PRDX1 encodes peroxiredoxin 1 (PRX I), a cytosolic thiol-dependent peroxidase that reduces hydrogen peroxide and organic hydroperoxides to maintain cellular redox homeostasis. By buffering reactive oxygen species, PRX I influences peroxide-mediated signal transduction and supports redox-sensitive pathways governing proliferation, apoptosis, and stress responses, including MAPK and NF-κB signaling. PRX I also contributes to protein thiol redox regulation through the peroxiredoxin–thioredoxin system and can affect cytoskeletal dynamics and DNA damage responses under oxidative stress. Dysregulated PRDX1 expression or oxidation state has been associated with altered inflammatory signaling, metabolic remodeling, and tumor biology, making it relevant for mechanistic studies of oxidative stress–linked disease processes.
PRX I Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the PRDX1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within PRDX1. 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 PRDX1 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 PRDX1-disrupted clones.
