and provides a complementary CRISPR strategy for applications where additional control over targeting precision is desired.
To support efficient identification of edited cells, one plasmid encodes GFP for fluorescent visualization of transfected populations, while the companion plasmid carries a puromycin resistance gene for antibiotic selection. Together, these features support efficient enrichment of co-transfected populations and simplify the validation of Ogg1-disrupted clones.
