Human GLO1 encodes glyoxalase I, a cytosolic metalloenzyme that catalyzes the glutathione-dependent detoxification of methylglyoxal by converting hemithioacetal intermediates to S‑D‑lactoylglutathione. This activity is central to the glyoxalase system that limits accumulation of reactive dicarbonyls and downstream advanced glycation end products, linking GLO1 to cellular redox balance, proteostasis, and metabolic stress responses. Perturbation of glyoxalase I function can alter glycolysis-associated carbonyl stress and influence signaling and damage pathways involving glycation, oxidative stress, and inflammation. Changes in GLO1 expression or activity have been studied in contexts such as diabetes-related complications, neurodegeneration, and tumor metabolism as a readout of dicarbonyl detox capacity.
Glyoxalase I Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the GLO1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within GLO1. 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 GLO1 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 GLO1-disrupted clones.
