Human DNASE1 encodes DNase I, a secreted endonuclease that cleaves extracellular and chromatin-associated DNA, contributing to nucleic acid clearance and regulation of inflammatory signaling triggered by self-DNA. DNase I activity influences processes linked to apoptosis-associated DNA fragmentation, neutrophil extracellular trap turnover, and prevention of aberrant innate immune activation through DNA-sensing pathways. Altered DNASE1 expression or activity has been associated with impaired clearance of circulating DNA and immune dysregulation, contexts frequently investigated in autoimmunity and tissue injury models. In cancer and stromal biology, DNase I–mediated DNA turnover is also studied for its effects on the tumor microenvironment and extracellular nucleic acid signaling.
DNase I Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the DNASE1 locus in human cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within DNASE1. 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 DNASE1 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 DNASE1-disrupted clones.
