CASP8 encodes caspase-8, an initiator caspase that couples death receptor signaling to apoptotic execution through proteolytic activation of downstream effector caspases. It is a core component of extrinsic apoptosis mediated by TNFRSF receptors such as FAS and TNFR1, and it also interfaces with innate immune pathways that govern inflammasome crosstalk and cytokine processing. Caspase-8 activity influences the balance between apoptosis, necroptosis, and inflammatory cell death by modulating RIPK1/RIPK3 signaling and cFLIP-dependent complex assembly. Dysregulation of CASP8 has been associated with altered immune homeostasis, defective lymphocyte apoptosis, and tumor cell survival mechanisms that affect sensitivity to death receptor ligands.
caspase-8 Double Nickase Plasmid (h) consists of a matched pair of plasmids engineered for high-specificity editing of the CASP8 locus in human 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.
