Mouse Casp8 encodes caspase-8, an initiator cysteine protease that couples death receptor engagement to downstream caspase cascades and apoptotic execution. Beyond apoptosis, caspase-8 modulates NF-κB-linked inflammatory signaling and restrains necroptosis by regulating RIPK1/RIPK3–MLKL pathway activation, thereby shaping innate immune responses and cell fate decisions. Dysregulated caspase-8 activity or expression is associated with altered lymphocyte homeostasis, aberrant cytokine signaling, and defects in tissue remodeling. These functions make Casp8 a key node for studying extrinsic apoptosis, inflammatory pathway crosstalk, and programmed cell death balance in mouse models of immune and neuroinflammatory phenotypes.
caspase-8 Double Nickase Plasmid (m) consists of a matched pair of plasmids engineered for high-specificity editing of the Casp8 locus in mouse cell lines. Each plasmid expresses a Cas9 D10A nickase and a distinct sgRNA targeting opposite DNA strands within Casp8. 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 Casp8 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 Casp8-disrupted clones.
